There is a plethora of options that can be encompassed in KOA treatment regimes. Clinical decision support (CDS) tools that incorporate individual patient data have the capacity to tailor treatments to meet a patient's individual needs and assist with clinical decision-making. We aim to identify and evaluate CDS tools for individuals with KOA that use individualised prediction models to guide intervention decisions. A scoping review of the literature. A systematic search of six electronic databases, including Ovid Embase, Ovid Medline, Cochrane, CHINAL Ultimate, Scopus and Web of Science, was conducted for articles published between January 1, 2010 and May 17, 2024. Two reviewers independently screened articles and extracted data on study design, tool implementation and underlying prediction models. Eligible studies implemented personalised decision aids, designed to support clinical decisions regarding KOA interventions. The search yielded 5376 publications, of which 2445 were duplicates, leaving 2931 for screening. After title/abstract and full-text reviews, 14 studies were included in the final analysis, with one added through citation searching. Ten distinct decision aids were identified across the included studies. Most studies originated from the United States. Fewer than half of the decision aids included personalised information about non-surgical alternatives. Outcomes such as knee pain and physical function were the most commonly addressed, while psychosocial and financial impacts were rarely reported. Limited details were provided about the development and functionality of the underlying prediction models. Personalised decision aids for KOA show promise in supporting patient-centred decision-making. However, their clinical utility is constrained by limited transparency in model development and implementation. Future studies should emphasise the inclusion of non-surgical treatment options, early-stage KOA patients and personalised outcomes beyond pain and function to enhance their relevance and impact in clinical practice.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/41568289/", "type": "review", "institutions": [], "provenance": ["https://pubmed.ncbi.nlm.nih.gov/41568289/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=105027657263&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=105027657263&origin=inward", "scopusDoi": "10.1177/1759720x251407070"}, {"id": "PMID42632450", "title": "Multi-mOdal Training program to promote physical actIVity After sTrokE (MOTIVATE): Protocol for effectiveness and economic outcomes in a hybrid type 1 effectiveness-implementation randomised controlled trial.", "year": 2026, "doi": "10.1016/j.cct.2026.108441", "url": "https://pubmed.ncbi.nlm.nih.gov/42632450/", "authors": ["Thilarajah, Shamala", "Pua, Yong Hao", "De Silva, Deidre Anne", "Thumboo, Julian", "Low, Lian Leng", "Hollis, Jenna", "Bird, Marie-Louise", "Clark, Ross A", "Wang, Juliana", "Kaur, Pevenpreet", "Kwah, Li Khim"], "venue": "Contemporary Clinical Trials", "abstract": "BACKGROUND: Physical activity (PA) is a key modifiable behaviour for secondary prevention and recovery after stroke, yet effective and scalable PA interventions remain limited. MOTIVATE (Multi-mOdal Training program to promote physical actIVity After sTrokE) is a theory-informed, co-designed behaviour change intervention to address these gaps.\n\nAIM: To determine whether MOTIVATE increases device-measured moderate-to-vigorous physical activity (MVPA) at 3 and 6 months among community-dwelling stroke survivors, compared with general PA information, and whether it is cost-effective. Implementation outcomes are collected concurrently and reported in a separate process evaluation protocol.\n\nMETHODS: MOTIVATE is a hybrid type 1 effectiveness-implementation, phase III randomised controlled trial with concealed allocation, assessor-blinded outcomes and intention-to-treat analysis. Adults aged ≥21 years, ≥6 months post-stroke, living at home, and ambulant (with or without an aid) are eligible and randomised to MOTIVATE or general PA information. Outcomes are assessed at baseline, 3 and 6 months, alongside process and economic evaluations. Recruitment of 120 participants provides 80% power to detect a 10-min/day MVPA difference, allowing for 20% attrition.\n\nSTUDY OUTCOMES: The primary outcome is average daily MVPA minutes measured using Fitbit Inspire 3. Secondary outcomes include additional PA measures, physical function, participation, and quality of life, analysed using Bayesian mixed-effects models. Self-efficacy, fatigue, mood, and sleep are collected to explore hypothesised mechanisms via post-trial mediation/moderation analyses, reported separately. Health service utilisation is collected for economic evaluation.\n\nDISCUSSION: MOTIVATE will provide new evidence on the effectiveness and cost-effectiveness of a co-designed, personalised behaviour change intervention to increase PA after stroke.\n\nTRIAL DESIGN: Individually randomised, parallel-group, superiority hybrid type 1 effectiveness-implementation trial (allocation ratio 1:1).\n\nPRIMARY PURPOSE: Secondary prevention/behaviour change.\n\nTARGET SAMPLE SIZE: 120 Participants.\n\nREGISTRATION: www.\n\nCLINICALTRIALS: gov; NCT06409351.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/42632450/", "type": "article", "institutions": [], "provenance": ["https://pubmed.ncbi.nlm.nih.gov/42632450/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=105048141376&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=105048141376&origin=inward", "scopusDoi": "10.1016/j.cct.2026.108441"}, {"id": "W7155205239", "title": "The Effect of Preterm Birth on Physical Activity for 9- to 12-Year-Old Children", "year": 2026, "doi": "10.1016/j.jpeds.2026.115115", "url": "https://doi.org/10.1016/j.jpeds.2026.115115", "authors": ["Kate L.

PA was measured using 7-day accelerometry and the Physical Activity Questionnaire for Older Children (PAQ-C). Imputation models were used to handle missing data as the total sample recruited at birth included 551 participants.\n\nRESULTS: Children born VPT had more stationary (mean difference (MD): 32 minutes, 95% CI 4, 60; P = .024) and screen time (MD: 25 minutes, 95% CI 0.2, 50; P = .048), and had lower PAQ-C scores (MD: -0.3, 95% CI -0.4, -0.1; P = .001) than term-born children. Children born MLPT completed more screen time (MD: 22 minutes, 95% CI 1, 43; P = .038) than term-born children. All children failed to meet moderate-vigorous PA recommendations (≥60 minutes/day), with 16.6 minutes on average observed across all participants.\n\nCONCLUSIONS: Children born VPT were more sedentary with lower PAQ-C scores, and both preterm groups (VPT and MLPT) had higher screen time than children born at term.

We propose an alternative assessment and scoring approach for the SPPB, and we compared the modified and the original SPPB on their discriminative and clinical value concerning the risk of prefrailty/frailty, probable sarcopenia, and restricted life-space mobility (RLSM).\n\nDESIGN: Cross-sectional study conducted from June 2018 to August 2023.\n\nSETTING AND PARTICIPANTS: A community-dwelling sample of 2331 participants [mean (SD), 66 (7.5) years; 71% women] completed a survey and fitness assessment.\n\nMETHODS: SPPB scores, FRAIL (fatigue, resistance, ambulation, illness, and loss of weight) scores, handgrip strength, and Life-Space Assessment scores were obtained from all participants. SPPB modifications involved (1) increasing the difficulty of the full-tandem balance test and (2) adopting a continuous scoring system. Participants with a FRAIL score ≥1, a weak handgrip strength (<18 kg for women and <28 kg for men), and a Life-Space Assessment <60 points were classified as having prefrailty/frailty, probable sarcopenia, and RLSM, respectively. Discriminative validity was evaluated using multivariable logistic regression and area-under-the-curve (AUC) analyses, whereas clinical utility was assessed using decision curve analysis.\n\nRESULTS: The proposed modifications significantly reduced the ceiling effect of the SPPB (original vs modified SPPB: 70% vs 27%, P < .001) and improved its discriminative validity for prefrailty/frailty, sarcopenia, and RLSM outcomes (AUC increments, 0.03-0.08; P values < .001). In decision curve analyses, these improvements translated to greater net benefit particularly in the 10% to 20% decision risk range.\n\nCONCLUSIONS AND IMPLICATIONS: Although requiring further validation in diverse populations and longitudinal studies, the proposed modifications to the SPPB have the potential to widen its scope of use and facilitate more accurate risk stratification and granular outcome monitoring in community-dwelling adults.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/41386281/", "type": "article", "institutions": [{"id": "https://openalex.org/I157582758", "name": "SingHealth", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Laura Tay", "Sapphire Lin", "Julian Thumboo", "Min-Xian Wang", "Sharon Jie-Yi Chew", "Teresa Hui-Ling Leong", "Jin-Jin Lim", "Gary Kum Hoe Kwok", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": "SG.01", "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/04me94w47"}, {"id": "https://openalex.org/I4210097409", "name": "SingHealth Duke-NUS Academic Medical Centre", "country": "SG", "collaborators": ["Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.2896699905395508, "longitude": 103.85006713867188}, "ror": "https://ror.org/00xcwps97"}, {"id": "https://openalex.org/I4210159875", "name": "Sengkang General Hospital", "country": "SG", "collaborators": ["Laura Tay", "Ee‐Ling Tay", "Shi‐Min Mah", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.3956650495529175, "longitude": 103.89337921142578}, "ror": "https://ror.org/05cqp3018"}, {"id": "https://openalex.org/I4210150261", "name": "National University Health System", "country": "SG", "collaborators": ["Sapphire Lin"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/05tjjsh18"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Si-Qi Lim", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}], "provenance": ["https://openalex.org/W4417304916", "https://pubmed.ncbi.nlm.nih.gov/41386281/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=105029688943&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=105029688943&origin=inward", "scopusDoi": "10.1016/j.jamda.2025.106027"}, {"id": "W4406370966", "title": "A valid and reliable 3D-printed electronic grip strength assessment tool", "year": 2025, "doi": "10.1016/j.jht.2024.11.010", "url": "https://doi.org/10.1016/j.jht.2024.11.010", "authors": ["Amelia A.

Single step tasks emulate a step-by-step gait pattern, an approach associated with knee pain when stair climbing. The objective of this study is to analyse the biomechanics and electromyography activity of both the leading and trailing limbs during single Step-up and Down tasks in knee osteoarthritis patients.\n\nMETHODS: Three-dimensional motion analysis captured biomechanical data of twenty participants with knee osteoarthritis (n = 20) and twenty four (n = 24) age matched controls completing isolated Step-Up and Step-Down tasks. Data was collected from both the leading and trailing limbs and analysed continuously using One-dimensional Statistical Parametric Mapping (α = 0.05).\n\nFINDINGS: During Step-Up, knee osteoarthritis participants demonstrated kinematic (p < 0.001), kinetic (p = 0.045), and electromyography (p < 0.001) variance compared to control participants, whilst Step-Down induced elevated external knee adduction moments (p = 0.042). Across both tasks, knee osteoarthritis participants stood with increased lower limb flexion in quiet standing and spent a proportionally elevated time in transitional double stance during Step-Up (p = 0.02).\n\nINTERPRETATION: Our study reveals that knee osteoarthritis patients display distinctive biomechanical strategies during single Step-Up and Down tasks, that deviate depending on whether the osteoarthritic knee is leading or trailing. Single-step tasks are a safer and practical alternative to other stair climbing tests. We hope that clinicians can use these findings to guide treatments that promote less effortful step and stair ambulation in knee osteoarthritis patients with advanced disease.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/39848097/", "type": "article", "institutions": [{"id": "https://openalex.org/I172675005", "name": "Nanyang Technological University", "country": "SG", "collaborators": ["Oliver Roberts", "Tsung-Lin Wu", "Phillis Soek Po Teng", "Yi Hu", "Bryan Yijia Tan"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02e7b5302"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Jun Liang Lau", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I148673510", "name": "Mandalay Technological University", "country": "MM", "collaborators": ["Yi Hu"], "geo": {"city": "Mandalay", "geonames_city_id": "1311874", "region": null, "country_code": "MM", "country": "Myanmar", "latitude": 21.972259521484375, "longitude": 96.18555450439453}, "ror": "https://ror.org/01gwmqw64"}], "provenance": ["https://openalex.org/W4406539802", "https://pubmed.ncbi.nlm.nih.gov/39848097/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85215550991&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85215550991&origin=inward", "scopusDoi": "10.1016/j.clinbiomech.2025.106436"}, {"id": "W4404581654", "title": "Biomechanical differences of Asian knee osteoarthritis patients during standing and walking using statistical parametric mapping: A cross-sectional study", "year": 2025, "doi": "10.1016/j.knee.2024.10.022", "url": "https://doi.org/10.1016/j.knee.2024.10.022", "authors": ["Yi Hu", "Phillis Soek Po Teng", "Tsung-Lin Wu", "Ross A.

We aim to determine gait biomechanical differences between healthy and KOA participants in an Asian population using One-dimensional Statistical Parametric Mapping (SPM1D) and explore if they are associated with standing joint angles.\n\nMETHODS: A total of 20 KOA and 24 healthy stood upright and walked 10 m at self-selected speeds. The standing angles, walking kinematic and kinetic parameters of the ankle, knee, hip and trunk were analysed. Lower limb muscle excitation was measured via electromyography. SPM1D was used to compare the healthy group with the KOA group, and for further subgroup analysis.\n\nRESULTS: The all KOA group had significantly greater standing knee flexion angles (KFA) (p < 0.001), standing ankle dorsiflexion angles (ADA) (p < 0.001), walking KFA during terminal stance (p = 0.001) and terminal swing (p = 0.02) and walking ADA during terminal stance (p = 0.02) and mid-swing to terminal swing (p = 0.001). Knee adduction moment (p = 0.04) and knee flexion moment (p = 0.03) were higher in severe KOA. A positive correlation was found between standing KFA and initial KFA (R 2 = 0.579), and mean walking KFA (R 2 = 0.801) in the KOA group.\n\nCONCLUSION: The increase in standing KFA was associated with an increase in walking KFA in the KOA group.

We compared this automated (LiDAR-based) standing-start 4-m gait speed test (AS-4MG) with automated and manual (stopwatch-based) dynamic-start 4-m gait speed tests (AD-4MG and MD-4MG, respectively) on between-method agreement, measurement repeatability, and predictive validity with functional outcomes.\n\nMETHODS: A sample of 48 community-dwelling adults (mean [SD], 69 [9] years) participated in this method comparison study. Participants completed a survey and a physical function assessment, from which self-reported stair difficulty, handgrip strength, sit-to-stand performance, and gait speed (AS-, AD-, and MD-4MG) were measured.\n\nRESULTS: Mean AS-4MG, AD-4MG, and MD-4MG were 1.12, 1.13, and 1.14 m/s, respectively, with a strong correlation (r = 0.94) and no systematic bias observed between AS-4MG and the referent AD-4MG. In the analyses of repeated gait measurements, coefficients of repeatability were <0.20 m/s for the automated tests (0.16 and 0.18 m/s for AS-4MG and AD-4MG, respectively) but not for MD-4MG (0.22 m/s).

Correlations for the automated tests were comparable, while AS-4MG correlations tended to exceed MD-4MG correlations.\n\nCONCLUSIONS: In community-dwelling adults, the AS-4MG test was unbiased when compared with the AD-4MG, encompassing a 9-m walkway, with both tests showing equivalence of measurement repeatability and predictive validity. The AS-4MG potentially allows gait measurements in confined spaces (e.g., doctor's office) where the gait speed test was previously unfeasible.

Thirty-five participants were included (82.9% [n=29] male; median [IQR]: age of 73.0 [11.0] years and disease duration of 4.0 [4.5] years).\n\nINTERVENTIONS: Not applicable.\n\nMAIN OUTCOME MEASURES: Participants were assessed with the FOG severity tool in a test-retest design, with time taken for each component recorded using a stopwatch during video-analysis. Validity of total FOG severity tool time, time taken to complete its turning and narrow-space components (i.e., time to navigate [TTN]), and an adjusted TTN were examined through correlations with validated FOG severity outcomes. To facilitate clinical interpretation, the TTN cut-off was determined using scatterplot smoothing regression, whereas minimal important change was calculated using predictive modeling.\n\nRESULTS: The FOG severity tool time, TTN, and adjusted TTN similarly demonstrated moderate correlations with the FOG questionnaire and percentage-FOG, and very high correlations with FOG severity tool-revised. The TTN was nonlinearly related to FOG severity, with a positive relationship observed in the first 300 seconds and plateauing after. minimal important change for TTN was 15.4 seconds reduction in timing (95% CI, 3.2-28.7).\n\nCONCLUSIONS: The TTN is a feasible, interpretable, and valid test of FOG severity. In busy clinical settings, TTN can provide a viable alternative when use of existing objective FOG measures is (often) unfeasible.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/39304078/", "type": "article", "institutions": [{"id": "https://openalex.org/I168639165", "name": "Singapore Institute of Technology", "country": "SG", "collaborators": ["Aileen Eugenia Scully", "Dawn Tan"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/01v2c2791"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Dawn Tan", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I205640436", "name": "Curtin University", "country": "AU", "collaborators": ["Beatriz de Oliveira"], "geo": {"city": "Perth", "geonames_city_id": "2063523", "region": "Western Australia", "country_code": "AU", "country": "Australia", "latitude": -31.95224, "longitude": 115.8614}, "ror": "https://ror.org/02n415q13"}, {"id": "https://openalex.org/I56590836", "name": "Monash University", "country": "AU", "collaborators": ["Keith Hill"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02bfwt286"}, {"id": "https://openalex.org/I4210126319", "name": "Duke-NUS Medical School", "country": "SG", "collaborators": ["Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02j1m6098"}], "provenance": ["https://openalex.org/W4402611745", "https://pubmed.ncbi.nlm.nih.gov/39304078/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85206141851&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85206141851&origin=inward", "scopusDoi": "10.1016/j.apmr.2024.09.003"}, {"id": "W4392167197", "title": "Associations between physical activity and development in preschool-aged children born <30 weeks’ gestation: a cohort study", "year": 2024, "doi": "10.1136/archdischild-2023-326045", "url": "https://doi.org/10.1136/archdischild-2023-326045", "authors": ["Tara L FitzGerald", "Kate L.

To measure PA, children wore an accelerometer and parents completed a diary for 7 days. Effects of PA on developmental outcomes, and associations between perinatal risk factors and PA, were estimated using linear regression.\n\nRESULTS: More accelerometer-measured PA was associated with better MABC-2 aiming and catching scores (average standard score increase per hour increase in PA: 0.54, 95% CI 0.11, 0.96; p=0.013), and lower WPPSI-IV processing speed index scores (average composite score decrease per hour increase in PA: -2.36, 95% CI -4.19 to -0.53; p=0.012). Higher accelerometer-measured PA was associated with better SDQ prosocial scores. Major brain injury in the neonatal period was associated with less moderate-vigorous and less unstructured PA at 4-5 years.\n\nCONCLUSIONS: Higher levels of PA are associated with aspects of motor, cognitive and social-emotional skill development in children 4-5 years old born <30 weeks.

We compared these tests on their predictive and clinical value concerning the risk of prefrailty/frailty and restricted life-space mobility (RLSM).\n\nDESIGN: Cross-sectional study.\n\nSETTING AND PARTICIPANTS: A sample of 1235 community-dwelling adults (mean ± SD, 68 ± 7 years) participated in this prospective cohort study.\n\nMETHODS: At baseline assessment, participants completed a survey and functional assessment, from which gait speed, sit-to-stand performance, self-reported mobility limitation, 40-item Frailty Index, and Life Space Assessment were measured. Participants with a 40-item Frailty Index >0.15 and a Life Space Assessment <60 points were classified as having prefrailty/frailty and RLSM, respectively. At 1-year follow-up assessment, prefrailty/frailty and RLSM were evaluated.\n\nRESULTS: Correlations between gait speed and sit-to-stand measures were high (ρ values >0.80). In multivariable ordinal models, these measures added incremental prognostic value beyond a base model comprising demographics and self-reported mobility limitation variables in predicting baseline and 1-year outcomes. Between 10mGS and 4mGS, models with 10mGS had higher concordance indices (differences, 0.005-0.009), and these differences translated to generally greater net benefit in decision curve analyses. Between 30sSTS and 5xSTS measures, no one measure consistently outperformed the other, with small net benefit differences between measures (<0.2%).\n\nCONCLUSIONS AND IMPLICATIONS: In community-dwelling older adults, gait speed and sit-to-stand measures meaningfully predicted prefrailty/frailty and RLSM. 10mGS provided more robust prognostic information than the 4mGS, whereas 5xSTS and 30sSTS measures showed near equivalence of performance.

HBR comprised at least five physical therapy sessions over 10 weeks.

The standardized assessment involves passive knee extension, in a position of 90° hip flexion. This creates passive insufficiency of the muscle and lacks ecological validity for walking, whereby the hip typically flexes to a maximum of 40° during swing phase, while the knee extends. This study compared assessment outcomes when completed in 40° and 90° hip flexion.\n\nMETHODS: The Modified Ashworth Scale and Modified Tardieu Scale, were performed on 35 adults with a neurological condition. Each participant was assessed by three assessors, resulting in 105 trials at 40° and 90°.\n\nRESULTS: There was a significant increase in the proportion of trials rated as spastic using the Modified Ashworth Scale ( p =.012, phi=.27), and Modified Tardieu Scale ( p <.001, phi=.36), and the severity of spasticity using the Modified Ashworth Scale ( p <.001, effect size (ES)=.50), and Modified Tardieu Scale ( p <.001 ES=.47), at 90° hip flexion. The angle of reaction occurred 32° earlier at 90° hip flexion ( p <.001, ES = 1.61).\n\nCONCLUSIONS: Completing hamstring assessments in 40° hip flexion may reduce the passive insufficiency and improve the ecological validity of assessment, for walking. This may assist in the selection of patients requiring intervention, when their goal relates to walking.\n\nThe position of the hip joint impacts hamstring spasticity assessment outcomes, regardless of the clinical outcome measure chosenThe application of bedside assessment methods in a manner reflective of functional tasks may assist in selecting individuals who require active spasticity interventionAs per international guidelines, the use of validated outcome measures in a goal directed and patient centered manner is required to maximize patient care.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/38100372/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Megan Banky", "Gavin Williams"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/01ej9dk98"}, {"id": "https://openalex.org/I2799990285", "name": "Epworth Hospital", "country": "AU", "collaborators": ["Megan Banky", "Gavin Williams"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02ett6548"}, {"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Benjamin F.

The International Classification of Functioning, Disability and Health (ICF) qualifiers scale has been used to subjectively assess arm movement abnormality, showing strong intra-rater and test-retest reliability, however, only moderate inter-rater reliability. This impacts clinical utility, limiting its use as a measurement tool. To both automate the analysis and overcome these errors, the primary aim of this study was to evaluate the ability of a novel two-level machine learning model to assess arm movement abnormality during walking in people with ABI.\n\nMETHODS: Frontal plane gait videos were used to train four networks with 50%, 75%, 90%, and 100% of participants (ABI: n = 42, healthy controls: n = 34) to automatically identify anatomical landmarks using DeepLabCut ™ and calculate two-dimensional kinematic joint angles. Assessment scores from three experienced neurorehabilitation clinicians were used with these joint angles to train random forest networks with nested cross-validation to predict assessor scores for all videos. Agreement between unseen participant (i.e. test group participants that were not used to train the model) predictions and each individual assessor's scores were compared using quadratic weighted kappa. One sample t-tests (to determine over/underprediction against clinician ratings) and one-way ANOVA (to determine differences between networks) were applied to the four networks.\n\nRESULTS: The machine learning predictions have similar agreement to experienced human assessors, with no statistically significant (p < 0.05) difference for any match contingency. There was no statistically significant difference between the predictions from the four networks (F = 0.119; p = 0.949). The four networks did however under-predict scores with small effect sizes (p range = 0.007 to 0.040; Cohen's d range = 0.156 to 0.217).\n\nCONCLUSIONS: This study demonstrated that machine learning can perform similarly to experienced clinicians when subjectively assessing arm movement abnormality in people with ABI. The relatively small sample size may have resulted in under-prediction of some scores, albeit with small effect sizes.

DESIGN: Single-center, participant- and assessor-blinded, comparative effectiveness randomized controlled trial. METHODS: Sixty-nine participants (31 females; 29 males; mean age: 46.5 years) with nonspecific chronic LBP were recruited for a 12-week program involving lumbar extension neuromuscular retraining in addition to resistance exercises (intervention) or 12 weeks of resistance exercises alone (control). The primary outcome measure was the Oswestry Disability Index. Secondary outcome measures included the Numeric Rating Scale, Tampa Scale for Kinesiophobia, Pain Self-Efficacy Questionnaire, and the International Physical Activity Questionnaire. Outcomes were measured at baseline, 6 weeks, and 12 weeks. RESULTS: Forty-three participants (22 control, 21 intervention) completed all outcome measures at 6 and 12 weeks. Fourteen participants were lost to follow-up, and 12 participants discontinued due to COVID-19 restrictions. Both groups demonstrated clinically important changes in disability, pain intensity, and kinesiophobia. The difference between groups with respect to disability was imprecise and not clinically meaningful (mean difference, -4.4; 95% CI: -10.2, 1.4) at 12 weeks. Differences in secondary outcomes at 6 or 12 weeks were also small with wide confidence intervals.

Ten videos were unique, while four were repeated. Freezing frequency, total duration, and percentage of time spent with freezing were computed. Reliability and variability were estimated using ICC (2,1) and mean absolute differences. Between-group differences were calculated with the one-way ANOVA.\n\nRESULTS: Inter- and intra-rater reliability ranged from moderate to good (ICC: inter-rater frequency = 0.63, duration = 0.78, percentage = 0.50; intra-rater frequency = 0.84, duration = 0.89, percentage = 0.50). Variability for freezing frequency was two episodes. Inter- and intra-rater variability for total freezing duration was 18.8 and 12.3 seconds, respectively.

Measures of lateropulsion, postural function, and weight-bearing asymmetry in standing were taken initially and fortnightly over eight weeks. Functional independence and walking abilities were assessed at six months post-stroke.\n\nRESULTS: Compared to individuals with moderate to severe lateropulsion, those with mild lateropulsion achieved higher levels of functional outcome at six months. However, there were a wide range of scores. Baseline lateropulsion severity explained 26% of the variation in functional outcome. A stronger correlation with functional outcome was observed for lateropulsion (-0.526) than function independence at baseline (0.384). For the task of standing with arm support, patterns of asymmetry were divergent at baseline, favouring either the paretic or non-paretic leg. Over the eight-week period, asymmetry moved towards the non-paretic leg and lateropulsion reduced consistently.\n\nCONCLUSIONS: Individuals with lateropulsion can recover from lateropulsion and make meaningful functional gains, including some individuals with more severe lateropulsion. Lateropulsion severity is a key indicator of functional outcome post-stroke.IMPLICATIONS FOR REHABILITATIONIndividuals with lateropulsion can make significant gains in terms of mobility and functional abilities by six months post-stroke, learning to compensate for their verticality impairment in standing by loading their non-paretic leg.It is important that stroke survivors with lateropulsion, including those with moderate and severe lateropulsion, are provided with adequate rehabilitation to optimise their longer-term mobility and functional abilities.Routine screening of acute stroke survivors for lateropulsion is recommended, given lateropulsion may negatively impact longer-term functional outcomes in stroke survivors.Therapists should carefully analyse the weight-bearing pattern which an individual with lateropulsion adopts in standing and subsequently tailor treatment to target this.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/37312557/", "type": "article", "institutions": [{"id": "https://openalex.org/I205640436", "name": "Curtin University", "country": "AU", "collaborators": ["Melissa Birnbaum", "Elissa Burton"], "geo": {"city": "Perth", "geonames_city_id": "2063523", "region": "Western Australia", "country_code": "AU", "country": "Australia", "latitude": -31.95224, "longitude": 115.8614}, "ror": "https://ror.org/02n415q13"}, {"id": "https://openalex.org/I4210087110", "name": "St Vincent's Hospital Melbourne", "country": "AU", "collaborators": ["Melissa Birnbaum", "Kim Brock"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/001kjn539"}, {"id": "https://openalex.org/I56590836", "name": "Monash University", "country": "AU", "collaborators": ["Keith Hill"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02bfwt286"}], "provenance": ["https://openalex.org/W4380576254", "https://pubmed.ncbi.nlm.nih.gov/37312557/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85161942625&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85161942625&origin=inward", "scopusDoi": "10.1080/09638288.2023.2222644"}, {"id": "W4388849679", "title": "Using item response theory to estimate interpretation threshold values for the Frailty Index in community dwelling older adults", "year": 2024, "doi": "10.1016/j.archger.2023.105280", "url": "https://doi.org/10.1016/j.archger.2023.105280", "authors": ["Yong‐Hao Pua", "Berend Terluin", "Laura Tay", "Ross A.

This study aimed to introduce and demonstrate the utility of an item response theory (IRT) method in estimating FI interpretation thresholds in community-dwelling adults and to compare them with cutoffs estimated using the receiver operating characteristics (ROC) method.\n\nMETHODS: A sample of 1,149 community-dwelling adults (mean[SD], 68[7] years) participated in this cross-sectional study. Participants completed a multi-domain geriatric screen from which the 40-item FI and 3 clinical anchors were computed - namely, (i)self-reported mobility limitations (SRML), (ii)\"fair\" or \"poor\" self-rated health (SRH), and (iii) restricted life-space mobility (RLSM). Participants were classified as having SRML-1 if they responded \"Yes\" to either of the 2 questions regarding walking and stair climbing difficulty and SRML-2 if they reported having walking and stair climbing difficulty. Participants with a Life Space Assessment score <60 points were classified as having RLSM. Threshold values for all anchor questions were estimated using the IRT method and ROC analysis with Youden criterion.\n\nRESULTS: The proportions of participants with SRML-1, SRML-2, Fair/Poor SRH, and RLSM were 21 %, 8 %, 22 %, and 9 %, respectively. The IRT-based thresholds for SRML-2 (0.26), fair/poor SRH (0.29), and RLSM (0.32) were significantly higher than those for SRML-1 (0.18). ROC-based FI cutoffs were significantly lower than IRT-based values for SRML-2, SRH, and RLSM (0.12 to 0.17), and they varied minimally and non-systematically across the anchors.\n\nCONCLUSIONS: The IRT method identifies biologically plausible FI thresholds that could meaningfully complement and contextualize existing thresholds for defining frailty.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/38000095/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Julian Thumboo", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I4210126319", "name": "Duke-NUS Medical School", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Julian Thumboo", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02j1m6098"}, {"id": "https://openalex.org/I4210108594", "name": "Amsterdam Neuroscience", "country": "NL", "collaborators": ["Berend Terluin"], "geo": {"city": "Amsterdam", "geonames_city_id": "2759794", "region": "North Holland", "country_code": "NL", "country": "The Netherlands", "latitude": 52.37403, "longitude": 4.88969}, "ror": "https://ror.org/01x2d9f70"}, {"id": "https://openalex.org/I4210151833", "name": "Amsterdam University Medical Centers", "country": "NL", "collaborators": ["Berend Terluin"], "geo": {"city": "Amsterdam", "geonames_city_id": "2759794", "region": "North Holland", "country_code": "NL", "country": "The Netherlands", "latitude": 52.37403, "longitude": 4.88969}, "ror": "https://ror.org/05grdyy37"}, {"id": "https://openalex.org/I865915315", "name": "Vrije Universiteit Amsterdam", "country": "NL", "collaborators": ["Berend Terluin"], "geo": {"city": "Amsterdam", "geonames_city_id": "2759794", "region": "North Holland", "country_code": "NL", "country": "The Netherlands", "latitude": 52.37403, "longitude": 4.88969}, "ror": "https://ror.org/008xxew50"}, {"id": "https://openalex.org/I4210159875", "name": "Sengkang General Hospital", "country": "SG", "collaborators": ["Laura Tay", "Ee‐Ling Tay", "Shi‐Min Mah", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.3956650495529175, "longitude": 103.89337921142578}, "ror": "https://ror.org/05cqp3018"}, {"id": "https://openalex.org/I157582758", "name": "SingHealth", "country": "SG", "collaborators": ["Julian Thumboo"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": "SG.01", "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/04me94w47"}, {"id": "https://openalex.org/I4210153592", "name": "Geriatric Education and Research Institute", "country": "SG", "collaborators": ["Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/04bqwt245"}], "provenance": ["https://openalex.org/W4388849679", "https://pubmed.ncbi.nlm.nih.gov/38000095/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85177858534&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://pure.amsterdamumc.nl/en/publications/cf6b127b-6692-44cf-9159-ba4a8eff0576", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85177858534&origin=inward", "scopusDoi": "10.1016/j.archger.2023.105280"}, {"id": "W4385659050", "title": "Validity and reliability of a new clinician-rated tool for freezing of gait severity", "year": 2024, "doi": "10.1080/09638288.2023.2242257", "url": "https://doi.org/10.1080/09638288.2023.2242257", "authors": ["Aileen Eugenia Scully", "Dawn Tan", "Beatriz de Oliveira", "Keith Hill", "Ross A.

