Acupuncture for the management of chronic headache: a systematic review

Summarized by Hui Xu

In the review article from Department of Anesthesiology, Duke University Medical Center, USA, Doctors and scientists aimed to evaluate the efficacy of acupuncture for treatment of chronic headache.
They searched the databases of Medline (1966-2007), CINAHL, The Cochrane Central Register of Controlled Trials (2006), and Scopus for randomized controlled trials investigating the use of acupuncture for chronic headache. Studies were included in which adults with chronic headache, including migraine, tension-type headache or both, were randomized to receive needling acupuncture treatment or control consisting of sham acupuncture, medication therapy, and other nonpharmacological treatments. They extracted the data on headache intensity, headache frequency, and response rate assessed at early and late follow-up periods.
Thirty-one studies were included in this review. The majority of included trials comparing true acupuncture and sham acupuncture showed a trend in favor of acupuncture. The combined response rate in the acupuncture group was significantly higher compared with sham acupuncture either at the early follow-up period or late follow-up period. Combined data also showed acupuncture was superior to medication therapy for headache intensity , headache frequency, physical function, and response rate.
They concluded that needling acupuncture is superior to sham acupuncture and medication therapy in improving headache intensity, frequency, and response rate.
