The objectives of this study were to examine (1) the intrarater, interrater, and test-retest reliability of the timed 360° turn test in people with Parkinson's Disease (PwPD); (2) the minimum detectable change in the timed 360° turn test times; (3) the concurrent and discriminant validity of the timed 360° turn test; (4) the cut-off times which best discriminate PwPD from healthy people and fallers from non-fallers with Parkinson's Disease (PD).
Fifty-four PwPD and 32 healthy people were included. The timed 360° turn test was administered along with Timed Up and Go Test, Berg Balance Scale, Four Square Step Test, Unified Parkinson's Disease Rating Scale, and Hoehn and Yahr Scale. In addition, PwPD were categorized into fallers and non-fallers based on fall history. Reliability analyses were assessed using intraclass correlation coefficients in a subgroup of 38 PwPD.
The timed 360° turn test had excellent intrarater, interrater, and test-retest reliability. It was strongly correlated with other outcome measures (p < 0.001). In both sides, significant differences in the timed 360° turn test times were found between PwPD and healthy people and between fallers and non-fallers with PD (p < 0.001 and p < 0.001, respectively). The timed 360° turn test times of 3.76-3.89 s were found to best discriminate PwPD from healthy people, while 5.46-5.74 s were found to best discriminate fallers from non-fallers with PD. The minimum detectable change in the timed 360° turn test times were 1.98 s for dominant side and 1.48 s for non-dominant side in PwPD.
The timed 360° turn test is a reliable, valid, and clinically available tool for assessing turning ability in PwPD.
本研究的目的是：（1）检验帕金森病患者（PwPD）360°转身计时测试的组内、组间和重测信度；（2）360°转身计时测试时间的最小可检测变化；（3）360°转身计时测试的同时效度和判别效度；（4）最佳区分 PwPD 与健康人、帕金森病跌倒者与非跌倒者的截断时间。
纳入 54 例 PwPD 和 32 例健康人。同时进行 360°转身计时测试、计时起立行走测试、伯格平衡量表、四方步测试、统一帕金森病评定量表和 Hoehn 和 Yahr 量表评估。此外，根据跌倒史将 PwPD 分为跌倒者和非跌倒者。对 38 例 PwPD 的亚组进行组内相关系数评估可靠性分析。
360°转身计时测试具有极好的组内、组间和重测信度。它与其他结果测量指标高度相关（p<0.001）。在两侧，PwPD 与健康人之间以及 PD 跌倒者与非跌倒者之间的 360°转身计时测试时间存在显著差异（p<0.001 和 p<0.001）。发现 360°转身计时测试时间为 3.76-3.89 s 时，可最佳地区分 PwPD 与健康人，而 5.46-5.74 s 时，可最佳地区分 PD 跌倒者与非跌倒者。在 PwPD 中，优势侧 360°转身计时测试时间的最小可检测变化为 1.98 s，非优势侧为 1.48 s。
360°转身计时测试是一种可靠、有效且可临床应用的工具，可用于评估 PwPD 的转身能力。
