电针太阳穴治疗偏头痛肝阳上亢证即时镇痛效应研究

目的:探讨电针与药物治疗偏头痛肝阳上亢证的效应差异。方法:采用3中心随机对照研究方法,将300例患者随机纳入治疗组和对照组各150例,分别给予电针太阳穴和口服西药治疗,观察治疗前后头痛强度评分、头痛缓解度和缓解率的变化。结果:两组患者针刺或服药1次后,头痛强度的VAS评分呈动态降低趋势,治疗组治疗后3～4小时头痛强度评分达最低值,且降低的幅度大于对照组(P<0.01);两组患者头痛缓解持续时间分别为(388.6±430.1)分钟和(163.3±182.3)分钟,治疗组显著长于对照组(P<0.01);缓解率分别为80.1%、76.4%,组间比较差异无显著性意义(P>0.05)。结论:电针太阳穴治疗偏头痛肝阳上亢证具有肯定的即时镇痛效应,其在效应的维持上优于常规西药治疗。

Transient analgesic effect of electroacupuncture at Taiyang (EX-HN 5) for treatment of migraine with hyperactivity of the liver-yang

OBJECTIVE: To explore the difference of therapeutic effects between electroacupuncture (EA) and medication for treatment of migraine with hyperactivity of the liver-yang. METHODS: With 3-center randomized controlled study method, 300 cases were assigned to a treatment group and a control group, 150 cases in each group. They were treated respectively with EA at Taiyang (EX-HN 5) and oral administration of western medicine. Changes of the score for headache intensity, remission degree of headache and remission rate of headache after treatment were investigated. RESULTS: After once treatment, VAS score of the headache intensity showed dynamical decrease in the two groups; in the treatment group the score reached the lowest 3-4 h after treatment, with the decreasing degree better than the control group (P < 0.01). The lasting time of headache remission was (388.6 +/- 430.1) min and (163.3 +/- 182.3) min, respectively, the treatment group being significantly longer than that of the control group (P < 0.01). CONCLUSION: EA at Taiyang (EX-HN 5) has transient analgesic effect for treatment of migraine with hyperactivity of the liver-yang, which is better than that of routine western medication.
