Methods： 275 migraine patients admitted in 3 hospitals were randomly divided into a treatment group treated by EA at Qiuxu （GB 40）, and a control group treated by EA at Tianshu （ST 25）. The indexes of the migraine symptoms and the 5-HT level were observed in both the groups before and after treatment. Results： There was an significant difference in VAS score between the two groups of the 3 clinical centers （P〈0.01）. The therapeutic effects of a 4-week treatment were much better in the treatment group than that of the control group. The 3-month follow-up survey showed that the long-term effects were in favor of the treatment group of the first and third clinical centers, though no significant difference was found in the treatment group of the second clinical center as compared with the control group. The results from the 6-month follow-up survey showed better effects in the treatment group of all the 3 clinical centers. Conclusion： EA at Oiuxu （GB 40） may show effect for migraine.展开更多
