针灸在慢性头痛治疗中的应用——临床荟萃分析

Application of acupuncture in the treatment of chronic headache:A meta-analysis

目的探讨针灸对慢性头痛的治疗效果。方法在Medline(1966-2011),CINAHL,Cochrane Central Register ofControlled Trials与Scopus等数据库中检索所有关于针灸治疗头痛的随机对照研究。研究对象为慢性头痛的成年人,随机接受针灸治疗或者"伪"针灸治疗。其监测指标包括头痛严重程度,头痛的发生频率及患者治疗好转率。结果共17例研究入选,大多数入选的研究显示了针灸治疗慢性头痛较"伪"针灸有效的趋势。荟萃分析显示无论是早期随访阶段还是晚期随访阶段,针灸治疗患者的好转率明显高于对照组:相对危险度(RR)分别为:1.19(95%CI:1.08,1.30)与1.22(95%CI:1.04,1.43)。结论同"伪"针灸相比,针灸可以提高患者的好转率,是一种有效的治疗方法。

To evaluate the efficacy of acupuncture for treatment of chronic headache. Methods The following databases were searched for randomized controlled trials on the use of acupuncture for chronic headache： Medline （ 1966-2011 ）, CINAHL, Cochrane Central Register of Controlled Trials and Scopus. Studies were included if they enrolled adults with chronic headache and were randomized to receive needling acupuncture treatment or sham acupuncture. The data on headache intensity, frequency and response rate were extracted for analysis. Results Seventeen trials were included in this review. The majority of included trials showed a trend in favor of acupuncture. The combined response rate in the acupuncture group was significantly higher as compared with sham acupuncture either at the early follow-up periodl risk ratio（RR）= 1.19, 95% confidence interval（CI） ：1.08- 1. 303 or late follow-up period（RR= 1.22, 95 % CI： 1.04- 1.43 ）. Conclusion Needling acupuncture was superior to sham acupuncture in management of chronic headache.
