Trial profile. Participants with a diagnosis of migraine without aura will be recruited at three centers (enrollment areas of Chengdu, Hunan and Chongqing) taking part in the study. All participants should endure a baseline period of four weeks and inappropriate participants will be excluded. A total of 249 participants will be randomized to three groups: individualized acupoint, non-acupoint control, and waiting-list control. Each patient will receive four weeks of treatment and 20 weeks of follow-up. Outcome will be measured before randomization, the week of the last acupuncture session, and 8, 12, 16, 20 and 24 weeks after randomization, except that the acupuncture expectation value will be assessed before randomization, and MSQ, SAS and SDS will be assessed only at four weeks after treatment.