This cross-sectional study investigated its validity and reliability.\n\nMETHODS: People with Parkinson's disease (PD) were recruited consecutively from clinics. Those who could not walk eight-metres independently (with or without an assistive device), comprehend instructions, or with co-morbidities affecting walking were excluded. Participants completed a set of assessments including the FOG Tool, Timed Up and Go (TUG), and Freezing of Gait Questionnaire. The FOG Tool was repeated and those reporting no medication state change evaluated for test-retest reliability. Validity and reliability were investigated through Spearman's correlations and ICC (two-way, random). McNemar's test was applied to compare the FOG Tool and TUG on the proportion of people with freezing.\n\nRESULTS: Thirty-nine participants were recruited [79.5%( n = 31) male; Median(IQR): age-73.0(9.0) years; disease duration-4.0(5.8) years]. Fifteen (38.5%) contributed to test-retest reliability analyses. The FOG Tool demonstrated strongest associations with the Freezing of Gait Questionnaire (ρ = 0.67, 95%CI 0.43-0.83). Test-retest reliability was excellent (ICC = 0.96, 95%CI 0.88-0.99). The FOG Tool had 6.2 times the odds (95%CI 2.4-20.4, p < 0.001) of triggering freezing compared to the TUG.\n\nCONCLUSIONS: The FOG Tool appeared adequately valid and reliable in this small sample of people with PD. It was more successful in triggering freezing than the TUG.\n\nThe Freezing of Gait Severity Tool’s assessment course is more effective than the commonly-used Timed Up and Go’s assessment course for eliciting freezing of gait for clinical evaluation in people with Parkinson’s disease.The Freezing of Gait Severity Tool can be considered for scoring freezing of gait severity in people with Parkinson’s disease in the clinical setting.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/37551868/", "type": "article", "institutions": [{"id": "https://openalex.org/I168639165", "name": "Singapore Institute of Technology", "country": "SG", "collaborators": ["Aileen Eugenia Scully", "Dawn Tan"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/01v2c2791"}, {"id": "https://openalex.org/I205640436", "name": "Curtin University", "country": "AU", "collaborators": ["Aileen Eugenia Scully", "Beatriz de Oliveira"], "geo": {"city": "Perth", "geonames_city_id": "2063523", "region": "Western Australia", "country_code": "AU", "country": "Australia", "latitude": -31.95224, "longitude": 115.8614}, "ror": "https://ror.org/02n415q13"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Dawn Tan", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I56590836", "name": "Monash University", "country": "AU", "collaborators": ["Keith Hill"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02bfwt286"}, {"id": "https://openalex.org/I4210126319", "name": "Duke-NUS Medical School", "country": "SG", "collaborators": ["Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02j1m6098"}], "provenance": ["https://openalex.org/W4385659050", "https://pubmed.ncbi.nlm.nih.gov/37551868/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85166943587&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://www.tandfonline.com/doi/pdf/10.1080/09638288.2023.2242257?needAccess=true&role=button", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85166943587&origin=inward", "scopusDoi": "10.1080/09638288.2023.2242257"}, {"id": "W4402369307", "title": "Vestibular Function and Postural Control in Children with Autism Spectrum Disorder", "year": 2024, "doi": "10.3390/jcm13175323", "url": "https://doi.org/10.3390/jcm13175323", "authors": ["Donella Chisari", "Jessica Vitkovic", "Ross A.

Methods: Ten children with a confirmed diagnosis of ASD according to DSM-V guidelines along with ten children with no known neurodevelopmental or motor delays participated in the study. Bruininks-Oseretsky Test of Motor Proficiency and the Paediatric Balance Scale measured functional balance ability, and postural sway was measured using static posturography with modified sensory inputs. Peripheral vestibular function was measured using cervical vestibular evoked myogenic potentials and video head impulse testing. Correlations between measures were performed. Results: When visual cues were removed, children with ASD demonstrated larger path velocities indicative of reduced postural control, and different patterns of postural sway. Functional balance was correlated with path velocities for conditions where sensory information was modified. No differences in peripheral vestibular function were noted between groups, and functional balance was not correlated with vestibular function. Conclusions: Findings suggest that while peripheral vestibular function is similar between groups, postural control differences in children with ASD remain, particularly for conditions where sensory information is modified.

For some of these children, concomitant vestibular deficits may impact postural control. This study aimed to explore vestibular function, functional balance and postural control, and the relationship between these measures in children with SNHL.\n\nDESIGN: Cross-sectional study quantifying peripheral vestibular function (vestibular evoked myogenic potentials [VEMP], video head impulse test), functional balance (Bruininks-Oseretsky Test of Motor Proficiency [BOT]) and postural control (static posturography with modified sensory inputs). The relationship between the degree of vestibular impairment, functional balance and postural control was explored.\n\nSTUDY SAMPLE: Eleven with SNHL, and 11 with normal sound detection (NSD) between 5 and 12 years of age.\n\nRESULTS: Children with SNHL had varying degrees of vestibular dysfunction and differences in overall balance performance.

However, it remains unclear which anthropometric variable is most strongly associated with handgrip strength. We aimed to, in older adults with no self-reported mobility limitations, determine whether height, weight, and body mass index (BMI) were meaningfully associated with handgrip strength.\n\nMETHODS: This cross-sectional study included community-dwelling ambulant participants, and we identified 775 older adults who reported no difficulty walking 100 m, climbing stairs, and rising from the chair. Handgrip strength was measured with a digital dynamometer. Bayesian linear regression was used to estimate the probabilities that the positive associations of height, weight, and BMI with handgrip strength exceeded 0 kg (the null value) and 2.5 kg (the clinically meaningful threshold value).\n\nRESULTS: Mean handgrip strength was 22.1 kg (SD, 4) for women and 32.9 kg (SD, 6) for men. Body height, weight, and BMI had >99.9% probabilities of a positive association with handgrip strength; however, the associations of per interquartile increase in body weight and BMI with handgrip strength had low probabilities (<5%) of exceeding the clinically meaningful threshold of 2.5 kg. In contrast, body height had the highest probability (99.6%) of a clinically meaningful association with handgrip strength: adjusting for age and gender, handgrip strength was 3.2 kg (95% CrI, 2.7 to 3.8) greater in older adults 1.61 m tall than in older adults 1.51 m tall.\n\nCONCLUSIONS: In a large sample of mobile-intact older adults, handgrip strength differed meaningfully by body height. Although requiring validation, our findings suggest that future efforts should be directed at normalizing handgrip strength by body height to better define subgroup-specific handgrip weakness.

Our study aimed to improve their clinical interpretability by examining trajectory curves across levels of self-reported walking and stair climbing function.\n\nDESIGN: A sample of 2624 patients with primary total knee arthroplasty participated in this retrospective longitudinal study. Monthly, for 4 mos after surgery, quadriceps strength and gait speed were quantified. At the month-6 time point, self-reported walking and stair climbing function was measured.\n\nRESULTS: All physical measures improved nonlinearly over time. In mixed-effects models, greater quadriceps strength and gait speed over time were associated with higher month-6 self-reported walking and stair climbing function ( P < 0.001). Steeper gains in quadriceps strength and gait speed were associated with higher levels of walking and stair-climbing function (interaction P < 0.001). Among female patients who had great difficulty with stair ascent and ambulation, quadriceps strength trajectory curves plateaued after 8 wks after total knee arthroplasty.\n\nCONCLUSIONS: By stratifying trajectory curves across clinically interpretable functional levels, our findings potentially provide patients and clinicians a means to better interpret the continuous-scaled quadriceps strength and gait speed values.

The V1 (slow) and V3 (fast) movements were completed as per standardised testing. Two additional assessments were completed, reflecting joint angular velocities during walking based on (i) a healthy control database (controlled velocity) and (ii) the individual's real-time joint angular velocities during walking (matched velocity). The agreement was compared using Cohen's and Weighted Kappa statistics, sensitivity and specificity.\n\nRESULTS: There was poor agreement when rating trials as spastic or not spastic at the ankle joint (Cohen's Kappa = 0.01-0.17). Trials were classified as spastic during V3 and not spastic during the controlled conditions in 81.6-85.1% of trials when compared to stance phase dorsiflexion angular velocities and 48.0-56.4% when compared to swing phase dorsiflexion angular velocities. The severity of muscle reaction demonstrated poor agreement at the ankle (Weighted Kappa = 0.01-0.28).

However, to perform a detailed assessment multiple devices are needed which can be time-consuming and costly to administer.\n\nPURPOSE: We designed and assessed the test-retest reliability of a 3D printed dexterity device in a cohort of healthy young adults and community-dwelling older adults. This study examines the reliability of the device, association between perceived fine motor gripping and manipulation dexterity components, and dominant hand outperformance during both tasks.\n\nSTUDY DESIGN: Test-retest study of a clinical measurement tool.\n\nMETHODS: A convenience sample of thirty-six healthy community-dwelling older and young adults was included in our study. The device was used to collect data at two testing sessions to establish test-retest reliability. Fine motor manipulation dexterity was assessed by lifting notched pegs over a vertical barrier and inserting them into randomly oriented holes sequentially. Fine motor gripping dexterity was assessed by taking these notched pegs out of the holes, lifting them over the barrier and dropping them into a large container.\n\nRESULTS: Intraclass correlation coefficient (ICC) 2,1 showed good to excellent test-retest reliability on the dominant and nondominant hands when using the device. Only modest association was found within-hand for the gripping versus manipulation dexterity tests. The between-hand motor gripping dexterity test demonstrated a strong association; however, between-hand the motor manipulation dexterity test was only moderately associated.\n\nCONCLUSION: The device was reliable, discriminated between the motor gripping and motor manipulating dexterity tasks, and was sensitive to handedness during the motor manipulating dexterity task.

This study proposes an alternative approach to computing the PFP by developing and validating a model that uses PFP components to predict the frailty index (FI) in community-dwelling older adults, without the need for predictor dichotomization.\n\nMETHODS: A sample of 998 community-dwelling older adults (mean [SD], 68 [7] years) participated in this prospective cohort study. Participants completed a multi-domain geriatric screen and a physical fitness assessment from which the count-based PFP and the 36-item FI were computed. One-year prospective falls and hospitalization rates were also measured. Bayesian beta regression analysis, allowing for nonlinear effects of the non-dichotomized PFP criterion predictors, was used to develop a model for FI (\"model-based PFP\"). Approximate leave-one-out (LOO) cross-validation was used to examine model overfitting.\n\nRESULTS: The model-based PFP showed good calibration with the FI, and it had better out-of-sample predictive performance than the count-based PFP (LOO-R 2 , 0.35 vs 0.22). In clinical terms, the improvement in prediction (i) translated to improved classification agreement with the FI (Cohen's k w , 0.47 vs 0.36) and (ii) resulted primarily in a 23% (95%CI, 18-28%) net increase in FI-defined \"prefrail/frail\" participants correctly classified. The model-based PFP showed stronger prognostic performance for predicting falls and hospitalization than did the count-based PFP.\n\nCONCLUSION: The developed model-based PFP predicted FI and clinical outcomes more strongly than did the count-based PFP in community-dwelling older adults.

Continuous discordance scores were quantified by the difference in percentiles between WOMAC and PPMs (WOMAC-PPM), where a positive discordance, WOMAC-PPM >0, implied greater perceived than observed disability.\n\nRESULTS: Around 1 in 4 patients had >20 percentile units in WOMAC-PPM discordance. In Bayesian regression analyses, knee pain intensity had >99% posterior probability of positive associations with WOMAC-PPM discordance. Among patients awaiting TKA, anxiety intensity had approximately 99% probability of positive associations with discordance, and these associations had >65% probability of exceeding 10 percentile units. In contrast, depression had low (79% to 88%) probability of any association with discordance.\n\nCONCLUSION: In patients who have knee OA, a sizable proportion reported substantially greater physical disability than actually observed. Pain and anxiety intensity, but not depression, were meaningful predictors of this discordance. If validated, our findings may help in refining patient selection criteria for TKA.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/36940758/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Juanita Low", "Ee-Lin Woon", "Seng-Jin Yeo", "Julian Thumboo"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I4210126319", "name": "Duke-NUS Medical School", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Julian Thumboo"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02j1m6098"}, {"id": "https://openalex.org/I172675005", "name": "Nanyang Technological University", "country": "SG", "collaborators": ["Bryan Yijia Tan"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02e7b5302"}, {"id": "https://openalex.org/I4210143268", "name": "Woodlands Health Campus", "country": "SG", "collaborators": ["Bryan Yijia Tan", "Chun-Yue Tan"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.4240649938583374, "longitude": 103.83736419677734}, "ror": "https://ror.org/03b489496"}, {"id": "https://openalex.org/I84392919", "name": "Temple University", "country": "US", "collaborators": ["Janet Prvu Bettger"], "geo": {"city": "Philadelphia", "geonames_city_id": "4560349", "region": "Pennsylvania", "country_code": "US", "country": "United States", "latitude": 39.95238, "longitude": -75.16362}, "ror": "https://ror.org/00kx1jb78"}, {"id": "https://openalex.org/I157582758", "name": "SingHealth", "country": "SG", "collaborators": ["Julian Thumboo"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": "SG.01", "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/04me94w47"}], "provenance": ["https://openalex.org/W4327919939", "https://pubmed.ncbi.nlm.nih.gov/36940758/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85152374095&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85152374095&origin=inward", "scopusDoi": "10.1016/j.arth.2023.03.044"}, {"id": "W4365518115", "title": "Estimating cutpoints of gait speed and sit-to-stand test values for self-reported mobility limitations in a cohort of community-dwelling older adults from Singapore: comparing receiver operating characteristic (ROC) analysis with adjusted predictive modelling", "year": 2023, "doi": "10.1016/j.archger.2023.105036", "url": "https://doi.org/10.1016/j.archger.2023.105036", "authors": ["Yong‐Hao Pua", "Laura Tay", "Berend Terluin", "Ross A.

Accumulating evidence, however, suggests that the adjusted predictive modeling (APM) method may be more appropriate to estimate these interpretational cutpoints. Thus, we aimed to compare, in community-dwelling older adults, gait speed and 5-STS cutpoints estimated using the ROC and APM methods.\n\nDESIGN: Cross-sectional study.\n\nSETTING AND PARTICIPANTS: This study analyzed data from 955 community-dwelling independently walking older adults (73%women) aged ≥60 years (mean, 68; range, 60-88).\n\nMETHODS: Participants completed the 10-metre gait speed and 5-STS tests. Participants were classified as having SRML if they responded \"Yes\" to either of the 2 questions regarding walking and stair climbing difficulty. Cutpoints for SRML and its component questions were estimated using ROC analysis with Youden criterion and the APM method.\n\nRESULTS: The proportions of participants with self-reported walking difficulty, self-reported stair climbing difficulty, and SRML were 10%, 19%, and 22%, respectively. Gait speed and 5-STS time were moderately correlated with each other (r=-0.56) and with the self-reported measures (absolute r-values, 0.39-0.44). ROC-based gait speed cutpoints were 0.14 to 0.16 m/s greater than APM-based cutpoints (P < 0.05) whilst ROC-based 5-STS time cutpoints were 0.8 to 3.3 s lower than APM-based cutpoints (P < 0.05 for walking difficulty). Compared with ROC-based cutpoints, APM-based cutptoints were more precise and they varied monotonically with self-reported walking difficulty, self-reported stair climbing difficulty, and SRML.\n\nCONCLUSIONS AND IMPLICATIONS: In a sample of 955 older adults, our findings of precise and biologically plausible gait speed and 5-STS cutpoints for SRML estimated using the APM method indicate that this promising method could potentially complement or even replace traditional ROC methods.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/37075584/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Julian Thumboo", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I4210126319", "name": "Duke-NUS Medical School", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Julian Thumboo", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02j1m6098"}, {"id": "https://openalex.org/I4210159875", "name": "Sengkang General Hospital", "country": "SG", "collaborators": ["Laura Tay", "Ee‐Ling Tay", "Shi‐Min Mah", "Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.3956650495529175, "longitude": 103.89337921142578}, "ror": "https://ror.org/05cqp3018"}, {"id": "https://openalex.org/I4210108594", "name": "Amsterdam Neuroscience", "country": "NL", "collaborators": ["Berend Terluin"], "geo": {"city": "Amsterdam", "geonames_city_id": "2759794", "region": "North Holland", "country_code": "NL", "country": "The Netherlands", "latitude": 52.37403, "longitude": 4.88969}, "ror": "https://ror.org/01x2d9f70"}, {"id": "https://openalex.org/I4210151833", "name": "Amsterdam University Medical Centers", "country": "NL", "collaborators": ["Berend Terluin"], "geo": {"city": "Amsterdam", "geonames_city_id": "2759794", "region": "North Holland", "country_code": "NL", "country": "The Netherlands", "latitude": 52.37403, "longitude": 4.88969}, "ror": "https://ror.org/05grdyy37"}, {"id": "https://openalex.org/I865915315", "name": "Vrije Universiteit Amsterdam", "country": "NL", "collaborators": ["Berend Terluin"], "geo": {"city": "Amsterdam", "geonames_city_id": "2759794", "region": "North Holland", "country_code": "NL", "country": "The Netherlands", "latitude": 52.37403, "longitude": 4.88969}, "ror": "https://ror.org/008xxew50"}, {"id": "https://openalex.org/I157582758", "name": "SingHealth", "country": "SG", "collaborators": ["Julian Thumboo"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": "SG.01", "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/04me94w47"}, {"id": "https://openalex.org/I4210153592", "name": "Geriatric Education and Research Institute", "country": "SG", "collaborators": ["Yee Sien Ng"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/04bqwt245"}], "provenance": ["https://openalex.org/W4365518115", "https://pubmed.ncbi.nlm.nih.gov/37075584/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85152460350&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://pure.amsterdamumc.nl/ws/files/172029483/Estimating-cutpoints-of-gait-speed-and-sit-to-stand-test-values-for-self-reported-mobility-limitations-in-a-cohort-of-co.pdf", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85152460350&origin=inward", "scopusDoi": "10.1016/j.archger.2023.105036"}, {"id": "W4388075573", "title": "Impaired Lumbar Extensor Force Control Is Associated with Increased Lifting Knee Velocity in People with Chronic Low-Back Pain", "year": 2023, "doi": "10.3390/s23218855", "url": "https://doi.org/10.3390/s23218855", "authors": ["Adrian Pranata", "Joshua Farragher", "Luke Perraton", "Doa El‐Ansary", "Ross A.

However, to our knowledge, there is a lack of evidence on objective physical activity assessment in Achilles tendinopathy. The purpose of this study is to (1) assess feasibility of using an inertial measurement unit (IMU) to monitor physical activity and IMU-derived biomechanical measures over 12-week treatment course by a physiotherapist; (2) conduct a preliminary analysis of changes in physical activity over 12-weeks.\n\nDESIGN: A feasibility prospective cohort study SETTING: A community setting.\n\nPARTICIPANTS: People with Achilles tendinopathy who had recently commenced (≤2 sessions), or were about to commence, treatment with a physiotherapist MAIN OUTCOME MEASURES: Participants wore a shank-mounted IMU on the affected side for one week at baseline, 6-, and 12-week follow-ups. The outcomes were pain/symptom severity, IMU-derived physical activity and biomechanical measures (stride rate, peak shank angular velocity, and peak shank acceleration).\n\nRESULTS: Thirty participants were recruited. There was a high retention rate (97%), response rate (97%), and IMU wear compliance at each timepoint (>93%). For pain/symptom severity, a significant time effect was observed between baseline and 12-week follow-up. Physical activity and IMU-derived biomechanical measures did not change over 12 weeks. Physical activity decreased at the 6-week follow-up but only returned to the baseline level at 12-week follow-up.\n\nCONCLUSIONS: A larger-scale cohort study assessing clinical outcomes and physical activity appears feasible. Preliminary data indicate that physical activity may not change significantly over 12-weeks in people undergoing physiotherapy management for Achilles tendinopathy.

Measures were: gait speed (6-metre walk), dynamic balance (step test), and quiet standing (Wii Balance Board). Centre of pressure speed, amplitude, standard deviation, root mean square, wavelet decomposition, and detrended fluctuation analysis were examined. Falls data were collected over a 12-month period post-discharge.\n\nRESULTS: Moderate strength correlations ( r = -0.505 to -0.548) with gait speed and step test scores were shown for 3/26 centre of pressure variables (mediolateral speed, low and moderate frequency wavelet). Twenty-two participants fell and the prediction was significant for gait speed and step test (IQR-odds ratio (OR) = 4.00 & 3.21) and 3/26 centre of pressure variables (mediolateral low-frequency wavelet: IQR-OR = 2.71; mediolateral detrended fluctuation analysis: IQR-OR = 3.06; anteroposterior detrended fluctuation analysis: IQR-OR = 2.71). Significant changes over time occurred for gait speed and step test scores and 20/26 centre of pressure variables.\n\nCONCLUSIONS: Standing centre of pressure variables have limited validity to reflect dynamic balance and falls risk after stroke. Frequency and complexity measures warrant further exploration.Implications for rehabilitationOur findings indicate that quiet standing centre of pressure variables have limited validity to reflect dynamic balance tasks and predict falls after stroke.The mediolateral and higher frequency variables may be more strongly recommended than the commonly used total centre of pressure speed measure.Measures of signal frequency and complexity may provide insight into postural control mechanisms and how these change over time following stroke.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/35382664/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kelly J.

Those with co-morbidities severely affecting gait were excluded. Participants were assessed with the FOG Severity Tool-Revised, three functional performance tests, the FOG Questionnaire, and outcomes measuring anxiety, cognition, and disability. The FOG Severity Tool-Revised was repeated for test-retest reliability. Exploratory factor analysis and Cronbach's alpha were computed for structural validity and internal consistency. Reliability and measurement error were estimated with ICC (two-way, random), standard error of measurement, and smallest detectable change (SDC 95 ). Criterion-related and construct validity were calculated with Spearman's correlations.\n\nRESULTS: Thirty-nine participants were enrolled [79.5% (n = 31) male; Median (IQR): age-73.0 (9.0) years; disease duration-4.0 (5.8) years], with fifteen (38.5%) who reported no medication state change contributing a second assessment for reliability estimation. The FOG Severity Tool-Revised demonstrated sufficient structural validity and internal consistency (α = 0.89-0.93), and adequate criterion-related validity compared to the FOG Questionnaire (ρ = 0.73, 95% CI 0.54-0.85).

To provide an easy-to-use clinical measure, this cross-sectional study explored if time to complete the recently-validated FOG Severity Tool (or its components) could be used to reflect FOG severity. Methods People with Parkinson’s disease who could independently ambulate eight-metres, understand instructions, and without co-morbidities severely affecting gait were consecutively recruited from outpatient clinics. Participants were assessed with the FOG Severity Tool in a test-retest design, with time taken for each component recorded using a stopwatch during video-analysis. Validity of total FOG Severity Tool time, time taken to complete its turning and narrow-space components (i.e., Time To Navigate, TTN), and an adjusted-TTN were examined through correlations with the FOG Questionnaire, percentage of time spent with FOG, and FOG Severity Tool-Revised score. To facilitate clinical interpretation, TTN cutoff was determined using scatterplot smoothing (LOESS) regression whilst minimal important change (MIC) was calculated using predictive modelling. Results Thirty-five participants were included [82.9%(n=29)male; Median(IQR): age – 73.0(11.0)years; disease duration – 4.0(4.5)years]. The FOG Severity Tool time, TTN, and adjusted-TTN similarly demonstrated moderate correlations with the FOG Questionnaire and percentage-FOG, and very-high correlations with FOG Severity Tool-Revised. TTN was nonlinearly related to FOG severity such that a positive relationship was observed in the first 300-seconds, beyond which the association plateaued. MIC for TTN was 15.4-seconds reduction in timing (95%CI 3.2 to 28.7). Conclusions The TTN is a feasible, interpretable, and valid test of FOG severity, demonstrating strong convergent validity with the FOG Severity Tool-Revised. In busy clinical settings, TTN provides a viable alternative when use of existing objective FOG measures is (often) unfeasible. Impact statement Busy clinicians need easy-to-use measures. In under 300-seconds, TTN test offers this for FOG severity, with a 15.4-seconds decrease in TTN time considered minimal improvement.", "abstractSource": "https://openalex.org/W4386030337", "type": "preprint", "institutions": [{"id": "https://openalex.org/I168639165", "name": "Singapore Institute of Technology", "country": "SG", "collaborators": ["Aileen Eugenia Scully", "Damien Meng Yew Tan", "Beatriz de Oliveira", "Keith Hill", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/01v2c2791"}, {"id": "https://openalex.org/I174025329", "name": "University of the Sunshine Coast", "country": "AU", "collaborators": ["Damien Meng Yew Tan", "Beatriz de Oliveira", "Keith Hill", "Yong‐Hao Pua"], "geo": {"city": "Sunshine Coast", "geonames_city_id": "10630449", "region": "Queensland", "country_code": "AU", "country": "Australia", "latitude": -26.65682, "longitude": 153.07955}, "ror": "https://ror.org/016gb9e15"}, {"id": "https://openalex.org/I205640436", "name": "Curtin University", "country": "AU", "collaborators": ["Damien Meng Yew Tan", "Beatriz de Oliveira", "Keith Hill", "Yong‐Hao Pua"], "geo": {"city": "Perth", "geonames_city_id": "2063523", "region": "Western Australia", "country_code": "AU", "country": "Australia", "latitude": -31.95224, "longitude": 115.8614}, "ror": "https://ror.org/02n415q13"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Damien Meng Yew Tan", "Beatriz de Oliveira", "Keith Hill", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I4210126319", "name": "Duke-NUS Medical School", "country": "SG", "collaborators": ["Damien Meng Yew Tan", "Beatriz de Oliveira", "Keith Hill", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02j1m6098"}, {"id": "https://openalex.org/I56590836", "name": "Monash University", "country": "AU", "collaborators": ["Damien Meng Yew Tan", "Beatriz de Oliveira", "Keith Hill", "Yong‐Hao Pua"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02bfwt286"}, {"id": "https://openalex.org/I4210113287", "name": "Parenting Research Centre", "country": "AU", "collaborators": ["Keith Hill"], "geo": {"city": "East Melbourne", "geonames_city_id": "6952201", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.80805587768555, "longitude": 144.97955322265625}, "ror": "https://ror.org/023teqr16"}], "provenance": ["https://openalex.org/W4386030337"], "identityEvidence": "Established rehabilitation coauthor", "openAccessUrl": "https://www.medrxiv.org/content/medrxiv/early/2023/08/20/2023.08.18.23294294.full.pdf"}, {"id": "W3126703688", "title": "Associations of the modified STarT back tool and Hospital Anxiety and Depression Scale (HADS) with gait speed and knee pain in knee osteoarthritis: a retrospective cohort study", "year": 2022, "doi": "10.1080/09638288.2021.1883750", "url": "https://doi.org/10.1080/09638288.2021.1883750", "authors": ["Cheryl Lian-Li Poon", "Philip Cheong", "John Wei-Ming Tan", "Julian Thumboo", "Ee-Lin Woon", "Ross A.

This study aimed to, in patients with knee osteoarthritis, (i) examine the convergent validity of mSBT with the Hospital Anxiety and Depression Scale (HADS) and (ii) compare the predictive validity of mSBT and HADS with gait speed and knee pain.\n\nMETHODS: We performed a retrospective cohort analysis of mSBT, HADS, gait speed, and knee pain outcomes data collected from 119 patients who received outpatient physical therapy. Of these patients who were evaluated at their first (baseline) physical therapy visit, 55 had available data at the Week-16 follow-up visit.\n\nRESULTS: mSBT and HADS showed moderately strong pairwise correlations (Spearman correlation > 0.57; p < 0.001). After adjusting for age, sex, body weight, and knee impairment variables in multivariable linear mixed-effects analyses, mSBT was associated with gait speed ( p < 0.001) and knee pain intensity ( p < 0.001) and it had comparable strength of association as HADS. In within-patient regression analyses, change in mSBT was associated with changes in gait speed ( p = 0.04) and knee pain ( p = 0.01) over 16 weeks.\n\nCONCLUSION: The mSBT had convergent validity with HADS and it showed predictive validity with gait speed and knee pain in knee osteoarthritis. Although broader validation is required, the 5-item mSBT psychosocial measure may be applied as part of routine clinical care to assess psychological distress in patients with knee osteoarthritis.IMPLICATIONS FOR REHABILITATIONThe 5-item psychosocial subscale of the modified STarT Back tool (mSBT) showed good convergent validity with the 14-item Hospital Anxiety and Depression Scale in patients with knee osteoarthritis.The mSBT psychosocial subscale showed predictive validity, at both cross-sectional and longitudinal levels, with gait speed and knee pain in patients with knee osteoarthritis.The mSBT can potentially be used in the busy clinical setting to assess psychological distress in patients with knee osteoarthritis.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/33577352/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Cheryl Lian-Li Poon", "Philip Cheong", "John Wei-Ming Tan", "Julian Thumboo", "Ee-Lin Woon", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I157582758", "name": "SingHealth", "country": "SG", "collaborators": ["Julian Thumboo"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": "SG.01", "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/04me94w47"}, {"id": "https://openalex.org/I4210126319", "name": "Duke-NUS Medical School", "country": "SG", "collaborators": ["Julian Thumboo", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/02j1m6098"}, {"id": "https://openalex.org/I4210113223", "name": "SingHealth Polyclinics", "country": "SG", "collaborators": ["Gary Cheok"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.282623052597046, "longitude": 103.81849670410156}, "ror": "https://ror.org/01ytv0571"}], "provenance": ["https://openalex.org/W3126703688", "https://pubmed.ncbi.nlm.nih.gov/33577352/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85100868671&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85100868671&origin=inward", "scopusDoi": "10.1080/09638288.2021.1883750"}, {"id": "W4306177022", "title": "Ballistic resistance training has a similar or better effect on mobility than non-ballistic exercise rehabilitation in people with a traumatic brain injury: a randomised trial", "year": 2022, "doi": "10.1016/j.jphys.2022.09.004", "url": "https://doi.org/10.1016/j.jphys.2022.09.004", "authors": ["Gavin Williams", "Leanne Hassett", "Ross A.

Does improved mobility translate to better health-related quality of life?\n\nDESIGN: A prospective, multicentre, randomised trial with concealed allocation, intention-to-treat analysis and blinded measurement.\n\nPARTICIPANTS: A total of 144 people with a neurological movement disorder affecting mobility as a result of traumatic brain injury.\n\nINTERVENTION: For 3 months, the experimental group had three 60-minute sessions of non-ballistic exercise rehabilitation per week replaced by ballistic resistance training. The control group had non-ballistic exercise rehabilitation of equivalent time. The non-ballistic exercise rehabilitation consisted of balance exercises, lower limb stretching, conventional strengthening exercises, cardiovascular fitness training and gait training.\n\nOUTCOME MEASURES: The primary outcome was mobility measured using the High-Level Mobility Assessment Tool (HiMAT). Secondary outcomes were walking speed, strength, balance and quality of life. They were measured at baseline (0 months), after completion of the 3-month intervention (3 months) and 3 months after cessation of intervention (6 months).\n\nRESULTS: After 3 months of ballistic resistance training, the experimental group scored 3 points (95% CI 0 to 6) higher on the 54-point HiMAT than the control group and remained 3 points (95% CI -1 to 6) higher at 6 months. Although there was a transient decrement in balance at 3 months in the experimental group, the interventions had similar effects on all secondary outcomes by 6 months. Participants with a baseline HiMAT < 27 gained greater benefit from ballistic training: 6 points (1 to 10) on the HiMAT.\n\nCONCLUSION: This randomised trial shows that ballistic resistance training has a similar or better effect on mobility than non-ballistic training in people with traumatic brain injury.

This study aimed to develop a clinician-rated tool for freezing of gait severity (i.e. Freezing of Gait Severity Tool), through determining clinicians' ratings of the most important triggering circumstances to be examined and aspects of freezing of gait to be measured.\n\nDESIGN: A three-round, web-based Delphi study.\n\nPARTICIPANTS: Healthcare professionals, with at least five years' experience in managing freezing of gait in people with Parkinson.\n\nMAIN OUTCOME MEASURES: Round 1 required participants ( n = 28) to rate items on a 5-point Likert scale, based on priority for inclusion in the Freezing of Gait Severity Tool. In Round 2, participants ( n = 18) ranked the items based on priority for inclusion. In Round 3, participants ( n = 18) confirmed or rejected the shortlisted items by judging their ability, on a binary scale, to screen for freezing of gait, detect changes in freezing severity, and discriminate between degrees of severity.\n\nRESULTS: Participants agreed with the triggering circumstances of turning hesitation, narrow space hesitation, start hesitation, cognitive dual-tasking, and open space hesitation should be assessed; and the aspects of gait freezing to be measured included freezing type, number of freezing episodes during a task, and average duration of freezing episodes.\n\nCONCLUSIONS: This study attained a consensus for the items to be included in a clinician-rated tool for freezing of gait severity.

