Migraine patients who received true acupuncture had no decrease in headaches as compared with those who received sham acupuncture treatment, according to a study in the May 4 issue of JAMA.
Migraine is a common and disabling condition that typically includes attacks of severe, pulsating, 1-sided headaches, often accompanied by nausea and sensitivity to sound and light, according to background information in the article. Population-based studies suggest that 6 percent to 7 percent of men and 15 percent to 18 percent of women experience migraine headaches. Many patients require interval treatment as attacks occur often or are insufficiently controlled. Drug treatment with beta-blockers, calcium antagonists, or other agents has been shown to reduce the frequency of migraine attacks; however, the success of treatment is usually modest and tolerability often suboptimal. Acupuncture is widely used for preventing migraine attacks although its effectiveness has not yet been fully established.
Klaus Linde, M.D., of the Centre for Complementary Medicine Research, Technische Universität Munich, Germany, and colleagues investigated whether acupuncture reduced headache frequency more effectively than sham acupuncture or no acupuncture in patients with migraines. The study consisted of a three-group, randomized, controlled trial (April 2002-January 2003) involving 302 patients (88 percent women), average age 43 years, with migraine headaches, based on International Headache Society criteria. Patients were randomized to either acupuncture, sham acupuncture, or waiting list control. Acupuncture and sham acupuncture were administered by specialized physicians and consisted of 12 sessions per patient over 8 weeks. The sham treatment consisted of needles placed at non-acupuncture points. Patients were treated at 18 outpatient centers in Germany. Patients completed headache diaries from 4 weeks before to 12 weeks after randomization and from week 21 to 24 after randomization.
