[Survey on clinical evidence of acupuncture therapy for fibromyalgia syndrome].

To evaluate the clinical effect of acupuncture therapy for fibromyalgia syndrome (FMS) by analyzing the available studies so as to provide clinical decision-making reference.

METHODS:
The published papers on clinical trails for acupuncture treatment of FMS were widely retrieved from Chinese Biomedical Databases (1979 - 2010), www. cnki. net (1979-2010), VIP China Scientific Journal Database (1989- 2010), Digital Periodicals on Wanfang Data (1998 - 2010), PubMed (1966-2010), etc. and by using key words of fibromyalgia syndrome and acupuncture. According to criterion of evidence-based medicine, the evidence from high to low quality levels was selected to answer corresponding clinical questions, and software RevMan 5.0 was used to analyze the final results.

RESULTS:
There has been no enough clinical evidence showing definite efficacy of acupuncture for FMS. However, a Level-A study (being in line with conditions of large sample, multi-centers, randomized controlled trails) and a level-C study (having control group, but without distinct randomizing method) showed respectively that acupuncture might be superior to Amitriptyline and Brufen in relieving FMS. Moreover, a piece of evidence that acupuncture combined with western medicine was superior to western medicine alone was allocated to a level-B (having correct randomizing method and control group). Finally, only a level-C evidence proved that laser irradiation on acupoint might be superior to traditional acupuncture in improving FMS.

CONCLUSION:
Acupuncture for FMS has a positive effect, and acupuncture combined with western medicine can strengthen the curative effect. However this conclusion should be proved further by randomized controlled double blind clinical trials with large samples.