We observed participants from 8 am till 5 pm every 10 minutes across two days and compared participant activity (physical, social and cognitive), location and people present pre and post-transition to new units. Built design, staffing levels and models of care were contrasted.Results We recruited 73 participants (63% stroke): old-ASU (n = 19); new-ASU (n = 15); old-IRU (n = 19); new-IRU (n = 20). Compared to old, new units had more single rooms, larger floor spaces and higher staffing levels. We found no significant change in participants’ activity levels between the old and new ASU. Participants in the new IRU showed increased physical activity (43.4% vs. 54.4%, p = 0.02) but social and cognitive activity remained similar. Participants were more alone (ASU 47.4% vs. 66.7%, p = 0.01; IRU 41.7% vs. 58.3%, p < 0.001), and less often with nursing staff (ASU 17.7% vs. 6.7%, p = 0.04; IRU 18.8% vs. 5.7%, p < 0.001) in new units.Conclusion Hospital design appears to impact on patients’ physical activity. Single rooms may increase isolation and reduce interaction with nursing staff.Implications for rehabilitationDesign of new rehabilitation units needs to consider patients’ social engagement with family, friends, other patients and staff in addition to privacy and infection control.A change in built design of rehabilitation units should prompt observation of patients’ activity levels and engagement with people and available space to ensure optimal use of new environments.Promotion of communal spaces and activities away from the bedroom to encourage social engagement is recommended for patients recovering in rehabilitation facilities.Less time in contact with nursing staff in rehabilitation environments with predominantly single rooms suggests a review of clinical practice and patient safety is warranted.", "abstractSource": "https://openalex.org/W3111820401", "type": "article", "institutions": [{"id": "https://openalex.org/I4210101259", "name": "Sunshine Coast University Hospital", "country": "AU", "collaborators": ["Ingrid Rosbergen", "I.

Participants were contacted via text message three times daily to rate their worst pain intensity. Physical activity and biomechanical measures derived from the IMU signals including daily number of steps, peak stride rate, peak shank acceleration, and peak shank angular velocity were calculated.\n\nRESULTS: The relationship between weekly worst pain and physical activity levels appeared modest; with increased steps not seeming to be linked to increased or reduced pain levels. According to the daily pain and daily IMU measures, a concordant pattern was evident in younger, highly active participants. However, in the middle-aged/older less active participants, there was either a fluctuation in pain intensity without fluctuation in the IMU measures, or a stable pattern of both pain and IMU measures.\n\nCONCLUSIONS: Our exploratory study results suggest that continuous monitoring of proxies of daily load measures in parallel with pain may provide information about load management strategies in people with Achilles tendinopathy.

The management of IAT commonly involves strengthening of the plantarflexors, although there is currently a paucity of research investigating plantarflexor neuromuscular performance specific to people with IAT.\n\nOBJECTIVES: To compare plantarflexor neuromuscular performance between men with IAT and controls, and to investigate the relationship between plantarflexor neuromuscular performance and patient reported outcome measures for men with IAT.\n\nDESIGN: Case control.\n\nMETHOD: 34 men with IAT (age 43.7 years [SD 10.02], weight 89.6 kg [16.3]) were matched with 34 healthy men (age 42.8 years [SD 8.9], weight 87.2 kg [9.7]). Participants underwent a plantarflexion maximal voluntary isometric contraction (MVIC) task, and a target force matching task. Neuromuscular variables from these tasks include; MVIC, rate of torque development (RTD), electromechanical delay (EMD), and muscle force steadiness. Participants also completed questionnaires regarding; pain and function, and psychological factors.\n\nRESULTS: The IAT group had reduced MVIC (p < 0.01) and RTD, (p < 0.01) compared to controls, however no significant difference in plantarflexor force steadiness (p = 0.08), or EMD (p = 0.71) was observed.

Clinical assessment included: upper and lower limb hypertonicity, spasticity and strength, balance, dynamic walking stability, arm and leg function, anxiety, arm pain/discomfort, and fear of falling.\n\nRESULTS: Significant, moderate-to-strong correlations ( r = 0.42-0.74, p < 0.05) existed between upper limb ARs and both hypertonicity and spasticity of the upper limb muscles and the knee extensors. Significant, moderate correlations to ARs ( r = 0.42-0.59, p < 0.05) existed for balance, dynamic stability, upper limb strength, and arm function. The severity of AR was significantly different between those with and without hypertonicity of the four tested upper limb muscles, elbow and long finger flexor spasticity, knee extensor spasticity, and reduced dynamic stability ( p < 0.05; effect sizes ≥0.80). However, these contributing factors were not present in all participants.\n\nCONCLUSIONS: Associated reactions are complex and multi-factorial.

Identifying older adults with functional performance \"below norms\" is the first step toward prevention. We aimed to (1) examine the associations of age, body height, and gender with gait speed and sit-to-stand performance and (2) develop subgroup-specific reference ranges in older adults with no self-reported mobility limitations.\n\nDESIGN: Cross-sectional study.\n\nSETTING AND PARTICIPANTS: This study analyzed data from 775 community-dwelling older adults who reported no difficulty walking 100 m, climbing stairs, and rising from the chair.\n\nMETHODS: Gait speed and sit-to-stand performance were measured by the 10-m gait speed test and 5-times sit-to-stand test, respectively. Bayesian linear regression was used to derive 95% reference ranges for gait speed and sit-to-stand performance, defined by different levels of age, body height, and gender.\n\nRESULTS: Overall, 95% reference range was 0.89-1.79 m/s for habitual gait speed and 7.4-27.9 stands/30 s for sit-to-stand pace. Age had the highest posterior probability (>99%) of a meaningful association with both functional outcomes. Additionally, height was strongly associated with gait speed: a 10-cm increase in height was associated with 0.07 m/s (95% credible interval, 0.05-0.10) faster gait speed. For sit-to-stand test, the lower 95% reference range limits tended to be similar across gender and gender-specific height subgroups, owing to the associations of faster sit-to-stand pace with shorter height and male gender. Because extensive tables of reference ranges are impractical, a web-based application (https://sghpt.shinyapps.io/ippts/) is created to provide subgroup-specific reference ranges.\n\nCONCLUSIONS AND IMPLICATIONS: In a large sample of mobile-intact older adults, reference ranges for gait speed and sit-to-stand performance differed meaningfully by age.

Participants completed a multi-domain geriatric screen and a physical fitness assessment, from which the 10-m habitual gait speed, GS%predicted, Physical Frailty Phenotype (PFP) index, and 36-item Frailty Index (FI) were computed.\n\nRESULTS: Based on the FI, ~49% of participants had pre-frailty or frailty. The optimal threshold of GS%predicted (0.93) had greater screening accuracy than the 1.0 m/s fixed threshold for gait speed (AUC, 0.65 vs. 0.60; DeLong's P < 0.001).

Our study aimed to (1) develop recovery curves with reference ranges, (2) identify the correlates of standard and constrained sit-to-stand weight-bearing symmetry, and (3) evaluate their predictive validity with gait speed.\n\nDESIGN: We performed a retrospective longitudinal study of 706 patients with primary unilateral total knee arthroplasty. Monthly, for 4 mos after surgery, sit-to-stand weight-bearing symmetry, knee pain, knee range of motion, quadriceps strength, and gait speed were quantified.\n\nRESULTS: Standard and constrained sit-to-stand weight-bearing symmetry measures improved nonlinearly over time. Standard sit-to-stand weight-bearing symmetry was most strongly associated with bilateral quadriceps strength, whereas constrained sit-to-stand weight-bearing symmetry was most strongly associated with ipsilateral quadriceps strength. Knee range of motion and contralateral knee pain were additional correlates. Both standard sit-to-stand and constrained sit-to-stand weight-bearing symmetry were independently and nonlinearly associated with gait speed in multivariable models.\n\nCONCLUSIONS: Our study provided recovery curves and validity data to support routine clinical measurement of sit-to-stand weight-bearing symmetry in total knee arthroplasty.

Observation of clinical practice however has highlighted an evidence-practice gap in the implementation of evidence-based strength training guidelines. Objective : To explore perceived barriers and facilitators that influence Australian physiotherapy practices when prescribing strength training with stroke survivors undergoing gait rehabilitation. Methods : Semi-structured interviews were conducted with a convenience sample of physiotherapists currently providing rehabilitation services to patients following stroke in Australia. Interviews were transcribed verbatim and line-by-line thematic analysis was undertaken to create themes and sub-themes. Results : Participants were 16 physiotherapists (12 females) with 3 months - 42 years experience working with people after stroke. Major themes identified were1) patient factors influence the approach to strength training; 2) interpretation and implementation of strength training principles is diverse; and 3) workplace context affects the treatment delivered. Physiotherapists displayed wide variation in their knowledge, interpretation and implementation of strength training principles and strength training exercise prescription was seldom evidence or guideline based. Workplace factors included the clinical preference of colleagues, and the need to modify practice to align with workforce resources. Conclusions : Implementation of strength training to improve walking after stroke was diverse. Therapist-related barriers to the implementation of effective strength training programs highlight the need for improved knowledge, training and research engagement. Limited resourcing demonstrates the need for organizational prioritization of stroke education and skill development. Narrowing the evidence-practice gap remains a challenge.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/33210574/", "type": "article", "institutions": [{"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Genevieve Tolé", "Anne E.

Quality assessment and data extraction were independently completed by 2 investigators. When similar outcome measures were used, standardized mean differences were calculated.\n\nEVIDENCE SYNTHESIS: A total of 19 randomized controlled trials with 633 participants (mean age, range 14-30 y) were included. Aquatic plyometric training was most commonly performed in waist to chest deep water (12/19 studies), 2 to 3 times per week for 6 to 12 weeks (18/19 studies), with final program foot contacts ranging from 120 to 550. Meta-analyses were not completed due to the clinical and statistical heterogeneity between studies. Compared with land plyometric training, aquatic plyometric training exercises and dosage were replicated (15/16 studies) and showed typically similar performance gains (3/4 knee extensor strength measures, 2/4 leg extensor strength measures, 3/4 knee flexor strength measures, 7/10 vertical jump measures, 3/3 sprint measures). In total, 2 of 3 studies monitoring muscle soreness reported significantly less soreness following training in water compared with on land. Compared with no active training (no exercise control group or passive stretching), most effect sizes demonstrated a mean improvement favoring aquatic plyometric training (23/32 measures). However, these were not significant for the majority of studies measuring isokinetic knee strength, vertical jump, and sprinting. The effect sizes for both studies assessing leg press strength indicated that aquatic plyometric training is significantly more effective than no training.\n\nCONCLUSION: Aquatic plyometric training appears similarly effective to land plyometric exercise for improving strength, jumping, and sprinting and may be indicated when joint impact loading needs to be minimized. However, the low quality of studies limits the strength of the conclusions.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/34564070/", "type": "review", "institutions": [], "provenance": ["https://openalex.org/W3203143230", "https://pubmed.ncbi.nlm.nih.gov/34564070/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85130989127&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85130989127&origin=inward", "scopusDoi": "10.1123/jsr.2020-0432"}, {"id": "W4309103227", "title": "The association between daily pain, physical activity, and biomechanical measures measured by wearable technology in people with Achilles tendinopathy", "year": 2022, "doi": "10.1016/j.jsams.2022.09.014", "url": "https://doi.org/10.1016/j.jsams.2022.09.014", "authors": ["Sanam Tavakkoli Oskouei", "Peter Malliaras", "K.

However, the quality of literature pertaining to these issues has yet to be collated and critiqued. This systematic review examined cross-sectional studies that objectively examined the ability of participants to open different medication packaging. Of the 8,692 studies identified, 12 met the inclusion criteria, all of which were direct observational studies given that prior research has identified a mismatch between self-report and actual ability. Scoring via the Appraisal Tool for Cross Sectional Studies revealed that the methodological quality of included studies was typically low. Study samples mostly consisted of older adults. All studies reported a non-negligible proportion of participants unable to open packaging, with the most difficulty associated with child-resistant containers. Several studies examined associations; however, no factor was consistently found to be significantly associated with the ability to open packaging. Despite these studies spanning >40 years, the packaging types examined remained largely the same. This suggests that, despite decades of research demonstrating that packaging is problematic, there has been a stagnation in medication packaging development. Whether this is attributed to a paucity of high-quality research, and therefore a lack of strong evidence that change is needed, is unclear. Future research should strive for better methodological quality, with generalisable cohorts assessed via observation in their home.

We examined if the Microsoft Kinect for Xbox One (Kinect) reliably (test-retest) and validly (concurrent) quantifies upper limb kinematics, and accurately classifies abnormalities (sensitivity/specificity), in an ABI cohort when compared to three-dimensional motion analysis (3DMA) and a subjective rating scale. We compared 42 adults with ABI to 36 healthy control (HC) participants. Walking trials were recorded by 3DMA and Kinect at self-selected (SSWS) and fast (FWS) walking speeds. When classifying abnormalities for 3DMA and Kinect, a 95% reference range (based on HC data) was calculated using the Kinematic Deviation Score worst axis (KDSw); values outside of this range were classified abnormal. Scores ≥ 2 in the subjective rating scale, based on International Classification of Functioning, Disability and Health Framework's Qualifiers Scale, were considered abnormal. Test-retest reliability and concurrent validity were determined using intra-class correlation coefficient (Absolute ICC 2,1 ) and Pearson's or Spearman's correlation respectively. Fisher's Exact Test was conducted to determine sensitivity and specificity between each combination of the two methods. Strong test-retest reliability was observed for 3DMA (median(IQR) ICC:0.86(0.85-0.90)). Kinect showed overall strong SSWS test-retest reliability (ICC:0.87(0.84-0.91)) and moderate FWS test-retest reliability (ICC:0.61(0.56-0.65)). Concurrent validity between 3DMA and Kinect was overall moderate. Sensitivity and specificity between 3DMA, Kinect and subjective scores were overall modest. Our results suggest caution should be used if implementing Kinect as its validity is modest against criterion-reference 3DMA; however, given its reliability and similar sensitivity/specificity to 3DMA further responsiveness research is warranted.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/34736087/", "type": "article", "institutions": [{"id": "https://openalex.org/I174025329", "name": "University of the Sunshine Coast", "country": "AU", "collaborators": ["Gabrielle L.

Case Description: This case series presents 4 patients scheduled for ND surgery who completed a comprehensive battery of balance and physical functioning assessments preoperatively and 6 weeks postoperatively. Outcomes: Post-ND surgery, the majority (n = 3) of patients reported increased upper-quadrant pain, with proprioception and neck range-of-motion measurements showing a decreasing trend. One patient had no neck pain or changes in proprioception. The changes for standing balance and endurance varied across the patients, with no observable trend. Discussion: Quality of life, physical activity, and a number of physical functioning measures, including proprioception and physical activity, were lower after ND surgery. This case series identifies the adverse effects of ND surgery performed prior to the start of adjuvant therapy, with many deficits noted potentially amenable to therapeutic intervention.

Assessment tool limitations may influence the conflicting evidence surrounding the relationship between spasticity and walking. This study investigated whether testing speeds and joint angles during a Modified Tardieu assessment matched lower-limb angular velocity and range of motion during walking.\n\nDESIGN: Observational study.\n\nSUBJECTS: Thirty-five adults with a neurological condition and 34 assessors.\n\nMETHODS: The Modified Tardieu Scale was completed. Joint angles and peak testing speed during V3 (fast) trials were compared with these variables during walking in healthy people, at 0.400.59, 0.600.79 and 1.401.60 m/s. The proportion of trials in which the testing speed, start angle, and angle of muscle reaction matched the relevant joint angles and angular velocity during walking were analysed.\n\nRESULTS: The Modified Tardieu Scale was completed faster than the angular velocities seen during walking in 88.7% (0.400.59 m/s), 78.9% (0.600.79 m/s) and 56.2% (1.401.60 m/s) of trials.

However, current technologies for accurately assessing ground reaction force are typically expensive.\n\nRESEARCH QUESTION: The aim of this study was to examine the validity and reliability of obtaining static and dynamic ground reaction force data from low-cost modified digital bathroom scales.\n\nMETHODS: Four modified bathroom scales, two units each of two different brands, were examined. Repeated mechanical loading trials were performed with known loads ranging from 0.01 to 65 kg, with acquired data compared against the known loading to calculate accuracy, hysteresis, and non-linearity. Dynamic trials consisting of 5 times sit-to-stand and weight-shifting were performed by 32 adults. Absolute and relative agreement intraclass correlation coefficient, and Pearson's and Spearman's correlations were performed to determine validity and reliability for the mechanical tests. Bland-Altmann plots were created for each comparison. Mean absolute error (MAE) and unbiased cross-correlation were performed on the dynamic data, comparing the calibrated data to the known values from a Bertec force platform.\n\nRESULTS: Hysteresis and non-linearity were excellent (<0.2 % full-scale), and mechanical test results showed excellent reliability and validity. Cross-correlation results for the dynamic data were excellent, however MAE for the more rapid sit-to-stand task was higher than the slower weight-shifting test. This may have been due to the low default sampling rate for the lowest noise setting of the HX711 amplifier (10 Hz).\n\nSIGNIFICANCE: In summary, our results suggest that digital bathroom scales can be easily and inexpensively modified to obtain accurate vertical ground reaction force data, with sensitivity to detect changes of as little as 0.01 kg.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/33321409/", "type": "article", "institutions": [{"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Benjamin F.

This study aimed to (1) compare neurodevelopmental, respiratory health and brain magnetic resonance imaging (MRI) outcomes between children born MLP and term at 9 years of age; (2) examine the differences in brain growth trajectory from infancy to 9 years between children born MLP and term; and in children born MLP; (3) examine the relationship between brain development and neurodevelopment at 9 years; and (4) identify risk factors for poorer outcomes at 9 years.\n\nMETHODS AND ANALYSIS: The \"LaPrem\" ( La te Pre term M RI Study) study is a longitudinal cohort study of children born MLP and term controls, born at the Royal Women's Hospital in Melbourne, Australia, between 2010 and 2013. Participants were recruited in the neonatal period and were previously followed up at 2 and 5 years. This 9-year school-age follow-up includes neuropsychology, motor and physical activities, and lung function assessments, as well as brain MRI. Outcomes at 9 years will be compared between birth groups using linear and logistic regressions. Trajectories of brain development will be compared between birth groups using mixed effects models. The relationships between MRI and neurodevelopmental outcomes, as well as other early predictors of poor 9-year outcomes, will be explored using linear and logistic regression.\n\nETHICS AND DISSEMINATION: This study was approved by the human research ethics committee at the Royal Children's Hospital, Melbourne, Australia.

This chapter provides a pragmatic guide to low-cost software, hardware, and developer kits for those interested in exploring wearables in clinical populations. Firstly, the build, repurpose or outsource decision process is described. Secondly, key hardware and software design decisions are described to simplify the choice.

Approximately 50% of people with PD experience freezing of gait, a motor symptom associated with falls, disability, and poorer quality of life. Accurate assessment of freezing of gait severity is important for guiding management. The aim of this systematic review was to determine the measurement properties of subjective and objective clinical assessments of freezing of gait severity using the COSMIN methodology to facilitate better outcome measure selection.\n\nMETHODS: Three databases (MEDLINE, EMBASE, and CINAHL) were searched. The COSMIN Risk of Bias checklist was used for evaluating quality of included studies. Data on measurement properties were extracted. Where possible, meta-analysis was performed.\n\nRESULTS: Nineteen studies investigating measurement properties of 7 outcome measures (patient-reported outcome measures, n = 3; objective assessment tools, n = 4) were included. Ten studies evaluated the Freezing of Gait Questionnaire. Based on COSMIN criteria, the best performing outcome measures were the Freezing of Gait Questionnaire and the Dynamic Parkinson Gait Scale. Both outcome measures demonstrated sufficient structural validity, internal consistency, reliability, construct validity, and responsiveness. The Freezing of Gait Questionnaire was supported with mostly moderate to high quality of evidence, but the evidence for the Dynamic Parkinson Gait Scale was of low quality due to inadequate sample size.\n\nCONCLUSIONS: Content validity and measurement invariance remain unknown for all outcome measures. The Freezing of Gait Questionnaire is the best measure currently available. Further external validation and reliability studies would strengthen the evidence to support the use of the Dynamic Parkinson Gait Scale.\n\nIMPACT: Awareness of limitations of outcome measures facilitates better selection. Without evidence for content validity and measurement invariance, clinicians should consider if their chosen test accurately measures freezing of gait severity and whether it can be applied in populations different to the original study's population.\n\nLAY SUMMARY: Accurately assessing freezing of gait severity is important for guiding management of this disabling symptom.

The modifiable factors associated with poststroke physical activity levels need to be identified to develop targeted interventions.\n\nOBJECTIVE: The objective of this study was to investigate the factors at discharge from inpatient rehabilitation that are associated with physical activity levels at 3 months following discharge.\n\nDESIGN: This was a prospective cohort study.\n\nMETHODS: Sixty-four people with stroke completed baseline assessments at discharge from inpatient rehabilitation and 55 completed the follow-up 3 months later. The candidate factors (ie, gait speed, balance, strength, cognition, mood, and motivation) were measured at discharge. The primary outcome measure at follow-up was walking-related activity (measured by wrist-worn accelerometer). Secondary outcome measures were physical activity participation (Activity Card Sort) and intensity of physical activity (International Physical Activity Questionnaire-Short 7 days). Adjusted separate multivariable linear regression models or proportional odds regression models were used to evaluate the associations between candidate factors and physical activity.\n\nRESULTS: Gait speed and balance were associated with all aspects of physical activity. Higher level of intrinsic motivation was also associated with higher physical activity participation. Anxiety demonstrated a significant nonlinear relationship with physical activity participation.\n\nLIMITATIONS: Inclusion of fatigue and individual muscle strength could have provided further insights into associations with steps per day.\n\nCONCLUSION: The results demonstrated that better physical function at discharge from inpatient rehabilitation was associated with future increased levels of physical activity. Additionally, higher levels of motivation impacted on increased physical activity participation. The influence of anxiety on physical activity participation requires further exploration. Mixed-method study designs can be utilized to further understand the factors associated with poststroke physical activity.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/31995190/", "type": "article", "institutions": [{"id": "https://openalex.org/I174025329", "name": "University of the Sunshine Coast", "country": "AU", "collaborators": ["Shamala Thilarajah"], "geo": {"city": "Sunshine Coast", "geonames_city_id": "10630449", "region": "Queensland", "country_code": "AU", "country": "Australia", "latitude": -26.65682, "longitude": 153.07955}, "ror": "https://ror.org/016gb9e15"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Shamala Thilarajah", "Yong‐Hao Pua", "Dawn Tan", "Ashfaq Larik", "Chek-Wai Bok"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kelly J.

The ST assesses a person's ability to place their paretic (paretic ST) or nonparetic (nonparetic ST) foot rapidly and repeatedly on and off a standardized block while standing. No study has formally explored if the 2 tests are interchangeable. Our study aimed to: (1) differentiate the correlates of paretic and nonparetic ST, and (2) compare their associations with physical function and falls.\n\nMETHODS: Eighty-one survivors of stroke were consecutively recruited from inpatient rehabilitation units (n = 4) and were assessed within 1 week prior to discharge. In addition to the ST, a handheld dynamometer and computerized posturography were used to measure lower limb muscle strength and standing balance, respectively. Self-selected gait speed and Timed Up and Go test were also assessed as measures of physical function. Falls data were monitored for 12 months post discharge using monthly calendars. Multivariable regression analyses were used to differentiate (1) the correlates of paretic and nonparetic STs, and (2) their associations with physical function and falls.\n\nRESULTS: The median score for the paretic and nonparetic STs were 8 and 9 steps, respectively. Paretic ankle plantar-flexor and dorsiflexor strength were the strongest correlates of nonparetic ST, whereas both paretic ankle and knee extensor strength were the strongest correlates of paretic ST. In multivariable analyses adjusting for each other, both STs were independently associated with gait speed and Timed Up and Go scores. Paretic ST (odds ratio = 0.37; 95% CI = 0.22 to 0.62) was a stronger predictor than nonparetic ST (odds ratio = 0.51; 95% CI = 0.34 to 0.78) in predicting future falls.\n\nCONCLUSION: This study confirmed that the paretic and nonparetic STs are noninterchangeable. ST scores should be assessed separately to achieve a more complete interpretation.\n\nIMPACT: To our knowledge, this study is the first to objectively evaluate the similarities and differences between paretic and nonparetic STs. This information may refine the use and interpretation of the 2 STs for survivors of stroke.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/33587141/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Shamala Thilarajah", "Dawn Tan", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kelly J.

In this preliminary study, overall model fit and individual item and person fit were found to be good using fit residual statistics and chi-square probability values. The BLS was found to be unidimensional and have good internal consistency (Person Separation Index 0.867). Thresholds for four of the five items were found to be only marginally disordered and were subsequently not modified. Non-uniform differential item functioning was detected for age for the transfers item; however, this item did not display item misfit and was therefore not removed.\n\nCONCLUSIONS: This study identified good psychometric properties of the BLS using Rasch analysis and supports the use of the BLS as a measure of lateropulsion following stroke.

Twenty-five people participated in this crossover design study, performing 50 min of VR gaming either continuously or with intermittent 10 min exposure/rest intervals. Standing eyes open, two-legged balance assessments were performed immediately pre-, immediately post- and 40 min post-exposure. The primary outcome measure was total path length; secondary measures included independent axis path velocity, amplitude, standard deviation, discrete and continuous wavelet transform-derived variables, and detrended fluctuation analysis. Total path length was significantly ( p < 0.05) reduced immediately post-VR gaming exposure in the intermittent rest break group both in comparison to within-condition baseline values and between-condition timepoint results. Conversely, it remained consistent across timepoints in the continuous exposure group.

The aim of this study was to compare muscle strength, motor skills, and physical activity (PA) of preschool-aged children born <30 weeks with those born at term.\n\nMETHODS: In this cohort study, 123 children born <30 weeks and 128 born at term were assessed. Children were aged ≥4 years, 0 months and <6 years, 0 months' corrected age at the time of the assessment. Outcomes included grip strength (kg), Movement Assessment Battery for Children 2nd edition (MABC-2), Little Developmental Coordination Disorder Questionnaire, accelerometer-measured PA, and a parent-completed PA diary. Linear regression and mixed effects models were used to examine differences between children born <30 weeks and those born at term.\n\nRESULTS: Children born <30 weeks had poorer grip strength (preferred hand; mean difference [95% CI] -0.60 kg [-1.04 to -0.15]) and poorer motor competence (Movement Assessment Battery for Children 2nd edition standard score mean difference -2.17 [-3.07 to -1.27]; Little Developmental Coordination Disorder Questionnaire total score mean difference -5.5 [-9.2 to -2.8]) than term-born children. Children born <30 weeks also completed fewer minutes of accelerometer-measured PA (mean difference -41 minutes [-62 to -20]), more minutes of accelerometer-measured stationary behavior (mean difference 33 minutes [12 to 54]), and more minutes of parent-reported screen time (mean difference 21 minutes [10 to 32]) per day.\n\nCONCLUSION: Preschool-aged children born <30 weeks had poorer muscle strength, motor skills, and PA levels than term-born children. These findings suggest that preschool-aged children born <30 weeks may benefit from enhanced surveillance and PA promotion to improve life-long health outcomes.\n\nIMPACT: In our study, children born <30 weeks had reduced muscle strength and poorer motor skills, participated in less PA, and had more stationary and screen behavior than term-born children. These findings emphasize that awareness of multidomain motor deficits in children born <30 weeks' gestation is needed in clinical practice. Given the associations between higher PA and health benefits and the recognition that PA levels can track from early childhood into adulthood, our study highlights the need for assessment and promotion of PA in preschool-aged children born <30 weeks' gestation. Lay Summary. Preschool-aged children born <30 weeks' gestation have poorer strength, motor skills, and physical activity behaviors than their term-born peers. Clinicians and early childhood educators should recognize that the preschool period is a critical time for the assessment and promotion of PA in children born <30 weeks.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/33517456/", "type": "article", "institutions": [{"id": "https://openalex.org/I1321649718", "name": "Royal Children's Hospital", "country": "AU", "collaborators": ["Tara L FitzGerald", "Kate L.

Design Cross-sectional observational study. Setting A major brain injury rehabilitation centre in Australia. Participants Forty-one participants with an ABI and hemiplegic upper limb AR during walking. Interventions N/A. Main Outcome Measures Participants underwent 3DMA at their self-selected walking speed to generate an AR outcome measure, quantifying upper limb kinematic deviation compared to healthy controls at each joint axis and whole upper limb. Three experienced neurological physiotherapists viewed video recordings of the participants’ walking trials and applied the ICF Qualifiers Scale to subjectively rate the global AR severity and severity at each upper limb joint on a 5-point scale. The comparative accuracy was calculated via quantifying relationships (Fisher's exact test), percentage agreement, sensitivity, and specificity. Results The ICF Qualifiers Scale had limited accuracy compared to 3DMA hemiplegic upper limb assessment. The wrist severity score was the only outcome demonstrating a significant relationship to the corresponding 3DMA outcome (p 0.80) for four of the seven outcomes. Conclusions Given that the ICF Qualifiers scale tended to under classify abnormality with false negatives likely, it cannot be confidently implemented in clinical practice. There appears to be a disconnect between 3DMA and subjective rating of ARs. Evaluation of ARs during walking may require objective assessment.

Associated reaction measurements included biceps brachii sEMG, elbow goniometry, and three-dimensional motion analysis kinematics during walking. Pearson correlations evaluated the relationships between seated and dynamic walking AR tests and between muscle activity and kinematic measures. Chronic participants were reassessed 1 wk later for reliability.\n\nRESULTS: A strong (r = 0.65) and moderate (r = 0.53) relationship existed for biceps brachii sEMG during seated and walking tests at self-selected and fast walk, respectively. A weak to moderate relationship existed between biceps brachii sEMG and kinematics during walking and between seated and walking measures of ARs (r = 0.23-0.53). All tests had strong to very strong test-retest reliability (intraclass correlation coefficients, >0.78).\n\nCONCLUSION: Seated contralateral maximal voluntary isometric contraction tests correlate only weakly to moderately with AR walking kinematics and moderately to strongly with biceps brachii activation during walking.

However, clinical adoption is relatively slow, and the factors affecting use remain underexplored. This study aimed to investigate factors influencing technology use by clinicians working in neurorehabilitation.\n\nMETHODS: In this qualitative study, 9 physical therapists and 9 occupational therapists (N = 18) were recruited from urban and regional locations in Australia and in Singapore. Three 60-minute focus groups were conducted via video conferencing. Each group comprised 3 physical therapists and 3 occupational therapists working across different neurorehabilitation settings. Participants were asked to discuss which technologies they used in their workplace for physical assessment and treatment and barriers, motivators, and future desires for technology use. Transcripts were analyzed independently using an inductive approach to generate codes and themes.\n\nRESULTS: Our results comprised 3 themes and 7 categories. These were encompassed by a single overarching theme, namely \"Technology use is influenced by the benefits and challenges of the technology itself, users, and organizational context.\" Themes showed that technology should promote effective interventions, is preferred if easy to use, and should be dependable. Furthermore, clinical reasoning is important, and users have varying levels of receptivity and confidence in technology use. Also, organizational resources are required, along with supportive cultures and processes, to facilitate technology use.\n\nCONCLUSIONS: The themes identified multiple and interlinking factors influencing clinicians' use of technology in neurorehabilitation settings. Clinicians often consider context-specific benefits and challenges when deciding whether to use technology. Although our study found that clinicians generally perceived technology as having a beneficial role in improving health outcomes, there were several challenges raised. Therefore, the characteristics of the technology itself, individual users, and organizational context should be considered.\n\nIMPACT: These findings will guide successful technology implementation and future developments.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/33522582/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kelly J.

Originally developed as a measure of lower-limb strength, the five times sit-to-stand test has shown associations with other measures of impairment, such as balance ability. We aimed to compare strength and balance in their relationship with the five times sit-to-stand test following stroke.\n\nMETHODS: Sixty-one participants following stroke were recruited from two hospitals in this cross-sectional observational study. Participants underwent assessment of the five times sit-to-stand (measured with a stopwatch), bilateral lower-limb muscle strength of seven individual muscle groups (hand-held dynamometry), and standing balance (computerised posturography). Partial correlations (controlling for body mass and height) were used to examine bivariate associations. Regression models with partial F-tests (including pertinent covariates) compared the contribution of strength (both limbs) and balance to five times sit-to-stand time.\n\nRESULTS: The strength of the majority of lower-limb muscle groups (6/7) on the paretic side had a significant (P < 0.05) partial correlation with five times sit-to-stand time (r = -0.34 to -0.47) as did all balance measures (r = -0.27 to -0.56). In our regression models, knee extensor strength, total path length, and anteroposterior path velocity provided the largest contribution to five times sit-to-stand over covariates amongst strength and balance measures (R 2 = 16.6 to 17.9 %). Partial F-tests revealed that both lower-limb strength and balance contribute to five times sit-to-stand time independent of each other. A regression model containing knee extensor strength and anteroposterior path velocity accounted for 25.5 % of the variance in five times sit-to-stand time over covariates.\n\nCONCLUSIONS: The strength of the knee extensor muscle group along with measures of standing balance ability (total path length and anteroposterior path velocity) both independently contribute to five times sit-to-stand time.

