【摘要】 目的　评估肌电触发的神经肌肉电刺激在改善偏瘫上肢运动和促进功能恢复方面的效果。方法　选择发病在 4周内的脑卒中患者 60例 ,随机分为治疗组和对照组 ,每组各 3 0例 ,所有受试者均接受神经肌肉促进技术、ADL功能训练 ,治疗组还应用AM 80 0型神经网络重建仪 ,对瘫侧腕伸肌群进行 40min/d肌电触发的神经肌肉电刺激。腕背伸时肌肉最大收缩时肌电幅值 ,伸腕主动关节活动范围 ,腕伸肌力于每次治疗前后均给予测评并记录。此外FMA上肢运动功能积分 ,FIM自我照顾中的进食、梳洗、穿上衣项目 ,在疗程开始与结束时给予评定。结果　治疗后各组观察指标均有不同程度改变 ,经t检验差异具有显著性 (P <0 .0 5 ) ,治疗组与对照组相比 ,经方差分析 ,差异也具有显著性 (P <0 .0 5 )。结论　肌电触发的神经肌肉电刺激治疗早期脑卒中患者 ,上肢运动和功能恢复可获得明显改善更多还原

【Abstract】 Objective To assess the efficacy of electromyogram(EMG) triggered neuromuscular stimulation(EMG stim)in enhancing upper extremity motor and functional recovery of hemiplegia. Methods sixty subjects with stroke of 4 weeks were randomly assigned to either the EMG stim(n=30) or control (n=30) group. All the subjects had a detectable EMG signal(>5 μV) from the surface of the paretic extensor carpi radialis and voluntary wrist extension in synergy or in isolation with muscle grade of <3/5. Subjects of EMG stim group received a 40 minute session per day of wrist strength exercise with EMG stim (experimental), Besides, All the subjects (including experimental and control group) also received various neurodevelopmental techniques (Bobath,PNF etc) for the duration of their rehabilitation stay. EMG amplitude,Muscle strength and ROM of wrist extension were measured before and after treatment every time. Upper extremity Fugl Meyer motor assessment and the feeding, grooming and upper body dressing items of FIM were assessed at study entry and at discharge. Results Subject treated with EMG stim exhibited significantly greater gains in measured items, Fugal meyer and FIM scores compared with controls (P<0.05) . Conclusion These findings indicate that EMG stim enhances the arm function of hemiplegia.更多还原
