In the context of evaluating physical function in individuals with stroke, the 3-Meter Backward Walk Test (3MBWT) emerges as a potential tool of interest. The purpose of this study was to assess the test-retest reliability and concurrent validity of the 3MBWT and its correlation with falling incidents. Conducted in a neurological rehabilitation center, 35 ambulatory individuals with stroke were enrolled within a month post-stroke onset. These participants, with a Functional Ambulation Category score of ≥4, underwent the 3MBWT, Functional Gait Assessment (FGA), 10-Meter Walk Test (10MWT), and 6-Minute Walk Test (6MWT) under the supervision of different physiotherapists. The results indicate that the 3MBWT demonstrated high reliability, with an Intraclass Correlation Coefficient of 0.97 (95% CI: 0.95, 0.98). It also showed significant concurrent validity with other established walking tests like the 6MWT (r = -0.78) and 10MWT (r = 0.71), with a moderate correlation with the FGA (r = -0.54). No marked differences in test outcomes were observed between participants based on their fall history. Conclusively, the 3MBWT proves to be highly reliable and agrees well with existing walking function assessments for stroke patients, suggesting its potential as a time-efficient alternative.
在评估中风患者身体功能的背景下，3米向后行走测试（3MBWT）成为一种潜在的受关注工具。本研究的目的是评估3MBWT的重测信度和同时效度及其与跌倒事件的相关性。在一家神经康复中心进行，35名能够行走的中风患者在中风发作后一个月内入组。这些功能步行分类得分≥4的参与者，在不同物理治疗师的监督下，接受了3MBWT、功能性步态评估（FGA）、10米行走测试（10MWT）和6分钟步行测试（6MWT）。结果表明，3MBWT显示出高信度，组内相关系数为0.97（95%CI：0.95，0.98）。它与其他既定的行走测试如6MWT（r = -0.78）和10MWT（r = 0.71）也显示出显著的同时效度，与FGA有中度相关性（r = -0.54）。根据跌倒史，参与者之间在测试结果上未观察到明显差异。总之，3MBWT被证明具有高信度，并且与中风患者现有的行走功能评估结果吻合良好，表明其作为一种省时替代方法的潜力。