However, existing healthy-subjects studies have been equivocal in demonstrating KAM reduction with valgus knee bracing.\n\nRESEARCH QUESTION: What are the immediate effects of valgus bracing at different tension levels on KAM during walking at a controlled speed and does body height modify the brace-KAM associations?\n\nMETHODS: Data from 32 knee-healthy participants were analysed in this randomized crossover trial. Participants performed walking trials at controlled speed (1.3 ± 0.065 m/s) both with and without an Ossür Unloader One® brace. During the bracing condition, valgus tension was incrementally increased, from zero tension to normal tension and to maximum tolerable tension.\n\nRESULTS: Valgus bracing minimally increased knee flexion at heel-strike (P < 0.001) in a dose-dependent manner and minimally reduced gait velocity (∼0.015m/s) across all tension levels. Valgus bracing, overall, did not significantly reduce the various KAM measures. However, brace use at maximal tension was associated with a 0.04Nm/kg (9.2 %) increase in first peak KAM amongst participants with a body height of 1.75 m and a 0.03Nm/kg (7.6 %) decrease in first peak KAM amongst participants with a body height of 1.55 m.\n\nSIGNIFICANCE: Valgus bracing did not reduce the various KAM measures during walking; however, body height may play a moderating role. Given knee brace sizes vary more in circumference than length, this result may be due to the ratio between effective moment arm length relative to limb length.

This study aimed to use machine learning methods to predict post-total knee arthroplasty (TKA) walking limitation, and to compare their performance with that of logistic regression.\n\nMETHODS: From the department's clinical registry, a cohort of 4026 patients who underwent elective, primary TKA between July 2013 and July 2017 was identified. Candidate predictors included demographics and preoperative clinical, psychosocial, and outcome measures. The primary outcome was severe walking limitation at 6 months post-TKA, defined as a maximum walk time ≤ 15 min. Eight common regression (logistic, penalized logistic, and ordinal logistic with natural splines) and ensemble machine learning (random forest, extreme gradient boosting, and SuperLearner) methods were implemented to predict the probability of severe walking limitation. Models were compared on discrimination and calibration metrics.\n\nRESULTS: At 6 months post-TKA, 13% of patients had severe walking limitation. Machine learning and logistic regression models performed moderately [mean area under the ROC curves (AUC) 0.73-0.75]. Overall, the ordinal logistic regression model performed best while the SuperLearner performed best among machine learning methods, with negligible differences between them (Brier score difference, < 0.001; 95% CI [- 0.0025, 0.002]).\n\nCONCLUSIONS: When predicting post-TKA physical function, several machine learning methods did not outperform logistic regression-in particular, ordinal logistic regression that does not assume linearity in its predictors.\n\nLEVEL OF EVIDENCE: Prognostic level II.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/31832697/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Julian Thumboo", "Eleanor Shu-Xian Chew", "Cheryl Lian-Li Poon", "Seng-Jin Yeo"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I901861585", "name": "Vanderbilt University Medical Center", "country": "US", "collaborators": ["Hakmook Kang"], "geo": {"city": "Nashville", "geonames_city_id": "4644585", "region": "Tennessee", "country_code": "US", "country": "United States", "latitude": 36.16589, "longitude": -86.78444}, "ror": "https://ror.org/05dq2gs74"}, {"id": "https://openalex.org/I2802225915", "name": "Changi General Hospital", "country": "SG", "collaborators": ["Hwei‐Chi Chong"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.2896699905395508, "longitude": 103.85006713867188}, "ror": "https://ror.org/02q854y08"}], "provenance": ["https://openalex.org/W2996309850", "https://pubmed.ncbi.nlm.nih.gov/31832697/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85076596153&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85076596153&origin=inward", "scopusDoi": "10.1007/s00167-019-05822-7"}, {"id": "W3048916847", "title": "Quantification of abnormal upper limb movement during walking in people with acquired brain injury", "year": 2020, "doi": "10.1016/j.gaitpost.2020.08.110", "url": "https://doi.org/10.1016/j.gaitpost.2020.08.110", "authors": ["Michelle Kahn", "Gavin Williams", "Benjamin F.

Three-dimensional motion analysis (3DMA) can quantify upper limb abnormality kinematically, with composite scores condensing multiple joint axes data into a single score.\n\nRESEARCH QUESTION: Are 3DMA-derived composite scores valid (known-groups and convergent validity), reliable and able to quantify speed-related changes in abnormal upper limb movement during walking?\n\nMETHODS: This observational study compared 42 adults with ABI and abnormal upper limb movements during walking with 36 healthy controls (HC) at a matched walking speed intention. Participants underwent 3DMA assessment of self-selected and fast walking speeds. Composite scores quantified the affected upper limb's kinematic abnormality. The Arm Posture Score arithmetic mean version (APSam) and 1.96 standard deviation reference-range scaled versions; the Kinematic Deviation Score mean (KDSm) and worst score (KDSw) were evaluated for association with each other and subjective abnormality rating (Pearson's 'r' correlation), test-retest reliability (intra-class correlation coefficient (ICC)), and ability to quantify speed-related changes in abnormal upper limb movement (Cohen's d effect size (ES), % change scores).\n\nRESULTS: Very strong correlations existed between composite scores. The KDSm under-classified upper limb abnormality, whereas the KDSw captured the majority of ABI participants. All scores had moderate-strong correlations with subjective rating of abnormal upper limb movements (r = 0.54 - 0.79) and very strong test-retest reliability (ICCs > 0.81). The APSam demonstrated a 16% (ES = 0.76) walking speed-related increase in upper limb abnormality, whilst decreases were demonstrated in the KDSm 26% (ES 0.90) and KDSw 35% (ES 0.96).\n\nSIGNIFICANCE: The APSam, KDSw, and number of abnormal joint axes comprehensively assess the whole upper limb abnormal movements, accurately classifies abnormality, and quantifies severity. This study illustrated notable presence of abnormal upper limb movements at self-selected walking speed and small increase at fast speeds.

A subset of 30 chronic brain injury participants (mean time post injury: 8.2 ± 9.3 years) were reassessed one week later for retest reproducibility. Three experienced neurological physiotherapists (mean experience: 22.7 ± 9.1 years) viewed these videos and subjectively rated the upper limb associated reactions. Strong-to-very strong test-retest, intra- and inter-rater reproducibility was found for elbow flexion angle (ICC > 0.86) and the Qualifiers Scale applied to global and individual upper limb joints (ICC > 0.60). Responsiveness of change from self-selected to fast walking speed (mean increase 0.46 m/s) was highest for elbow flexion angle (effect size = 0.83) and low-to-moderate for the Qualifiers Scale.\n\nCONCLUSION: Subjectively rated associated reactions during walking demonstrated strong reproducibility and moderate responsiveness to speed change.

Recent research has developed interventions that aim to improve motor outcomes in a variety of paediatric cohorts using video gaming equipment. Therefore, we aimed to systematically review the literature on virtual reality or video game interventions that aim to improve motor outcomes in children with DCD.\n\nMETHODS: Seven databases were searched for studies using the following criteria: a) virtual reality or video game based intervention; b) children with DCD; and c) motor outcomes relating to body structure and function, activity or participation. Data were extracted relating to study design, participant characteristics, details of the intervention, outcome measures, results, and feasibility/adherence.\n\nRESULTS: Fifteen articles were included for review, including eight randomised controlled trials. No studies used virtual reality equipment, with all interventions using video games (Nintendo Wii in 12/15 articles). Mixed effects of video game intervention on outcome were found, with conflicting evidence across studies. Studies that reported on feasibility found most children enjoyed and adhered to the video game interventions.\n\nCONCLUSIONS: This review found limited evidence for the effectiveness of video game interventions for children with DCD to improve motor outcomes due to limitations in the research including low sample sizes and low to moderate methodological quality. Further research is needed to determine the effect of video game or virtual reality interventions on motor outcomes in children with DCD.\n\nPROTOCOL REGISTRATION: The protocol for this systematic review can be found on PROSPERO ( CRD42017064427 ).", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/30651097/", "type": "review", "institutions": [{"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Benjamin F.

This study aimed to investigate the predictive strength of gait and balance variables for evaluating post-stroke falls risk over 12 months following rehabilitation discharge.\n\nMETHODS: A prospective cohort study was undertaken in inpatient rehabilitation centres based in Australia and Singapore. A consecutive sample of 81 individuals (mean age 63 years; median 24 days post stroke) were assessed within one week prior to discharge. In addition to comfortable gait speed over six metres (6mWT), a depth-sensing camera (Kinect) was used to obtain fast-paced gait speed, stride length, cadence, step width, step length asymmetry, gait speed variability, and mediolateral and vertical pelvic displacement. Balance variables were the step test, timed up and go (TUG), dual-task TUG, and Wii Balance Board-derived centre of pressure velocity during static standing. Falls data were collected using monthly calendars.\n\nRESULTS: Over 12 months, 28% of individuals fell at least once. The faller group had increased TUG time and reduced stride length, gait speed variability, mediolateral and vertical pelvic displacement, and step test scores (P < 0.001-0.048). Significant predictors, when adjusted for country, prior falls and assistance (i.e., physical assistance and/or gait aid use) were stride length, step length asymmetry, mediolateral pelvic displacement, step test and TUG scores (P < 0.040; IQR-odds ratio(OR) = 1.37-7.85). With comfortable gait speed as an additional covariate, to determine the additive benefit over standard clinical assessment, only mediolateral pelvic displacement, TUG and step test scores remained significant (P = 0.001-0.018; IQR-OR = 5.28-10.29).\n\nCONCLUSIONS: Reduced displacement of the pelvis in the mediolateral direction during walking was the strongest predictor of post-stroke falls compared with other gait variables.

However, the forces and relationship to land-based functional movement is unknown.

Vertical ground reaction force and pain rating was measured in each environment.\n\nRESULTS: Force in all exercises was significantly greater on land than in chest depth water (p < 0.005). Peak force was significantly greater at maximal speed compared to slow speed (p < 0.001). The pattern of force in squats at slow speed in water was different to on land, with force highest at the start and end of the exercise and decreasing in the central phase. Pain ratings were significantly lower (p < 0.001) in water compared to on land in squats.\n\nCONCLUSIONS: Closed kinetic chain exercises offer inherently different loading in an aquatic environment. Body weight squats and calf raises in water could be defined as either neuromotor or low load, high velocity training.

Twenty-seven participants had joint power generation assessed (three-dimensional gait analysis). Bivariate associations were examined using Spearman's correlations. Regression models with partial F tests were used to compare the contribution to gait between measures.\n\nRESULTS: Although all muscle groups demonstrated significant associations with gait velocity (ρ = 0.40-0.72), partial F tests identified that ankle plantar flexor and hip flexor strength made the largest contribution to gait velocity. Ankle plantar flexor strength also had strong associations with habitual and fast-paced ankle power generation (ρ = 0.65 and 0.75). Balance had significant associations with habitual and fast gait velocity (ρ = -0.57 and -0.53), with partial F tests showing that the contribution was independent of strength.\n\nCONCLUSIONS: Ankle plantar flexor and hip flexor strength had the largest contribution to gait velocity. Future research may wish to refocus strength assessment and treatment to target the ankle plantar flexors and hip flexors.\n\nTO CLAIM CME CREDITS: Complete the self-assessment activity and evaluation online at http://www.physiatry.org/JournalCME CME OBJECTIVES: Upon completion of this article, the reader should be able to: (1) Differentiate the contribution that lower limb strength of each muscle group has on gait velocity after stroke; (2) Appraise the relationship between isometric strength and joint power generation during gait; and (3) Interpret the contribution of both strength and balance to gait after stroke.\n\nLEVEL: Advanced ACCREDITATION: The Association of Academic Physiatrists is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians.The Association of Academic Physiatrists designates this Journal-based CME activity for a maximum of 1.0 AMA PRA Category 1 Credit(s).

The aim of this study was to assess the association between knee biomechanics and knee laxity during hopping and clinically assessed knee function (i.e., patient-reported knee function and hop tests) following ACLR.\n\nMETHODS: Sixty-six participants (23 women, mean age 28 ± 6 years, mean 18 ± 3 months following ACLR) completed a standardized single-leg hopping task. Three-dimensional movement analysis was used to assess knee flexion excursion and body weight/height normalized knee flexion moments during landing for the involved limb. Anterior-posterior knee laxity was assessed with a KT-1000 knee arthrometer. Participants then completed a patient-reported knee function questionnaire and three separate hop tests (% of uninvolved limb) and were divided into poor and satisfactory knee function groups (satisfactory: ≥85% patient-reported knee function and ≥ 85% hop test symmetry). Associations between knee function and hop biomechanics/knee laxity were assessed using logistic regression and interquartile range scaled odds ratios (OR IQR ).\n\nRESULTS: Greater knee flexion excursion (OR IQR 2.9, 95%CI 1.1-7.8), greater knee flexion moment (OR IQR 4.9, 95%CI 1.6-14.3) and lesser knee laxity (OR IQR 4.7, 95%CI 1.5-14.9) were significantly associated with greater odds of having satisfactory knee function (≥ 85% patient-reported knee function and ≥ 85% hop test symmetry).\n\nCONCLUSION: Greater knee flexion excursion/moment during hop-landing and lesser knee laxity is associated with better patient-reported knee function and single-leg hop test performance following ACLR. Patients with lower levels of knee function following ACLR demonstrated hop-landing biomechanics previously associated with early patellofemoral osteoarthritis. Therefore, interventions aimed at improving hop landing biomechanics in people with poor knee function are likely required.\n\nLEVEL OF EVIDENCE: III, Cross-sectional study.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/30293181/", "type": "article", "institutions": [{"id": "https://openalex.org/I4210121067", "name": "Monash Health", "country": "AU", "collaborators": ["Luke Perraton"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02t1bej08"}, {"id": "https://openalex.org/I56590836", "name": "Monash University", "country": "AU", "collaborators": ["Luke Perraton"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02bfwt286"}, {"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Kay M.

Muscle weakness is a key physical impairment that limits walking in commonly occurring neurologic conditions such as cerebral palsy, traumatic brain injury, and stroke. Few randomized trials to date have shown conclusively that strength training improves walking in people living with these conditions. This appears to be because (1) the most important muscle groups for forward propulsion when walking have not been targeted for strengthening, and (2) strength training protocols have focused on slow and heavy resistance exercises, which do not improve the fast muscle contractions required for walking. We propose a theoretical framework to improve exercise prescription by integrating the biomechanics of walking with the principles of strength training outlined by the American College of Sports Medicine to prescribe exercises that are specific to improving the task of walking. The high angular velocities that occur in the lower limb joints during walking indicate that resistance exercises targeting power generation would be most appropriate. Therefore, we propose the prescription of plyometric and ballistic resistance exercise, applied using the American College of Sports Medicine guidelines for task specificity, once people with neurologic conditions are ambulating, to improve walking outcomes. This new theoretical framework for resistance training ensures that exercise prescription matches how the muscles work during walking.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/30690011/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Gavin Williams", "Adam L.

Eligible participants were allocated (1:1) to usual care (UC) plus 8 weeks of aerobic and resistance exercise with behaviour change strategies and symptom support (intervention group (IG)) or UC alone. Assessments occurred at baseline, 9 weeks and 6 months. The primary outcome, change in between-group 6 min walk distance (6MWD), was analysed using intention-to-treat (ITT).

The outcome of interest was mobility limitations on post-TKA day 3, and this was determined a priori by an ordinal mobility outcome hierarchy based on the type of the gait aids prescribed and the level of physiotherapist assistance provided.

We developed a prediction model for 6-month knee range of motion, knee pain, and walking limitations in patients undergoing TKA surgery. Patients and methods - We performed a prospective cohort study of 4,026 patients who underwent elective, primary TKA between July 2013 and July 2017. Candidate predictors included demographic, clinical, psychosocial, and preoperative outcome measures. The outcomes of interest were (i) knee extension and flexion range of motion, (ii) knee pain rated on a 5-point ordinal scale, and (iii) self-reported maximum walk time at 6 months post TKA. For each outcome, we fitted a multivariable proportional odds regression model with bootstrap internal validation. Results - At 6 months post TKA, around 5% to 20% of patients had a flexion contracture ³ 10°, range of motion < 90°, moderate to severe knee pain, or a maximum walk time £ 15 minutes. The model c-indices (the probabilities to correctly discriminate between 2 patients with different levels of follow-up TKA outcomes) when evaluating these patients were 0.71, 0.79, 0.65, and 0.76, respectively. Each postoperative outcome was strongly influenced by the same outcome measure obtained preoperatively (all p-values < 0.001). Additional statistically significant predictors were age, sex, race, education level, diabetes mellitus, preoperative use of gait aids, contralateral knee pain, and psychological distress (all p-values < 0.001). Interpretation - We have developed models to predict, for individual patients, their likely post-TKA levels of knee extension and flexion range of motion, knee pain, and walking limitations.

Strength testing after anterior cruciate ligament reconstruction: A prospective cohort study investigating overlap of tests. J Strength Cond Res 33(11): 3145-3150, 2019-The purpose of the present study was to determine whether overlap (redundancy) exists between individual tests in a comprehensive strength testing protocol used after anterior cruciate ligament reconstruction (ACLR). If overlap is present, one or more components of the protocol could potentially be omitted to make the testing protocol more efficient, but without compromising the usefulness of the testing. Sixty-nine patients (46 male and 23 female patients; mean age 28 years) were strength tested at 6 and 12 months after ACLR as part of a prospective cohort study. The following knee flexor and extensor strength tests were performed: isokinetic concentric strength at 60 and 180°·s, isokinetic eccentric strength at 60°·s, and isometric knee flexor strength at 60° flexion. Peak and average torque values were extracted, and the ratio between the operated and non-operated limb was calculated as a limb symmetry index. Overlap of strength tests was investigated by fitting a linear regression model to the data with an R threshold of 0.56 used as an indication of overlap. Overlap between peak and mean torque was present for extensor and flexor concentric and eccentric measurements at 12 months and for concentric measurements at 6 months. Peak torque measurements were therefore used for subsequent analysis. Concentric extensor peak torque at 60 and 180°·s showed overlap at 6 months (R = 0.73) but not at 12 months (R = 0.37). No other overlap was identified. In conclusion, there is little room for omission of individual strength testing protocol components because of the lack of overlap between tests. Isometric, eccentric, and concentric tests may all provide unique information and all, therefore, should be considered for inclusion.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/29461417/", "type": "article", "institutions": [{"id": "https://openalex.org/I149704539", "name": "Deakin University", "country": "AU", "collaborators": ["Kristoffer Weisskirchner Barfod", "Julian A.

Despite this, there is no gold-standard outcome measure and no kinematic description of this movement disorder. The aim of this study was to determine the upper limb kinematic variables most frequently affected by ARs in people with ABI compared with a healthy cohort at matched walking speed intention.\n\nMETHODS: A convenience sample of 36 healthy control adults (HCs) and 42 people with ABI who had upper limb ARs during walking were recruited and underwent assessment of their self-selected walking speed using the criterion-reference three dimensional motion analysis (3DMA) at Epworth Hospital, Melbourne. Shoulder flexion, abduction and rotation, elbow flexion, forearm rotation and wrist flexion were assessed. The mean angle, standard deviation (SD), peak joint angles and total joint angle range of motion (ROM) were calculated for each axis across the gait cycle. On a group level, ANCOVA was used to assess the between-group differences for each upper limb kinematic outcome variable. To quantify abnormality prevalence on an individual participant level, the percentage of ABI participants that were outside of the 95% confidence interval of the HC sample for each variable were calculated.\n\nRESULTS: There were significant between-group differences for all elbow and shoulder abduction outcome variables (p < 0.01), most shoulder flexion variables (except for shoulder extension peak), forearm rotation SD and ROM and for wrist flexion ROM. Elbow flexion and shoulder abduction were the axes most frequently affected by ARs. Despite the elbow being the most prevalently affected (38/42, 90%), a large proportion of participants had abnormality, defined as ±1.96 SD of the HC mean, present at the shoulder (32/42, 76%), forearm (20/42, 48%) and wrist joints (10/42, 24%).\n\nCONCLUSION: This study provides valuable information on ARs, and highlights the need for clinical assessment of ARs to include all of the major joints of the upper limb.

When combined with point cloud and skeleton pose tracking software they can be used to assess many different aspects of physical function and anatomy. These assessments have received great interest over the past decade, and will likely receive further study as the integration of depth sensing and augmented reality smartphone cameras occurs more in everyday life.\n\nRESEARCH QUESTION: The aim of this review is to discuss how these devices work, what options are available, the best methods for performing assessments and how they can be used in the future.\n\nMETHODS: Firstly, a review of the Microsoft Kinect devices and associated artificial intelligence, automated skeleton tracking algorithms is provided. This includes a narrative critique of the validity and clinical utility of these devices for assessing different aspects of physical function including spatiotemporal, kinematic and inverse dynamics data derived from gait and balance trials, and anatomical assessments performed using the depth sensor information. Methods for improving the accuracy of data are examined, including multiple-camera systems and sensor fusion with inertial monitoring units, model fitting, and marker tracking. Secondly, alternative hardware, including other structured light and time of flight methods, stereoscopic cameras and augmented reality leveraging smartphone and tablet cameras to perform measurements in three-dimensional space are summarised. Software options related to depth sensing cameras are then discussed, focussing on recent advances such as OpenPose and web-based methods such as PoseNet.\n\nRESULTS AND SIGNIFICANCE: The clinical and non-laboratory utility of these devices holds great promise for physical function assessment, and recent developments could strengthen their ability to provide important and impactful health-related data.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/30500731/", "type": "review", "institutions": [{"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Benjamin F.

With custom-written software, the Wii Balance Board (WBB) has been shown to be a valid and reliable force platform that can be used to assess standing balance. However, no studies to date have assessed the use of the more readily available Wii Stillness Score (WSS) as a measure of balance.\n\nMETHODS: Twenty-four individuals without lower limb pathology performed a combination of unilateral and double leg standing balance tests with eyes open or closed on two separate occasions. At each session, data from the WBB were acquired on a laptop computer running custom software and then by Wii-Fit software on a Wii console. The reliability of the WSS was determined by assessing reproducibility, while the validity of the WSS was determined by comparing the results of the WSS to that of the custom-written software.\n\nRESULTS: We found that the WSS exhibited excellent intra and inter device reliability in three out of four stances tested. The Bland-Altman plots also showed good concurrent validity for the three analysed stances. However, there remain significant limitations with the use of the WSS such as its rigid thirty-second time parameter and single score result.\n\nCONCLUSION: The readily available WBB may be a used as a portable and inexpensive device to assess standing balance with custom written software.

Light detection and ranging laser technology provides a continuous stream of distance data.

Therefore, the aim of this study was to assess the validity of a novel, low-cost and easy to implement laser-based system during walking and running trials.\n\nDESIGN: Cross-sectional study.\n\nMETHODS: Thirty-two healthy adults performed walking and running trials from flying and static starts while monitored concurrently with reference standard three-dimensional motion analysis and laser systems. Velocity was calculated over short (0.5m) and longer (3m) intervals using both systems. Validity was assessed using absolute agreement intraclass correlation coefficients (ICC 2,1 ), mean absolute errors, Pearson's correlations and regressions and Bland-Altman plots.\n\nRESULTS: All intraclass correlation coefficients and correlations were excellent (ICC>0.88, R>0.89). For the longer interval, all mean absolute errors were <0.03m/s (0.24-1.31%). Slightly higher mean absolute error values were reported for the shorter interval (3.16-5.10%), with the highest error of 0.184m/s evident for the flying start running trial.\n\nCONCLUSIONS: These results indicate that a low-cost and accessible laser system can be used to accurately assess walking and running speed.

Methods: a population-based sample of 2,987 patients undergoing primary TKA participated, of whom 2015 (68%) were 65 years of age or older. At 4, 8 and 12 weeks post surgery, knee flexion range-of-motion, quadriceps strength and fast gait speed were quantified.

This study examined several characteristics that might explain impaired postural stability in a group of older adults with neck pain, and compared the results in this cohort with that of asymptomatic controls. In this cross-sectional study we compared physical activity, lower limb motor and sensory function, vestibular and visual function, falls efficacy and dizziness handicap in 84 older adults with (n=35, age 69.6±6.3) and without (n=49, age 69.4±4.7) idiopathic neck-pain. Additionally, dynamic balance was assessed using the dynamic gait index (DGI) and standard and wavelet analysis of static balance was computed after data capture. Physical activity levels, lower limb motor and sensory function, vestibular function and visual contrast sensitivity were not different between groups (p>0.05). The neck-pain group demonstrated higher falls efficacy (p=0.01), greater levels of dizziness handicap (p<0.01), and higher CoP velocity measures in the moderate (1.56-6.25Hz) and low (0.39-1.56Hz) frequency bandwidths. Our results suggest that neck-pain induced postural control deficits in older adults may not be associated with the physical activity levels, lower limb motor and sensory function, or vestibular and visual function. Inferring from wavelet analysis results, we speculated that sensory re-weighting may have occurred to compensate for the deficits in neck proprioception.

Peripheral quantitative computed tomography assessed muscle density and cortical volumetric BMD (vBMD), area, thickness, and strength-strain index (SSI) at 66% tibial length. Hand grip strength (dynamometry) and balance path length (computerised posturography) were assessed. Obesity was defined as high body fat percentage.\n\nRESULTS: Greater lower-leg muscle density was associated with lower balance path length in men (r = -0.36; P < .01) and women (r = -0.40; P = < .01). Obese participants by body fat percentage did not differ to non-obese on bone indices, although a trend towards lower cortical vBMD was observed in obese compared with non-obese men (1041.4 ± 39.8 vs 1058.8 ± 36.1 mg/cm 3 ; P = .051). In multivariable models, ALM was positively associated with all bone parameters in obese women, and with whole-body aBMD, proximal tibial cortical area and SSI in non-obese women, and both non-obese and obese men (all P < .05). Lower-leg muscle density was also positively associated with cortical vBMD (B = 2.91; 95% CI 0.02, 5.80) and area (2.70; 0.06, 5.33) in obese women.\n\nCONCLUSIONS: Amongst components of sarcopenic obesity, higher ALM is a consistent independent predictor of better bone health.

This study aimed to, in patients with a recent TKA, examine the associations of isometric and isotonic quadriceps strength with gait speed, accounting for knee pain experienced during testing. METHODS: A sample of 76 patients (mean age 68 years; 46 women) with a recent TKA (median, 1.5 months) participated. Quadriceps strength was measured on both limbs using a knee extension machine. Isotonic strength was assessed with a one-repetition maximum test. Isometric strength was measured at 40° and 70° of knee flexion using a custom-built load cell. To allow for valid comparisons between the tests, quadriceps strength symmetry ratios were calculated. Knee pain during testing was measured using an 11-point pain scale. Fast gait speed was measured using the 10-m walk test. RESULTS: Compared with isotonic test, quadriceps strength ratio was higher for the 40° flexion isometric test (P = 0.01), and this difference may be explained by the lower knee pain intensity elicited during the isometric tests (P's < 0.001). All strength measures were closely associated with fast gait speed after adjustment for knee pain and covariates (P's < 0.001). CONCLUSIONS: Early in the post-TKA period, isometric and isotonic strength tests may be used to assess quadriceps strength but these tests are not interchangeable. Isometric quadriceps testing may be preferable to isotonic testing as it was associated with lower knee pain intensity.", "abstractSource": "https://openalex.org/W2810514111", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Cheryl Lian-Li Poon", "Choo-Lye Ho", "Foh-Lik Leong", "Hwei‐Chi Chong", "Edwin Choon-Wyn Lim"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I4210159875", "name": "Sengkang General Hospital", "country": "SG", "collaborators": ["Felicia Jie‐Ting Seah"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.3956650495529175, "longitude": 103.89337921142578}, "ror": "https://ror.org/05cqp3018"}, {"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Benjamin F.

The search strategy included terms relating to sitting, balance and postural control. Two reviewers independently selected and extracted data from the identified articles and assessed the methodological quality of the papers using the COnsensus-based Standards for selection of health status Measurement INstruments (COSMIN) checklist.\n\nRESULTS: Fourteen clinical sitting measurement scales (39 papers) containing dynamic tasks met the inclusion criteria and various measurement properties were evaluated. The methodological quality of the majority of the included studies was rated as poor to fair using the COSMIN checklist, with common limitations including small sample size and inappropriate use of statistical methods.\n\nCONCLUSIONS: This review was unable to identify measures with sufficient psychometric properties to enable recommendation as preferred tools. However, measures were identified that warrant further specific psychometric investigations to fulfil requirements for a high quality measure. Implications for Rehabilitation Fourteen clinical sitting balance scales containing dynamic tasks are available to measure sitting balance with individuals following stroke. No single scale has sufficient psychometric properties to enable recommendation as a preferred tool for measuring sitting balance with stroke survivors. Use of a balance scale or dedicated sitting balance measure containing static and dynamic sitting items should be utilised to monitor progress for individuals following stroke with more severe deficits.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/28029054/", "type": "review", "institutions": [{"id": "https://openalex.org/I205640436", "name": "Curtin University", "country": "AU", "collaborators": ["Melissa Birnbaum", "Keith Hill"], "geo": {"city": "Perth", "geonames_city_id": "2063523", "region": "Western Australia", "country_code": "AU", "country": "Australia", "latitude": -31.95224, "longitude": 115.8614}, "ror": "https://ror.org/02n415q13"}, {"id": "https://openalex.org/I4210087110", "name": "St Vincent's Hospital Melbourne", "country": "AU", "collaborators": ["Melissa Birnbaum", "Rita Kinsella", "Susan Black", "Kim Brock"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/001kjn539"}], "provenance": ["https://openalex.org/W2563749027", "https://pubmed.ncbi.nlm.nih.gov/28029054/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85040010834&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85040010834&origin=inward", "scopusDoi": "10.1080/09638288.2016.1261947"}, {"id": "W2808421590", "title": "Correspondence: Time-based versus repetition-based sit-to-stand measures: choice of metrics matters", "year": 2018, "doi": "10.1016/j.jphys.2018.05.010", "url": "https://doi.org/10.1016/j.jphys.2018.05.010", "authors": ["Yong‐Hao Pua", "Julian Thumboo", "Ross A.

Quality of trials was determined using the Cochrane Risk of Bias Tool. Trials were scored based on their protocol's adherence to 8 ACSM recommendations. To determine if a relation existed between total adherence score and effect size, Spearman ρ was calculated, and between individual recommendations and effect size, Mann-Whitney U or Kruskal-Wallis tests were used.\n\nDATA SYNTHESIS: Thirty-nine trials met the inclusion criteria, and 34 were scored on their adherence to the guidelines. Adherence was high for frequency of training (100% of studies), but few trials adhered to the guidelines for intensity (32%), specificity (24%), and training pattern (3%). Based on the small number of studies that could be included in pooled analysis (n=12), there was no relation between overall adherence and effect size (Spearman ρ=-.39, P=.21).\n\nCONCLUSIONS: Adherence to the ACSM guidelines for resistance training after stroke varied widely.

Secondary outcomes included measures of mobility, lower limb muscle strength, muscle power, and quality of life.\n\nRESULTS: A total of 30 participants (11% of those screened) with mean age of 50 years (SD 18) were randomized. The median number of sessions attended was 15 of 18 and 17 of 18 for the ballistic and control groups, respectively. Earlier than expected discharge to home (n=4) and illness (n=7) were the most common reasons for nonattendance. Participants performed the exercises safely, with no study-related adverse events. There were significant (P<.05) between-group changes favoring the ballistic group for comfortable gait velocity (mean difference [MD] 0.31m/s, 95% confidence interval [CI]: 0.08-0.52), muscle power, as measured by peak jump height (MD 8cm, 95% CI: 3-13), and peak propulsive velocity (MD 64cm/s, 95% CI: 17-112).\n\nCONCLUSIONS: Ballistic training was safe and feasible in select ambulant people with stroke.

Aims: Assess the efficacy of home-based rehabilitation compared with usual care (UC) at active treatment commencement for inoperable lung cancer. Methods: Multi-site, stratified, assessor-blinded RCT (concealed allocation), with intention-to-treat. Participants received UC plus 8-weeks of aerobic and resistance exercise with weekly behavior change and symptom management telephone support (intervention group [IG]) or UC. Primary outcome was between-group change in six-minute walk (6MWD) from baseline to 9-weeks. Secondary outcomes included; physical activity (PA), muscle strength, HRQoL, symptoms and exercise motivation measured at baseline, 9-weeks and 6-months (Edbrooke, L. et al. BMC Cancer 2017; 17:633). Results: 92 participants were recruited (45 IG, 47 UC): mean (SD) age 64 (12) years; male 55%; disease stage n (%) III=35 (38) and IV=48 (52); radical treatment intent n (%) 42 (46).

