Wolf运动功能测试量表的标准效度和评定者内部信度研究

A study on intrarater reliability and criterion validity of Wolf motor function test

目的:研究脑卒中偏瘫患者上肢运动的Wolf运动功能测试量表(WMFT)的标准效度和评定者内部信度研究。方法:22例脑卒中慢性期患者在2周内由同一测试者进行WMFT的检查,并与Fugl-Meyer评价量表上肢部分进行效度分析。结果:两次WMFT计时组内相关系数(ICC)为0.990,95%置信区间为0.977—0.996;两次WMFT动作质量分级组内相关系数(ICC)为0.988,95%置信区间为0.970—0.995。WMFT计时与WMFT动作质量分级相关系数为-0.971(P<0.001),WMFT计时与FMA上肢评分相关系数为-0.732(P<0.001),WMFT动作质量分级与FMA评分相关系数为0.838(P<0.001)。结论:WMFT具有好的重测信度和标准效度。

Objective：To investigate the validity and the intrarater reliability of the Wolf motor function test （WMFT） for assessing upper limb motor function in stroke patients with hemiplegia. Method： The WMFT was administered to 22 chronic stroke patients twice within 2-week interval by the same rater, and was validated with the upper extremity （UE） component of the Fugl-Meyer motor assessment （FMA）. Result： The intraclass correlation coefficient （ICC） was 0.990, and the 95% confidence interval （CI） was 0.977-0,996 for the performance time of the WMFT. The ICC was 0.988, and the 95% CI was 0.970-0.995 for the functional ability of the WMFT. The correlation coefficient was -0.971 （P〈0.001） between performance time and functional ability of the WMFT. It was -0.732 （P〈0.001） between performance time of the WMFT and UE of the FMA, and 0.838 （P〈0.001） between functional ability of the WMFT and UE of the FMA. Conclusion： The WMFT is an instrument with high test- retest reliability and adequate criterion validity.
