Meta-analysis of Clinical Efficacy of Warm Needling Acupuncture in the Treatment of Lumbar Disc Herniation

[Objectives]To evaluate the efficacy of warm needling acupuncture in the treatment of lumbar disc herniation(LDH)by Meta-analysis.[Methods]Randomized controlled trial of warm needling acupuncture in the treatment of lumbar disc herniation published from January 2000 to December 2021 was searched by Cochrane Library,PubMed,VIP,CNKI and Wanfang.After the quality evaluation of the literature,the Meta-analysis of the literature was carried out by using Review Manager 5.3.[Results]A total of 10 studies were included,involving a total of 980 patients.The results of Meta-analysis showed that warm needling acupuncture in the treatment of lumbar disc herniation could improve the total clinical effective rate,OR=5.38,95%CI(3.40,8.49),P<0.00001;decrease the VAS score,MD=-3.33,95%CI[-4.53,-2.12],z=5.42(P<0.00001);increase the JOA score,MD=-5.63,95%CI[-8.12,-3.14];improve the dysfunction,MD=-5.63,95%CI[-8.12,-3.14],z=4.43(P<0.00001);decrease inflammatory factors,MD=-11.09,95%CI[-13.60,-8.58],z=8.65(P<0.00001).And the recurrence rate was low,OR=0.33,95%CI[0.15,0.70],z=2.86(P=0.004).[Conclusions]Warm needling acupuncture could effectively treat lumbar disc herniation and relieve pain symptoms.However,due to the general poorness of literature quality and the low quality of evidence,high-quality randomized controlled trials are still needed.
