药罐治疗颞下颌关节紊乱病随机双盲对照研究

Effect of Medicated Cupping on Temporomandibular Joint Disorders: A Randomized Controlled Trial

目的 观察中药药罐疗法对颞下颌关节紊乱病(TMD)疼痛的疗效。方法 本研究采用随机双盲设计,选择中国中医科学院西苑医院口腔科来诊的符合入选标准的TMD伴疼痛的患者125例,筛查后入组119例,随机分为治疗组(60例)及对照组(59例),采用拔罐治疗。治疗组采用三七、白芷酒精浸液药罐治疗,对照组采用安慰剂拔罐,隔日治疗1次,5次为1疗程,共2疗程。观察主观指标视觉模拟量表(VAS)值、客观指标Fricton指数和压痛值,评价药罐疗法对TMD的短期临床疗效。结果 两组共完成治疗112例,与本组治疗前比较,两组TMD疼痛患者治疗后VAS均降低(P<0.05),压痛值均升高(P<0.05)。治疗组治疗后VAS低于对照组(P<0.05),压痛值高于对照组(P=0.001)。治疗组总有效率[93%(53/57)]优于对照组[76%(42/55)],差异有统计学意义(P<0.05)。结论 药罐疗法治疗TMD疗效确切。

Objective To observe the therapeutic effect of medicated cupping on temporomandibular joint disorder(TMD). Methods A double-blinded randomized controlled trial was performed. Totally 125 patients with TMD with pain were screened from the Department of Stomatology of Xiyuan Hospital of China Academy of Chinese Medical Sciences,and 119 cases were enrolled after screening. The patients were randomly assigned to treatment group(60 cases) and control group(59 cases),the treatment group was treated with Panax notoginseng and Angelica dahurica alcohol extract cupping,and the control group was treated with placebo cupping,once every other day,five times as a course of treatment,both groups received two courses of treatment. The subjective indicator visual analog scale(VAS) value,objective indicators involving fricton index and tenderness value were observed to evaluate the short-term clinical efficacy of medicated cupping on TMD.Results Totally 112 cases completed the trial,compared with baseline,the VAS in the two groups decreased(P<0.05), and the tenderness value increased(P< 0.05). After treatment,VAS was lower in the treatment group than that in the control group after treatment(P<0.05), and pressure pain values were higher than that in the control group(P=0.001).The total effective rate of treatment group was better than that in the control group[93%(53/57) vs. 76%(42/55),P<0.05]. Conclusion Medicated cupping is effective for temporomandibular joint disorder.
