Role of acupuncture in the treatment of migraine.

Since the last Cochrane review of acupuncture and headache in 2001, which found methodological and/or reporting shortcomings in the majority of the studies, several large, randomized trials on the effectiveness of acupuncture as a treatment for headache have been published. Following a brief overview of the pathophysiology of migraine and possible action mechanisms of acupuncture, we look at current studies on acupuncture and migraine and discuss the results. From these results and our own studies on acupuncture and migraine, we conclude that a 6-week course of acupuncture is not inferior to a 6-month prophylactic drug treatment, but that specific Chinese point selection, point stimulation and needling depth are not as important as had been thought. The review suggests that acupuncture should be integrated into existing migraine therapy protocols.
