Evaluating the prophylaxis and long-term effectiveness of acupuncture for migraine without aura: study protocol for a...

The instant-treatment effect of acupuncture for patients with migraines has been corroborated in numerous studies. However, most diseases are chronic and tend to recur, so the long-term effect of acupuncture can verify the existence of sustained efficacy or the placebo effect. Evaluating the efficacy of acupuncture in the prophylaxis of migraine without aura (MWoA) in China is also important because such studies are lacking.

This trial is a multicenter, prospective, pragmatic randomized controlled clinical trial. We will randomly allocate 249 participants to three groups of 83. Patients in the individualized acupoint group will be treated with individualized acupuncture point prescriptions. The non-acupoint control group will undergo insertion of acupuncture needles at four bilateral non-points in locations not corresponding to acupuncture points. The waiting-list control group will not undergo treatment but instead will receive 20 acupuncture treatments for free after a waiting period of 24 weeks. Participants in the individualized acupoint group and non-acupoint control group will receive 20 sessions over four weeks and then all participants will receive 20 weeks of follow-up.

The results of our trial will help to supply evidence for the long-term acupuncture effect for MWoA in a long follow-up period, and special attention will be paid to comparison with the placebo effect.

The trial was registered at ClinicalTrials.gov (NCT01687660) on 18 September 2012.