Two surface electrode sets (connected to the low-cost and the commercial system) were placed end to end along the same Vastus Lateralis muscle fibre line. Peak and mean contraction intensity, and contraction duration were analysed. Overall the relative agreement between systems was excellent for peak muscle activation (ICC 0.77-0.96) and modest to excellent for mean muscle activation (ICC 0.68-0.95) and contraction duration (ICC 0.65-0.99). Inter-tester, intra-session reliability was excellent for peak contraction intensity (ICC > 0.99) and modest to excellent for mean contraction intensity, with the TKEO method primarily recording stronger agreement than the manual method.

There is currently no normative dataset for joint angular velocity during walking, which would be useful to allow comparisons for patient cohorts. Additionally, understanding normal joint angular velocity may assist clinical assessment and treatment procedures to incorporate methods that replicate the movement speed of the lower limb joints during walking.\n\nRESEARCH QUESTION: This study aimed to examine lower limb joint angles and angular velocities in a healthy population walking at various gait speeds.\n\nMETHODS: Thirty-six healthy adult participants underwent three-dimensional gait analysis while walking at various speeds during habitual and slowed walking. The peak joint angles and angular velocities during important phases of the gait cycle were examined for the hip, knee and ankle in the sagittal plane. Data were grouped in 0.2 m/s increments from a walking speed of 0.4 m/s to 1.6 m/s to represent the range of walking speeds reported in studies of people with gait impairments.\n\nRESULTS: For joint angles and angular velocities, the shape of the gait traces were consistent regardless of the walking speed. However as walking speed increased, so did the peak joint angles and angular velocities for the hip, knee and ankle. The largest angular velocity occurred when the knee joint extended at the terminal swing phase of gait. For the ankle and hip joints, the largest angular velocity occurred during the push-off phase.\n\nSIGNIFICANCE: This study examined how lower limb joint angular velocities change with various walking speeds. These data can be used as a comparator for data from clinical cohorts, and has the potential to be used to match clinical assessment and treatment methods to joint angular velocity during walking.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/30558929/", "type": "article", "institutions": [{"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Benjamin F.

Clinical utility was explored through visual analysis of the Wii Balance Board-derived data. Participant retention was 100%. Cessation of testing due to discomfort or fatigue occurred 20% of the time. For the static balance tasks, mediolateral amplitude emerged as a variable of interest. Wii Balance Board-derived centre of pressure data from static sitting and standing tasks appeared to capture useful information about individuals with varying degrees of lateropulsion and displayed change over time.

Ultrasound imaging of both Achilles tendons was also performed by one blinded assessor, and the anteroposterior (AP) thickness and presence of pathology was determined. Comparisons were made between symptomatic and asymptomatic sides for key outcomes, and correlation between COP path length and variables of interest were investigated.\n\nRESULTS: Symptomatic Achilles tendons demonstrated significantly increased AP tendon thickness (p<0.001). Participants with AT demonstrated increased COP path length (sway amplitude) on their affected side during the eyes closed task (p=0.001). Increased tendon thickness was associated with increased sway amplitude during the eyes open task on both the affected (rho=0.44, p=0.045) and unaffected sides (rho=0.62, p=0.003).\n\nCONCLUSIONS: In males with AT, single-leg standing balance with eyes closed is impaired on the symptomatic side. This indicates that neuromuscular deficits affecting functional ability may be present in people with AT during more challenging balance activities.

Test-retest reliability is therefore imperative; however, many variations of gait models currently exist.\n\nRESEARCH QUESTION: This study examined the test-retest reliability of, and agreement between, two commonly used methods of gait modelling, a modified Conventional Gait Model and cluster-based model, using both six degrees-of-freedom or inverse kinematics computational methods in Visual3D.\n\nMETHODS: Thirty healthy participants attended two identical sessions. The data for both models were collected concurrently and analysed in Visual3D using either six degrees-of-freedom or inverse kinematics computational methods. Outcomes were taken as the peak measurements for kinematics (joint angles and angular velocity) and kinetics (joint moments and power) for the hip, knee and ankle. Intraclass correlation coefficients were used to examine reliability, with the standard error of measurement and minimal detectable change also calculated. Agreement between models was examined with Pearson correlations and intraclass correlation coefficients.\n\nRESULTS: Test-retest reliability was good to excellent for all models for lower limb kinematics and kinetics. The inverse kinematic models had slightly lower reliability across outcomes compared to the six degrees-of-freedom models. Agreement between the Conventional Gait Model and cluster model was mostly good to excellent. Comparison of the two modified CGMs (with six degrees-of-freedom and inverse kinematics) showed much higher agreement against the comparison of the two cluster-based models (with six degrees-of-freedom and inverse kinematics).\n\nSIGNIFICANCE: This study provides a comprehensive assessment of the test-retest reliability and agreement between two gait models with various computational methods.

However, the typically utilised methods are limited to pinch or grip dynamometers and do not readily translate to handling everyday objects. With the advent of consumer-grade 3D printing and low-cost sensor systems, the possibilities for creating customised assessment devices are expanding. As a first step in determining the validity of low-cost sensor systems, their data must be compared to a gold standard. Consequently, this study examined the criterion validity of two such systems for measuring pinch strength, specifically a small load cell and pressure-sensing fabric, with a mechanical pinch gauge.\n\nMETHODS: A total of 33 participants performed strength tests using a mechanical pinch grip device, which had a plastic 3D printed cover with a pressure-sensing fabric overlaid on it to allow for simultaneous criterion validation, and a small load cell with a plastic 3D printed casing designed for comfortable pinch grip assessment.\n\nRESULTS: The simultaneously assessed fabric sensor and mechanical pinch grip device showed excellent absolute (ICC 2,k = 0.94) and relative (Pearson's R = 0.90) agreement. Both devices showed similar excellent relative (R > 0.75) agreement with the load cell despite non-simultaneous assessment. These findings indicate that 3D printed sensors incorporating a load cell and a pressure-sensing fabric can be used to replicate a pinch grip assessment performed with a mechanical pinch gauge.\n\nCONCLUSIONS: This study lays the foundation for these sensor systems to be modified for use as assessment tools during the performance of functional tasks using everyday objects. Additionally, because both systems generate real-time force data they could be used for biofeedback as part of rehabilitation and strengthening programs.

This study aimed to assess the relationship between poor self-reported or clinically measured knee function and knee moments/vertical ground reaction force (vGRF) in individuals following ACLR.\n\nMETHODS: 61 participants (mean 16.5 ± 3 months following ACLR, 23 women) completed a patient-reported knee function questionnaire and three hop tests (% of uninvolved limb). Participants were divided into satisfactory and poor knee function groups (poor < 85% patient-reported knee function and/or < 85% hop test symmetry). The knee biomechanics of both groups were assessed with three-dimensional motion analysis during the stance phase of overland running at self-selected speeds, and the association between knee function and knee moments was assessed using analysis of covariance with running speed as a covariate.\n\nRESULTS: Participants with poor knee function (n = 30) ran with significantly smaller peak knee flexion moments (moderate effect size 0.7, p = 0.03) and significantly smaller peak vGRFs (large effect size 1.0, p = 0.002) compared to those with satisfactory knee function (n = 31). No significant differences were observed for knee adduction and knee external rotation moments or knee kinematics.\n\nCONCLUSION: Individuals following ACLR with poor self-reported knee function and/or hop test performance demonstrate knee moments during running that may be associated with lower knee joint contact forces.

Results: With ascent from 760 to 3100 m the PL increased in the placebo group from median (quartiles) 29.2 (25.8; 38.2) to 31.5 (27.3; 39.3) cm ( P < 0.05); in the dexamethasone group the corresponding increase from 28.8 (22.8; 34.5) to 29.9 (25.2; 37.0) cm was not significant ( P = 0.10). The mean difference (95% CI) between dexamethasone and placebo groups in altitude-induced changes (treatment effect) was -0.3 (-3.2 to 2.5) cm, ( P = 0.41). Multivariable regression analysis confirmed a significant increase in PL with higher altitude (coefficient 1.6, 95% CI 0.2 to 3.1, P = 0.031) but no effect of dexamethasone was shown (coefficient -0.2, 95% CI -0.4 to 3.6, P = 0.925), even when controlled for several potential confounders. PL changes were related more to antero-posterior than lateral sway. Twenty-two of 104 patients had an altitude-related increase in the antero-posterior sway velocity of >25%, what has been associated with an increased risk of falls in previous studies. Conclusion: Lowlanders with COPD travelling from 760 to 3100 m revealed postural instability 24 h after arriving at high altitude, and this was not prevented by dexamethasone.

The primary purpose of this study was to investigate whether the interplay between prefrontal and motor cortex activity could predict such age-related performance deficits. Using a dual-task (DT) paradigm, 15 younger and 15 older adults participated in experiment 1, where brain activity was simultaneously measured using functional near infrared spectroscopy (fNIRS) and transcranial magnetic stimulation (TMS). Experiment 1 demonstrated poorer performance for the older group across a range of DTs combining visuomotor arm tracking with a secondary cognitive or motor task. Interestingly however, older adults' DT performance error was isolated to the motor component of DTs. TMS data revealed reduced motor cortex (M1) inhibition during DTs for older adults, and a trend for this correlating with poorer performance. In contrast, poorer performing younger adults showed significantly higher M1 inhibition. Experiment 2 was conducted given a high amount of movement artifact in experiment 1 fNIRS data. Using fNIRS to measure prefrontal, premotor, and motor cortex activity in an additional 15 older adults, we found no evidence of an interplay between these regions predicting DT performance. Nevertheless, performance data replicated experiment 1 in showing that DT error was isolated to motor tasks in older adults, with no significant cognitive task error. Overall, this study shows that older adults seemed to adopt a 'cognitive-first' prioritisation strategy during the DTs involved in our study, and that deficits in DT performance may be related to the modulation of M1 inhibitory mechanisms. We propose that clinicians advise older adults to allocate greater attention to motor tasks during activities where they may be at risk of accident-related injury.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/30261247/", "type": "article", "institutions": [{"id": "https://openalex.org/I1316535847", "name": "Beth Israel Deaconess Medical Center", "country": "US", "collaborators": ["George J.

Numerous researchers have evaluated the low-cost Wii Balance Board (WBB) for its utility in assessing balance, with variable findings. This review aimed to systematically evaluate the reliability and concurrent validity of the WBB for assessment of static standing balance. Articles were retrieved from six databases (Medline, SCOPUS, EMBASE, CINAHL, Web of Science, Inspec) from 2007 to 2017. After independent screening by two reviewers, 25 articles were included. Two reviewers performed the data extraction and quality assessment. Test-retest reliability was investigated in 12 studies, with intraclass correlation coefficients or Pearson's correlation values showing a range from poor to excellent reliability (range: 0.27 to 0.99). Concurrent validity (i.e. comparison with another force platform) was examined in 21 studies, and was generally found to be excellent in studies examining the association between the same outcome measures collected on both devices. For studies reporting predominantly poor to moderate validity, potentially influential factors included the choice of 1) criterion reference (e.g. not a common force platform), 2) test duration (e.g. <30 s for double leg), 3) outcome measure (e.g. comparing a centre of pressure variable from the WBB with a summary score from the force platform), 4) data acquisition platform (studies using Apple iOS reported predominantly moderate validity), and 5) low sample size. In conclusion, evidence suggests that the WBB can be used as a reliable and valid tool for assessing standing balance.

A key limitation is the disparate signal filtering and analysis techniques, with many methods requiring custom computer programs. This paper discusses the creation of a freely available web-based software program, SeeSway (www.rehabtools.org/seesway), which was designed to provide powerful tools for pre-processing, analysing and visualising standing balance data in an easy to use and platform independent website.\n\nMETHODS: SeeSway links an interactive web platform with file upload capability to software systems including LabVIEW, Matlab, Python and R to perform the data filtering, analysis and visualisation of standing balance data. Input data can consist of any signal that comprises an anterior-posterior and medial-lateral coordinate trace such as center of pressure or mass displacement. This allows it to be used with systems including criterion reference commercial force platforms and three dimensional motion analysis, smartphones, accelerometers and low-cost technology such as Nintendo Wii Balance Board and Microsoft Kinect. Filtering options include Butterworth, weighted and unweighted moving average, and discrete wavelet transforms. Analysis methods include standard techniques such as path length, amplitude, and root mean square in addition to less common but potentially promising methods such as sample entropy, detrended fluctuation analysis and multiresolution wavelet analysis. These data are visualised using scalograms, which chart the change in frequency content over time, scatterplots and standard line charts. This provides the user with a detailed understanding of their results, and how their different pre-processing and analysis method selections affect their findings.\n\nRESULTS: An example of the data analysis techniques is provided in the paper, with graphical representation of how advanced analysis methods can better discriminate between someone with neurological impairment and a healthy control.\n\nCONCLUSIONS: The goal of SeeSway is to provide a simple yet powerful educational and research tool to explore how standing balance is affected in aging and clinical populations.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/29650316/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}], "provenance": ["https://openalex.org/W2789094481", "https://pubmed.ncbi.nlm.nih.gov/29650316/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85042795215&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://doi.org/10.1016/j.cmpb.2018.02.019", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85042795215&origin=inward", "scopusDoi": "10.1016/j.cmpb.2018.02.019"}, {"id": "W2892587030", "title": "Strength, not flexibility is responsive to match-play in Australian Football athletes", "year": 2018, "doi": "10.1016/j.jsams.2018.09.144", "url": "https://doi.org/10.1016/j.jsams.2018.09.144", "authors": ["Paula C.

Modifiable risk factors such as hamstring strength deficits and lower limb flexibility measures have previously been identified with respect to increased risk of hamstring strain injury. The aim of this study was to evaluate the variability of clinically feasible lower limb strength and flexibility tests pre- and post-AF match-play to determine their usefulness as injury prevention measures within a secondary prevention program (with the goal of early detection and intervention). Methods: This repeated measures design involved male (n=10 (20 limbs); height, 186.1±6.3 cm; weight 83.5±8.6 kg; age, 21.3±2.2 years) semi-professional AF athletes who completed maximal voluntary isometric hamstring strength (HSIS) and lower limb flexibility measures of the hip, knee and ankle prior to and at three time points ( 14% of group baseline; flexibility: hip, 10◦, knee 10◦, ankle, 2 cm). Statistical significance was determined when the 95%CI did not include 0 (representing no change from baseline). Results: Maximal isometric hamstring strength was significantly reduced at a group level compared to baseline measurements immediately (−122.8 N, 95%CI: −156.2–89.4, p < 0.001) and at 26 h (−89.6 N, 95%CI: −122.9–56.2, p < 0.001) following matchplay. No significant differences from baseline were observed at 50 and 74 h. These observed reductions in force exceeded minimal clinically meaningful changes. Hip, knee and ankle flexibility tests did not reach clinically meaningful changes at any time point. Discussion: Clinically meaningful and statistically significant reductions in maximal isometric hamstring strength are evident for up to 26 h following competitive match-play. This information may have implications for planning recovery timeframes following competition and implementation of routine monitoring. At a group level, isometric strength should return to baseline levels within 50 h and failure to achieve this recovery level may warrant further investigation. Lower limb flexibility measures were not changed from baseline values in a clinically meaningful way and therefore are not recommended for use as routine monitoring in injury prevention.", "abstractSource": "https://www.semanticscholar.org/paper/c06fca937623ccf2ec67b64968be9c636020baf5", "type": "article", "institutions": [{"id": "https://openalex.org/I12240146", "name": "Australian Sports Commission", "country": "AU", "collaborators": ["Sam Rice"], "geo": {"city": "Belconnen", "geonames_city_id": "2176373", "region": "Australian Capital Territory", "country_code": "AU", "country": "Australia", "latitude": -35.23798, "longitude": 149.06627}, "ror": "https://ror.org/01e4w2966"}, {"id": "https://openalex.org/I4387155473", "name": "ACT Government", "country": null, "collaborators": ["Sam Rice"], "geo": {"city": "Canberra", "geonames_city_id": null, "region": null, "country_code": null, "country": "Australia", "latitude": -35.2834587097168, "longitude": 149.12806701660156}, "ror": "https://ror.org/03fy7b149"}], "provenance": ["https://openalex.org/W2892587030", "https://www.semanticscholar.org/paper/c06fca937623ccf2ec67b64968be9c636020baf5"], "identityEvidence": "Established rehabilitation coauthor", "openAccessUrl": null}, {"id": "W2893393234", "title": "The Effect of Walking Speed on Lower Limb Angular Velocity", "year": 2018, "doi": "10.1016/j.apmr.2018.07.041", "url": "https://doi.org/10.1016/j.apmr.2018.07.041", "authors": ["Gavin Williams", "Benjamin F.

Background Quadriceps strength is associated with hop distance and jump height in persons who have undergone anterior cruciate ligament (ACL) reconstruction. However, it is unknown whether the ability to rapidly generate quadriceps torque in the early phase of recovery is associated with future hopping and jumping performance in this population. Objective To evaluate the prospective associations among quadriceps strength and rate of torque development (RTD) and single-leg hop for distance, vertical jump height, vertical ground reaction force (vGRF), and vertical force loading rate during a landing task in persons who have undergone ACL reconstruction. Methods Seventy patients with unilateral ACL reconstruction participated. At 6 weeks post ACL reconstruction, isometric quadriceps strength and RTD were measured using a dynamometer. At 6 months following ACL reconstruction, patients performed the single-leg hop for distance test. Patients also performed the single-leg vertical jump test on a force plate that measured maximum jump height, vGRF, and average loading rate during landing. Results Both quadriceps strength and RTD at 6 weeks post ACL reconstruction were associated with all hopping and jumping measures at 6 months post ACL reconstruction (P≤.04). Single-leg hop distance was associated more closely with quadriceps strength than with quadriceps RTD (P = .05), and vertical jump height and vGRF measures were associated more closely with quadriceps RTD than with quadriceps strength (P = .05 and P<.01, respectively). Both quadriceps measures were associated with loading rate. Conclusion Quadriceps strength and RTD are complementary but distinct predictors of future hopping and jumping performance in persons who have undergone ACL reconstruction. These findings may contribute to improved rehabilitation of patients who are at risk for poor jumping/hopping performance and abnormal knee loading. J Orthop Sports Phys Ther 2017;47(11):845-852.

Due to lack of early specific symptoms, the majority of patients present with advanced, inoperable disease and five-year relative survival across all stages of non-small cell lung cancer (NSCLC) is 14%. People with lung cancer also report higher levels of symptom distress than those with other forms of cancer. Several benefits for survival and patient reported outcomes are reported from physical activity and exercise in other tumour groups. We report the protocol for a study investigating the benefits of exercise, behaviour change and symptom self-management for patients with recently diagnosed, inoperable, NSCLC.\n\nMETHODS: This multi-site, parallel-group, assessor-blinded randomised controlled trial, powered for superiority, aims to assess functional and patient-reported outcomes of a multi-disciplinary, home-based exercise and supportive care program for people commencing treatment. Ninety-two participants are being recruited from three tertiary-care hospitals in Melbourne, Australia. Following baseline testing, participants are randomised using concealed allocation, to receive either: a) 8 weeks of home-based exercise (comprising an individualised endurance and resistance exercise program and behaviour change coaching) and nurse-delivered symptom self-management intervention or b) usual care. The primary outcome is the between-group difference in the change in functional exercise capacity (six-minute walk distance) from baseline to post-program assessment. Secondary outcomes include: objective and self-reported physical activity levels, physical activity self-efficacy, behavioural regulation of motivation to exercise and resilience, muscle strength (quadriceps and grip), health-related quality of life, anxiety and depression and symptom interference.\n\nDISCUSSION: There is a lack of evidence regarding the benefit of exercise intervention for people with NSCLC, particularly in those with inoperable disease receiving treatment. This trial will contribute to evidence currently being generated in national and international trials by implementing and evaluating a home-based program including three components not yet combined in previous research, for people with inoperable NSCLC receiving active treatment and involving longer-term follow-up of outcomes.

Impaired single-limb standing balance has been observed in the ACLR limb compared to healthy individuals. However, it remains inconclusive as to whether these same balance deficits exist between the injured and contralateral uninjured limbs, during challenging balance tasks, and at a time when patients are permitted to return to sport. 100 adults who had undergone a primary hamstring-tendon ACLR 12 months previously (68 male; median[IQR] age: 28.1[14.1] years) performed tests of single-limb standing with the knee in a functional position of 20-30° flexion, with their eyes closed, over 20s (Nintendo Wii Balance Board). Two repetitions were performed on the ACLR and uninjured limb. Measures of postural control included centre of pressure (CoP) path velocity, anterior-posterior and mediolateral range and standard deviation, and were averaged across the two trials. Wilcoxon signed-rank tests showed no significant between-leg differences in single-limb balance for any of the CoP measures of interest (all P values>0.686). Further, multiple linear regression analyses showed no significant associations between concomitant meniscectomy or chondral lesions noted at the time of ACLR and measures of single-limb balance on the ACLR limb one year later (all P values>0.213). In the context of prior research, these findings suggest bilateral balance deficits may exist prior to ACL injury, or appear post ACL-injury or ACLR. Treatment of balance deficits should therefore consider both limbs after ACLR.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/27855310/", "type": "article", "institutions": [{"id": "https://openalex.org/I165143802", "name": "The University of Queensland", "country": "AU", "collaborators": ["Anna L.

The Balance Error Scoring System (BESS) has been proposed as 1 measure of balance assessment. A new, freely available software program to accompany the Nintendo Wii Balance Board (WBB) system has recently been developed but has not been tested in concussed patients.\n\nOBJECTIVE: To evaluate the feasibility of using the WBB to assess postural stability across 3 time points (baseline and postconcussion days 3 and 7) and to assess concurrent and convergent validity of the WBB with other traditional measures (BESS and Immediate Post-Concussion Assessment and Cognitive Test [ImPACT] battery) of assessing concussion recovery.\n\nDESIGN: Cohort study.\n\nSETTING: Athletic training room and collegiate sports arena.\n\nPATIENTS OR OTHER PARTICIPANTS: We collected preseason baseline data from 403 National Collegiate Athletic Association Division I and III student-athletes participating in contact sports and studied 19 participants (age = 19.2 ± 1.2 years, height = 177.7 ± 8.0 cm, mass = 75.3 ± 16.6 kg, time from baseline to day 3 postconcussion = 27.1 ± 36.6 weeks) who sustained concussions.\n\nMAIN OUTCOME MEASURE(S): We assessed balance using single-legged and double-legged stances for both the BESS and WBB, focusing on the double-legged, eyes-closed stance for the WBB, and used ImPACT to assess neurocognition at 3 time points. Descriptive statistics were used to characterize the sample. Mean differences and Spearman rank correlation coefficients were used to determine differences within and between metrics over the 3 time points. Individual-level changes over time were also assessed graphically.\n\nRESULTS: The WBB demonstrated mean changes between baseline and day 3 postconcussion and between days 3 and 7 postconcussion. It was correlated with the BESS and ImPACT for several measures and identified 2 cases of abnormal balance postconcussion that would not have been identified via the BESS.\n\nCONCLUSIONS: When accompanied by the appropriate analytic software, the WBB may be an alternative for assessing postural stability in concussed student-athletes and may provide additional information to that obtained via the BESS and ImPACT.

Reporting standards for exercise interventions were assessed using the Consensus for Exercise Reporting Template (CERT).\n\nRESULTS: A total of 1320 titles were identified with 14 studies satisfying the inclusion criteria, four (29%) of which demonstrated low risk of bias. Ten (71%) studies utilised external load as a component of the exercise intervention.

At 4, 8, 12, and 16 weeks postsurgery, fast gait speed was measured. The factors associated with gait speed over time since TKA were identified using multivariable generalized least squares modeling.\n\nRESULTS: Lower postoperative quadriceps strength and knee flexion range of motion were closely associated with lower gait speed over time (0.084m/s, 0.064m/s, and 0.055m/s change in gait speed per interquartile range change in ipsilateral quadriceps strength, contralateral quadriceps strength, and knee flexion range of motion, respectively). Additional strong predictors of lower gait speed included older age (0.11m/s), lower levels of preoperative Short Form 36 physical function (0.066m/s), greater body mass (0.046m/s), and the preoperative use of a walking aid (overall P < 0.001). Patients who reported that they limited their daily activities due to a fear of falling also had poorer gait speed (0.033m/s and 0.054m/s slower gait speed for \"Occasional\" and \"Often\" categories, respectively, vs. \"None\").\n\nCONCLUSIONS: Gait speed recovery post-TKA is driven by both physical and psychological factors, suggesting that identifying and treating the underlying physical and cognitive causes of gait speed limitations may be crucial to optimize functional recovery.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/27894727/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Felicia Jie‐Ting Seah", "Cheryl Lian-Li Poon", "John Wei-Ming Tan", "Hwei‐Chi Chong"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}], "provenance": ["https://openalex.org/W2547001673", "https://pubmed.ncbi.nlm.nih.gov/27894727/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85007105432&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://doi.org/10.1016/j.semarthrit.2016.10.012", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85007105432&origin=inward", "scopusDoi": "10.1016/j.semarthrit.2016.10.012"}, {"id": "W2776758452", "title": "Falls efficacy, postural balance, and risk for falls in older adults with falls-related emergency department visits: prospective cohort study", "year": 2017, "doi": "10.1186/s12877-017-0682-2", "url": "https://doi.org/10.1186/s12877-017-0682-2", "authors": ["Yong‐Hao Pua", "Peck‐Hoon Ong", "Ross A.

We examined the interaction between falls efficacy and postural balance and its association with future falls. We also investigated the association between falls efficacy and gait decline.\n\nMETHODS: Falls efficacy, measured by the Modified Falls Efficacy Scale (MFES), and standing postural balance, measured using computerized posturography on a balance board, were obtained from 247 older adults with a falls-related emergency department visit. Six-month prospective fall rate and habitual gait speed at 6 months post baseline assessment were also measured.\n\nRESULTS: In multivariable proportional odds analyses adjusted for potential confounders, falls efficacy modified the association between postural balance and fall risk (interaction P = 0.014): increasing falls efficacy accentuated the increased fall risk related to poor postural balance. Low baseline falls efficacy was strongly predictive of worse gait speed (0.11 m/s [0.06 to 0.16] slower gait speed per IQR decrease in MFES; P < 0.001).\n\nCONCLUSION: Older adults with high falls efficacy but poor postural balance were at greater risk for falls than those with low falls efficacy; however, low baseline falls efficacy was strongly associated with worse gait function at follow-up.

This study examined the cross-sectional associations between quadriceps force control, quadriceps activation, hamstring coactivation and clinically assessed knee function following anterior cruciate ligament reconstruction with a hamstring graft.\n\nMETHODS: Sixty-six patients (18 ± 3 months following surgery) and 41 uninjured individuals participated. Quadriceps force control was assessed using an isometric knee extension task. Participants cyclically increased and decreased quadriceps force at slow speeds between 5 and 30 % maximum voluntary isometric contraction matching a moving target displayed on a screen. Quadriceps activation and hamstring coactivation were assessed concurrently using surface electromyography. Knee function was assessed with the Cincinnati Knee Rating Scale and three single-leg hop tests.\n\nRESULTS: The reconstructed group completed the task with 48 % greater root-mean-square error (RMSE), indicating significantly worse quadriceps force control (p < 0.001). In a multivariable model adjusted for sex, greater RMSE and greater lateral hamstring coactivation were significantly associated with worse knee function that is greater odds of scoring <85 % on one or more knee functional assessment.\n\nCONCLUSIONS: Less-accurate quadriceps force output and greater hamstring coactivation are associated with worse knee joint function following anterior cruciate ligament reconstruction and may contribute to irregular knee joint loading and the onset or progression of knee osteoarthritis. Impairments in quadriceps force control and altered muscle activation strategies may be modifiable through neuromuscular training, and this is an area for future research.\n\nLEVEL OF EVIDENCE: Case-control study, Level III.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/26745965/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Luke Perraton", "Stacey Telianidis", "Adam L.

Centre of pressure (COP) path length, antero-posterior (AP) and medio-lateral (ML) sway range and slow and fast speed COP path-length were examined. Additional measures included single and triple hop distance and symmetry, knee flexion range of motion, ligament laxity and the International Knee Documentation Committee (IKDC) subjective knee evaluation form.\n\nRESULTS: No significant inter-limb balance differences were present in females. Significant, yet small to negligible effect size (ES) differences were present in males for ML range (ES=0.19), and AP and ML axis slow speed path length (ES=0.11 and 0.23 respectively).

The primary aim of this study was to examine the sensitivity to change and redundancy of center of pressure (COP) variables post-TKA.

Measures of COP standard deviation, amplitude, root mean square (RMS), path length, detrended fluctuation analysis (DFA) and signal frequency content for the medial-lateral (ML) and anterior-posterior (AP) axes were examined.\n\nRESULTS: Significant decreases in total path length, ML variables related to sway velocity and AP signal complexity and frequency were observed. Inter-session Cohen's d effect size (ES) revealed the strongest effect was for high velocity ML path length, with a 12% decrease in this rapid sway. This variable, along with AP mean instantaneous frequency and AP DFA, were the only ones significantly different with effect sizes >0.20 and non-redundant (Spearman's rho <0.75). The ES of COP-derived variables (maximum = 0.45) were lower than gait speed (1.40) and knee extensor strength (1.54).\n\nCONCLUSION: Increased high velocity ML sway is present at four compared to 12 weeks post-TKA.

Furthermore, functional stability of the knee joint depends on both adequate strength and the ability to produce force accurately. Previous studies assessing quadriceps force control following ACL injury have utilized constant sub-maximal isometric target forces. However, during most functional activities the quadriceps muscles are required to produce fluctuating force levels. Thus, the use of a testing protocol involving a cyclical or varying target force may better approximate quadriceps forces during functional activities. PURPOSE: To examine submaximal quadriceps force control in individuals with an ACL injury using a cyclical force target. METHODS: Eighteen (18) individuals (12M/6F; 29.8 ± 8.7years) within 8 months of unilateral isolated ACL injury (69.5 ± 42.5 days post-injury) and 18 healthy controls (12M/6F; 29.2 ± 6.8years) participated in the study. Participants performed an isometric quadriceps contraction to match an increasing force ramp from 5% to 25% body weight (BW), after which the ramp gradually reduced from 25% to 5% BW (0.10Hz). Four trials of 60s with 60s rest in between were performed. The root mean square error (RMSE) of quadriceps torque relative to target torque was determined, and compared between groups and limbs using a 2x2 ANOVA with repeated measures on limb. Sub-regional analysis assessed accuracy of force control over an increasing (ascending RMSE) and decreasing (descending RMSE) force ramp. RESULTS: There was significantly greater overall RMSE in both limbs of the ACL group compared to healthy controls (3.36 ± 1.8 %BW INV limb; 3.28 ± 1.2 %BW UNINV limb; 2.40 ± 0.61 %BW CONT; 2.40 ± 0.58 %BW UNINV CONT P=0.032). The ACL group had significantly higher descending RMSE in both limbs compared to healthy controls (3.92 ± 2.8 INV limb; 3.39 ± 1.6 UNINV limb; 2.43 ± 0.61 CONT; 2.36 ± 0.52 UNINV CONT P=0.035). Ascending RMSE did not differ between the ACL and control group limbs (P>0.05) CONCLUSIONS: There are significant bilateral deficits in submaximal quadriceps force control after ACL injury, compared to healthy controls, potentially contributing to altered knee function after ACL injury.", "abstractSource": "https://openalex.org/W2467064031", "type": "conference-abstract", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Sarah Ward", "Kim L.

