Abstract

Background: Falls are a common challenge for people with Parkinson's disease (PwPD), driven by balance impairments and misaligned perceptions of balance abilities.

Objective: This study investigated the replicability and generalizability of the relationship between balance ability and perception discordance and fall risk.

Methods: Using baseline data from 2 clinical trials involving 171 PwPD, discordance was calculated using the Activities Specific Balance Confidence Scale and Timed Up and Go (TUG) or the Mini Balance Evaluation System's Test (MiniBEST).

Results: Findings supported the replicability of discordance as a predictor of fall risk, with results consistent across measures. While TUG-derived discordance was statistically significant, MiniBEST-derived discordance showed generalizability without statistical inferiority.

Conclusion: These results emphasize the relevance of balance perception and its misalignment with ability as fall risk predictors.

帕金森病患者平衡能力与知觉的不一致性及其与跌倒的关系：一项重复分析

背景：跌倒是帕金森病（PwPD）患者的常见挑战，由平衡障碍和对平衡能力的错误认知驱动。目的：探讨平衡能力、知觉不协调与跌倒风险之间关系的可重复性和普遍性。方法：使用2项涉及171名PwPD患者的临床试验的基线数据，使用活动特定平衡置信度量表和计时起走（TUG）或迷你平衡评估系统测试（MiniBEST）计算不一致性。结果：研究结果支持不一致性作为跌倒风险预测因子的可重复性，结果在不同测量中一致。虽然tug衍生的不一致性在统计上是显著的，但minibest衍生的不一致性显示出无统计学劣效性的普遍性。结论：这些结果强调了平衡知觉及其与能力偏差作为跌倒风险预测因素的相关性。
