经皮神经电刺激对弛缓型脑性瘫痪患儿的效果

目的探讨经皮神经电刺激对弛缓型脑瘫患儿的临床疗效及表面肌电变化。方法40 例弛缓型脑瘫患儿分为治疗组(n=20)和对照组(n=20)，两组均接受30 d 的常规康复训练，治疗组另外对股四头肌进行经皮神经电刺激治疗，每周5 次，治疗30d。治疗前后按改良Lovett 肌力测定法进行股四头肌肌力测定(Lovett 分级)，粗大运动功能测试量表(GMFM)评定患儿粗大运动发育情况，同时运用表面肌电仪测定股四头肌自主收缩位表面肌电积分值(iEMG)和表面肌电信号均方根值(RMS)的变化。结果治疗后两组脑瘫患儿的Lovett 分级、GMFM评分、iEMG和RMS均较治疗前改善(P<0.05)，且治疗组优于对照组(P<0.05)。结论经皮神经电刺激有利于提高弛缓型脑瘫患儿股四头肌肌张力，增强肌力，改善运动功能。

Effect of Transcutaneous Electric Nerve Stimulation on Flaccid Cerebral Palsy

Objective To observe the therapeutic effect of transcutaneous electric nerve stimulation on children with flaccid cerebral palsy.Methods 40 children with flaccid cerebral palsy were divided into 2 groups: treatment group(n=20) and control group(n=20).2 groups were given conventional rehabilitation training for 30 d,while the treatment group added transcutaneous electric nerve stimulation on quadriceps femoris for 30 d.Quadriceps femoris was assessed by Modified Lovett classification,gross motor function was assessed by Gross Motor Function Measure(GMFM),and integrated electromyogram(iEMG) and root mean square(RMS) were recorded.Results There was significant improvement in 2 groups in Modified Lovett classification,GMFM,and iEMG and RMS(P<0.05) while the treatment group was better than the control group(P<0.05).Conclusion Transcutaneous electric nerve stimulation can enhance the muscle tone and strength of quadriceps femoris to improve gross motor function for children with flaccid cerebral palsy.