Morris", "Ross A. Clark", "Adam L. Bryant", "John Olver"], "venue": "Journal of Physiotherapy", "abstract": "INTRODUCTION: Traumatic brain injury is the leading cause of disability in young adults aged 15 to 45 years. Mobility limitations are prevalent, and range in severity from interfering with basic day-to-day tasks to restricting participation in higher level social, leisure, employment and sporting activities. Despite the prevalence and severity of physical impairments, such as poor balance and spasticity, the main contributor to mobility limitations following traumatic brain injury is low muscle power generation. Strengthening exercises that are performed quickly are termed 'ballistic' as they are aimed at improving the rate of force production and, hence, muscle power. This is compared with conventional strength training, which is performed slowly and aims to improve maximum force production, yet has limited impact on mobility.\n\nRESEARCH QUESTION: In people recovering from traumatic brain injury: (1) is a 12-week ballistic strength-training program targeting the three muscle groups critical for walking more effective than usual care at improving mobility, strength and balance; and (2) does improved mobility translate to better health-related quality of life?\n\nDESIGN: A prospective, multi-centre, randomised, single-blind trial with concealed allocation will be conducted.\n\nPARTICIPANTS AND SETTING: Participants will be patients with a neurologically based movement disorder affecting mobility as a result of traumatic brain injury. Patients will be recruited during the acute phase of rehabilitation (n=166), from brain injury units in large metropolitan hospitals in Melbourne and Sydney, Australia.\n\nINTERVENTION: For 12 weeks, participants in the experimental group will have three 60-minute sessions of usual physiotherapy intervention replaced by three 60-minute sessions of strength training (ballistic strength, gait). The three key muscle groups responsible for forward propulsion will be targeted: ankle plantarflexors, hip flexors and the hip extensors. Initial loads will be low, to facilitate high contraction velocities. Progression to higher loads will occur only if participants can perform the exercises ballistically. The control group will have their three 60-minute sessions of usual physiotherapy intervention (balance, strength, stretch, cardiovascular fitness, gait) standardised so that all participants have equivalent therapy time. Both groups will continue to receive usual rehabilitation.\n\nOUTCOME MEASURES: The primary outcome will be mobility, measured using the High Level Mobility Assessment Tool. The secondary outcomes will be walking speed, muscle strength, balance and health-related quality of life. Walking speed will be measured using the 10-m walking test. Strength will be measured by a 6 repetition maximum, seated, single leg press test. Balance will be measured as the single limb support time. Health-related quality of life will be measured using the Assessment of Quality of Life. Outcomes will be measured at baseline (0 months), at completion of the intervention phase (3 months), and 3 months after cessation of intervention (6 months). Baseline measures will be completed prior to randomisation. Assessors blinded to group allocation will perform all measures.\n\nANALYSIS: Baseline characteristics of participants will be determined according to group, using descriptive statistics. The proportion of patients compliant with the intervention will be calculated according to group and compared using Fisher's exact test. Compliance with the intervention will be defined as those who have satisfactorily completed at least 80% of the allocated sessions (29 of 36 sessions). The between-group difference for all outcomes will be estimated using analysis of covariance, adjusting for baseline High Level Mobility Assessment Tool score, age, gender and length of post-traumatic amnesia. Analyses will be conducted on an intention-to-treat basis.\n\nDISCUSSION: Strength training in neurological rehabilitation is highly topical because muscle weakness has been identified as the primary impairment leading to mobility limitations in many neurological populations. This project represents the first international study of ballistic strength training after traumatic brain injury. The novelty of ballistic strength training is that the exercises attempt to replicate how lower limb muscles work, by targeting the high angular velocities attained during walking and higher level activities.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/27320832/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Gavin Williams", "Adam L.

However, to our knowledge, no studies have systematically integrated multiple predictors into a single, clinically practical model. Our study aimed to develop a prediction model to estimate the risk of post-TKA walking limitations.\n\nMETHODS: We performed a prospective cohort study of 1096 patients who underwent elective, primary TKA between July 2013 and September 2014. Candidate predictors included patient demographics, surgical factors, and pre- and early (1-mo) post-TKA functional measures. The outcome of interest was self-reported walking limitations at 6 months of post-TKA. We used multivariable proportional odds regression with bootstrap internal validation to develop the model.\n\nRESULTS: In all, 12% of patients reported walking limitations (maximum walk time ≤ 15 min) at 6 months postsurgery. The main predictors of increasing levels of walking limitations were preoperative walking limitations (overall p < 0.001), higher levels of body mass index [interquartile range (IQR)-OR 1.3, 95% CI 1.2-1.5], lower values of 1-month post-TKA gait speed (IQR-OR 1.9, 95% CI 1.3-2.6), the presence of contralateral knee pain (OR 1.9, 95% CI 1.2-3.0), and the use of a quadstick preoperatively (OR 3.5, 95% CI 1.7-7.3). The prediction model had an optimism-corrected concordance index of 0.71.\n\nCONCLUSION: A small but sizable proportion of patients with TKA had persistent mobility limitations. Our prediction model may help to risk-stratify patients, and external validation is required before the model can be used in clinical practice.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/26628603/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Felicia Jie‐Ting Seah", "Cheryl Lian-Li Poon", "John Wei-Ming Tan", "Hwei‐Chi Chong"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Yong‐Hao Pua", "Felicia Jie‐Ting Seah", "Cheryl Lian-Li Poon", "John Wei-Ming Tan", "Hwei‐Chi Chong"], "geo": {"city": "North Sydney", "geonames_city_id": "2154855", "region": "New South Wales", "country_code": "AU", "country": "Australia", "latitude": -33.839, "longitude": 151.2072}, "ror": "https://ror.org/04cxm4j25"}], "provenance": ["https://openalex.org/W2286084175", "https://pubmed.ncbi.nlm.nih.gov/26628603/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84969376972&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://www.jrheum.org/content/jrheum/43/2/419.full.pdf", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84969376972&origin=inward", "scopusDoi": "10.3899/jrheum.150724"}, {"id": "W2213377030", "title": "Does meniscal pathology alter gait knee biomechanics and strength post-ACL reconstruction?", "year": 2016, "doi": "10.1007/s00167-015-3908-x", "url": "https://doi.org/10.1007/s00167-015-3908-x", "authors": ["Michelle Hall", "Adam L.

Knee extensor weakness and altered dynamic knee joint biomechanics have been suggested to play a role in the development of knee OA following ACLR. This study investigated whether these factors differ in people following ACLR who have concomitant meniscal pathology compared to patients with isolated ACLR.\n\nMETHODS: Thirty-three patients with isolated ACLR and 34 patients with ACLR and meniscal pathology underwent strength and gait assessment 12-24 months post-operatively. Primary measures were peak isometric knee extensor torque and knee adduction moment (peak and impulse). Secondary measures included peak knee flexion moment and knee kinematics (sagittal and transverse).\n\nRESULTS: There were no between-group differences in knee extensor strength [mean difference (95 % CI) 0.09 (-0.23 to 0.42) Nm/kg, n.s.], peak knee adduction moment [-0.02 (-0.54 to 0.49) Nm/(BW × HT) %, n.s.] or knee adduction moment impulse [0.01 (-0.15 to 0.17) Nm/(BW × HT) %, p = n.s.]. No between-group differences were found for any secondary measures.\n\nCONCLUSIONS: No evidence was found to suggest that the higher prevalence of OA in patients with ACLR and meniscal pathology compared to patients with isolated ACLR is attributed to reduced knee muscle strength or altered knee joint biomechanics assessed 1-2 years post-surgery. Given that there is a higher incidence of knee OA in patients with concomitant meniscal pathology and ACLR, further investigation is needed so that population-specific rehabilitation protocols can be developed.\n\nLEVEL OF EVIDENCE: III.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/26667152/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Michelle Hall", "Adam L.

Background Postural control following anterior cruciate ligament reconstruction (ACLR) primarily has been investigated during static single-leg balance tasks. Little is known about dynamic postural control deficits post-ACLR. Objectives To compare dynamic postural control (bilaterally) in individuals who have undergone ACLR and in healthy controls, and to evaluate the relationship between dynamic postural control and self-reported and objective function. Methods Ninety-seven participants (66 male; median age, 28 years) 12 months post-ACLR and 48 healthy controls (20 male; median age, 30 years) underwent balance assessment using a Nintendo Wii Balance Board during a single-leg squat. Center-of-pressure (CoP) path velocity, as well as CoP amplitude and standard deviation, in both mediolateral (ML) and anteroposterior (AP) directions were recorded. Self-reported function was assessed with the International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC), while hop for distance was used to evaluate functional status. Results Compared to healthy controls, the ACLR group had greater mean CoP path velocity (16% higher, P = .004), ML range (23%, P<.001), ML SD (28%, P<.001), AP range (14%, P = .009), and AP SD (15%, P = .013), indicating worse dynamic balance post-ACLR. Dynamic balance performance was similar between the ACLR limb and the uninjured contralateral limb. The AP SD was weakly associated with hop performance (β = -.2, P = .046); no balance measures were associated with IKDC score. Conclusion Individuals who have undergone ACLR demonstrate impaired dynamic balance bilaterally when performing a single-leg squat, which may have implications for physical function and future injury risk. Routine dynamic balance assessment may help identify patients who could benefit from targeted neuromuscular training programs to improve objective function and potentially lower reinjury risk.

We hypothesized that children with traumatic brain injury would have significantly worse balance relative to children without brain injury.\n\nDESIGN: Prospective case-control pilot study.\n\nSETTING: Emergency department of a tertiary urban pediatric hospital.\n\nPARTICIPANTS: Cases were a convenience sample 11-16 years old who presented within 6 hours of sustaining concussion. Two controls, matched on gender, height, and age, were enrolled for each case that completed study procedures. Controls were children who presented for a minor complaint that was unlikely to affect balance.\n\nINTERVENTIONS: Not applicable.\n\nMAIN OUTCOME MEASURES: The participant's postural sway expressed as the displacement in centimeters of the center of pressure during a timed balance task. Balance testing was performed using 4 stances (single or double limb, eyes open or closed).\n\nRESULTS: Three of the 17 (17.6%) cases were too dizzy to complete testing. One stance, double limbs eyes open, was significantly higher in cases versus controls (85.6 vs 64.3 cm, P = 0.04).\n\nCONCLUSIONS: A simple test on the WBB consisting of a 2-legged standing balance task with eyes open discriminated children with concussion from non-head-injured controls. The low cost and feasibility of this device make it a potentially viable tool for assessing postural stability in children with concussion for both longitudinal research studies and clinical care.\n\nCLINICAL RELEVANCE: These pilot data suggest that the WBB is an inexpensive tool that can be used on the sideline or in the outpatient setting to objectively identify and quantify postural instability.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/26331470/", "type": "article", "institutions": [], "provenance": ["https://pubmed.ncbi.nlm.nih.gov/26331470/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84944345778&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84944345778&origin=inward", "scopusDoi": "10.1097/jsm.0000000000000234"}, {"id": "W2259216652", "title": "Methods of assessing associated reactions of the upper limb in stroke and traumatic brain injury: A systematic review", "year": 2016, "doi": "10.3109/02699052.2015.1117657", "url": "https://doi.org/10.3109/02699052.2015.1117657", "authors": ["Michelle Kahn", "Benjamin F.

Up to 15% of children born at < 30 weeks have cerebral palsy and an additional 50% have mild to severe motor impairment at school age. The first 5 years of life are critical for the development of fundamental motor skills. These skills form the basis for more complex skills that are required to competently and confidently participate in schooling, sporting and recreational activities. In children born at < 30 weeks' gestation, the trajectory of motor development from birth to 5 years is not fully understood. The neural alterations that underpin motor impairments in these children are also unclear. It is essential to determine if early clinical evaluations and neuroimaging biomarkers can predict later motor impairment and associated functional problems at 5 years of age. This will help to identify children who will benefit the most from early intervention and improve functional outcomes at school age.\n\nRESEARCH AIMS: The primary aim of this study is to compare the prevalence of motor impairment from birth to 5 years of age between children born at < 30 weeks and term-born controls, and to determine whether persistent abnormal motor assessments in the newborn period in those born at < 30 weeks predict abnormal motor functioning at 5 years of age. Secondary aims for children born at < 30 weeks and term-born children are: 1) to determine whether novel early magnetic resonance imaging-based structural or functional biomarkers that can predict motor impairments at 5 years are detectable in the neonatal period; 2) to investigate the association between motor impairments and concurrent deficits in body structure and function at 5 years of age; and 3) to explore how motor impairments at 5 years (including abnormalities of gait, postural control and strength) are associated with concurrent functional outcomes, including physical activity, cognitive ability, learning ability, and behavioural and emotional problems.\n\nDESIGN: Prospective longitudinal cohort study.\n\nPARTICIPANTS AND SETTING: 150 preterm children (born at < 30 weeks' gestation) and 151 term-born children (born at > 36 completed weeks' gestation and weighing > 2499g) admitted to the Royal Women's Hospital, Melbourne, were recruited at birth and will be invited to participate in a 5-year follow-up study.\n\nPROCEDURE: This study will examine previously collected data (from birth to 2 years) that comprise detailed motor assessments, and structural and functional brain MRI images. At 5 years, preterm and term, children will be examined using comprehensive motor assessments, including: the Movement Assessment Battery for Children (2nd edition) and measures of gait function through spatiotemporal (assessed with the GAITRite® Walkway) and dynamic postural control (assessed with Microsoft Kinect) variables; and hand grip strength (assessed with a dynamometer); and measures of physical activity (assessed using accelerometry), cognitive development (assessed with Wechsler Preschool and Primary Scale of Intelligence), and emotional and behavioural status (assessed with the Strengths and Difficulties Questionnaire and the Developmental and Wellbeing Assessment). At the 5-year assessment, parents/caregivers will be asked to complete questionnaires on demographics, physical activity, activities of daily living, behaviour, additional therapy (eg, physiotherapy and occupational therapy), and motor function (assessed with Pediatric Evaluation of Disability Inventory, Pediatric Quality of Life Questionnaire, the Little Developmental Co-ordination Questionnaire and an activity diary).\n\nANALYSIS: For the primary aim, the prevalence of motor impairment from birth to 5 years will be compared between children born at < 30 weeks and at term, using the proportion of children classified as abnormal at each of the time points (term age, 1, 2 and 5 years). Persistent motor impairments during the neonatal period will be assessed as a predictor of severity of motor impairment at 5 years of age in children born < 30 weeks using linear regression. Models will be fitted using generalised estimating equations to allow for the clustering of multiple births. Analysis will be repeated with adjustment for predictors of motor outcome, including additional therapy, sex, brain injury and chronic lung disease.\n\nDISCUSSION/SIGNIFICANCE: Understanding the developmental precursors of motor impairment in children born before 30 weeks is essential for limiting disruption to skill development, and potential secondary impacts on physical activity, participation, academic achievement, self-esteem and associated outcomes (such as obesity, poor physical fitness and social isolation). An improved understanding of motor skill development will enable targeting of interventions and streamlining of services to children at highest risk of motor impairments.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/27634166/", "type": "article", "institutions": [{"id": "https://openalex.org/I1321649718", "name": "Royal Children's Hospital", "country": "AU", "collaborators": ["Alicia J.

Methods: 104 lowlanders with COPD, GOLD 1-2, age 20-75 y, living near Bishkek (760 m), were randomized to receive either dexamethasone (2x4 mg/d p.o.) or placebo on the day before ascent and during a 3-day sojourn at Tuja-Ashu (3200 m), Kyrgyz Republic. Postural control was assessed at 760 m and one day after arrival at 3200 m by letting patients stand on a Wii Balance BoardTM recording the center of pressure path length (PL) during 5 trials of 30 s. Results: Ascending from 760 to 3200 m increased the PL in the placebo group from median (quartiles) 29.2 (25.8;38.2) to 31.5 (27.3;39.3) cm (P<0.04); in the dexamethasone group the change from 28.8 (22.8;34.5) to 29.9 (25.2;37.0) cm was nonsignificant (P=0.10). The mean difference between groups in altitude-induced PL change (treatment effect) was -0.3 cm (95% CI -3.2 to 2.5 cm, P=0.41). Regression analysis controlling for potential confounders confirmed an increase in PL at altitude (coefficient 1.6, 95% CI 0.16 to 30.8, P=0.03) but no effect of dexamethasone (coefficient 0.01, 95% CI -3.8 to 3.8, P=1.00). PL changes were related mostly to antero-posterior sway. 22 of 104 patients had an increase in antero-posterior sway velocity of >25%, what is associated with a two-fold risk of falls in previous studies (Kwok et al. Clin Biomech 2015). Conclusions: In lowlanders with COPD traveling to altitude (3200 m) postural control was impaired 24h after arriving and this was not prevented by dexamethasone.

Aim: To evaluate the relationship between postural balance and pulmonary hyperinflation in COPD patients. Methods: 67 patients were included (12% mild, 44% moderate and 44% severe COPD). Postural balance was evaluated by centre of pressure displacement analysis using a portable force platform in 3 different sensory conditions: standing with eyes open, eyes closed and on a foam surface with open eyes. The variables analysed included total path length, path velocity and amplitude, in both anteroposterior (AP) and mediolateral (ML) directions. Pulmonary hyperinflation was evaluated using body plethysmography. Participants were classified into 2 groups: hyperinflated (Total lung capacity >120% predicted) and non-hyperinflated. The Mann-Whitney-U-test was used for group comparison. Results: The hyperinflated patients (N=23; 64.8±9.7 yrs; FEV1 35.1±12.0% predicted) presented a smaller postural balance variation compared to non-hyperinflated patients (N=44; 67.5±8.8 yrs; FEV1 46.7±13.8% predicted) in the total path length (28.7±10.7cm vs. 32.8±8.3cm, p=0.02), in the amplitude (1.95±0.95cm vs. 2.26±0.87cm, p=0.016) and path velocity (0.74±0.26cm/s vs. 0.88±0.24cm/s, p=0.01), respectively, in the AP direction in the condition standing with eyes open.

Aim: To identify the relationship between clinical disease impact and postural balance in COPD patients. Methods: 68 patients were assessed for COPD assessment test (CAT) and postural balance by centre of pressure displacement analysis using a portable device in 3 conditions: standing with eyes open (EO), eyes closed (EC) and on a foam surface with open eyes. Outcomes for postural balance included amplitude (amp) (degree of movement to maintain balance) and path velocity (vel) in anteroposterior (AP) and mediolateral (ML) directions. Patients were divided according to CAT: low (n=9; 68±7yrs; FEV1 40±11%pred), medium (n=36; 69±10yrs; FEV1 43±16%pred) and high/very high impact (n=23; 64±9yrs; FEV1 42±13%pred). Kruskal-Wallis and Dunn9s tests were used to compare groups. Results: Groups were similar in age and severity of disease. Patients with high/very high clinical impact presented greater variation in the APamp with EO (2.5±1.0, 1.8±0.4, 2.0±0.8cm;p=0.02) and in the MLamp with EC (1.9±1.6, 1.0±0.4, 1.3±0.7cm;p=0.01) compared to low but not to medium, respectively.

Squat performance was captured using video. Video footage was uploaded and reformatted for analyses. Hip muscle strength was measured with handheld dynamometry using reliable methods.\n\nOUTCOME MEASURES: Frontal plane pelvic obliquity, hip adduction, and knee valgus were measured. Repeated measures analysis of variance evaluated between-group differences, with limb as a within-subjects factor (surgical versus nonsurgical) and gender as a between-subjects factor (P < .05).\n\nRESULTS: The hip arthroscopy group demonstrated significantly greater apparent hip adduction (mean difference 2.7°, 95% confidence interval [CI] 0.7°-4.8°) and apparent knee valgus (4.0°, 95% CI 1.0°-7.1°) at peak squat depth compared with control subjects. The operated limb also demonstrated significantly greater pelvic obliquity during single-leg stance compared with the nonsurgical limb (1.2°, 95% CI 0.1°-2.3°).

A systematic review was completed in order to compare the biomechanics of gait, closed kinetic chain and plyometric exercise when performed in water and on land.\n\nMETHODS: Databases including MEDLINE, CINAHL, SPORTDiscus, Embase and the Cochrane library were searched. Studies were included where a functional lower limb activity was performed in water and on land with the same instructions. Standardized mean differences (SMD) and 95% confidence intervals were calculated for spatiotemporal, kinematic, force and muscle activation outcomes.\n\nFINDINGS: 28 studies included walking or running (19 studies), stationary running (three), closed kinetic chain exercise (two), plyometric exercise (three) and timed-up and go (one). Very large effect sizes showed self-selected speed of walking (SMD >4.66) and vertical ground reaction forces (VGRF) (SMD >1.91) in water were less than on land, however, lower limb range of movement and muscle activity were similar. VGRF in plyometric exercise was lower in water when landing but more similar between the two environments in propulsion. Maximal speed of movement for walking and stationary running was lower in water compared to on land (SMD>3.05), however was similar in propulsion in plyometric exercise.\n\nINTERPRETATION: Drag forces may contribute to lower self-selected speed of walking.

Rate of force development (RFD) is often used for muscle power assessment, however no consensus currently exists on the most appropriate method of calculation. The aim of this study was to examine the reliability of different algorithms for RFD calculation and to examine the intra-rater, inter-rater, and inter-device reliability of HHD as well as the concurrent validity of HHD for the assessment of isometric lower limb muscle strength and power.\n\nMETHODS: 30 healthy young adults (age: 23±5 yrs, male: 15) were assessed on two sessions. Isometric muscle strength and power were measured using peak force and RFD respectively using two HHDs (Lafayette Model-01165 and Hoggan microFET2) and a criterion-reference KinCom dynamometer. Statistical analysis of reliability and validity comprised intraclass correlation coefficients (ICC), Pearson correlations, concordance correlations, standard error of measurement, and minimal detectable change.\n\nRESULTS: Comparison of RFD methods revealed that a peak 200 ms moving window algorithm provided optimal reliability results. Intra-rater, inter-rater, and inter-device reliability analysis of peak force and RFD revealed mostly good to excellent reliability (coefficients ≥ 0.70) for all muscle groups. Concurrent validity analysis showed moderate to excellent relationships between HHD and fixed dynamometry for the hip and knee (ICCs ≥ 0.70) for both peak force and RFD, with mostly poor to good results shown for the ankle muscles (ICCs = 0.31-0.79).\n\nCONCLUSIONS: Hand-held dynamometry has good to excellent reliability and validity for most measures of isometric lower limb strength and power in a healthy population, particularly for proximal muscle groups. To aid implementation we have created freely available software to extract these variables from data stored on the Lafayette device. Future research should examine the reliability and validity of these variables in clinical populations.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/26509265/", "type": "article", "institutions": [{"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Benjamin F.

Targeted searching of reference lists of included articles and three relevant journals was also performed. Two independent reviewers identified relevant articles, extracted data and assessed the methodological quality of included articles. Inclusion criteria involved studies that assessed univariate correlations between gait velocity and isometric strength of individual lower limb muscle groups in a stroke population.\n\nRESULTS: Twenty-one studies were included for review. The majority of included studies had a relatively small sample size. After accounting for sample size and methodological quality, the knee extensors showed poor-to-moderate correlations with gait velocity while the ankle dorsiflexors showed the strongest association with gait velocity.\n\nCONCLUSIONS: Current evidence suggests that the strength of the ankle dorsiflexors has a stronger correlation to gait velocity compared with other lower limb muscle groups. Consequently, a focus on increasing ankle dorsiflexor strength to improve gait velocity following stroke may be beneficial.

METHODS: 48 community-dwelling older adults aged ⋝65 years (mean 71.6±4.8 years; 52% women) underwent whole-body dual-energy X-ray absorptiometry, to assess appendicular lean mass (ALM), and peripheral quantitative computed tomography (pQCT; 66% tibia), to assess calf IMAT cross-sectional area ([CSA]; cm2) and muscle density (mg/cm(3); higher values indicate lower fat infiltration). Fasting glucose, lipids, triglycerides and C-reactive protein (CRP) were analysed. Physical function was assessed by postural sway (computerised posturography; N=41), and gait analysis (GAITRite Electronic Walkway; N=40). RESULTS: Higher IMAT CSA and muscle density were associated with significantly higher (B=0.85 95%CI [0.34, 1.36]) and lower (-2.14 [-4.20, -0.08]) CRP and higher (0.93 [0.56, 1.30]) and lower postural sway (-3.12 [-4.74, -1.50]), respectively, after adjustment for age, sex and ALM/BMI. Higher IMAT CSA was associated with slower gait speed and cadence, and greater step time and step width (all P<0.03), while higher muscle density was associated with smaller step width (P<0.01) only.

This cross-sectional study aimed to evaluate, in patients with ACLD, the independent impact of isokinetic quadriceps and hamstrings torque steadiness on single-leg hop performance.\n\nMETHODS: Eighty-seven patients with unilateral ACLD participated. Patients performed isokinetic quadriceps and hamstrings steadiness and strength testing at 60°/s on an isokinetic dynamometer. Muscle steadiness and strength were represented by the wavelet-derived mean instantaneous frequency and peak value of the torque-time curves, respectively. To measure hop performance, patients performed a single-leg hop for distance and a 6-m single-leg hop for velocity.\n\nRESULTS: One of two patients [n = 45 (51 %)] had a 10 % or greater difference in knee torque frequency levels between the ACLD and contralateral knees. In multivariable models adjusted for age, sex, knee pain, and knee strength, hamstrings steadiness was significantly related with hop velocity whilst quadriceps steadiness was significantly related with both hop distance and velocity. Variance decomposition analyses suggested that quadriceps steadiness was similar in importance to hamstrings strength on hop distance and velocity.\n\nCONCLUSIONS: In patients with ACLD, isokinetic knee steadiness deficits were common and were independently associated with single-leg hop performance. Knee torque steadiness-a heretofore understudied variable-may prove a useful adjunct to conventional peak torque measurements by offering additional information to researchers and rehabilitation professionals about muscle performance and neuromuscular knee control.\n\nLEVEL OF EVIDENCE: Prognostic studies, Level III.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/24756538/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua", "Peck‐Hoon Ong", "Jia-Ying Ho"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

A multivariable proportional odds prediction model was constructed using 8 pre-specified predictors – namely, age, sex, body mass index, knee pain, knee range-of-motion, active knee lag, and WBB-derived standing balance. The type of walking aids prescribed on day 4 post-surgery was the outcome of interest – an ordinal variable with 4 categories (walking stick, narrow- and broad-base quadstick, and walking frame).\n\nRESULTS: Women, increasing body mass index, and poorer standing balance were independently associated with greater odds for requiring walking aids with a larger base-of-support. The concordance-index of the prediction model was 0.74. The model comprising only WBB-derived standing balance had nearly half (44%) the explanatory power of the full model. Adding WBB-derived standing balance to conventional demographic and knee variables resulted in a continuous net reclassification index of 0.60 (95%CI,0.19-1.01), predominantly due to better identification of patients who required walking aids with a large base-of-support (sensitivity gain).\n\nCONCLUSIONS: The WBB was able to provide quantitative measures of standing balance which could assist healthcare professionals in prescribing the appropriate type of walking aids for patients.

This study examined the concurrent validity and inter-day reliability of spatiotemporal and kinematic gait parameters estimated using the Kinect V2 automated body tracking system and a criterion reference three-dimensional motion analysis (3DMA) marker-based camera system. Thirty healthy adults performed two testing sessions consisting of comfortable and fast paced walking trials. Spatiotemporal outcome measures related to gait speed, speed variability, step length, width and time, foot swing velocity and medial-lateral and vertical pelvis displacement were examined. Kinematic outcome measures including ankle flexion, knee flexion and adduction and hip flexion were examined. To assess the agreement between Kinect and 3DMA systems, Bland-Altman plots, relative agreement (Pearson's correlation) and overall agreement (concordance correlation coefficients) were determined. Reliability was assessed using intraclass correlation coefficients, Cronbach's alpha and standard error of measurement. The spatiotemporal measurements had consistently excellent (r≥0.75) concurrent validity, with the exception of modest validity for medial-lateral pelvis sway (r=0.45-0.46) and fast paced gait speed variability (r=0.73). In contrast kinematic validity was consistently poor to modest, with all associations between the systems weak (r<0.50). In those measures with acceptable validity, the inter-day reliability was similar between systems. In conclusion, while the Kinect V2 body tracking may not accurately obtain lower body kinematic data, it shows great potential as a tool for measuring spatiotemporal aspects of gait.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/26065332/", "type": "article", "institutions": [{"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Benjamin F.

We tested whether exposure to hypobaric hypoxia at moderate altitude impairs the static postural control of healthy subjects.\n\nMETHODS: In 51 healthy men, median age 24 y (quartiles 20;28), static control was evaluated on a balance platform in Zurich, 490 m, and during a 4-day sojourn in Swiss mountain villages at 1630 m and 2590 m, 2 days each. The order of altitude exposure was randomized. Total center of pressure path length (COPL) and sway amplitude measured in two directions by a balance platform, and pulse oximetry were recorded. Data were compared between altitudes.\n\nRESULTS: Median (quartiles) COPL during standing on both legs with eyes open at 490 m and in the evenings on the first and second days at 1630 and 2590 m, respectively were: 50 (45;57), 55 (48;62), 56 (49;61), 53 (47;59), 54 (48;60) cm, P<0.001 ANOVA. Corresponding arterial oxygen saturation was 97% (96;97), 95% (94;96), 95%(94;96), 92%(90;93), 93%(91;93), P<0.001. Anterior-posterior sway amplitudes were larger at 1630 and 2590 m compared to 490 m, P<0.001. Multiple logistic regression analysis confirmed that higher altitudes (1630 and 2590m) were independently associated with increased COPL when controlled for the order of altitude exposure and age (P=0.001).\n\nCONCLUSIONS: Exposure to 1630 and 2590m was associated with impaired static postural control even when visual references were available.\n\nTRIAL REGISTRATION: ClinicalTrials.gov NCT01130948.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/25723529/", "type": "article", "institutions": [{"id": "https://openalex.org/I202697423", "name": "University of Zurich", "country": "CH", "collaborators": ["Katrin Stadelmann", "Reto Huber", "Malcolm Kohler", "Peter Achermann", "Konrad E.

This study examined the reliability and additional information that the Kinect provides when instrumenting a gait assessment in people living with stroke.\n\nMETHODS: The spatiotemporal variables of step length, step length asymmetry, foot swing velocity, foot swing velocity asymmetry, peak and mean gait speed and the percentage difference between the peak and mean gait speed were assessed during gait trials in 30 outpatients more than three months post-stroke and able to stand unsupported. Additional clinical assessments of functional reach (FR), step test (ST), 10 m walk test (10MWT) and the timed up and go (TUG) were performed, along with force platform instrumented assessments of center of pressure path length velocity during double-legged standing balance with eyes closed (DLEC), weight bearing asymmetry (WBA) and dynamic medial-lateral weight-shifting ability (MLWS). These tests were performed on two separate occasions, seven days apart for reliability assessment. Separate adjusted multiple regressions models for predicting scores on the clinical and force platform assessments were created using 1) the easily assessed clinically-derived gait variables 10MWT time and total number of steps; and 2) the Kinect-derived variables which were found to be reliable (ICC > 0.75) and not strongly correlated (Spearman's ρ < 0.80) with each other (i.e. non-redundant).\n\nRESULTS: Kinect-derived variables were found to be highly reliable (all ICCs > 0.80), but many were redundant. The final regression model using Kinect-derived variables consisted of the asymmetry scores, mean gait velocity, affected limb foot swing velocity and the difference between peak and mean gait velocity. In comparison with the clinically-derived regression model, the Kinect-derived model accounted for >15% more variance on the MLWS, ST and FR tests and scored similarly on all other measures.\n\nCONCLUSIONS: In conclusion, instrumenting gait using the Kinect is reliable and provides insight into the dynamic balance capacity of people living with stroke.

Repeated testing was completed within 7 days. Participants performed strength testing in sitting using a wooden platform in combination with the NWBB. This new method was set up to selectively recruit an intrinsic muscle of the foot, specifically the flexor hallucis brevis muscle. Statistical analysis was performed using intra-class coefficients and ordinary least product analysis. To estimate measurement error, standard error of measurement (SEM), minimal detectable change (MDC) and percentage error were calculated.\n\nRESULTS: Results indicate excellent intra-rater reliability (ICC = 0.982, CI = 0.96-0.99) with an absence of systematic bias. SEM, MDC and percentage error value were 0.5, 1.4 and 12 % respectively.\n\nCONCLUSIONS: This study demonstrates that a new method in combination with the NWBB application is reliable to measure hallux flexor strength and has potential to be used for future research and clinical application.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/26355671/", "type": "article", "institutions": [{"id": "https://openalex.org/I165143802", "name": "The University of Queensland", "country": "AU", "collaborators": ["June Quek", "Julia Treleaven", "Sandra Brauer", "Shaun O’Leary"], "geo": {"city": "Brisbane", "geonames_city_id": "2174003", "region": "Queensland", "country_code": "AU", "country": "Australia", "latitude": -27.46794, "longitude": 153.02809}, "ror": "https://ror.org/00rqy9422"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["June Quek", "Julia Treleaven", "Sandra Brauer"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I2799393793", "name": "Royal Brisbane and Women's Hospital", "country": "AU", "collaborators": ["Shaun O’Leary"], "geo": {"city": "Brisbane", "geonames_city_id": "2174003", "region": "Queensland", "country_code": "AU", "country": "Australia", "latitude": -27.46794, "longitude": 153.02809}, "ror": "https://ror.org/05p52kj31"}], "provenance": ["https://openalex.org/W2137428386", "https://pubmed.ncbi.nlm.nih.gov/26355671/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84941092389&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://onlinelibrary.wiley.com/doi/pdfdirect/10.1186/s13047-015-0104-7", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84941092389&origin=inward", "scopusDoi": "10.1186/s13047-015-0104-7"}, {"id": "W1967258152", "title": "Lower limb kinematics and physiological responses to prolonged load carriage in untrained individuals", "year": 2015, "doi": "10.1080/00140139.2014.984775", "url": "https://doi.org/10.1080/00140139.2014.984775", "authors": ["Alexandra K.

