: To investigate (1) the intrarater, interrater, and test-retest reliability of the timed 360° turn test in people with Multiple Sclerosis (MS); (2) the minimum detectable change in the timed 360° turn test times; (3) the concurrent and discriminant validity of the timed 360° turn test times; and (4) the cut-off times that best discriminate people with MS from healthy people and fallers from non-fallers with MS.: Sixty-one people with MS (Expanded Disability Status Scale, EDSS, 0-6.5) and 34 healthy people were recruited in this cross-sectional study. The timed 360° turn test was administered along with the Timed Up and Go Test, Berg Balance Scale, Four Square Step Test, and EDSS by two independent raters.: The timed 360° turn test showed good intrarater, interrater, and test-retest reliability. Minimal detectable changes were 1.49 s and 1.53 s for the dominant and non-dominant sides, respectively. The timed 360° turn test was strongly correlated with other outcome measures. Significant differences in 360° turn times were found between people with MS and healthy people and between fallers and non-fallers with MS ( < .001 and < .001, respectively). The cut-off times of 2.65 s on the dominant side and 2.42 s on the non-dominant best discriminated people with MS from healthy people, while 3.65 s on the dominant side and 3.75 s on the non-dominant best discriminated fallers from non-fallers with MS.: The timed 360° turn test is a simple and reliable tool for assessing turning ability in MS.
（1）研究多发性硬化症（MS）患者 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°转身计时测试时间的同时和判别效度；（4）最佳区分 MS 患者与健康人、MS 跌倒者与非跌倒者的截断时间。
本横断面研究共纳入 61 名 MS 患者（扩展残疾状况量表，EDSS，0-6.5）和 34 名健康人。由两名独立评估者进行 360°转身计时测试，同时进行计时起立行走测试、伯格平衡量表、四方步测试和 EDSS 评估。
360°转身计时测试显示出良好的组内、组间和重测信度。优势侧和非优势侧的最小可检测变化分别为 1.49 秒和 1.53 秒。360°转身计时测试与其他结果测量指标高度相关。MS 患者与健康人、MS 跌倒者与非跌倒者之间的 360°转身时间存在显著差异（均<0.001）。优势侧 2.65 秒和非优势侧 2.42 秒的截断时间可最佳区分 MS 患者与健康人，而优势侧 3.65 秒和非优势侧 3.75 秒的截断时间可最佳区分 MS 跌倒者与非跌倒者。
360°转身计时测试是一种简单可靠的评估 MS 患者转身能力的工具。
