目的 探讨经皮穴位电刺激对脑卒中偏瘫患者上肢运动功能的影响。方法 37例脑卒中患者随机分为TAES组(n=19)和安慰刺激组(n=18)。两组常规治疗相同。TAES组采用KD-2A型经皮神经电刺激治疗仪治疗,刺激部位选择患侧上肢的4个穴位(肩髃、曲池、外关、合谷),频率100 Hz,脉宽0.2 ms,强度以患者最大耐受强度为限;每天治疗1次,每次60 min,连续3周共15次;安慰刺激组接受治疗的部位、时间和疗程与TAES组相同,但每次治疗时没有电流输出。治疗前、治疗第2周、治疗第3周分别用上肢Fugl-Meyer评分和改良Barthel指数评分(MBI)评定上肢运动功能及日常生活活动能力。结果 治疗前,两组患者间的一般情况、FMA-UE 评分和MBI评分的比较差异无统计学意义(P>0.05)。经过治疗,两组患者的FMA-UE和MBI评分与治疗前比较均有改善(P<0.05);TAES组FMA-UE和MBI评分的改善较安慰刺激组明显(P<0.05)。结论 TAES治疗能够提高脑卒中患者上肢运动功能,提高生活自理能力。

Objective To investigate the effect of transcutaneous accupoint electrical stimulation (TAES) in enhancing upper limb function in subjects with stroke. Methods 37 subjects with first stroke were randomly assigned into 2 groups:TAES group(n=19) and placebo stimulation group(n=18). All subjects received the same standard rehabilitation. In the TAES group, Model KD-2A stimulator was applied with 0.2 ms pulses, at 100 Hz within the subject's tolerance level on the 4 acupuncture points (LI15, L I11, LI4, and SJ5) in the affected upper limb for 60 min, 5 days a week for 3 weeks; The time and the course of treatment of the placebo stimulation group were as well as the TAES group's, but no current output for each treatment. All subjects in the 2 groups received standard rehabilitation program. Measurements including Fugl-Meyer motor assessment (FMA-UE) and modified Barthel index(MBI) on affected side were recorded before treatment after 2 and 3 weeks' treatments. Results After 3 weeks treatments,the function scores on affected side of the two groups were improved significantly(P<0.05). And function scores of the TAES group were significantly improved than those of the placebo group (P<0.05). Conclusion Transcutaneous accupoint electrical stimulation significantly may improve the recovery of upper limb function.
