粗大运动功能测试量表66项的反应度和精确度研究

Responsiveness and precision of Gross Motor Function Measure(66 items version)

目的比较粗大运动功能测试量表66项(GMFM 66)与88项(GMFM 88)的反应度和精确度.方法以173例(男性126例、女性47例)接受过两次以上GMFM评估的患儿为研究对象,在平均(3.8±4.3)个月后进行第2次评估,其中112例(64.7%)在平均(3.2±2.2)个月进行第3次评估,比较GMFM 88项和GMFM 66项在前后3次评估之间的效应尺度和相对精确度.结果在各次评估之间,GMFM 66项的效应尺度与GMFM 88项非常接近,差别在0.03～0.04之间,且精确度不低于GMFM 88项.结论具有等距特性的GMFM 66项有良好的反应度和精确度,比GMFM 88项更有利于康复疗效判断.

Objective To compare the responsiveness and precision between the 66 items version of Gross Motor Function Measure （GMFM-66） and 88 items version （GMFM-88）. Methods 173 children with cerebral palsy （male 126, female 47） who have received twice assessments were involved. All the second assessment were performed 3.8±4.3 months later. 112 children received the third assessment 3.2±2.2 months after the second assessment. The effect size and relative precision between the GMFM-66 and GMFM-88 were analyzed. Results The effect size of GMFM-66 between every two assessments was nearly the same as those of GMFM-88. The precision of GMFM-66 was not lower than that of GMFM-88. Conclusion The interval-scale GMFM-66 has satisfying responsiveness and precision. It is more useful than GMFM-88 in measuring the treating effect of children with cerebral palsy.
