Abstract

Abstract Purpose: This study aimed to determine the inter- and intra-rater reliability of and minimal detectable changes (MDCs) at the 95% confidence interval in gait performance tests in patients with chronic hemiplegic stroke who can walk independently. Materials and Methods: Thirty patients with chronic hemiplegic stroke (24 men, 6 women, mean age 62.5 ± 11.6 years) were enrolled. Physical therapists (mean clinical experience: 9.1 ± 9.3 years) performed the timed up and go test (TUG), 10-m walk test (10MWT), and 6-min walk test (6MWT) 1 day apart. Reliability was evaluated using the intraclass correlation coefficient (ICC) and Bland–Altman analysis. Results: The ICC was ≥0.9 for all tests, and no systematic bias was found. MDC at the 95% confidence interval was 1.9 s for the TUG, 0.16 m/s for the 10MWT, and 28.4 m for the 6MWT. Discussion: We demonstrated excellent intra- and inter-rater reliability of all tests. These results suggest that gait performance tests are reliable. Conclusion: These commonly used gait performance tests demonstrated high reliability and can be recommended to evaluate clinically meaningful improvements in patients with chronic hemiplegic stroke who can walk independently.
慢性偏瘫卒中患者步态性能试验的可靠性和最小可检测变化
目的:本研究旨在确定能够独立行走的慢性偏瘫卒中患者步态性能测试中最小可检测变化(MDCs)在95%置信区间内的组间和组内可靠性。材料与方法:30例慢性偏瘫性脑卒中患者,男性24例,女性6例,平均年龄62.5±11.6岁。物理治疗师(平均临床经验:9.1±9.3年)间隔1天进行定时行走测试(TUG)、10米步行测试(10MWT)和6分钟步行测试(6MWT)。信度评估采用类内相关系数(ICC)和Bland-Altman分析。结果:所有试验的ICC均≥0.9,未发现系统性偏倚。95%置信区间上,TUG的MDC为1.9 s, 10MWT为0.16 m/s, 6MWT为28.4 m。讨论:我们证明了所有测试的出色的内部和内部信度。这些结果表明步态性能测试是可靠的。结论:这些常用的步态性能测试具有高可靠性,可推荐用于评估能够独立行走的慢性偏瘫卒中患者的临床有意义的改善。
