Wolf运动功能测试量表的标准效度和评定者内部信度研究

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。WM丌计时与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。

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

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.
