Objective  To assess the effectiveness of acupuncture for tension-type headache.
Methods  A systematic review of the relevant randomized controlled trials (RCTs) of acupuncture for tension-type headache was performed using the methods of The Cochrane Collaboration. Trials were collected from The Cochrane Library, Issue 4, 2003, MEDLINE (1966 to March 2004), CBM (1978 to August 2003), VIP (1989 to April 2003) and handsearched all related articles published in Chinese in 2003. The quality of literature was reviewed, and data were extracted by two reviewers independently. Meta-analysis was conducted using RevMan 4.2 software.
Results  Thirteen RCTs involving 571 patients were included, of the thirteen RCTs, six were of high methodological quality according to Jadad scale (the Jadad score≥3), and “sham acupuncture” was used as controlled intervention in eight trials. Meta-analysis indicated that no statistical difference was detected between acupuncture and sham acupuncture groups on effectiveness with RR 1.55, 95%CI 0.97 to 2.47 and P=0.07 at the end of treatment. No statistical difference was detected between acupuncture and sham acupuncture groups on visual analogue scale at the end of treatment with WMD -0.55, 95%CI -1.20 to 0.09 and P=0.09; at the end of follow-up of less than 2 months with WMD -0.22, 95%CI -0.87 to 0.42 and P= 0.50 and at the end of follow-up of more than 2 months with WMD -0.65, 95% CI -1.41 to 0.11 and P=0.09.
Conclusions  Comparing acupuncture with sham acupuncture and other treatments, current evidence can not evaluate whether acupuncture is significantly effective for tension-type headache, more RCTs of high methodological quality are required.
