目的探讨经皮电刺激在急性卒中患者穴位应用是否比安慰剂刺激和标准康复治疗更有效地减少痉挛和/或增加肌力。设计随机对照试验。研究对象62例患者，年龄分别为卒中后70.0(标准差7.4)年和9.2(标准差3.4)天。方法将患者随机分为3组，分别接受经皮电刺激组、安慰剂刺激组和标准康复组。刺激患侧小腿4个穴位，60min，每周5天，连续3周。在治疗前、治疗中每周和卒中后8周随访时，测量屈肌痉挛、踝关节肌力和功能活动度。结果治疗前两组患者的预后指标差异无统计学意义。与标准康复或安慰剂刺激相比，经皮穴位电刺激显著增加患者的张力正常率，增加踝背屈肌力量，降低拮抗剂共收缩比(p<；0.05)。经皮电刺激组患者的步行时间也较其他两组提前2~4d。结论经皮电刺激小腿穴位3周，10天内每周电刺激5次，可显著降低踝屈肌痉挛程度，增加背屈肌力，同时减少拮抗剂的共收缩。
OBJECTIVE To investigate whether transcutaneous electrical stimulation, when applied to acupuncture points in patients after acute stroke, decreases spasticity and/or increases muscle strength more effectively than placebo stimulation and standard rehabilitation. DESIGN Randomized control trial. SUBJECTS Sixty-two patients aged 70.0 (standard deviation 7.4) years and 9.2 (standard deviation 3.4) days post-stroke. METHODS The patients were randomly assigned to 3 groups receiving transcutaneous electrical stimulation, placebo stimulation, or standard rehabilitation alone. Stimulation was applied to 4 acupuncture points in the affected lower leg for 60 min, 5 days a week for 3 weeks. Plantarflexor spasticity, ankle muscle strength, and functional mobility were measured before treatment, weekly during treatment, and at follow-up at week 8 post-stroke. RESULTS No significant difference was found in the outcome measures among groups before treatment. When compared with standard rehabilitation or placebo stimulation, transcutaneous electrical stimulation to acupuncture points significantly increased the percentage of patients with normal tone, increased ankle dorsiflexor strength, and decreased antagonist co-contraction ratio (p < 0.05). The patients in the transcutaneous electrical stimulation group also tended to walk 2-4 days earlier than the patients in the other 2 groups. CONCLUSIONS Three weeks of transcutaneous electrical stimulation to lower leg acupuncture points, given 5 times a week within 10 days post-stroke, significantly decreased ankle plantarflexor spasticity, and increased dorsiflexor strength concomitant with a decrease in antagonist co-contraction.
