循经取穴与非循经取穴治疗偏头痛对比研究

摘要

Objective To investigate the different analgesic effects of acupuncture by selecting points along and not along the meridian in treating migraine, analyze the necessity of selecting points along the meridian in the treatment of migraine with acupuncture, and to provide evidence for the acupuncture treatment for migraine.Method Sixty-nine migraine patients were selected as the study subjects and randomized into Shaoyang meridian group, Yangming meridian group and a non-meridian point group by adopting a complete randomized design, 23 cases in each group, to respectively receive acupuncture at the Yuan-primary point of Foot Shaoyang Meridian Qiuxu (GB40), the Yuan-primary point of Foot Yangming Meridian Chongyang (ST42), and a non-meridian point at the midpoint between Qiuxu and Chongyang. Of the three groups, only Shaoyang meridian group selected point along the meridian. The improvements of pain intensity in the three groups were compared, and the pain intensity was measured by using Visual Analogue Scale (VAS). Nonparametric test was used to analyze whether there were significant differences in comparing the improvements of pain in the three groups.Result According to the statistical analyses, the pain intensities were improved significantly in each group (P<0.001), while there were no significant between-group differences in comparing the improvement of pain intensity (P>0.05).Conclusion In the treatment of migraine with acupuncture, selecting points along the meridian and not along the meridian (including non-meridian point) produces equivalent analgesic effect.%目的 了解针刺治疗偏头痛时循经取穴与非循经取穴在镇痛效果上的不同,探讨对偏头痛针刺镇痛治疗时循经取穴的必要性,从而为临床针刺治疗偏头痛选穴提供依据.方法 选取69例偏头痛患者为研究对象,采用完全随机对照设计试验方法,将研究对象随机分为少阳经组、阳明经组、非穴位组3组,每组23例,分别给予针刺足少阳经原穴丘墟穴、足阳明经原穴冲阳穴、丘墟穴与冲阳穴连线中点非穴位处,其中少阳经组为循经取穴,其余两组为非循经取穴.观察比较各组治疗后疼痛程度改善情况,疼痛程度采用疼痛视觉模拟评分表来量化.用非参数检验统计方法统计分析3组疼痛程度改善是否有差异.结果 经统计分析,各组治疗后疼痛程度明显改善,有统计学意义(P<0.001),各组之间疼痛程度改善差异无统计学意义(P>0.05).结论 针刺治疗偏头痛时,循经取穴与非循经取穴(包括非穴位)镇痛效果无明显差异.
