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SPSS 19.0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。 In order to explore the correlation of lower extremity muscles in children with bipolar cerebral palsy, and to analyze the effect of spasticity on lower extremity muscle relatedness in patients with bipolar disorder, the paper uses surface EMG as a source of information. Twelve cases of cerebral palsy children with gastrocnemius muscle and tibialis anterior muscle EMG signal acquisition and muscle tone test. The signal was filtered by Acqknowledge software, and the data was analyzed by SPSS 19.0 software. The experimental results show that spasticity weakens the lower extremity muscle in children with double paralysis. The study provides a reference for the basic research and rehabilitation training of children with cerebral palsy.
