目的 探讨经皮穴位电刺激对脑卒中偏瘫患者下肢功能的影响。方法 41例脑卒中患者随机分为TAES组和安慰刺激组,分别为21例和20例。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,刺激部位选择患侧下肢的4个穴位(足三里ST 36、太冲LV 13、阳陵泉GB 34、昆仑BI 60),频率100 Hz,脉宽0.2 ms,强度为患者最大耐受强度为限;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2周、治疗3周分别用综合痉挛量表(CSS)评定踝关节痉挛,Fugl-Meyer运动评定量表中下肢部分(FMA)评定下肢运动功能,Berg平衡量表(BBS)评定平衡功能。结果 组内比较:治疗2周和治疗3周后与治疗前比较两组CSS、FMA下肢部分、BBS评分差异有统计学意义(P<0.05);组间比较:治疗2周和3周后,TAES组CSS、FMA、BBS评分优于安慰刺激组,差异有统计学意义(P<0.05)。结论 TAES治疗能减轻脑卒中患者偏瘫下肢痉挛程度和提高平衡功能,改善下肢运动能力。

Objective To investigate the effect of transcutaneous accupoint electrical stimulation(TAES)in enhancing motor and functional recovery of the lower extremity in subjects with stroke. Methods 41 subjects with first stroke were randomly assigned into 2 groups:TAES group and placebo stimulation group.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(ST 36,LV 3,GB 34,and Bl 60)in the affected lower legs for 60 min,5 days a week for 3 weeks;The time and the course of treatment of the placebo stimulation group was 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 composite spasticity score(CSS)for the spasticity of the ankle planter flexors,Fugl-Meyer motor assessment(FMA)for the lower extremity,and Berg Balance Scale(BBS)for balance were recorded before treatment,after 2 and 3 weeks' treatment. Results After 2 and 3 weeks of treatment,the CSS score in the TAES group was significantly lower than the placebo stimulation group(P<0.05)and the FMA score and BBS score in the TAES group was significantly higher than the placebo stimulation group(P<0.05). Conclusion Transcutaneous accupoint electrical stimulation significantly decreased ankle plantar flexor spasticity and improve motor function of the affected lower extremity.

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.
