摘　　要：目的探讨肌电触发电刺激对脑卒中偏瘫患者痉挛性足下垂的影响。方法 36例脑卒中偏瘫患者随机分为常规组和肌电触发电刺激组(触发组),并于治疗前后分别采用常规临床评价方法和表面肌电仪进行评估。结果治疗后两组Fugl-Meyer评分、关节活动度、最大用力背伸i EMG(integrated electromyography)和协同收缩率较治疗前均有所改善(P<0.05),且触发组优于常规组(P<0.05)。结论肌电触发电刺激可增强脑卒中患者肌力,改善协同收缩率,纠正足下垂。Objective To investigate the effect of EMG-triggered stimulation on drop foot for poststroke hemiplegia. Methods 36 hemiplegic patients were randomized into routine group（n=18） and EMG-triggered stimulation group（triggered group, n=18）. 2 groups were assessed by Fugl-Meyer Assessment（FMA）, range of motion（ROM） of ankle dorsiflexion and i EMG values before and after treatment. Results The scores of FMA, degrees of ROM, iEMG values of the tibialis anterior, and co-contraction ratio improved in 2 groups after treatment（P〈0.05）, and the triggered group had better effect than the routine group（P〈0.05）. Conclusion EMG- triggered stimulation can improve muscle strength, and decrease co-contraction ratio.