This exploratory study investigated the use of the Wii Balance Board and other clinical-based measures for prospectively predicting falls among community-dwelling older adults.\n\nMETHODS: Seventy-three community-dwelling men and women, aged 60-85years were followed-up over a year for falls. Standing balance was indexed by sway velocities measured using the Wii Balance Board interfaced with a laptop. Clinical-based measures included Short Physical Performance Battery, gait speed and Timed-Up-and-Go test. Multivariable regression analyses were used to assess the ability of the Wii Balance Board measure to complement the TUG test in fall screening.\n\nFINDINGS: Individually, the study found Wii Balance Board anteroposterior (odds ratio 1.98, 95% CI 1.16 to 3.40, P=0.01) and mediolateral (odds ratio 2.80, 95% CI 1.10 to 7.13, p=0.03) sway velocity measures predictive of prospective falls. However, when each velocity measure was adjusted with body mass index and Timed-Up-and-Go, only anteroposterior sway velocity was predictive of prospective falls (odds ratio 2.21, 95% CI 1.18 to 4.14). A faster anteroposterior velocity was associated with increased odds of falling. Area-under-the-curves for Wii Balance Board sway velocities were 0.67 and 0.71 for anteroposterior and mediolateral respectively.\n\nINTERPRETATION: The Wii Balance Board-derived anteroposterior sway velocity measure could complement existing clinical-based measures in predicting future falls among community-dwelling older adults.\n\nTRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry number: ACTRN12610001099011.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/25796535/", "type": "article", "institutions": [{"id": "https://openalex.org/I4210109428", "name": "National Pension Service", "country": "KR", "collaborators": ["Boon-Chong Kwok"], "geo": {"city": "Seoul", "geonames_city_id": "1835848", "region": null, "country_code": "KR", "country": "South Korea", "latitude": 37.561790466308594, "longitude": 126.98885345458984}, "ror": "https://ror.org/021j14906"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}], "provenance": ["https://openalex.org/W1966954072", "https://pubmed.ncbi.nlm.nih.gov/25796535/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84929272047&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84929272047&origin=inward", "scopusDoi": "10.1016/j.clinbiomech.2015.03.006"}, {"id": "W2043374528", "title": "Postural control at 4 years in very preterm children compared with term‐born peers", "year": 2015, "doi": "10.1111/dmcn.12550", "url": "https://doi.org/10.1111/dmcn.12550", "authors": ["Lucy E Lorefice", "Mary P.

Limitations of static clinical assessments may be overcome through advances in technologies, including commercially available depth cameras.\n\nMETHODS: The Foot Posture Index (FPI) of 31 males (average age, 22.5 years) was assessed using visual observation, a 3-D motion-analysis system, and a depth camera. Pearson correlations were used to evaluate relationships between FPI items and rearfoot and midfoot kinematics during walking. The ability of the static variables to predict dynamic function was assessed using multiple linear regression.\n\nRESULTS: Most FPI items (85%) were not correlated with foot kinematics, regardless of assessment method. There were 6 fair to moderate correlations between visual FPI items and total rearfoot (r = -0.36 to -0.39, P<.05) and midfoot (r = 0.37 to 0.61, P<.05) motion, 2 fair correlations between 3-D motion-analysis FPI items and total midfoot (r = -0.43, P = .02) and peak rearfoot (r = -0.40, P = .03) motion, and 2 fair correlations between the depth-camera FPI items and average rearfoot (r = -0.38 to 0.44, P<.05) motion. Visual assessment of the FPI provided the best prediction model, explaining 37% of the variance in total midfoot inversion/eversion.\n\nCONCLUSION: Static measures of foot posture are weakly correlated with rearfoot or midfoot kinematics, and have limited dynamic prediction ability.

The Microsoft Kinect presents a simple, inexpensive, and portable method of examining the independent components of the Timed Up and Go (TUG) without any intrusion on the patient. Objective. This study examined the reliability of these measures, and whether they improved prediction of performance on common clinical tests. Methods. Thirty individuals with stroke completed 4 clinical assessments, including the TUG, 10-m walk test (10MWT), Step Test, and Functional Reach test on 2 testing occasions. The TUG was assessed using the Kinect to determine 7 different functional components. Test-retest reliability was assessed using intraclass correlation coefficient (ICC), redundancy using Spearman's correlation, and score prediction on the clinical tests using multiple regression. Results. All Kinect-TUG variables possessed excellent reliability (ICC(2,k) > 0.90) except trunk flexion angle (ICC = 0.73). Trunk flexion angle and first step length were nonredundant with total TUG time. When predicting 10MWT and Step Test scores, adding step length into regression models comprising age and total TUG time improved model performance by 7% (P <.01) and 6% (P =.03), respectively. Specifically, an interquartile range increase in first step length (0.19 m) was associated with a 0.15 m/s faster gait speed and 1.8 more repetitions on the Step Test. These effect sizes were comparable to our minimal detectable change scores of 0.17 m/s for gait speed and 1.71 repetitions for the Step Test. Conclusions. Using the Kinect to independently assess the multiple components of the TUG may provide reliable and clinically useful information. This could enable efficient and information-rich large-scale assessments of physical deficits following stroke.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/24743227/", "type": "article", "institutions": [{"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Stephanie Vernon"], "geo": {"city": "North Sydney", "geonames_city_id": "2154855", "region": "New South Wales", "country_code": "AU", "country": "Australia", "latitude": -33.839, "longitude": 151.2072}, "ror": "https://ror.org/04cxm4j25"}, {"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kade L.

It is of clinical relevance to characterize motor representation areas of muscles in healthy individuals to allow researchers to quantify the extent of changes seen in pathological populations Purpose: The purpose of this study was to determine the size and center of the rectus femoris motor area in healthy individuals. METHODS: Ten healthy subjects (5M/5F) aged 27.3±6.46 years had the motor representation of the rectus femoris muscle of both limbs determined using TMS. Subjects attended two 45min testing sessions, an average 17d apart. Active motor threshold (AMT) was established at ∼10% maximum contraction with mapping stimulus intensity adjusted at 120% AMT. Four stimuli were given 5s apart while participant contracted rectus femoris at ∼10% of max, starting at the identified optimal site and then moving in 2cm steps in anterior, then posterior directions until a MEP could no longer be elicited. This pattern was repeated for lateral, then medial sites (1cm steps) until all map borders had been determined. Paired t-tests (P<0.05) were used to assess symmetry. RESULTS: No significant difference in AMT were found between hemispheres (55.6±6.85% RH vs 52.2±6.49% LH, P=0.101).The mean AP-CoG position in the RH was 0.15±0.54cm anterior from the vertex, and 0.20±0.67cm anterior in the LH. The mean ML-CoG position in the RH was 2.35±0.62cm lateral from the vertex, and 2.45±0.52cm lateral in the LH. There were no significant differences between hemispheres (AP-CoG P=0.760, and ML-CoG P=0.257). Surface area representation at 66% of map MEP amplitude was 5.92±4.78cm for the RH and 8.24±8.63cm for the LH. No significant differences were found between hemispheres (P=0.130).

This study assesses the reliability and validity of a custom Smartphone application for assessing hip joint range of motion.\n\nDESIGN: Intra-tester reliability with concurrent validity.\n\nMETHODS: Passive hip joint range of motion was recorded for seven different movements in 20 males on two separate occasions. Data from a Smartphone, bubble inclinometer and a three dimensional motion analysis (3DMA) system were collected simultaneously. Intraclass correlation coefficients (ICCs), coefficients of variation (CV) and standard error of measurement (SEM) were used to assess reliability. To assess validity of the Smartphone application and the bubble inclinometer against the three dimensional motion analysis system, intraclass correlation coefficients and fixed and proportional biases were used.\n\nRESULTS: The Smartphone demonstrated good to excellent reliability (ICCs>0.75) for four out of the seven movements, and moderate to good reliability for the remaining three movements (ICC=0.63-0.68). Additionally, the Smartphone application displayed comparable reliability to the bubble inclinometer. The Smartphone application displayed excellent validity when compared to the three dimensional motion analysis system for all movements (ICCs>0.88) except one, which displayed moderate to good validity (ICC=0.71).\n\nCONCLUSIONS: Smartphones are portable and widely available tools that are mostly reliable and valid for assessing passive hip range of motion, with potential for large-scale use when a bubble inclinometer is not available.

The aim of this study was to assess the concurrent validity and reliability of kinematic data recorded using a marker-based three dimensional motion analysis (3DMA) system and the Kinect V2 during a variety of static and dynamic balance assessments. Thirty healthy adults performed two sessions, separated by one week, consisting of static standing balance tests under different visual (eyes open vs. closed) and supportive (single limb vs. double limb) conditions, and dynamic balance tests consisting of forward and lateral reach and an assessment of limits of stability. Marker coordinate and joint angle data were concurrently recorded using the Kinect V2 skeletal tracking algorithm and the 3DMA system. Task-specific outcome measures from each system on Day 1 and 2 were compared. Concurrent validity of trunk angle data during the dynamic tasks and anterior-posterior range and path length in the static balance tasks was excellent (Pearson's r>0.75). In contrast, concurrent validity for medial-lateral range and path length was poor to modest for all trials except single leg eyes closed balance. Within device test-retest reliability was variable; however, the results were generally comparable between devices.

Lower limb kinematic, kinetic and ground reaction force (GRF) data were collected during double-leg squats at baseline and after a generalised fatigue protocol. Symmetry indices were calculated for hip and knee external flexion moments and the vertical GRF (weight-bearing symmetry) at maximum squat depth. These were compared between ACLR and control groups before and after fatigue using ANOVA models.\n\nRESULTS: The ACL group preferentially unloaded the reconstructed limb at baseline, but changed to a more symmetrical load distribution to perform the squat exercise in the fatigue condition. This same loading pattern was seen at both the knee and hip joints. The control group did not show any effect of fatigue. For both groups, symmetry indices were closer to zero (which indicated perfect symmetry) in the fatigue condition.\n\nCONCLUSIONS: When prescribing squat exercises, it should be recognised that initially, patients with ACLR tend to unload the affected knee. More symmetrical loading patterns may be achieved by inducing bilateral fatigue. When fatigued, loading symmetry was similar between this patient group and controls. This is relevant information for those who implement rehabilitation training programmes.\n\nLEVEL OF EVIDENCE: III.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/24934927/", "type": "article", "institutions": [{"id": "https://openalex.org/I196829312", "name": "La Trobe University", "country": "AU", "collaborators": ["Kate E.

Nineteen subjects performed single-legged hopping manoeuvres and subject-specific musculoskeletal models were developed to predict muscle forces during the movement. Muscle forces were predicted using static optimisation (SO) and computed muscle control (CMC) methods using either 1 or 3 DOF knee joint models. All sagittal and transverse plane joint angles calculated using inverse kinematics or CMC in a 1 DOF or 3 DOF knee were well-matched (RMS error<3°). Biarticular muscles (hamstrings, rectus femoris and gastrocnemius) showed more differences in muscle force profiles when comparing between the different muscle prediction approaches where these muscles showed larger time delays for many of the comparisons. The muscle force magnitudes of vasti, gluteus maximus and gluteus medius were not greatly influenced by the choice of muscle force prediction method with low normalised root mean squared errors (<48%) observed in most comparisons. We conclude that SO and CMC can be used to predict lower-limb muscle co-contraction during hopping movements. However, care must be taken in interpreting the magnitude of force predicted in the biarticular muscles and the soleus, especially when using a 1 DOF knee. Despite this limitation, given that SO is a more robust and computationally efficient method for predicting muscle forces than CMC, we suggest that SO can be used in conjunction with musculoskeletal models that have a 1 or 3 DOF knee joint to study the relative differences and the role of muscles during hopping activities in future studies.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/25129166/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Hossein Mokhtarzadeh", "Luke Perraton", "Laurence A.

This study used a body-worn global positioning system (GPS) device to determine the outdoor activity per day performed by this population. Additionally, this study examined the association that mobility, time since injury and injury severity had with levels of outdoor physical activity.\n\nFINDINGS: Seventeen people with TBI and 15 control subjects wore a GPS device for between 3-7 days to monitor their outdoor activity. Based on the individual's location and speed of movement the outdoor physical activity in minutes per day was derived. Assessments of duration of outdoor activity between groups, and the relationship that duration of outdoor activity had with results on the high-level mobility assessment tool, length of post-traumatic amnesia, and time since injury were performed. No significant (p = 0.153, effect size = 0.26) difference in time spent in outdoor physical activity was observed between the TBI (median[IQR] = 19[3-43]mins) and control (median[IQR] = 50[18-65]mins) group. Interestingly, 35% of TBI subjects performed <10 mins of outdoor activity per day compared to 13% of the control group. The TBI group also recorded three of the four highest values for outdoor physical activity. Higher levels of mobility were associated with more outdoor activity (Spearman's rho = 0.443, p = 0.038). No other significant associations were observed.\n\nCONCLUSIONS: While preliminary, our results indicate that a sub-group of people with TBI exists who restrict their outdoor activities.

Ninety subjects, 45 who had undergone ACLR and 45 matched controls, performed single leg static standing balance tests on their surgical or matched limb on a Nintendo Wii Balance Board. Data were analysed in the anterior-posterior axis of movement, which is known to be affected by ACLR. The traditional measures of path velocity, amplitude and standard deviation were calculated in this plane. Additionally, sample entropy and discrete wavelet transform derived assessment of path velocity in four distinct frequency bands related to (1) spinal reflexive loops and muscle activity, (2) cerebellar, (3) vestibular, and (4) visual mechanisms of postural control were derived. The ACLR group had significantly increased values in all traditional measures and all four frequency bands. No significant difference was observed for sample entropy. This indicated that whilst postural sway was amplified in the ACLR group, the overall mechanism used by the patient group to maintain balance was similar to that of the control group.

The objective of this study was to better understand the physical function characteristics of women with osteoporosis, with and without a previous history of falls, by further stratifying them based on their single-leg stance (SLS) performance. Eighty-seven consecutive, community-dwelling women with osteoporosis were recruited from the Endocrinology Clinic at Singapore General Hospital.

Fallers and non-fallers did not differ in standing balance, lower limb strength nor the 6MWT (P's>0.08). SLS performance was an independent predictor of the various functional measures, after adjusting for age and body mass index. Specifically, an increase in SLS time was associated with lower standing center-of-pressure velocities, greater lower limb strength, and greater 6-min walking distance. When the two groups were stratified based on their recent history of falls and clinic-based standing balance performance (SLS time), fallers with good SLS time (>30 s) showed better functional outcomes than did non-fallers with poor SLS time (≤30 s) (P's<0.08) and comparable functional outcomes with non-fallers with good SLS time (P's>0.11).

This study aimed to determine whether people with hip chondropathy demonstrated impaired balance ability during a dynamic single-leg squat with eyes open (SquatEO) and a single-leg standing task with eyes closed (StandEC) and whether hip range of motion (ROM) and hip muscle strength were correlated with balance measures in adults with hip chondropathy.\n\nMETHODS: Sixty-three adults with hip chondropathy and 60 controls performed 2 tasks: SquatEO and StandEC while standing on a Nintendo Wii Balance Board. Center of pressure (COP) movement in mediolateral and anteroposterior directions was extracted. Hip ROM and muscle strength were measured with an inclinometer and dynamometer. Data were analyzed using an analysis of covariance and stepwise multiple regression model.\n\nRESULTS: During SquatEO, greater COP mediolateral range (P = 0.023) and anteroposterior SD (P = 0.043) were observed in those with hip chondropathy compared to controls. No significant between-group differences were observed for StandEC. Hip external rotation ROM was significantly associated with mediolateral range during SquatEO.\n\nCONCLUSION: Dynamic single-leg balance squat performance is reduced in people with hip chondropathy compared to healthy adults, but static single-leg standing balance is not. This may be reflective of reduced control of dynamic movements. Those with greater hip joint external rotation ROM appear to have worse single-leg squat balance performance.

Participants performed standardised assessments incorporating the WBB and customised software (static stance with eyes open and closed, static weight-bearing asymmetry, dynamic mediolateral weight shifting and dynamic sit-to-stand) in addition to commonly employed clinical tests (10 Metre Walk Test, Timed Up and Go, Step Test and Functional Reach) on two testing occasions one week apart. Test-retest reliability and construct validity of the WBB tests were investigated.\n\nRESULTS: All WBB-based outcomes were found to be highly reliable between testing occasions (ICC = 0.82 to 0.98). Correlations were poor to moderate between WBB variables and clinical tests, with the strongest associations observed between task-related activities, such as WBB mediolateral weight shifting and the Step Test.\n\nCONCLUSIONS: The WBB, used with customised software, is a reliable and potentially useful tool for the assessment of balance and weight-bearing asymmetry following stroke. Future research is recommended to further investigate validity and responsiveness.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/25541939/", "type": "article", "institutions": [{"id": "https://openalex.org/I1320473756", "name": "The Royal Melbourne Hospital", "country": "AU", "collaborators": ["Kelly J.

Although neck musculature fatigue has been demonstrated to impair standing balance, there is limited understanding of the underlying postural mechanisms. This study aimed to further examine the effects of neck musculature fatigue on standing by using modern analysis of center of pressure (CoP) data. Forty-eight young healthy adults stood quietly on a balance board for 1 min before and after performing repeated weight-resisted scapular elevation exercises. In a supplementary study on 20 participants, we examined (i) the effects of visual deprivation and (ii) the test-retest reliability of the traditional and wavelet-based CoP measures. Test-retest reliability of the CoP measures was moderate to good (intraclass correlation coefficients ranged from 0.58 to 0.94). With neck muscle fatigue or without vision, traditional measures of CoP velocity and standard deviation increased monotonically. Wavelet analysis revealed that CoP velocity within the ultralow (<0.10 Hz) and moderate (1.56-6.25 Hz) frequency bands increased post-fatigue. Without vision, CoP velocity increased in all but the ultralow frequency band. Our data suggest that post-fatigue, vision may be the main compensatory postural mechanism for altered neck proprioception.

The aim of this study was to explore standing postural control mechanisms in older adults with neck pain (NP) using measures of signal frequency (wavelet analysis) and complexity (entropy). This cross-sectional study compared balance performance of twenty older adults with (age=70.3±4.0 years) and without (age=71.4±5.1 years) NP when standing on a force platform with eyes open and closed. Anterior-posterior centre-of-pressure data were processed using wavelet analysis and sample entropy. Performance-based balance was assessed using the Timed Up-and-Go (TUG) and Dynamic Gait Index (DGI). The NP group demonstrated poorer functional performance (TUG and DGI, p<0.01) than the healthy controls. Wavelet analysis revealed that standing postural sway in the NP group was positively skewed towards the lower frequency movement (very-low [0.10-0.39Hz] frequency content, p<0.01) and negatively skewed towards moderate frequency movement (moderate [1.56-6.25Hz] frequency content, p=0.012). Sample entropy showed no significant differences between groups (p>0.05). Our results demonstrate that older adults with NP have poorer balance than controls. Furthermore, wavelet analysis may reveal unique insights into postural control mechanisms. Given that centre-of-pressure signal movements in the very-low and moderate frequencies are postulated to be associated with vestibular and muscular proprioceptive input respectively, we speculated that, because NP demonstrate a diminished ability to recruit the muscular proprioceptive system compared to controls, they rely more on the vestibular system for postural stability.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/24530119/", "type": "article", "institutions": [{"id": "https://openalex.org/I165143802", "name": "The University of Queensland", "country": "AU", "collaborators": ["June Quek", "Sandra Brauer", "Julia Treleaven"], "geo": {"city": "Brisbane", "geonames_city_id": "2174003", "region": "Queensland", "country_code": "AU", "country": "Australia", "latitude": -27.46794, "longitude": 153.02809}, "ror": "https://ror.org/00rqy9422"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["June Quek"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}], "provenance": ["https://openalex.org/W2021132921", "https://pubmed.ncbi.nlm.nih.gov/24530119/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84897114182&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": null, "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84897114182&origin=inward", "scopusDoi": "10.1016/j.gaitpost.2014.01.009"}, {"id": "W1991921688", "title": "Physical Activity Measured Using Global Positioning System Tracking in Non–Small Cell Lung Cancer", "year": 2014, "doi": "10.1177/1534735414542484", "url": "https://doi.org/10.1177/1534735414542484", "authors": ["Catherine L.

Fifty individuals with NSCLC from 3 Australian tertiary hospitals and 35 similar-aged healthy individuals without cancer were included. Individuals with NSCLC were assessed pretreatment. Primary measures were triaxial accelerometery (steps/day) and GPS tracking (outdoor PA behavior). Secondary measures were questionnaires assessing depression, motivation to exercise, and environmental barriers to PA. Between-group comparisons were analyzed using analysis of covariance.\n\nRESULTS: Individuals with NSCLC engaged in significantly less PA than similar-aged healthy individuals (mean difference 2363 steps/day, P = .007) and had higher levels of depression (P = .027) and lower motivation to exercise (P = .001). Daily outdoor walking time (P = .874) and distance travelled away from home (P = .883) were not different between groups.

Aims: To evaluate balance performance during an AECOPD compared to stable COPD and controls; to identify possible associations between balance measures, dyspnoea, and muscle strength. Methods: Twenty-six hospitalised patients with AECOPD (FEV 1 , 48±11 %pred) were evaluated prior to discharge using clinical balance tests and centre of pressure analyses, using the Nintendo Wii® balance board. Results were compared to 41 participants with stable COPD (FEV 1 , 45±16 %pred) and 25 matched healthy controls. Dyspnoea was assessed using the Medical Research Council scale and quadriceps strength measured by hand-held dynamometry. Mixed model analysis, paired t-test and regression were used. Results: Patients with AECOPD presented an impaired performance on anteroposterior displacement of centre of pressure (dAP) on both flat (3.9±1.2 vs 3.3±1.0 vs 2.8±0.6, p≤.01) and foam surfaces (7.0±2.2 vs 5.9±1.7 vs 4.6v1.2, p≤.02), compared with both stable and healthy elderly groups. Increased dyspnoea score and lower quadriceps strength were independently associated with a larger dAP amplitude (p<.03), and explained 40% of dAP variance during AECOPD. Conclusion: Patients with AECOPD have poorer balance, especially in the forward/backward direction compared with stable COPD and healthy controls; increased dyspnoea and lower muscle strength were associated with the poorer balance performance.", "abstractSource": "https://openalex.org/W1860877085", "type": "conference-abstract", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Cristino Carneiro Oliveira", "Annemarie L.

An Android phone was fixed on a helmet, which was then securely fastened on the participant's head. Cervical-spine ROM in flexion, extension, lateral flexion and rotation were performed in sitting with concurrent measurements obtained from both a 3DMA system and the phone.The phone demonstrated moderate to excellent (ICC = 0.53-0.98, Spearman ρ = 0.52-0.98) concurrent validity for ROM measurements in cervical flexion, extension, lateral-flexion and rotation. However, cervical rotation demonstrated both proportional and fixed bias. Excellent intra-rater reliability was demonstrated for cervical flexion, extension and lateral flexion (ICC = 0.82-0.90), but poor for right- and left-rotation (ICC = 0.05-0.33) using the phone. Possible reasons for the outcome are that flexion, extension and lateral-flexion measurements are detected by gravity-dependent accelerometers while rotation measurements are detected by the magnetometer which can be adversely affected by surrounding magnetic fields.\n\nCONCLUSION: The results of this study demonstrate that the tested Android phone application is valid and reliable to measure ROM of the cervical-spine in flexion, extension and lateral-flexion but not in rotation likely due to magnetic interference. The clinical implication of this study is that therapists should be mindful of the plane of measurement when using the Android phone to measure ROM of the cervical-spine.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/24742001/", "type": "article", "institutions": [{"id": "https://openalex.org/I165143802", "name": "The University of Queensland", "country": "AU", "collaborators": ["June Quek", "Sandra Brauer", "Julia Treleaven"], "geo": {"city": "Brisbane", "geonames_city_id": "2174003", "region": "Queensland", "country_code": "AU", "country": "Australia", "latitude": -27.46794, "longitude": 153.02809}, "ror": "https://ror.org/00rqy9422"}, {"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["June Quek", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Benjamin F.

Bilateral dissections were conducted on 10 embalmed cadavers. Strain transfer across the pubic symphysis was examined on seven of these cadavers. An AL contraction was simulated by applying a controlled load in the direction of its proximal tendinous fibers, and the resultant strain in the contralateral distal rectus sheath was measured using a foil-type surface mounted microstrain gage. Adductor longus attached to the antero-inferior aspect of the pubis. In 18 of the 20 limbs, the proximal attachment of AL was tendinous on its superficial surface and muscular on its deep surface. The proximal AL tendon was found in most instances to have secondary communications with structures such as the contralateral distal rectus sheath, pubic symphysis anterior capsule, ilio-inguinal ligament, and contralateral proximal AL tendon. Despite these consistent anatomical observations, strain measured in the contralateral distal rectus sheath upon unilateral loading of the proximal AL varied considerably between cadavers. Measured strain had an average ± 1SD of 0.23 ± 0.43%. The proximal attachment of AL contributes to an anatomical pathway across the anterior pubic symphysis that is likely required to withstand the transmission of large forces during multidirectional athletic activities.

Foot swing velocity possessed excellent relative (r=0.93) but only modest overall (rc=0.54) agreement. Step time (r=0.82 and rc=0.23) and stride time (r=0.69 and rc=0.14) possessed excellent and modest relative agreement respectively but poor overall agreement. Landmark location linearity was excellent (R(2)=0.991). This widely available, low-cost and portable system could provide clinicians with significant advantages for assessing some spatiotemporal gait parameters. However, caution must be taken when choosing outcome variables as some commonly reported variables cannot be accurately measured.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/24016679/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kelly J.

The purpose of this study was to explore the mediating effects of forward head posture (FHP) on the relationship between thoracic kyphosis and cervical mobility in older adults with cervical spine dysfunction. Fifty-one older adults (30 females, mean[SD]age = 66[4.9] years) with cervical spine dysfunction - that is, cervical pain with or without referred pain, numbness or paraesthesia - participated. Pain-related disability was measured using the neck disability index (NDI). Thoracic kyphosis was measured using a flexicurve. FHP was assessed via the craniovertebral angle (CVA) measured from a digitized, lateral-view photograph of each subject. Cervical ROM - namely, upper and general cervical rotation and cervical flexion - was measured by the Cervical Range-of-Motion (CROM) device. Greater thoracic kyphosis was significantly associated with lesser CVA (Spearman ρ = -0.48) whereas greater CVA was significantly associated with greater cervical flexion (Spearman ρ = 0.30) and general rotation ROM (ρ = 0.33), but not with upper cervical rotation ROM (ρ = 0.15). Bootstrap mediational analyses, adjusted for age, gender, weight and NDI, revealed significant indirect effects of thoracic kyphosis on cervical flexion and general rotation ROM through a FHP. Our results show that FHP mediated the relationship between thoracic kyphosis and cervical ROM, specifically general cervical rotation and flexion. These results not only support the justifiable attention given to addressing FHP to improve cervical impairments, but they also suggest that addressing thoracic kyphosis impairments may constitute an \"upstream\" approach.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/22959228/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["June Quek", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

Commercially available gaming systems, such as the Nintendo(®) (Kyoto, Japan) Wii™, have been widely adopted clinically; however, there is limited evidence supporting their feasibility and efficacy for improving balance performance following stroke. The aim of this trial is to investigate the clinical feasibility and efficacy of using the Nintendo Wii gaming system as an adjunct to standard care to improve balance performance following stroke in an inpatient rehabilitation setting.\n\nSUBJECTS AND METHODS: Thirty participants undergoing inpatient stroke rehabilitation will be recruited into this Phase II, single-blind, randomized controlled trial. Participants will be allocated into a Balance or Upper Limb Group, and both groups will perform activities using the Nintendo Wii in addition to their standard care. Participants will attend three 45-minute sessions per week, for a minimum of 2 and a maximum of 4 weeks.\n\nRESULTS: The main focus of the study is to investigate the feasibility of the intervention protocol. This will be evaluated through recruitment, retention, adherence, acceptability, and safety. The Step Test and Functional Reach Test will be the primary efficacy outcomes. Secondary outcomes will include force platform, mobility, and upper limb measures. Assessments will occur at baseline, 2 weeks, and 4 weeks after study entry.\n\nDISCUSSION: To the authors' knowledge, this will be the largest randomized clinical trial to investigate the feasibility and efficacy of the Nintendo Wii gaming system for improving balance performance in a stroke population.

The aim of this research is to determine whether commercially-available Wii Balance Boards with customized software providing real-time feedback could be used in a clinical setting to evaluate and improve weight-bearing asymmetry in people with various neurological conditions.\n\nMETHODS: Twenty participants (age = 43.25 ± 19.37 years) receiving physiotherapy as a result of a neurological condition performed three trials each of two tasks (static standing and sit-to-stand) with and without visual feedback. Vertical forces were measured using available Wii Balance Boards coupled with customized software that displayed visual feedback in real-time. Primary outcome measures included weight-bearing asymmetry as a percentage of body mass, peak force symmetry index, and a visual analogue scale score rating self-perceived level of asymmetry.\n\nRESULTS: Weight-bearing asymmetry during the static balance task was significantly reduced (Z = -2.912, p = 0.004, ES = 0.65) with visual feedback. There was no significant difference (Z = -0.336, p = 0.737) with visual feedback for the dynamic task, however subgroup analysis indicated that those with higher weight-bearing asymmetry responded the most to feedback. Correlation analysis revealed little or no relationship between participant perception of weight-bearing asymmetry and the results for the static or dynamic balance task (Spearman's rho: ρ = 0.138, p = 0.561 and ρ = 0.018, ρ =0.940 respectively).\n\nCONCLUSIONS: These findings suggest that weight-bearing asymmetry can be reduced during static tasks in patients with neurological conditions using inexpensive commercially-available Wii Balance Boards coupled with customized visual feedback software. Further research is needed to determine whether real-time visual feedback is appropriate for reducing dynamic weight-bearing asymmetry, whether improvements result in improved physical function, and how cognitive and physical impairments influence the patient's ability to respond to treatment.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/23849318/", "type": "article", "institutions": [{"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Joanna Foo", "Kade L.

The aim of this study was to assess the intra-rater reliability and validity of this system for assessing static foot posture.\n\nMETHODS: Three measures were used to assess static foot posture; traditional visual observation using the Foot Posture Index (FPI), a 3D motion analysis (3DMA) system and software designed to collect and analyse image and depth data from the Kinect. Spearman's rho was used to assess intra-rater reliability and concurrent validity of the Kinect to evaluate foot posture, and a linear regression was used to examine the ability of the Kinect to predict total visual FPI score.\n\nRESULTS: The Kinect demonstrated moderate to good intra-rater reliability for four FPI items of foot posture (ρ = 0.62 to 0.78) and moderate to good correlations with the 3DMA system for four items of foot posture (ρ = 0.51 to 0.85). In contrast, intra-rater reliability of visual FPI items was poor to moderate (ρ = 0.17 to 0.63), and correlations with the Kinect and 3DMA systems were poor (absolute ρ = 0.01 to 0.44). Kinect FPI items with moderate to good reliability predicted 61% of the variance in total visual FPI score.\n\nCONCLUSIONS: The majority of the foot posture items derived using the Kinect were more reliable than the traditional visual assessment of FPI, and were valid when compared to a 3DMA system. Individual foot posture items recorded using the Kinect were also shown to predict a moderate degree of variance in the total visual FPI score. Combined, these results support the future potential of the Kinect to accurately evaluate static foot posture in a clinical setting.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/23566934/", "type": "article", "institutions": [{"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Benjamin F.

