Many randomized controlled trials (RCTs) about motion style acupuncture in the treatment of acute nonspecific low back pain (ANSLBP) have been published recently, but there is no new systematic evaluation for effectiveness and safety of this treatment in ANSLBP.

To systematically evaluate the effectiveness and safety of motion style acupuncture in treating ANSLBP by meta-analysis.

RCTs, crossover studies or cohort studies about effectiveness and safety of motion style acupuncture in treating ANSLBP were retrieved in electronic databases of CNKI, CBM, Wanfang Data, VIP, PubMed, the National Library of Medicine, Embase and the Cochrane Central Register of Controlled Trials from inception to March 25th, 2021. Revman 5.3 was used to complete the Meta-analysis.

All the finally enrolled 17 articles used a design of RCT, including 1 226 patients, and 610 of them were treated with motion style acupuncture (observation group) , and other 616 patients were treated with positive control, blank control, placebo acupuncture or dummy acupuncture (control group) . Meta-analysis showed that, compared with controls treated with Western medicine, the observation group had significantly lower post-treatment VAS score〔MD=-1.54, 95%CI (-2.43, -0.65) , P=0.000 7〕, and Roland-Morris Disability Questionnaire (RMDQ) score〔MD=-3.08, 95%CI (-4.92, -1.24) , P=0.001〕, and significantly higher post-treatment ROM of lumbar vertebra〔MD=-1.42, 95%CI (-1.62, -1.22) , P<0.000 01〕and overall response rate〔RR=1.27, 95%CI (1.19, 1.35) , P<0.000 01〕, but there was no significant difference in post-treatment ODI score between the two groups〔MD=-5.11, 95%CI (-19.12, 8.91) , P=0.48〕. Compared with controls treated with dummy acupuncture, the observation group had significantly lower post-treatment VAS score〔MD=-1.70, 95%CI (-2.05, -1.35) , P<0.000 01〕and RMDQ score〔MD=-3.06, 95%CI (-4.50, -2.70) , P<0.000 01〕. Compared with controls treated with physical therapy, the observation group had significantly lower post-treatment VAS score〔MD=-1.60, 95%CI (-2.06, -1.14) , P<0.000 01〕and RMDQ score〔MD=-3.00, 95%CI (-4.31, -1.69) , P<0.000 01〕. Compared with controls treated with Tuina, the observation group had significantly lower post-treatment VAS score〔MD=-1.50, 95%CI (-1.65, -1.35) , P<0.000 01〕, and significantly higher overall response rate〔RR=1.19, 95%CI (1.09, 1.30) , P=0.000 1〕. Only one RCT reported that the incidence of adverse events in observation group was 13.33% (4/30) during treatment.

Available documentary evidence showed that, motion style acupuncture can effectively relieve the pain and lumbar dysfunction, and improve the ROM of lumbar vertebra and overall response rate in patients with ANSLBP, with high safety, but which still needs to be confirmed by more high-quality, large-sample RCTs.

近年陆续出现了多项运动针法治疗急性非特异性腰痛（ANSLBP）的随机对照试验（RCTs），但尚缺乏新的关于运动针法治疗ANSLBP有效性和安全性的系统评价。

通过Meta分析方法系统评价运动针法治疗ANSLBP的有效性和安全性。

计算机检索中国知网（CNKI）、中国生物医学文献数据库（CBM）、万方数据知识服务平台（Wanfang Data）、维普网（VIP）、PubMed、the National Library of Medicine（MEDLINE）、Embase、the Cochrane Central Register of Controlled Trials（CENTRAL），筛选运动针法治疗ANSLBP有效性和安全性的RCTs、交叉研究、队列研究，检索时间为数据库建立至2021-03-25。采用Revman 5.3软件完成Meta分析。

最终纳入的17篇文献研究类型均为RCTs，共涉及1 226例患者，其中观察组610例，采用运动针法治疗；对照组616例，采用阳性对照或空白对照/安慰针/假针。Meta分析结果：（1）运动针法对照西药，观察组患者治疗后视觉模拟评分法（VAS）评分〔MD=-1.54，95%CI（-2.43，-0.65），P=0.000 7〕、Roland-Morris腰椎功能障碍调查表（RMDQ）评分〔MD=-3.08，95%CI（-4.92，-1.24），P=0.001〕低于对照组，腰椎关节活动度（ROM）大于对照组〔MD=-1.42，95%CI（-1.62，-1.22），P<0.000 01〕，总有效率高于对照组〔RR=1.27，95%CI（1.19，1.35），P<0.000 01〕，但两组患者治疗后Oswestry功能障碍指数（ODI）评分比较，差异无统计学意义〔MD=-5.11，95%CI（-19.12，8.91），P=0.48〕；（2）运动针法对照假针，观察组患者治疗后VAS评分〔MD=-1.70，95%CI（-2.05，-1.35），P<0.000 01〕、RMDQ评分〔MD=-3.06，95%CI（-4.50，-2.70），P<0.000 01〕低于对照组；（3）运动针法对照物理治疗，观察组患者治疗后VAS评分〔MD=-1.60，95%CI（-2.06，-1.14），P<0.000 01〕、RMDQ评分〔MD=-3.00，95%CI（-4.31，-1.69），P<0.000 01〕低于对照组；（4）运动针法对照推拿，观察组患者治疗后VAS评分低于对照组〔MD=-1.50，95%CI（-1.65，-1.35），P<0.000 01〕，总有效率高于对照组〔RR=1.19，95%CI（1.09，1.30），P=0.000 1〕。1篇文献报道观察组患者治疗期间不良事件发生率为13.33%（4/30）。

现有文献证据表明运动针法能有效减轻ANSLBP患者疼痛、腰椎功能障碍，提高患者腰椎ROM及总有效率，且安全性较高，但仍需更多大样本、高质量RCTs进一步证实。
