单侧与双侧上肢经皮穴位电刺激对脑卒中患者上肢功能影响的随机对照研究

Effects of unilateral and bilateral transcutaneous acupoint electrical stimulation on the functional improvement of upper limbs of stroke patients

目的:通过随机对照研究,探讨经皮穴位电刺激(TAES)脑卒中患侧双上肢对患侧上肢功能的影响及可能的机制。方法:29例脑卒中患者根据TAES治疗的部位分为2组,单侧组14名和双侧组15名。两组对象在治疗前分别接受Brunnstrom上肢运动恢复分期(RSB),Fugl-Meyer运动功能评定量表中上肢部分(FMA),手法肌力检查(MMT),改良Ashworth痉挛量表(MAS),改良Barthel指数(MBI)量表评定,在3周治疗后再次评定。结果:两组患者治疗前后各量表评分差异有显著性(P<0.05),两组间各量表评分除MBI评分差异有显著性外,其余4个量表评分差异无显著性(P>0.05),但两组间变化率的比较差异有显著性(P<0.05)。结论:单侧或双侧TAES治疗均能改善脑卒中患者偏瘫上肢的功能,双侧TAES治疗对患侧上肢功能的改善更明显。

Objective：To investigate the effects and mechanism of unilateral and bilateral transcutaneous acupoint electrical stimulation（TAES） on functional improvement of upper limbs of stroke patients. Method：Twenty-nine patients with stroke were randomly divided into two groups. One group （n=14） received TAES treatment on the affected upper limb, the other group （n=15）on bilateral upper limbs.Two groups were evaluated by recovery stage of Brunnstrom（RSB）, Fugl-Meyer motor assessment scale（FMA）, manual muscle test（MMT）, modified Ashworth scale（MAS） and modified Barthel index（MBI） before the first time treatment. After three-week treatment, all patients were evaluated again. Result：There were significant （P〈O.05） changes of scores of all evaluation scales in two groups before and after three-week treatment, and no significant（P〉O.OS）change of scores of 4 assessment scales（except MBI） between two groups, but significant differences were showed in the changes of percentages between two groups（P〈0.05）. Conclusion：Both TAES treatment methods are reliable, but the bilateral treatment is more effective than the unilateral treatment.