However, it remains unclear whether the upper cervical spine rotation ROM asymmetry is associated with postural stability.\n\nMETHODS: Using the cervical range-of-motion device to assess upper cervical spine ROM via the cervical flexion-rotation test, we classified 54 older adults with neck pain (30 females; mean [standard deviation] age, 66 [5] yr) into the (1) symmetrical group (SYM; n = 20; ≤5° side-to-side difference) or (2) asymmetrical group (ASYM; n = 34; >5° difference). Standing postural control was characterized by the center-of-pressure (CoP) movements measured using a Balance Board. Other measures included habitual, fast-paced gait speed and neck pain. Both groups were compared on the various measures using Welch t tests.\n\nRESULTS: Although the ASYM group had 26% greater anteroposterior postural sway than the SYM (P < 0.01), both groups did not differ on postural sway velocity, gait speed, and neck pain intensity. Analyzing the frequency content of the postural sway using wavelet analysis (a modern, nonlinear signal processing method) shed further light: the standing postural sway in the ASYM group was skewed toward lower frequency movement (ultralow [< 0.10Hz] frequency content, anteroposterior: 6.7% in ASYM, 4.7% in SYM, P = 0.01; medial-lateral: 4.2% in ASYM, 3.4% in SYM, P = 0.045).\n\nCONCLUSION: The ASYM group seemed to have compensated for their altered somatosensory input to achieve similar functional levels as the SYM group. Given what is known about the association between ultralow frequency postural sway and visual input, we speculated that the postural strategy adopted by the ASYM group was adaptive and that this group may be relying on the visual system to achieve these compensations.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/23778365/", "type": "article", "institutions": [{"id": "https://openalex.org/I2251586001", "name": "Singapore General Hospital", "country": "SG", "collaborators": ["June Quek", "Yong‐Hao Pua"], "geo": {"city": "Singapore", "geonames_city_id": "1880252", "region": null, "country_code": "SG", "country": "Singapore", "latitude": 1.28967, "longitude": 103.85007}, "ror": "https://ror.org/036j6sg82"}, {"id": "https://openalex.org/I4210130383", "name": "Australian Physiotherapy Association", "country": "AU", "collaborators": ["June Quek"], "geo": {"city": "Camberwell", "geonames_city_id": "2172686", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.8481559753418, "longitude": 145.07882690429688}, "ror": "https://ror.org/02pehm937"}, {"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["June Quek"], "geo": {"city": "North Sydney", "geonames_city_id": "2154855", "region": "New South Wales", "country_code": "AU", "country": "Australia", "latitude": -33.839, "longitude": 151.2072}, "ror": "https://ror.org/04cxm4j25"}, {"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

The effect of a secondary task on postural control has, however, not been determined. The purpose of this case-control study was to compare postural control in patients following ACL reconstruction with healthy individuals with and without a secondary task.\n\nPARTICIPANTS: 45 patients (30 men and 15 women) participated at least 6 months following primary ACL reconstruction surgery. Participants were individually matched by age, gender and sports activity to healthy controls.\n\nMATERIALS: Postural control was measured using a Nintendo Wii Balance Board and customised software during static single-leg stance and with the addition of a secondary task. The secondary task required participants to match the movement of an oscillating marker by adducting and abducting their arm.\n\nMAIN OUTCOME MEASURES: Centre of pressure (CoP) path length in both medial-lateral and anterior-posterior directions, and CoP total path length.\n\nRESULTS: When compared with the control group, the anterior-posterior path length significantly increased in the ACL reconstruction patients' operated (12.3%, p=0.02) and non-operated limbs (12.8%, p=0.02) for the single-task condition, and the non-operated limb (11.5%, p=0.006) for the secondary task condition. The addition of a secondary task significantly increased CoP path lengths in all measures (p<0.001), although the magnitude of the increase was similar in both the ACL reconstruction and control groups.\n\nDISCUSSION: ACL reconstruction patients showed a reduced ability in both limbs to control the movement of the body in the anterior-posterior direction.

Twenty healthy adults were trained to modify their gait to obtain a lateral trunk lean angle of 10°. Real-time biofeedback of the lateral trunk lean angle was provided on a computer screen in front of the subject using data extracted from the Kinect skeletal tracking algorithm. Marker coordinate data were concurrently recorded using the 3DMA system, and the similarity and equivalency of the trunk lean angle data from each system were compared. The lateral trunk lean angle data obtained from the Kinect system without any form of calibration resulted in errors of a high (>2°) magnitude (mean error=3.2±2.2°). Performing global and individualized calibration significantly (P<0.001) improved this error to 1.7±1.5° and 0.8±0.8° respectively. With the addition of a simple calibration the anatomical position coordinates of the Kinect can be used to create a real-time biofeedback system for gait retraining.

These were therapist manual facilitation, the use of a gait assistive device, treadmill walking with handrail support, and 4 variations of body weight-support treadmill training with combinations of handrail and/or therapist support.\n\nMAIN OUTCOME MEASURES: Mediolateral COM movement was analyzed in terms of displacement amplitude (overall range of motion), timing (relative to stride time), and stability (steadiness of the movement). Normative values for these measures were acquired from 25 healthy participants walking at a self-selected comfortable pace.\n\nRESULTS: Body weight-support treadmill training without any additional support resulted in significantly (P<.05) greater amplitude, altered timing, and reduced movement stability compared with nonpathologic gait. Allowing handrail support or therapist facilitation reduced this effect and resulted in treadmill training (± body weight support) having lower movement amplitudes when compared with the other training methods. Therapist manual facilitation most closely matched nonpathologic gait for timing and stability.\n\nCONCLUSIONS: In the context of overall dynamic gait coordination, no single method of training provides the optimal stimulus. A training program that uses a variety of techniques may provide a beneficial rehabilitation response.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/22325681/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Gavin Williams", "Adam L.

Fifteen elite Australian Rules Footballers and 32 age-matched, untrained participants were tested for measures of WBA while squatting. The NWBB and customized software provided real-time visual feedback of WBA during half of the trials. Outcome measures included the mean mass difference (MMD) between limbs, interlimb symmetry index (SI), and percentage of time spent favoring a single limb (TFSL). Significant reductions in MMD (p = 0.028) and SI (p = 0.007) with visual feedback were observed for the entire group data. Subgroup analysis revealed significant reductions in MMD (p = 0.047) and SI (p = 0.026) with visual feedback in the untrained sample; however, the reductions in the trained sample were nonsignificant. The trained group showed significantly less WBA for TFSL under both visual conditions (no feedback: p = 0.015, feedback: p = 0.017). Correlation analysis revealed that participants with high levels of WBA had the greatest response to feedback (p < 0.001, ρ = 0.557). In conclusion, WBA exists in healthy untrained adults, and these asymmetries can be reduced using real-time visual feedback provided by an NWBB-based system.

This study assessed the concurrent validity of the Microsoft Kinect™ against a benchmark reference, a multiple-camera 3D motion analysis system, in 20 healthy subjects during three postural control tests: (i) forward reach, (ii) lateral reach, and (iii) single-leg eyes-closed standing balance. For the reach tests, the outcome measures consisted of distance reached and trunk flexion angle in the sagittal (forward reach) and coronal (lateral reach) planes. For the standing balance test the range and deviation of movement in the anatomical landmark positions for the sternum, pelvis, knee and ankle and the lateral and anterior trunk flexion angle were assessed. The Microsoft Kinect™ and 3D motion analysis systems had comparable inter-trial reliability (ICC difference=0.06±0.05; range, 0.00-0.16) and excellent concurrent validity, with Pearson's r-values >0.90 for the majority of measurements (r=0.96±0.04; range, 0.84-0.99). However, ordinary least products analyses demonstrated proportional biases for some outcome measures associated with the pelvis and sternum. These findings suggest that the Microsoft Kinect™ can validly assess kinematic strategies of postural control.

Electromyography of the peroneus longus, tibialis anterior and medial gastrocnemius was also recorded and analysed. A Friedman’s ANOVA was used to evaluate differences between shoe conditions, and a Wilcoxon signed ranks test was conducted to establish where the differences occurred. The results demonstrated that midfoot-tibia angles were significantly more supinated during the loading phase when wearing the experimental shoe (median = 47.70°) than when wearing a neutral shoe (median = 41.50°; p = 0.008) or a neutral shoe with a foot orthotic (median = 42.17°; p =0.008). In the midstance phase, supination angles in both the orthotic and experimental shoes were higher than that of the neutral shoe, with the former reaching significance (median = 19.56°; p = 0.006). During the propulsive phase findings were similar, with a significantly more supinated position in the experimental shoe (median = 48.30) than the neutral shoe (median = 37.47°; p = 0.006) or the neutral shoe with a foot orthotic (median = 40.87°; p =0.010). No significant differences were observed for any muscle group at any stage of the gait cycle.

The purpose of this study was to evaluate the cross-sectional associations of knee extensor strength, standing balance, and their interaction with physical function.\n\nMETHODS: One hundred four older adults with end-stage knee osteoarthritis awaiting a total knee replacement (mean ± SD age 67 ± 8 years) participated. Isometric knee extensor strength was measured using an isokinetic dynamometer. Standing balance performance was measured by the center of pressure displacement during quiet standing on a balance board. Physical function was measured by the self-report Short Form 36 (SF-36) questionnaire and by the 10-meter fast-pace gait speed test.\n\nRESULTS: After adjustment for demographic and knee pain variables, we detected significant knee strength by standing balance interaction terms for both SF-36 physical function and fast-pace gait speed. Interrogation of the interaction revealed that standing balance in the anteroposterior plane was positively related to physical function among patients with lower knee extensor strength. Conversely, among patients with higher knee extensor strength, the standing balance-physical function associations were, or tended to be, negative.\n\nCONCLUSION: These findings suggest that although standing balance was related to physical function in patients with knee osteoarthritis, this relationship was complex and dependent on knee extensor strength level.

A more complete understanding of the biomechanical inter-relations among the anatomical structures commonly implicated in AGP is therefore required. METHODS: Force transfer across the pubic symphysis in eight cadaveric specimens was examined by simulating an adductor longus (AL) contraction and assessing elongation in the contra-lateral abdominal rectus sheath (RS). This was performed by applying a variety of controlled loads to the AL and measuring tissue strain in the contra-lateral distal RS using calibrated strain gauges. RESULTS: A Wilcoxon Signed Rank test was performed on the data, and it was observed that the RS underwent statistically significant elongation when load was applied to the contra-lateral AL. In addition, observations made during the anatomical dissection revealed that fibres of the AL tendon extended above its insertion into the pubic tubercle in multiple directions, including direct connections with the RS. DISCUSSION: The results of this study indicate that AL has the capacity to transmit force across the pubic symphysis. These findings have implications for the pathogenesis of the AGP. The presence of strong connections between the AL and RS would suggest that these tissues are likely to be subjected to high loads during athletic activities. Targeted strengthening exercises for these particular muscles might therefore be of importance in the rehabilitation of AGP.", "abstractSource": "https://openalex.org/W2319029932", "type": "conference-abstract", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kimberley J.

In this study an inexpensive, wireless and portable timing light system was created using the infrared camera in Nintendo Wii hand controllers (NWHC).\n\nDESIGN: System creation with gold-standard validation.\n\nMETHOD: A Windows-based software program using NWHC to replicate a dual-beam timing gate was created. Firstly, data collected during 2m walking and running trials were validated against a 3D kinematic system. Secondly, data recorded during 5m running trials at various intensities from standing or flying starts were compared to a single beam CTLS and the independent and average scores of three handheld stopwatch (HS) operators. Intraclass correlation coefficient and Bland-Altman plots were used to assess validity. Absolute error quartiles and percentage of trials in absolute error threshold ranges were used to determine accuracy.\n\nRESULTS: The NWHC system was valid when compared against the 3D kinematic system (ICC=0.99, median absolute error (MAR)=2.95%). For the flying 5m trials the NWHC system possessed excellent validity and precision (ICC=0.97, MAR<3%) when compared with the CTLS. In contrast, the NWHC system and the HS values during standing start trials possessed only modest validity (ICC<0.75) and accuracy (MAR>8%).\n\nCONCLUSIONS: A NWHC timing light system is inexpensive, portable and valid for assessing running velocity. Errors in the 5m standing start trials may have been due to erroneous event detection by either the commercial or NWHC-based timing light systems.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/21247802/", "type": "article", "institutions": [{"id": "https://openalex.org/I86695891", "name": "Australian Catholic University", "country": "AU", "collaborators": ["Kade L.

This has important physiological implications for both eumenorrheic women with fluctuating estrogen levels and those with constant and attenuated estrogen levels, i.e., women using the monophasic oral contraceptive pill (MOCP). This study examined the effects of endogenous plasma estrogen levels on leg stiffness (K (LEG)) and foot center of pressure (COP) during hopping. Nineteen females (Age = 28.0 ± 4.2 years, Ht = 1.67 ± 0.07 m, Mass = 61.6 ± 6.8 kg) who had been using the MOCP for at least 12 months together with 19 matched, female, non-MOCP users (Age = 31.9 ± 7.3 years, Ht = 1.63 ± 0.05 m, Mass = 62.5 ± 5.9 kg) participated. Non-MOCP users were tested at the time of lowest (menstruation) and highest (≈ ovulation) estrogen whilst MOCP users were tested at Day 1 and Day 14 of their cycle. At each test session, K (LEG) (N m(-1) kg(-1)) and foot COP path length (mm) and path velocity (mm s(-1)) were determined from ground reaction force data as participants hopped at 2.2 Hz on a force plate. Statistical analysis revealed no significant (p < 0.05) differences for K (LEG). In contrast, significantly higher COP path length (30%) and COP path velocity (25%) were identified at ≈ ovulation compared to menstruation in the non-MOCP users. Whilst there was no evidence of an estrogen-induced effect on K (LEG); significantly elevated estrogen at ≈ ovulation presumably increased extensibility of connective tissue and/or diminished neuromuscular control.

Thirteen subjects with unilateral deficiency of the ACL (ACLD), 39 matched subjects with unilateral reconstructed ACL (ACLR; n = 25 with bone-patella tendon-bone (ACLR-PT) graft and n = 14 with combined semitendinosus and gracilis tendon (ACLR-STGT) graft) and 33 control subjects participated. Each subject performed maximal-effort isokinetic knee flexion repetitions at 180° s(-1) with electromyography (EMG) electrodes attached to their medial and lateral quadriceps muscles. Physical performance was assessed using the single-limb long hop for distance. Wavelet-derived mean instantaneous frequency (Mif) of flexor torque-time curves was significantly (p < 0.05) higher (i.e., less smooth) in ACLR-STGT subjects compared to the ACLD, ACLR-PT and control subjects. No significant differences existed for peak hamstrings strength (i.e., peak torque produced) or quadriceps antagonist EMG activity. Positive correlations were identified between hamstrings force steadiness and quadriceps antagonist activity for ACLD (r = 0.797), ACLR-PT (r = 0.467), and ACLR-STGT (r = 0.628) subjects. For ACLR-STGT subjects, reduced hamstrings force steadiness associated with poorer long-hop performance (r = -0.695). Reduced steadiness amongst ACLR-STGT subjects may reflect motor output variability of the antagonist (i.e., quadriceps dyskinesia) and/or agonist musculature-a maladaptive feature which potentially contributes to poorer single-limb hop performance.

We hypothesize that mediolateral (varus/valgus) knee acceleration during running gait will possess increased variability during menstruation when compared to ≈ovulation in women who do not take the monophasic oral contraceptive pill (MOCP). Thirty-six women (18 MOCP users: MOCP group and 18 non-pill users: NP group) performed six minute treadmill running trials at 10 km h−1 with an accelerometer fixed to the proximal tibia. Trials were performed at menstruation and ≈ovulation (for the MOCP group at a similar stage of the cycle) in a randomized order. The cyclicality of gross mediolateral tibial acceleration during 15 consecutive strides was assessed using combined wavelet and autocorrelation analysis. Longitudinal and anteroposterior accelerations were also examined. Repeated measures analysis of variance (ANOVA) tests were performed to assess differences at each stage of the menstrual cycle (α=0.05). Gross mediolateral acceleration in the NP group had significantly (P=0.022) increased variability at the time of menstruation compared to ≈ovulation, and was also significantly (P=0.011) more variable than the MOCP group at the corresponding time point. No significant difference was observed for any measure in the MOCP group. Increased variability in the NP users at menstruation may be a result of compromised motor control strategies. This provides further evidence of variability in performance and motor control during menstruation, and may have implications for a female athlete's risk of injury, particularly at the level of the knee.", "abstractSource": "https://openalex.org/W1995178618", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Simon Bartold", "Adam L.

The main objective of this study was to compare conditions for gait training for people with acquired brain injury (ABI). Seventeen people who had sustained an ABI and were unable to walk without assistance were recruited as a sample. Each participant was exposed to seven alternative gait training conditions in a randomized order. These were: (1) therapist manual facilitation; (2) the use of a gait-assistive device; (3) unsupported treadmill walking; and (4) four variations of body weight support treadmill training (BWSTT). Quantitative gait analysis was performed and Gait Profile Scores (GPS) were generated for each participant to determine which condition most closely resembled normal walking. BWSTT without additional therapist or self-support of the upper limbs was associated with more severe gait abnormality [Wilks' lambda = 0.20, F(6, 6) = 3.99, p = 0.047]. With the exception of therapist facilitation, the gait training conditions that achieved the closest approximation of normal walking required self-support of the upper limbs. When participants held on to a stable handrail, self-selected gait speeds were up to three times higher than the speeds obtained for over-ground walking [Wilks' lambda = 0.17, F(6, 7) = 5.85, p < 0.05]. The provision of stable upper-limb support was associated with high self-selected gait speeds that were not sustained when walking over ground. BWSTT protocols may need to prioritize reduction in self-support of the upper limbs, instead of increasing treadmill speed and reducing body weight support, in order to improve training outcomes.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/21174634/", "type": "article", "institutions": [{"id": "https://openalex.org/I2799990285", "name": "Epworth Hospital", "country": "AU", "collaborators": ["Gavin Williams", "Liz Moore"], "geo": {"city": "Melbourne", "geonames_city_id": "2158177", "region": "Victoria", "country_code": "AU", "country": "Australia", "latitude": -37.814, "longitude": 144.96332}, "ror": "https://ror.org/02ett6548"}, {"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Anthony G.

A pool of 26 male, semi-professional rugby league players (age: 23 ± 3 years, height: 180.8 ± 5.6 cm, mass: 95.7 ± 13.0 kg, estimated 1 repetition maximum bench press: 130 ± 20 kg) volunteered to participate in this study, which consisted of 2 components. First, the reliability of peak force (f) and displacement (d) measured during 4 different types of bench throws was assessed. These tests consisted of full range of motion (ROM) countermovement throws (FC), full ROM static start throws (FS), half ROM countermovement throws (HC), and half ROM static start throws (HS). For all measures, intraclass correlation coefficients were >0.80. The second component of this study examined the relationship between all measures, with a focus on the 2 simplest protocols to implement in an athlete assessment setting-FC and FS. A Pearson's correlation matrix revealed that a combination of FSd and FSf measures was moderately to highly correlated with all outcome measures, whereas neither FCd nor FCf was significantly correlated with HSf-a measure of the athlete's ability to produce force in the midrange of the movement with minimal elastic energy contribution. The results of this study suggest that, in situations where time efficiency is important, assessing full ROM bench throws from a static start may provide a representative measure of both upper-body full and partial ROM performance.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/20224448/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

Treatment often focuses on stretching the ITB and treating local inflammation at the lateral femoral condyle (LFC). We examine the area's anatomical and biomechanical properties. Anatomical studies of the ITB of 20 embalmed cadavers. The strain generated in the ITB by three typical stretching maneuvers (Ober test; Hip flexion, adduction and external rotation, with added knee flexion and straight leg raise to 30 degrees ) was measured in five unembalmed cadavers using strain gauges. Displacement of the Tensae Fasciae Latae (TFL)/ITB junction was measured on 20 subjects during isometric hip abduction. The ITB was uniformly a lateral thickening of the circumferential fascia lata, firmly attached along the linea aspera (femur) from greater trochanter up to and including the LFC. The microstrain values [median (IQR)] for the OBER [15.4(5.1-23.3)me], HIP [21.1(15.6-44.6)me] and SLR [9.4(5.1-10.7)me] showed marked disparity in the optimal inter-limb stretching protocol. HIP stretch invoked significantly (Z=2.10, P=0.036) greater strain than the SLR. TFL/ITB junction displacement was 2.0+/-1.6 mm and mean ITB lengthening was <0.5% (effect size=0.04).

The degenerative processes associated with tendinopathy may be associated with changes in the inherent mechanical properties of the musculotendinous unit.\n\nPURPOSE: The purpose of this study was to compare Achilles tendon-aponeurosis strain between male athletes with and without Achilles tendinopathy.\n\nSTUDY DESIGN: Cross-sectional study; Level of evidence, 3.\n\nMETHODS: Fifteen healthy men (age, 35 +/- 9 years; height, 1.78 +/- 0.05 m; mass, 79 +/- 11 kg) and 14 men with midportion Achilles tendinopathy (age, 40 +/- 8 years; height, 1.77 +/- 0.06 m; mass, 80 +/- 9 kg) who were all running over 20 km per week participated in the study. Each participant was tested in a single session that involved maximal isometric plantar flexion efforts being performed on a calf-raise apparatus while synchronous real-time ultrasonography of the triceps surae aponeurosis was recorded. Achilles tendon-aponeurosis strain (%) was calculated by dividing tendon displacement during plantar flexion by resting tendon length (intrarater reliability: intraclass correlation coefficient = .92).\n\nRESULTS: Participants in the Achilles tendinopathy group (5.2% +/- 2.6%) had significantly (P = .039) higher Achilles tendon-aponeurosis strain compared with the control group (3.4% +/- 1.8%). In contrast, there were no significant between-group differences for maximal isometric plantar flexion force.\n\nCONCLUSION: Achilles tendon-aponeurosis strain is higher in male athletes with tendinopathy than those without.

Neuromuscular function may be compromised during menstruation, which could result in reduced cyclicality of movement patterns. We hypothesize that mediolateral (varus/valgus) knee acceleration during running gait will possess increased variability during menstruation when compared to approximately ovulation in women who do not take the monophasic oral contraceptive pill (MOCP).\n\nMETHODS: Thirty-six women (18 MOCP users: MOCP group and 18 non-pill users: NP group) performed six-minute treadmill running trials at 10 km h(-1) with an accelerometer fixed to the proximal tibia. Trials were performed at menstruation and approximately equal ovulation (for the MOCP group at a similar stage of the cycle) in a randomized order. The cyclicality of gross mediolateral tibial acceleration during 15 consecutive strides was assessed using combined wavelet and autocorrelation analysis. Longitudinal and anteroposterior accelerations were also examined. Repeated measures analysis of variance (ANOVA) tests were performed to assess differences at each stage of the menstrual cycle (alpha=0.05).\n\nFINDINGS: Gross mediolateral acceleration in the NP group had significantly (P=0.022) increased variability at the time of menstruation compared to approximately equal ovulation, and was also significantly (P=0.011) more variable than the MOCP group at the corresponding time point. No significant difference was observed for any measure in the MOCP group.\n\nINTERPRETATION: Increased variability in the NP users at menstruation may be a result of compromised motor control strategies. This provides further evidence of variability in performance and motor control during menstruation, and may have implications for a female athlete's risk of injury.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/20400215/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Simon Bartold", "Adam L.

There is currently no validated system which can precisely quantify center of pressure (COP), an important component of standing balance, while being inexpensive, portable and widely available. The Wii Balance Board (WBB) fits these criteria, and we examined its validity in comparison with the 'gold standard'-a laboratory-grade force platform (FP). Thirty subjects without lower limb pathology performed a combination of single and double leg standing balance tests with eyes open or closed on two separate occasions. Data from the WBB were acquired using a laptop computer. The test-retest reliability for COP path length for each of the testing devices, including a comparison of the WBB and FP data, was examined using intraclass correlation coefficients (ICC), Bland-Altman plots (BAP) and minimum detectable change (MDC). Both devices exhibited good to excellent COP path length test-retest reliability within-device (ICC=0.66-0.94) and between-device (ICC=0.77-0.89) on all testing protocols. Examination of the BAP revealed no relationship between the difference and the mean in any test, however the MDC values for the WBB did exceed those of the FP in three of the four tests. These findings suggest that the WBB is a valid tool for assessing standing balance. Given that the WBB is portable, widely available and a fraction of the cost of a FP, it could provide the average clinician with a standing balance assessment tool suitable for the clinical setting.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/20005112/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

The purpose of this study was to examine the effects of an anterior cruciate ligament deficiency and reconstruction on knee extensor torque-time curve smoothness and to elucidate its association with hamstring (antagonist) activation and physical performance.\n\nMETHODS: Thirteen subjects who had a unilateral deficiency of the anterior cruciate ligament, twenty-five matched subjects with a unilateral reconstructed anterior cruciate ligament, and thirty-three control subjects performed knee extension and flexion repetitions bilaterally with maximal effort at 180 degrees/sec on a Cybex dynamometer. For the subjects with a deficient or a reconstructed anterior cruciate ligament, hamstring activation was measured electromyographically. Physical performance was measured by requiring subjects to perform single-limb timed hopping on the involved limb.\n\nRESULTS: In the subjects with a reconstructed or a deficient anterior cruciate ligament, wavelet-derived mean instantaneous frequency of the extensor torque-time curves was significantly (p < 0.001) higher in the involved limb than in the noninvolved limb and the limbs of the control subjects. Furthermore, for the subjects with a reconstructed or deficient anterior cruciate ligament, the mean instantaneous frequency of the extensor torque-time curves was positively associated with the level of hamstring antagonist activity (r = 0.580, p < 0.001) and with hopping performance (b = -0.943, p = 0.019), whereas isokinetic peak torque was not (b = -0.001, p = 0.797).\n\nCONCLUSIONS: For individuals who have a deficient or a reconstructed anterior cruciate ligament, an increased frequency content of the knee extensor torque is not, as previously and commonly assumed, a deleterious manifestation of the neuromuscular system. Rather, our results suggest that torque smoothness reduces as hamstring activation increases-a positive neuromuscular adaptation that enhances joint stability and, hence, optimizes physical performance. Wavelet-derived measures of extensor torque smoothness may provide valuable clinical information regarding joint function that conventional isokinetic torque measures cannot.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/19487521/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

Data analysis consisted of repeated measures MANOVA comparing groups, limbs and test. Repeated measures ANOVAs were also performed on the sprint times and the magnitude of inter-limb JS difference. For all data analysis the alpha level was set at p<0.05.

The force curves for each test were then divided into three intensity levels, set at low to moderate (0-75%), high (75-95%), and near-maximal force (95-100%). These values were obtained by determining the percentage of the range of motion (ROM) in which the force produced during each test was within these thresholds. The BT exercise produced significantly (p < 0.05) higher peak force than BP under both loading conditions. A significantly greater portion of the ROM during the 80% BT was at a high intensity in comparison with the BP. No significant differences were found between force intensity conditions at 55% loads. It can be concluded that performing the BT exercise results in a greater peak force output when compared with the traditional BP movement under both resistance training and maximal power loading conditions. Furthermore, performing the BT exercise with heavy loads results in a more efficient training method for maintaining high force levels throughout the ROM.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/18978630/", "type": "article", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

Support for this hypothesis would have important physiological implications for both eumenorrheic women and those with constant and attenuated estrogen levels; that is, women using the monophasic oral contraceptive pill (MOCP). PURPOSE: To elucidate the effect of circulating levels of estrogen on the strain properties of the human Achilles tendon (AT) in vivo. METHODS: Twenty females (Age=28.0±4.2yr; Ht=1.67±0.68m; Mass=61.6±6.8kg) who had been using the MOCP for at least 12 months together with 20 matched, non- MOCP users (Age=31.9±7.3yr; Ht=1.63±0.51m; Mass=62.5±5.9kg) participated in this study.

CONCLUSIONS: Lee et al., (2004) reported that increasing estrogen concentration reduced ligament fibroblast activity in response to mechanical loading and decreased Type I collagen mRNA production. Hence, a long-term reduction in blood estrogen levels due to MOCP administration is thought to have augmented exercise-induced collagen production in the AT thereby making the tendon less complaint. Decreased AT strain may alter the capacity of the muscle to harness elastic strain energy. If the effects of estrogen on tendon behaviour are consistent throughout the female body, these results provide a rationale for the lower rate of joint injuries in MOCP users as a reduction in tendon compliance would enhance joint support.", "abstractSource": "https://openalex.org/W2243677321", "type": "conference-abstract", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Adam L.

PURPOSE: To examine whether estrogen-induced changes in KAT are reflected in KLEG. METHODS: Twenty females (Age=28.0±4.2yr; Ht=1.67±0.68m; Mass=61.6±6.8kg) who had been using the MOCP for at least 12 months together with 20 matched, non-MOCP users (Age=31.9±7.3yr; Ht=1.63±0.51m; Mass=62.5±5.9kg) participated in this study. Non-MOCP users were tested at the time of lowest (menstruation) and highest (≈ovulation) estrogen whilst MOCP users, who exhibited constant and attenuated estrogen levels, were tested at Day 1 and Day 14 of their cycle. At each test session, maximal isometric plantarflexion efforts were performed on a calf-raise apparatus whilst synchronous real-time ultrasonography of the triceps surae aponeurosis was recorded. KAT (N·mm-1) was calculated from the load-displacement relationship at maximal plantarflexion force. KLEG (N·m-1) was determined from ground reaction force data as subjects hopped at 2.2Hz on a force plate. RESULTS: Repeated measures ANOVA revealed a significant (p < 0.05) main effect of subject group with significantly higher AT stiffness (18.4%) in the MOCP users compared to the non-MOCP users. In contrast, no significant differences were identified between test sessions or subject groups for KLEG. CONCLUSIONS: Increased KAT in MOCP users may be attributed to augmented exerciseinduced collagen production given that a long-term reduction in blood estrogen levels increases fibroblast activity and Type I collagen mRNA production (Lee et al., 2004). However, despite inherent differences in AT mechanical properties, KLEG of the MOCP users was similar to that of the non-MOCP users. Maintenance of KLEG in MOCP users may be a neuromechanical adaptation (referred to as \"muscle tuning\") whereby the activation patterns of the triceps surae muscles are modified to preserve the energy dissipating properties of the soft tissues. These results demonstrate that intrinsic differences in tendon behaviour can be modulated during a repetitive hopping task via neuromechanical adaptations.", "abstractSource": "https://openalex.org/W1987942253", "type": "conference-abstract", "institutions": [{"id": "https://openalex.org/I165779595", "name": "The University of Melbourne", "country": "AU", "collaborators": ["Kay M.

Nine strength-trained males participated in 2 randomly assigned, crossover design testing sessions consisting of 5 sets of 6 repetitions of 20-kg LCMJs with 3-minute rest intervals between sets. The preloading intervention was performed 3 minutes after the first set and 4 minutes before the second set of 20-kg LCMJs. The control (CON) group performed 1 set of 20-kg LCMJs, whereas the jump squat (JS) group performed 1 set of 40-kg LCMJs. The number of repetitions performed during each preloading condition was varied to match total concentric work between the 2 sessions. A significant (p < 0.05) preload x set interaction for PD was observed, with the JS group jumping significantly higher during the third set performed after the preload in comparison with the CON group. Analysis of peak power output and mean power output during the concentric movement for this set revealed that as the knee flexion angle increased, the effect of the preload was augmented. These results suggest that a single set of preloading exercises enhances performance during a lower-body explosive power training session; however, the effects of a single preloading set may not peak until midway through the training session.", "abstractSource": "https://pubmed.ncbi.nlm.nih.gov/16503676/", "type": "article", "institutions": [], "provenance": ["https://openalex.org/W2149945332", "https://pubmed.ncbi.nlm.nih.gov/16503676/", "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33645460120&origin=inward"], "identityEvidence": "Matched user-confirmed Scopus author ID 55279534900", "openAccessUrl": "https://figshare.com/articles/journal_contribution/The_acute_effects_of_a_single_set_of_contrast_preloading_on_a_loaded_countermovement_jump_training_session/13420181", "scopusAuthorId": "55279534900", "scopusRecord": "https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33645460120&origin=inward", "scopusDoi": "10.1519/16244.1"}, {"id": "W2112378494", "title": "The relationship between muscle architecture and performance", "year": 2006, "doi": "10.1016/j.jsams.2006.12.027", "url": "https://doi.org/10.1016/j.jsams.2006.12.027", "authors": ["Ross A.

The purpose of this pilot study was to determine whether an eccentric hamstring specific training programme results in favourable adaptations. Design Eccentric training consisting of the Nordic hamstring exercise performed twice a week for four weeks. Pre- and post-training concentric/concentric isokinetic testing of peak torque (PT) and position of peak torque (POS) was performed for both the quadriceps and hamstrings of both legs at 60°s −1 . Vertical jump height was also assessed. Participants Nine athletic, male subjects with no previous strength training experience. Results There was a significant increase in vertical jump height (pre=51.0±4.8cm, post=54.4±6.3cm, p =0.04), a significant reduction in quadriceps PT (pre=204.6±21.9 N.m., post=181.5±19.9 N.m., p =0.01), a significant decrease in hamstring POS from full knee extension (pre=32.5±7.4°, post=26.2±8.6°, p =0.01) and a significant hamstring POS difference between limbs (dominant=33.8±9.5°, non-dominant=24.9±6.5°, p =0.01). Conclusion Nordic hamstring exercise training may produce favourable neuromuscular adaptations for the possible prevention of hamstring injuries while enhancing performance in athletic, untrained males.", "abstractSource": "https://www.semanticscholar.org/paper/eda1edf3b5af732e8cd6c1cee32d96a6dd41662f", "type": "article", "institutions": [{"id": "https://openalex.org/I74899385", "name": "Central Queensland University", "country": "AU", "collaborators": ["Adam L.
