Efficacy of Acupuncture for Acute Migraine Attack: A Multicenter Single Blinded, Randomized Controlled Trial

OBJECTIVE: We aim to investigate the efficacy of acupuncture for acute migraine attacks comparing with sham acupuncture. DESIGN: The study was designed as a multicenter, single-blinded, randomized controlled clinical trial. SETTING AND PATIENTS: From March 2007 to February 2009, 150 patients were randomly allocated to verum or sham acupuncture group in a ratio of 1:1. INTERVENTIONS: Every patient received a verum or sham acupuncture treatment when having a migraine attack and, medications were allowed if the pain failed to be relieved two hours after the acupuncture. OUTCOME MEASURES: The primary outcome was visual analog scale (VAS) scores for pain, ranging from 0 (no pain) to 10 (worst pain ever). RESULTS: The mean VAS scores 24 hours after treatment decreased from 5.7 ± 1.4 to 3.3 ± 2.5 in the verum acupuncture group, and from 5.4 ± 1.3 to 4.7 ± 2.4 in the sham acupuncture group. Significant differences existed between the two groups (P = 0.001). CONCLUSIONS: This trial suggested that verum acupuncture group was superior to sham acupuncture group on relieving pain and reducing the usage of acute medication.
