Electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis:a randomized controlled trial

电子温灸仪与传统艾灸治疗膝骨关节炎的随机对照试验

Objective:To observe the clinical efficacy of DZWJY-1 type electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis(KOA).Methods:A total of 76 eligible patients were randomized into an electronic moxibustion apparatus group and a traditional moxibustion group,with 38 cases in each group.The electronic moxibustion apparatus group was intervened by DZWJY-1 type electronic moxibustion apparatus,and the traditional moxibustion group received moxa stick moxibustion for treatment.Neixiyan(EX-LE 4),Dubi(ST 35),Xuehai(SP 10)and Liangqiu(ST 34)were selected for both groups and the treatment was conducted 3 times a week for a total of 12 times.The visual analog scale(VAS)and the Western Ontario and McMaster Universities osteoarthritis index(WOMAC)scores were observed before treatment and after 6 and 12 sessions of treatment,respectively.Results:There were 4 dropout cases in the traditional moxibustion group.Therefore,this trial had 72 valid cases,including 38 cases in the electronic moxibustion apparatus group and 34 cases in the traditional moxibustion group,the differences in the baseline data between the two groups were statistically insignificant(P>0.05).After 6 and 12 sessions of treatment,the VAS scores decreased significantly with the increase of treatment sessions in both groups(all P<0.01),and the betweengroup differences were statistically insignificant at the same time points(both P>0.05).The pain intensity was evaluated using the weighted value of VAS score.The markedly effective rate was 47.4%and the total effective rate was 89.5%in the electronic moxibustion apparatus group,versus 50.0%and 94.1%in the traditional moxibustion group,and the betweengroup differences were statistically insignificant(both P>0.05).After 6 and 12 sessions of treatment,the total score and the component scores including pain,stiffness and difficulty moving in the WOMAC decreased significantly with the increase of treatment sessions in both groups(all P<0.01),and the between-group differences were statistically insignificant(all P>0.05).Conclusion:Electronic moxibustion apparatus and traditional moxibustion both are effective in reducing joint pain and improving joint function in KOA patients,and they are equivalent comparing the clinical efficacy.

目的:观察DZWJY-1型电子温灸仪和传统艾灸治疗膝骨关节炎(KOA)的临床疗效.方法:将符合入组标准的76例患者随机分为电子温灸仪组和传统艾灸组,每组38例.电子温灸仪组使用DZWJY-1型电子温灸仪治疗,传统艾灸组采用艾条灸治疗.两组均选取内膝眼、犊鼻、血海和梁丘,每周治疗3次,共治疗12次.观察治疗前、治疗6次后和12次后的视觉模拟量表(VAS)和西安大略与麦克马斯特大学骨关节炎指数(WOMAC)评分.结果:传统艾灸组脱落4例,本试验实际有效病例为72例,即电子温灸仪组38例和传统艾灸组34例,两组各项基线资料无统计学差异(P>0.05).治疗6次和12次后,两组VAS评分均随治疗次数增加而显著下降(均P<0.01),同时间点组间比较差异均无统计学意义(均P>0.05).采用VAS加权值评价疼痛程度.电子温灸仪组的显效率为47.4%,总有效率为89.5%,传统艾灸组的显效率为50.0%,总有效率为94.1%,组间差异均无统计学意义(均P>0.05).治疗6次和12次后,两组WOMAC总分及疼痛、僵直、活动难度的分类评分均随治疗次数增加而显著下降(均P<0.01),组间比较差异均无统计学意义(均P>0.05).结论:电子温灸仪与传统艾灸均能有效减轻KOA患者的关节疼痛,改善关节功能,且电子温灸仪与传统艾灸的临床疗效相仿.
