雀啄灸激痛点治疗肌筋膜疼痛综合征:随机对照研究

Myofascial pain syndrome treated with sparrow-pecking moxibustion at trigger points:a randomized controlled trial

目的:比较雀啄灸与针刺激痛点治疗肌筋膜疼痛综合征的疗效差异,为治疗肌筋膜疼痛综合征提供参考。方法:将90例肌筋膜疼痛综合征患者随机分为雀啄灸组和针刺组,每组45例。两组均取疼痛部位的激痛点,雀啄灸组采用雀啄灸疗法,每次艾灸30min;针刺组采用毫针以45°角斜刺激痛点治疗,每次留针40min,两组均每日治疗1次,10次为一疗程。两组治疗1个疗程后,采用简化麦吉尔疼痛量表为观察指标,以治疗前后疼痛分级指数(PRI)、现时疼痛强度(PPI)、视觉模拟评分(VAS)的变化来评价疗效。结果:雀啄灸组和针刺组治疗后PRI、PPI、VAS较治疗前均明显下降(均P<0.001);两组治疗后PRI、PPI、VAS积分比较差异均无统计学意义(均P>0.05)。雀啄灸组愈显率为80.0%(36/45),优于针刺组的40.0%(18/45,P<0.001)。结论:雀啄灸激痛点治疗肌筋膜疼痛综合征疗效优于针刺激痛点,且操作更为简便。

Objective To compare the efficacy difference in treatment of myofasical pain syndrome between sparrow-pecking moxibustion and acupuncture at trigger points so as to provide the reference of the effective therapeutic method for myofascial pain syndrome.Methods Ninety patients were randomized into a sparrow-pecking moxibustion group and an acupuncture group,45 cases in each one.The trigger points were selected in pain areas in the two groups.In the sparrow-pecking moxibustion group,the sparrow-pecking moxibustion was applied,30 min in each time.In the acupuncture group,the filiform needles were inserted obliquely at 45°and retained for40 min in each treatment.The treatment was given once a day and 10 treatments made one session in the two groups.The short-form McGill pain questionnaire was used as the observation index,and the changes in pain rating index（PRI）,present pain intensity（PPI）and visual analogue scale（VAS）before and after treatment were used for efficacy assessment.Results The results of PRI,PPI and VAS after treatment were reduced apparently as compared with those before treatment in the sparrow-pecking moxibustion group and the acupuncture group（all P〈0.001）.The differences in PRI,PPI and VAS after treatment were not significant in comparison of the two groups（both P〉0.05）.The curative and remarkably effective rate was 80.0%（36/45）in the sparrow-pecking moxibustion group,which was better than 40.0%（18/45,P〈0.001）in the acupuncture group.Conclusion Sparrow-pecking moxibustion at trigger points achieves the superior efficacy on myofascial pain syndrome as compared with acupuncture at trigger points.This therapy is simpler in operation additionally.
