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.
Parkinson’s disease — balance
- access status: original_methods_and_table_excerpts
Latest listed audit check, current for its stated components. Later recovery/refinement here supersedes earlier access limitations only where explicitly stated; it does not resolve unrelated source contradictions.
Fresh primary publisher Data Analysis excerpt independently states MDC = 1.96 × SEM × sqrt(2), with SEM = SD × sqrt(1 − ICC). Table 3 prints reaction-time SEM .17 and MDC95 .32. Recalculation gives .471, so the report’s warning about the source’s stated formula is confirmed. The other three quoted MDC values and protocol statements are also supported. This closes the last formula-attribution access gap; the full PDF remains unavailable. Source locator: audit evidence record, original Data Analysis/Table 3 Limit: Publisher cached section excerpt; not a complete PDF retrieval. No raw-data verification.
Earlier audit check 1 (historical evidence record). Its access limitations are superseded wherever the latest check above explicitly closes them. Retained for the distinct components and provenance, not as a current access statement.

Earlier audit check 2 (historical evidence record). Its access limitations are superseded wherever the latest check above explicitly closes them. Retained for the distinct components and provenance, not as a current access statement.
Original publisher Methods now independently confirms small, medium and large anterior/posterior MCT perturbations, ON testing, within ten days and harness. Table 3 confirms latency ICC .92 (.84–.96), SEM 2.7 ms and MDC95 7.4 ms. The source does not establish MIC or prospective fall prediction. These protocol and table claims are now verified from the original article excerpt. The original publisher Methods and Table 3 verify protocol and the three cited MDC values. Table 3 prints LOS reaction-time SEM .17 and MDC95 .32; 1.96 × sqrt(2) × .17 = .471, which does not reconcile with .32. The original article’s exact printed formula has not been independently inspected, so the phrase “its stated formula” remains only partially verified. This does not justify implementing the anomalous .32-second threshold. Source locator: audit evidence record, Study Design/Testing Procedures/Force platform measures/Table 3 Limit: Formula attribution remains unverified; complete PDF not retrieved.
Limitations: Only scoped comparisons, not whole-paper certification.
