Evidence source and scope

Reliability of the Handgrip Strength Test in Elderly Subjects With Parkinson Disease.

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.

Bibliographic record from the original reports

Access labels embedded in these original reference strings are historical. Current access and exact checked components are stated separately below.

Scoped audit evidence

These are source- and component-level audit summaries as of 3 October 2026. Access and comparison scope can differ by report; none certifies every result or the underlying raw data.

Limitations: Only current scoped checks; archived captures not authenticated against live originals.

Parkinson’s disease strength

Parkinson’s disease strength component — Entire Jamar protocol bundle

Methods confirms every listed positioning, familiarization, effort, rest and scoring detail: seated Jamar handle 2, three pain-free three-second trials per hand, mean score, one-week retest, morning testing and usual medication without dyskinesia.

Limitations: AI-assisted source comparison; no raw-data verification.

Parkinson’s disease strength component — ICCs and SEM incompatibility

Table 2 gives ICCs .97 and .98, SDs 10.2 and 10.3 kg, and SEM .05 kg. The stated formula instead yields 1.7667 and 1.4566 kg. The report correctly flags a source inconsistency; raw data remain unavailable.

Limitations: AI-assisted source comparison; no raw-data verification.

Parkinson’s disease strength component — Source true-change rule and inconsistent signed differences

Discussion proposes ±.092 kg using two SEMs. Table 2 mixes opposite sign conventions for dominant and nondominant changes. These details match the report, and two SEMs is not conventional two-score MDC 95.

Source locator: Table 2 and Discussion

Limitations: Figure inspected in STR-03-04; historical erratum search cannot be reproduced, new bounded search in STR-03-05. AI-assisted source comparison; no raw-data verification.

Parkinson’s disease strength component — Grip agreement figure inspection

Figure 1 uses right/left rather than dominance labels and shows many points beyond the plotted purported 95% limits, including differences around−5.5 and−6.8 kg. The report's visual caution is supported.

Source locator: PMC Figure 1; audit evidence record

Limitations: A new erratum search has not established the historical 2 October claim. AI-assisted source comparison; no raw-data verification.

A new exact-DOI erratum/correction search identified no correction. This bounded negative search cannot prove absence or recreate the report's historical 2 October search.

Limitations: AI-assisted source comparison; no raw-data verification.
