基于疼痛指数对电针镇痛累积效应的疗效评价

Analgesic Cumulative Effect of Electroacupuncture Based on Pain Index

目的:观察电针镇痛的累积效应及其与记忆的关系。方法:坐骨神经痛病人60例随机分为电针镇痛组(n=30)和电针改善记忆加镇痛组(n=30)。电针镇痛组选穴为足三里、阳陵泉、环跳、委中、肾俞、大肠俞。电针改善记忆加镇痛组选穴足三里、阳陵泉、环跳、委中、肾俞、大肠俞加百会、四神聪。用简化的McGill疼痛问卷测定疗效指标疼痛指数(PPI),治疗前、治疗2天后及1个疗程结束后分别测定疗效指标。结果:电针2天后,与治疗前比较,两组PPI评分无明显差别(P>0.05),电针1个疗程后,两组治疗后PPI评分明显低于治疗前(P<0.05),电针改善记忆加镇痛组PPI评分明显低于电针镇痛组(P<0.05)。结论:重复电针有累积镇痛效应,记忆力的增强在一定程度上增加针刺镇痛的累积效应。

Objective：To observe the cumulative pain effect of electroacupuncture（EA）and to analyze its relation with the memory. Methods：60 cases of sciatica patients were randomly divided into improving memory plus EA analgesia group（n=30）and EA analgesia group（n=30）.EA analgesia group selected the points of Zusanli,Yanglingquan,Huantiao,Weizhong,Shenshu and Dachangshu.Improving memory plus EA analgesia group selected the points of Zusanli,Yanglingquan,Huantiao,Weizhong,Shenshu,Dachangshu plus Baihui and Sishencong.Determination of efficacy endpoints with a simplified McGill Pain Questionnaire,the pain index（PPI）,before treatment,after EA two days,and after EA ten days efficacy endpoint was measured. Results：Compared with before treatment,EA two days later,PPI scores of the two groups were no significant difference（P0.05）,after a course of EA,PPI scores were significantly lower after treatment in both groups than before treatment（P0.05）.PPI score of Improving memory plus EA analgesia group was significantly lower than electroacupuncture analgesia group（P0.05）. Conclusion：Repeated electroacupuncture has a cumulative analgesic effect,and memory enhancements can increase the cumulative effect of acupuncture analgesia to some extent.
