To investigate the test-retest reliability and concurrent validity of 2MST for assessing the physical performance of patients with total knee arthroplasty (TKA).
Fifty-one patients with TKA, aged more than 18 years, of both sexes, and underwent a primary TKA at least six months ago, were included in this study. The intraclass correlation coefficient (ICC) and 95% confidence interval (CI), standard error of measurement (SEM), and minimum detectable change at the 95% confidence level (MDC) were used to determine the reliability of 2MST. In the validity, the correlations of the 2MST between the six-minute walk test (6MWT) and the two-minute walk test (2MWT) were assessed.
The reliability of 2MST was excellent (ICC = 0.97, SEM = 2.76, MDC = 7.6). There was a moderate correlation between 2MST and 6MWT ( = 0.586; = 0.000), as well as between 2MST and 2MWT ( = 0.633; = 0.000).
2MST proved to be a reliable and valid physical performance test in patients with TKA. 2MST can be used to evaluate the physical performance of TKA patients.ClinicalTrials.gov Identifier: NCT05064943.
研究 2MST 评估全膝关节置换术（TKA）患者身体表现的重测信度和同时效度。
本研究纳入了 51 名年龄在 18 岁以上、性别不限、至少 6 个月前接受初次 TKA 的 TKA 患者。采用组内相关系数（ICC）和 95%置信区间（CI）、测量标准误差（SEM）和 95%置信水平下的最小可检测变化（MDC）来确定 2MST 的可靠性。在有效性方面，评估了 2MST 与 6 分钟步行测试（6MWT）和 2 分钟步行测试（2MWT）之间的相关性。
2MST 的可靠性非常好（ICC = 0.97，SEM = 2.76，MDC = 7.6）。2MST 与 6MWT 之间存在中度相关性（ = 0.586； = 0.000），与 2MWT 之间也存在中度相关性（ = 0.633； = 0.000）。
2MST 被证明是一种可靠且有效的 TKA 患者身体表现测试。2MST 可用于评估 TKA 患者的身体表现。
