肌电触发电刺激疗法对脑卒中患者手功能的影响

Effects of Electromyography-triggered Stimulation on Hand Function Post Stroke

目的研究肌电触发电刺激疗法对脑卒中患者手功能的影响。方法脑卒中患者40例分为肌电触发电刺激疗法组(肌电触发组)19例,神经肌肉电刺激疗法组21例(NMES组),比较两组治疗前后Fugl-Meyer上肢功能评分、改良Barthel指数、腕背伸主动关节活动度。结果两组患者治疗后各项评分均有显著提高(P<0.001);与NMES组比较,肌电触发组各项评分均有提高(P<0.05)。结论肌电触发电刺激疗法可有效改善偏瘫患者手功能障碍,疗效优于神经肌肉电刺激疗法。

Objective To investigate the effectiveness of electromyography-triggered stimulation on the hand function post stroke. Methods 40 stroke patients were divided into electromyography-triggered stimulation group and neuromuscular electric stimulation group. They were assessed with Fugl-Meyer Assessment （FMA）, active range of motion of wrist extension （WE-AROM） and modified Barthel in- dex （MBI） before and 6 weeks after treatment. Results The scores of all the assessments improved in both groups after treatment （P〈0.001）, and improved more in the electromyography-triggered stimulation group than in the neuromuscular electric stimulation group （P〈0.05）. Conclusion Compared with neuromuscular electrical stimulation, electromyography-triggered stimulation may further improve the hand function post stroke.
