背景情况:

简化中文下肢功能尺度 (SC-LEFS) 评估了下肢肌肉骨疾病的中文患者的功能.
以前的研究还没有评估SC-LEFS在非关节炎肌肉骨损伤中的可靠性和响应性.

研究的目的:

为了确定SC-LEFS的测试-重新测试可靠性的最小可检测变化 (MDC).
为了确定SC-LEFS的响应能力的实质性临床益处 (SCB).
评估这些措施在患有非关节炎下肢肌肉骨损伤的患者.

主要方法:

一组763名患有非关节炎下肢损伤的患者 (年龄在18-50岁) 在基线和4周完成了SC-LEFS.
用"稳定"组 (n=40) 来计算MDC的测试-重试可靠性进行了评估.
通过比较"改善" (n=497) 和"没有改善" (n=266) 组来评估响应度,以确定SCB.

主要成果:

测试重复测试可靠性很好,类内相关系数为0.98和MDC为5.1分.
对响应能力的SCB值被确定为9.5点.
该SC-LEFS表现出良好的能力来区分改善和未改善的患者 (AUC=0.75).

结论:

对于非关节炎下肢肌肉骨损伤的华语患者来说,SC-LEFS是可靠的和响应的.
一个MDC的5.1分表示测量误差.
在SC-LEFS上的9.5个点的改善意味着在4周的时间内临床上有意义的变化.
