中文版Fugl-Meyer运动功能评定量表的最小临床意义变化值的研究

A research on the minimal clinically important differences of chinese version of the Fugl-Meyer motor scale

目的建立中文版Fugl-Meyer(FM)运动功能评定量表(上肢部分、下肢部分和总分)用于脑卒中患者运动功能评定的最小临床意义变化值(MCID)。方法同时使用校标法和分布法来确定中文版FM运动功能评定量表的MCID。结果中文版FM运动功能评定量表(上肢部分、下肢部分、总分)的组内重测信度分别为0.997、0.989和0.997,组间重测信度分别为0.993、0.952和0.990,MCID分别为4.58、3.31和6.0。结论通过本研究获得了中文版FM运动功能评定量表的MCID,有助于临床和科研工作人员识别中文版FM运动功能评定量表用于脑卒中患者运动功能疗效评定的变化值的真实性,能够确定是否符合临床意义的变化。

Objective To determine the minimal clinically important differences （ MCID） of chinese version of the Fugl-Meyer（ FM） motor scale for evaluating the motor function of the stroke patients （ upper extremity, lower ex-tremity and total） . Methods The research used anchor-based methods and distribution-based methods together to determine the MCID of chinese version of the FM motor scale. Results The intra-rater retest reliabilities of chinese version of the FM motor scale of motor functions were 0. 997, 0. 989 and 0. 997 for upper extremity, lower extremi-ty, and the total. The inter-rater retest reliabilities were 0. 993, 0. 952 and 0. 990 respectively. The MCID of chi-nese version of FM motor scale were 4. 58 , 3. 31 and 6. 0 . Conclusion The MCID of chinese version of the FM motor scale which could be gained in this study can help both clinical and research staff to identify whether the im-proved effect of motor function, which assessed by chinese version of the FM motor scale, made sense or not in clinical trials or in clinical practice.
