| 摘 要： | 目的探讨痉挛偏瘫型脑瘫患儿在等长收缩过程中肱二头肌肌张力变化的表面肌电图特征。方法使用表面肌电仪检测10例偏瘫型脑瘫患儿在肱二头肌进行被动等长收缩时的表面肌电信号。结果健侧肌电信号强于患侧,健侧肱二头肌肌电信号的均方根值(RMS)及肌电积分值(iEMG)高于患侧(P<0.05)。结论表面肌电仪对痉挛偏瘫型脑瘫患儿肌张力的评估结果与改良Ashworth量表(MAS)评定结果一致,具有实用价值。

| Abstract: | Objective To explore the surface electromyography(EMG)characteristics of biceps brachii during isometric contraction in children with hemiplegic cerebral palsy.Methods The surface electromyograms signals of biceps brachii of 10 children with hemiplegic cerebral palsy during passive isometric contraction were recorded.Results The intact side registered a stronger EMG than that of the affected side,the integrated electromyography(iEMG)and root mean square(RMS)levels from the intact side were higher than those of affected side significantly(P<0.05).Conclusion The results of electromyographic analysis are consistent with Modified Ashworth Scale.Electromyographic analysis can provide a satisfactory evaluation of the muscle tone in children with hemiplegic cerebral palsy. |
