摘要
L 测试是为评估平衡和步态障碍而开发的。本研究的目的是评估 L 测试在 82 名多发性硬化症患者(PwMS)中使用时的重复测试可靠性和有效性。对于这些参与者,我们使用布兰-阿尔特曼分析法和类内相关系数(ICCs)来检验 L 测试第一次和第二次施测结果(间隔一天)之间的一致程度。我们计算了 L 测试的最小可检测变化(MDC)和测量标准误差(SEM)值,并通过将 L 测试结果与定时起立行走测试(TUG)和 10 分钟步行测试(10MWT)相关联来评估并发有效性。在进行这些测量之前,我们随机安排了参与者的测试顺序。布兰德-阿尔特曼分析表明,L 测试具有良好的再现性,一致性的上限和下限分别为 0.99 秒和-1.45 秒。L 测试的重测可靠性极佳,ICC 值为 0.996(95% CI:0.994-0.998)。克朗巴赫α系数为 0.996。我们发现 L 测试的 SEM 值为 0.35 秒,MDC 值为 0.97 秒。L 测试与 TUG 测试(rho = 0.936;p < .001)和 10MWT 测试(rho = 0.925;p < .001)均显示出很强的相关性。我们的结论是,L 测试是一种可靠有效的工具,可用于评估 PwMS 的功能活动能力和平衡能力。
Reliability and Validity of the L Test in Persons With Multiple Sclerosis.
The L Test has been developed to assess balance and gait disorders. Our aim in this study was to estimate the test-retest reliability and validity of the L Test when used with 82 persons with multiple sclerosis (PwMS). For these participants, we examined the degree of agreement between the results of a first and second administration of the L Test (separated by one day), using Bland-Altman analysis and intra-class correlation coefficients (ICCs). We computed minimal detectable change (MDC) and standard error of measurement (SEM) values for the L Test and evaluated concurrent validity by correlating L Test results with the Timed Up and Go test (TUG) and the 10-minute Walk Test (10MWT). Prior to administering these measurements, we randomized the sequence of the test administrations to our participants. The Bland-Altman analysis showed that L Test was reproducible, with upper and lower limits of agreement of 0.99 and -1.45 seconds, respectively. The L Test demonstrated excellent test-retest reliability, with an ICC value of 0.996 (95% CI: 0.994-0.998). Cronbach's alpha coefficient was 0.996. The performance of the L Test is measured by seconds required to complete the task, and we found the L Test SEM value to be 0.35 seconds, and its MDC value to be 0.97 seconds. The L Test showed a strong correlation with both the TUG test (rho = 0.936; p < .001) and the 10MWT (rho = 0.925; p < .001). We concluded that the L Test is a reliable and valid \ tool for assessing functional mobility and balance in PwMS.
