低频电刺激拮抗肌对脑卒中患者偏瘫肢体功能的影响

Effect of Low-Frequency Electrical Stimulation to Antagonist Muscles on the Hemiparetic Limb Function in Stroke Patients

目的探讨低频电刺激拮抗肌对脑卒中患者偏瘫肢体功能的影响。方法将96例脑卒中患者随机分为治疗组(48例)和对照组(48例);在治疗前及治疗1个月后对肌张力、运动功能以及日常生活能力进行评估。结果治疗前两组患者Ashworth量表肌张力评定结果、下肢Brunnstrom运动功能和Barthel指数间差异均无统计学意义(u值分别为0.47、0.71和0.41,P>0.05)。治疗1个月后两组患者Ashworth量表肌张力评定结果间差异无统计学意义(u=0.89,P>0.05);两组患者下肢Brunnstrom运动功能和Barthel指数间差异均有统计学意义(u值分别为3.38和5.13,P<0.05)。结论低频电刺激拮抗肌技术在脑卒中偏瘫的治疗中能够促进患者运动功能的恢复,提高患者日常生活能力,是脑卒中康复治疗的非常有效的辅助手段。

Objective To observe the effect of low - frequency electrical stimulation to antagonist muscles on the hemiparetic limb function in stroke patients. Methods Totally 96 stroke patients were randomly divided as trial group （ n = 48 ）, and control group group （ n = 48 ）. Before and after one month treatment, the evaluation of the muscle tone, motor function, and active daily living function was conducted. Results There was no significant difference before treatment in Ashworth Scale score of muscle tone, Brunnstrom motor function of lower extremities and Barthel index between the two groups （ u = 0.47, 0. 71, 0.41, P 〉 0. 05 ）. After one month treatment, between the two groups there was no significant difference in Ashworth Scale score of muscle tone （ u = 0. 89, P 〉 0.05 ）, but there were significant differences in Brunnstrom motor function of lower extremities and Barthel index （ u = 3. 38, 5.13, P 〈 0. 05 ）. Conclusion The low - frequency electrical stimulation to antagonist muscles can promote the recovery of the patients＇ motor function for hemiplegia after stroke, raise the ability of daily life, and it is an auxiliary means very effective in rehabilitation treatment of stroke.
