脑瘫儿童精细运动功能测试量表的效度和反应度研究

目的:分析脑瘫患儿精细运动功能测试(FMFM)量表的效度和反应度。方法:共有612例大于6个月的脑瘫患儿参加了本研究,男423例(69.1%),女189例(30.9%);平均年龄(30.6±25.5)个月;其中痉挛型四肢瘫224例(36.6%)、痉挛型双瘫208例(34.0%)、痉挛型偏瘫122例(包括2例单瘫)(19.9%)、徐动型30例(4.9%),肌张力障碍型20例(3.3%),共济失调型8例(1.3%)。分析FMFM量表精细运动能力分值的平行效度(与PDMS-FM原始分的Pearson相关分析)、结构效度(样组间差异分析)和反应度(效应尺度)。结果:FMFM量表精细运动能力分值PDMS-FM量表原始分之间的相关系数为0.95;能有效地区分同一偏瘫患儿健侧和患侧上肢精细运动能力分值之间差异,同时也能有效地区分相同月龄段双瘫和四肢瘫患儿精细运动能力之间的差异;此外本量表具有较好的效应尺度。结论:FMFM量表具有良好的效度和反应度,可以有效地评定脑瘫患儿精细运动能力。

Validity and responsivenes of the fine motor function measure scale for children with cerebral palsy

Objective:To analyze the validity and responsivenes of the Fine Motor Function Measure scale (FMFM for children with cerebral palsy. Method: Six hundred and twelve children with cerebral palsy were involved. 423 males (69.1%) and 189 females,the average age was 30.6 months (SD:25.5months),ranges from 6 to 183 months; Types of CP in the children were spastic quadriplegia (n=224,36.6% ),spastic diplegia (n=208,34.0% ),spastic hemiplegia (n=122,19.9%),athetoid (n=30,4.9%),dystonic (n=20,3.3%),ataxic (n=8,1.3% ).The correlation validity, structural validity of the FMFM were analyzed, as well as the responsiveness. Result: The correlation index between the raw scores of FMFM and Peabody Developmental Motor Scale -Fine Motor was 0.9536. It could be clearly distinguished by FMFM that the fine motor functions between the affected side and the healthy side in children with hemiplegia were different. The difference of fine motor functions between children with diplegia and quadriplegia could also be distinguished by FMFM. The effect size of this scale was also good. Conclusion: The validity and responsiveness of FMFM were satisfying. The fine motor functions of children with cerebral palsy could be effectively measured by FMFM.
