基于红外线热成像技术定位针刺肌筋膜触发点治疗腰背肌筋膜疼痛综合征的临床疗效

Clinical efficacy of acupuncture myofascial trigger point in the treatment of low back myofascial pain syndrome based on infrared thermal imaging technique

目的观察基于红外线热成像技术定位针刺肌筋膜触发点治疗腰背肌筋膜疼痛综合征的临床疗效。方法选取2018年6月—2019年6月广西中医药大学附属瑞康医院诊治的60例MPS患者,按随机数字表法分为治疗组及对照组各30例,治疗组运用红外线热成像诊断技术定位并针刺灭活肌筋膜触发点,对照组则定位传统腧穴进行针刺,2组患者均隔天治疗1次,每周3次,共治疗2周,疗程结束后观察2组患者治疗前后红外线热成像分布图、McGill简化量表疼痛评分及临床疗效。结果2组患者治疗前疼痛分级指数(PRI)评分、视觉模拟评分法(VAS)评分及现有痛强度(PPI)评分比较(t=-0.399、-0.454、-0.210),差异均无统计学意义(均P>0.05);2组患者治疗后PRI、VAS及PPI评分均较同组治疗前降低,差异均具有统计学意义(均P<0.05),治疗后2组间PRI、VAS及PPI评分差异具有统计学意义(均P<0.05),且在改善程度上治疗组患者相对于对照组更为明显;同时治疗组腰背部高温区较治疗前明显降低,分布亦减少,而对照组腰背部高温区较治疗前亦有降低,分布亦减少,但与观察组相比在高温区及分布减少程度上仍有一定差距。结论通过红外线热成像图对肌筋膜触发点进行定位后针刺灭活治疗腰背部肌筋膜疼痛综合征是一种有效、快速、精准的治疗方法,值得临床推广应用。

Objective To observe the clinical efficacy of acupuncture myofascial trigger point in the treatment of low back myofascial pain syndrome(MPS)based on infrared thermal imaging technique.Methods According to the inclusion criteria and exclusion criteria,60 patients with MPS were randomly divided into treatment group(n=30)and control group(n=30).The treatment group was treated with infrared thermal imaging to locate and acupuncture the trigger points of inactivated muscle and fascia,while the control group was treated with acupuncture at traditional acupoints.Patients were treated once every other day,3 times a week for 2 weeks.After the course of treatment,the infrared thermal imaging distribution map,McGill simplified scale pain score and clinical curative effect analysis were observed before and after treatment.Results There was no significant difference in PRI score,VAS score and PPI score between the two groups before treatment(t=-0.399,-0.454,-0.210),all P>0.05.The scores of PRI,VAS and PPI in the two groups after treatment were significantly lower than those in the same group before treatment,and there were significant differences in the scores of PRI,VAS and PPI between the two groups after treatment,and the degree of improvement in the treatment group was more obvious than that in the control group.At the same time,the high temperature area of low back in the treatment group was significantly lower than that before treatment,and the distribution of the high temperature area in the control group was also lower than that before treatment,but there was still a certain gap between the treatment group and the observation group.Conclusion Acupuncture inactivation after locating the myofascial trigger point by infrared thermography is an effective,rapid and accurate method for the treatment of low back myofascial pain syndrome,which is worthy of clinical application.
