Abstract

Aim: This study aimed to investigate the validity and reliability of the 2-Minute Step Test (2MST) in patients with lumbar spinal stenosis (LSS).

Method: This cross-sectional study involved 55 volunteers, aged 18-80, diagnosed with lumbar spinal stenosis. The participants were assessed using the 2MST, the 2-Minute Walk Test (2MWT), the 6-Minute Walk Test (6MWT), the Visual Analogue Scale (VAS), and the Oswestry Disability Index (ODI). To evaluate the reliability of the 2MST, test-retest reliability was determined by administering the 2MST again after a 7-day interval. The reliability analysis included the intraclass correlation coefficient (ICC) with a 95% confidence interval (CI), standard error of measurement (SEM), and minimum detectable change at the 95% confidence level (MDC₉₅). For concurrent validity, the correlations of the 2MST with the 2MWT, 6MWT, and ODI were assessed.

Results: The 2MST exhibited excellent test-retest reliability (ICC = 0.94, SEM = 5.56, MDC₉₅=15.41) in LSS patients. Additionally, the 2MST showed significant correlations with the 2MWT (r = 0.842, p < 0.001), 6MWT (r = 0.819, p < 0.001), and ODI score (r = -0.722, p < 0.001).

Conclusion: This study demonstrated that the 2MST is a valid and reliable tool for assessing exercise capacity in individuals with LSS.

腰椎管狭窄症患者 2 分钟台阶测试的结构有效性和可靠性。

目的：本研究旨在探讨腰椎管狭窄症（LSS）患者进行 2 分钟台阶测试（2MST）的有效性和可靠性：这项横断面研究涉及 55 名被诊断患有腰椎管狭窄症、年龄在 18-80 岁之间的志愿者。研究人员使用 2MST、2 分钟步行测试（2MWT）、6 分钟步行测试（6MWT）、视觉模拟量表（VAS）和 Oswestry 失能指数（ODI）对参与者进行了评估。为了评估 2MST 的可靠性，在间隔 7 天后再次进行 2MST 测试，以确定测试-再测可靠性。可靠性分析包括带有 95% 置信区间 (CI) 的类内相关系数 (ICC)、测量标准误差 (SEM) 和 95% 置信度下的最小可检测变化 (MDC95)。在并发有效性方面，评估了 2MST 与 2MWT、6MWT 和 ODI 的相关性：2MST 在 LSS 患者中表现出极佳的测试-再测可靠性（ICC=0.94，SEM=5.56，MDC95=15.41）。此外，2MST 与 2MWT 显示出显著的相关性（r = 0.842，p r = 0.819，p r = -0.722，p 结论：该研究表明，2MST 与 2MWT 之间存在显著的相关性：本研究表明，2MST 是评估 LSS 患者运动能力的有效而可靠的工具：NCT06060821。
