6分钟步行试验(6MWT)通常用来测量步行能力。本研究的目的是确定6MWT在积极接受住院康复治疗的中风患者中的重测信度和同时效度和结构效度。37名中风后接受住院康复治疗的患者参与研究；平均年龄为66.3岁，平均卒中开始时间为33.7天。患者接受了两次6MWT试验：试验间隔1-3天。采取的其他结果测量包括步态速度和功能独立性测量(TM)(FIM(TM))。6 MWT具有较高的重测信度，ICC2.1为0.973(95%CI=0.925~0.988)，最小可检测变化(MDC90)为54.1m，与步态速度(r=0.89)、运动(行走)FIM(TM)(r=0.69)、运动FIM(TM)(r=0.52)呈强至中度相关。6MWT是评价中风后步行能力的一项临床有用的指标。它是可靠的，并与中风后康复过程中常用的其他步行能力和功能测量有关。
The 6-minute walk test (6MWT) is commonly used to measure walking ability. The purpose of this study was to determine the test-retest reliability and concurrent and construct validity of the 6MWT in patients who were actively undergoing inpatient rehabilitation poststroke. Thirty-seven patients undergoing inpatient rehabilitation after a stroke participated; mean age was 66.3 years and mean time since stroke was 33.7 days. Patients underwent two 6MWT trials: with 1-3 days between trials. Additional outcome measures taken were gait speed and the Functional Independence Measure (TM) (FIM (TM)). The 6MWT exhibited high test-retest reliability; ICC2.1 0.973 (95% CI = 0.925-0.988) and a minimal detectable change (MDC90) of 54.1 m. The 6MWT was strongly to moderately correlated with gait speed (r=0.89), locomotion (walk) FIM (TM) (r=0.69), and motor FIM (TM) (r = 0.52). The 6MWT is a clinically useful measure of walking ability poststroke. It is reliable and is related to other measures of walking ability and function that are commonly used during rehabilitation after stroke.
