To investigate: (1) the interrater, and test-retest reliability of the coin rotation test (CRT) in people with Parkinson's Disease (PwPD); (2) the minimum detectable change in the CRT; (3) the concurrent and known-groups validity of the CRT; and (4) the cut-off times that best discriminate PwPD from healthy people and functionally dependent PwPD from functionally independent PwPD.
Forty-eight PwPD and 33 healthy people were included. The CRT was administered with the nine-hole peg test, Movement Disorders Society Sponsored Unified Parkinson's Disease Rating Scale, Hoehn and Yahr Scale, Parkinson's Disease Questionnaire-8, and Schwab and England Scale.
The CRT had excellent interrater and test-retest reliability. Minimal detectable changes were 5.96 and 8.23 s for the dominant and non-dominant hand, respectively. The CRT correlated with other outcome measures. Significant differences in the CRT times were found between PwPD and healthy people, and between functionally dependent PwPD and functionally independent PwPD. The cut-off times of 12.66 s on the dominant hand and 15.76 s on the non-dominant best discriminated PwPD from healthy people, while 22.99 s on the dominant hand and 23.48 s on the non-dominant best discriminated functionally dependent PwPD from functionally independent PwPD.
The CRT is a reliable, and clinically available tool for assessing manual dexterity in PwPD.Implications for rehabilitationThe coin rotation test is a reliable, valid, and clinically available tool for assessing manual dexterity in Parkinson's Disease.The minimal detectable changes of the coin rotation test are 5.96 s for dominant hand and 8.23 s for the non-dominant hand, which may useful for clinicians and researchers to detect in any true change in manual dexterity after any intervention.The coin rotation test correlated with Parkinson's Disease-specific measurement tools.The coin rotation test times may detect impaired manual dexterity between people with Parkinson's Disease and healthy people, and between functionally dependent and functionally independent in Parkinson's Disease population.
研究：（1）硬币旋转测试（CRT）在帕金森病患者（PwPD）中的评分者间信度和重测信度；（2）CRT 的最小可检测变化；（3）CRT 的同时效度和已知组效度；（4）最佳区分 PwPD 与健康人以及功能依赖型 PwPD 与功能独立型 PwPD 的截断时间。
纳入 48 名 PwPD 和 33 名健康人。使用九孔钉测试、运动障碍协会赞助的统一帕金森病评定量表、Hoehn 和 Yahr 量表、帕金森病问卷-8 和 Schwab 和 England 量表进行 CRT 测试。
CRT 具有极好的评分者间信度和重测信度。优势手和非优势手的最小可检测变化分别为 5.96 秒和 8.23 秒。CRT 与其他结果测量指标相关。在 PwPD 与健康人之间以及功能依赖型 PwPD 与功能独立型 PwPD 之间，CRT 时间存在显著差异。优势手的 12.66 秒和非优势手的 15.76 秒的截断时间可最佳区分 PwPD 与健康人，而优势手的 22.99 秒和非优势手的 23.48 秒的截断时间可最佳区分功能依赖型 PwPD 与功能独立型 PwPD。
CRT 是一种可靠且可临床应用的工具，可用于评估 PwPD 的手灵活性。
硬币旋转测试是一种可靠、有效且可临床应用的工具，可用于评估帕金森病患者的手灵活性。硬币旋转测试的最小可检测变化为优势手 5.96 秒，非优势手 8.23 秒，这对于临床医生和研究人员在任何干预后检测手灵活性的任何真实变化可能有用。硬币旋转测试与帕金森病特异性测量工具相关。硬币旋转测试时间可能会在帕金森病患者和健康人之间以及帕金森病人群中功能依赖型和功能独立型之间检测到手灵活性受损。
