Vincent C. A.The Clinical Journal of Pain: December 1989 ORIGINAL ARTICLE: PDF Only Abstract Abstract: A randomised controlled trial comparing true and sham acupuncture was conducted on 30 patients suffering from chronic migraine. Diary measures of headache and medication intake were recorded throughout the study, and measures of headache quality, anxiety, and pain behaviour were taken. The credibility of the true and sham treatment procedures was also assessed. True acupuncture was significantly more effective than the control procedure in reducing the pain of migraine headache. Posttreatment reductions in pain scores and medication of 43 and 38%, respectively, were recorded in the true acupuncture group and were maintained at 4-month and I-year follow-up. © Lippincott-Raven Publishers.
