Muscle Strength and Power in People With Parkinson Disease: A Systematic Review and Meta-analysis.
This note indexes a cited or audit-added source. It may be an original study, review, guideline, form or methods reference. Treat the specific design and the evidence below as authoritative; a source note is not automatically a primary study.

Parkinson’s disease strength component — Review search, eligibility, dual review, counts and evidence boundary
Methods specifies six databases searched on 14 October 2020, independent screening and extraction by two authors, 188 full-text assessments and 40 included studies. Aim 2 excluded manual testing, handheld dynamometry and 1 RM. Later papers are discussed without an updated systematic-search date. The PDF directs detailed searches, characteristics, psychometrics and quality assessments to separate supplements, which remain unavailable.

Parkinson’s disease strength component — Review aggregation, normalization, quality and absent meta-analytic diagnostics
Methods averages multiple actions into regional study values and divides by body mass when available, otherwise retaining absolute values. Sample-size weights apply to comparisons, associations and Hedges g. The main article supplies no I², tau², prediction intervals or aggregate sensitivity analyses. Discussion rates quality fair (5–9 of 14), with almost no blinding or confounder correction and absent or short follow-up. The report’s methodological description matches.

Parkinson’s disease strength component — Review strength/power ratios and figure-specific uncertainty
The text gives lower-limb strength 75% ON and 59% OFF, and upper-limb 85% and 87%. Visually inspected Figure 2 has upper-limb intervals crossing 100% in both states; lower-limb totals combine 17 ON and three OFF studies, with sparse contraction-specific cells. Figure 3 places the single power study under ON, around 60% for lower limbs and 20% for trunk. Table 1 identifies Lima’s ten PD participants and ten controls; the review includes 12 RFD studies and one power study. These summaries do not isolate a medication effect.

Parkinson’s disease strength component — Psychometric scope and exact Pang/Mak reference mismatch
Page 6 reports Purser’s 15 PD participants and Pang/Mak’s 43, with ICCs.92–.93 and.97–.98 for trunk/.97 for grip. It reports no validity, responsiveness, RFD or power measurement studies. Reference 23 instead identifies the hip-bone-density paper, DOI 10.2340/16501977-0311, independently checked as 34 women with hip/knee handheld ICCs.87–.90. The citation mismatch is confirmed. The likely intended trunk paper matches 43 PD/29 control participants in its abstract; its original ICCs remain unverified.

Limitations: Likely intended trunk-paper primary Methods/ICCs and review supplements remain unavailable; the report already treats those ICCs as unverified. AI-assisted source comparison; no raw-data verification.
Parkinson’s disease strength component — All reported association summaries and negative-squared labels
Page 8 gives function R²=.24 [.17, .31] ON and.18 [−.020, .37] OFF; ON UPDRS total=.39 [.11, .68] and motor=.40 [.22, .58]. Table 2 retains negative signs on squared correlations. Methods uses mainly simple associations for summary estimates. Page 12 describes weak RFD-function evidence from two papers by the same Pääsuke group. The report correctly distinguishes the printed negative confidence bound and mislabeled negative squared values from negative explained variance.

Parkinson’s disease strength component — Pereira review ratios and Pääsuke bibliography discrepancy
Table 1 gives Pereira ratios 8%, 4% and 3% at 50, 100 and 200 ms, from means 1.28/15.97, .68/15.95 and.41/13.23. Those ratios reproduce from the review table but do not resolve the primary Pereira figure/narrative conflict. Review reference 31 is “Motor performance testing in elderly women, ” Acta Kinesiol 2002;7(suppl):159–163, which differs from the report’s PD original reference 22. The report correctly refuses to merge these records silently.
