ObjectivesTo systematically review the efficacy of yoga treatment for low back pain.MethodsWeb 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 4th, 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.ResultsA 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.ConclusionsCurrent 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.
