Evaluation Of Clinical Effectiveness Of Acupuncture For Migraine On The Basis Of Evidence-Based Medicine

EBM (Evidence-based medicine) is developing rapidly among international medical field. It has great improvement for the transition of traditional medical concept and provides scientific guidance for clinical practice and decision. Acupuncture is widely used for the treatment of migraine, but its effectiveness can't be confirmed fully in the systematic review of EBM. This article made an analysis and considered the conclusion is due to the disparity between methodology quality of current acupuncture for migraine clinical research and the criteria of EBM. Thus we conducted such a clinical study.Objectives: To evaluate the effectiveness of acupuncture for migraine on the basic requirement of EBM (Evidence Based Medicine) for clinical trials.Methods: Using random numbers table, 48 patients were randomly assigned into acupuncture group and control group, which took sham acupuncture as placebo. Double blindness was adopted in evaluation through VAS (visual analog scale) and comprehensive marks.Results: (1) After the first treatment, the VAS points in acupuncture group decreased remarkably. There were significant difference between the two groups (P<0.01) . (2)Qne month later after the treatment, there were significant difference between the two groups in comprehensive marks (P<0.01) .The total effective rate in acupuncture group was 84% and in sham acupuncture group was 21.74%. (3)In the follow-up conducted six months later after the treatment, it show the effective rate declined in both groups. However there were still distinct difference between them (P<0.05) .Conclusion: (1) Acupuncture has instant pain-relief effects for migraine. (2)Acupuncture can decrease or reduce the frequency, intensity, duration and concomitant symptoms of migraine attacks. Its near result was positive. (3)The late result of acupuncture for migrainedeclined. But acupuncture was still superior to sham acupuncture. (4)The placebo effects couldn't be excluded from acupuncture .But comparing with sham acupuncture, acupuncture, the intervention itself, is the determinative factor to yield curative effects for migraine.
