: Motor estimation error is an index of how accurately one's body movement is recognized. This study determines whether motor estimation error distance is a Parkinson's disease (PD)- or age-related disability using a two-step task. : The participants were 19 PD patients and 58 elderly people with disabilities. A two-step prediction test and an actual two-step test were performed. The motor estimation error distance (prediction of two-step distance minus actual two-step distance) and error rate between the two groups were compared. We conducted a correlation analysis between the motor estimation error and clinical factor (e.g., Hoehn and Yahr stage (H & Y), Unified Parkinson's Disease Rating Scale (UPDRS)) related to PD. : The motor estimation error distance was not significantly different between the PD patient group and the elderly group with disabilities. However, significant correlations between motor estimation error and H & Y, and between motor estimation error and UPDRS part II, were observed. The error rate was significantly correlated with the Fall Efficacy Scale. : The motor estimation error distance is influenced by both aging and PD.
运动估计误差是衡量一个人的身体运动被识别的准确程度的指标。本研究使用两步任务来确定运动估计误差距离是否是帕金森病（PD）相关或与年龄相关的残疾指标。
参与者为19名帕金森病患者和58名老年残疾人。进行了两步预测测试和实际两步测试。比较了两组之间的运动估计误差距离（两步距离预测值减去实际两步距离）和错误率。我们对运动估计误差与帕金森病相关临床因素（如Hoehn和Yahr分期（H&Y）、统一帕金森病评定量表（UPDRS））进行了相关性分析。
帕金森病患者组和老年残疾组之间的运动估计误差距离无显著差异。然而，观察到运动估计误差与H&Y以及运动估计误差与UPDRS第二部分之间存在显著相关性。错误率与跌倒效能量表显著相关。
运动估计误差距离受衰老和帕金森病的双重影响。
