目的观察电针镇痛的累积效应。方法将60例坐骨神经痛患者随机分为电针镇痛组(n=30)和安神镇静组(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。安神镇静组选穴足三里、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,采用疼痛分级指数(PRI),于治疗前、治疗2d及疗程结束后分别测定疗效指标。结果治疗2d后与治疗前比较,两组PRI感觉评分、PRI情感评分无明显差异(P〉0.05),治疗1个疗程后,两组PRI感觉评分、PRI情感评分明显低于治疗前(P〈0.05),安神镇静组PRI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,安神镇静(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 accumulative analgesic effect of electroacupuncture. Method Sixty patients with sciatica were randomized into electroacupuncture-analgesia (EA) group (n=30) and mind-tranquilizing (MR) group (n=30). In EA group, Zusanli (ST36), Yanglingquan (GB34), Huantiao (GB30), Weizhong (BL40), Shenshu (BL23), and Dachangshu (BL25) were selected. In MR group, Zusanli (ST36), Yanglingquan (GB34), Huantiao (GB30), Weizhong (BLA0), Shenshu (BL23), Dachangshu (BL25), Baihui (GV20), and Sishencong (EX-HN1) were selected. Therapeutic efficacy was determined by using short-form McGill Pain Questionnaire, and Pain Rating Index (PRI) was also used for evaluation before treatment, after 2-day treatment and at the end of the treatment course. Result After 2-day treatment, the sensory and emotion scores didn't show obvious changes in the two groups (P〉0.05); after 1 treatment course, the sensory and emotion scores were significantly reduced compared to those before treatment in both groups (P〈0.05), and the PRI score in MR group was significantly lower than that in EA group (P〈0.05). Conclusion Repeated electroacupuncture treatment can produce an accumulative analgesic effect, and mind tranquilization (improvement of memory) can enhance the accumulative analgesic effect of acupuncture to some extent.
