How effective is acupuncture for prophylaxis of migraine?
Fourteen trials compared a “true” acupuncture intervention with a variety of sham interventions. Pooled analysis did not show a statistically significant superiority for true acupuncture for any outcome in any of the time windows, but the results of single trials varied considerably. The correct placement of needles seems to be less relevant than is usually thought by acupuncturists.
Migraine is a disorder with recurrent headaches manifesting in attacks lasting 4 to 72 hours. It is a common disorder, with a 1-year prevalence of about 10% to 12% and a lifetime prevalence of between 15% and 20%.1 Acupuncture is often used for migraine prophylaxis but its effectiveness is still controversial.
