中文摘要：

为了探究双瘫脑性瘫痪儿童下肢肌肉相关性，并分析痉挛特性对双瘫患者下肢肌肉相关性的影响，文章采用表面肌电信号作为信息来源。对12例脑瘫患儿进行下肢腓肠肌和胫骨前肌肌电信号采集以及肌张力测试。信号经过Acqknowledge软件进行滤波处理，所得数据采用SPSS19．0软件进行统计学分析。实验结果表明，痉挛特性减弱了双瘫患儿下肢肌肉相关性。该研究为脑瘫患儿的基础研究及康复训练提供了参考依据。

英文摘要：

In order to explore the correlation of lower-limb muscle of children with diplegia cerebral palsy, and analyze the influence of spasticity on lower-limb muscle relevance of those children, surface electromyography （SEMG） was used as the source of information. In experiment, both SEMG acquisition and muscle tension test of lower limbs gastrocnemius and anterior tibial muscle of twelve cerebral palsy children were carried out. Then, signals were filtered and root-mean-square disposed by Acqknowledge software, and statistical analysis about those obtained data was carried out using SPSS 19.0. The results show that spasticity bate the relevance of lower- limb muscle of children with diplegia cerebral palsy. This research may provide a reference for basic research and rehabilitation training of cerebral palsy children.
