表面肌电触发电刺激对脑卒中偏瘫患者下肢运动功能的影响

目的 探讨表面肌电触发电刺激对脑卒中偏瘫患者下肢运动功能的影响.方法 将30例脑卒中偏瘫患者分为治疗组和对照组,每组患者15例.2组患者均给予常规康复训练,治疗组在常规康复训练的基础上给予表面肌电触发电刺激,对照组在常规康复训练的基础上给予低频电刺激.2组患者均于治疗前和治疗3个疗程后进行Brunnstrom运动功能分期、简式Fugl-Meyer(FMA)下肢运动功能评定和表面肌电图肌电积分值(iEMG)测定.结果 3个疗程结束后,2组患者Brunnstrom分期、FAM评分及iEMG较治疗前均有显著提高(P＜0.05),且治疗组各项评分均优于对照组(P＜0.05).结论 表面肌电触发电刺激对脑卒中偏瘫患者下肢运动功能的恢复有明显的促进作用.

The effect of surface electromyogram-triggered electrical stimulation on lower limb function in hemiplegic stroke patients

Objective To study the effect of surface electromyogram-triggered electrical stimulation on lower limb function in hemiplegic stroke patients. Methods Thirty hemiplegic stroke patients were divided into a treatment group ( 15 cases) and a control group ( 15 cases). Both groups were given conventional rehabilitation training.Additionally, the treatment group was given surface electromyogram-triggered electrical stimulation training, while the control group was given common low frequency electrical stimulation. Brunnstrom's recovery stages, the Fugl-Meyer assessment (FMA) and electromyographic parameters were assessed before and after 3 courses of treatment. Results After treatment both groups had significantly higher Brunnstrom and FMA scores and better integrated electromyograms(iEMG), but the effects in the treatment group were significantly better than in the control group. Conclusions Surface electromyogram-triggered electrical stimulation training can provide satisfactory rehabilitation of lower limb function in hemiplegic stroke patients.
