瑜伽干预下背痛效果的Meta分析

目的系统评价瑜伽治疗下背痛的有效性。方法计算机检索Web of Science、BBSCO Academic Source Complete、Elsevier ScienceDirect、Scopus、PubMed、WanFang Data和CNKI数据库,搜集有关瑜伽治疗下背痛有效性的随机对照试验(randomized controlled trial,RCT),检索时限均从建库至2019年11月4日。由2名研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后,采用RevMan 5.3软件进行Meta分析。结果共纳入14个RCT,包括1 684例患者。Meta分析结果显示:与常规治疗相比,瑜伽治疗下背痛的RMDQ问卷评分更低MD=–1.86,95%CI(–2.39,–1.33),P<0.000 01],其差异有统计学意义。亚组分析结果显示,不同锻炼频率、下背痛程度、致因、干预周期、样本量等亚组的瑜伽治疗效果均优于常规治疗组,差异均有统计学意义。结论现有证据表明,瑜伽治疗下背痛能取得更好疗效。受纳入研究数量和质量限制,上述结论尚需开展更多高质量研究予以验证。

Efficacy of yoga intervention for low back pain: a meta-analysis

Objectives To systematically review the efficacy of yoga treatment for low back pain. Methods Web of Science, BBSCO Academic Source Complete, Elsevier ScienceDirect, Scopus, PubMed, WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials(RCTs) of yoga intervention for low back pain from inception to November 4 th, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies;then, meta-analysis was performed using RevMan 5.3 software. Results A total of 14 RCTs involving 1 684 patients were included. The results of meta-analysis showed that: compared with conventional treatment, the RMDQ scores of yoga treatment for low back pain was statistically significant lower(MD=–1.86, 95%CI–2.39 to –1.33, P<0.000 01). The results of subgroup analysis showed that the exercise frequency, low back pain degree,low back pain cause, intervention period and sample size had not altered efficacy of yoga. Conclusions Current evidence shows that yoga can achieve superior results in low back pain. Due to limited quality and quantity of the included studies,more high-quality studies are required to verify above conclusions.
