摘要
目的探讨全髋关节置换术(THA)患者3米后退行走测试(3MBWT)的重测信度、并发效度和最小可检出变化。方法选取29例单侧原发性THA术后患者作为研究对象。所有的评估都是由同一名物理治疗师进行的。每隔1 h评估3MBWT的重测信度，并采用类内相关系数(ICC)进行分析。并发效度分析中，计算3MBWT与Harris Hip Score (HHS)之间的Spearman相关系数。此外，还计算了测量的标准误差(SEM95)和最小可检测变化(MDC95)值。结果患者平均年龄75.6±10.0岁。第二次测试的平均时间比第一次测试快2.41 s。3MBWT的ICC评分为0.983。重测信度非常好。SEM95和MDC95值分别为1.56和4.33。3MBWT的测试和重测评估与HHS相关(p <0.01)。相关程度是中等的。结论3MBWT在原发性单侧THA患者中是一种有效可靠的检测方法。3MBWT的MDC值为临床医生提供了关于患者临床进展的重要信息。
The test-retest reliability, concurrent validity and minimal detectable change of the 3-m backward walking test in patients with total hip arthroplasty
Purpose
To determine the test–retest reliability, concurrent validity and minimal detectable change of the 3-m backward walking test (3MBWT) in patients with Total Hip Arthroplasty (THA).
Methods
A total of 29 patients after unilateral primary THA were enrolled in the study. All evaluations were carried out by the same physiotherapist. The test-retest reliability of the 3MBWT was assessed at an hour interval and analyzed by the Intraclass correlation coefficient (ICC). In the concurrent validity analysis, the Spearman correlation coefficient between 3MBWT and Harris Hip Score (HHS) was calculated. In addition, the standard error of measurement (SEM95) and Minimal Detectable Change (MDC95) values were also calculated.
Results
The mean age of the patients was 75.6 ± 10.0 years. The mean time of the second test was 2.41 s better than the first assessment. The ICC score of 3MBWT was 0.983. Test-retest reliability was excellent. SEM95 and MDC95 values were 1.56 and 4.33, respectively. Both test and retest evaluations of the 3MBWT were correlated with the HHS (p < 0.01). The degree of correlations was moderate.
Conclusion
The 3MBWT is a valid and reliable test in patients with primary unilateral THA. The MDC value of 3MBWT provides essential information to clinicians about patients’ clinical progression.
期刊介绍：
Journal of Arthroscopy and Joint Surgery (JAJS) is committed to bring forth scientific manuscripts in the form of original research articles, current concept reviews, meta-analyses, case reports and letters to the editor. The focus of the Journal is to present wide-ranging, multi-disciplinary perspectives on the problems of the joints that are amenable with Arthroscopy and Arthroplasty. Though Arthroscopy and Arthroplasty entail surgical procedures, the Journal shall not restrict itself to these purely surgical procedures and will also encompass pharmacological, rehabilitative and physical measures that can prevent or postpone the execution of a surgical procedure. The Journal will also publish scientific research related to tissues other than joints that would ultimately have an effect on the joint function.
