Yoga is being increasingly studied as a treatment strategy for a variety of different clinical conditions, including low back pain (LBP). We set out to conduct an evidence map of yoga for the treatment, prevention and recurrence of acute or chronic low back pain (cLBP).
We searched Medline, Cochrane Database of Systematic Reviews, EMBASE, Allied and Complementary Medicine Database and ClinicalTrials.gov for randomized controlled trials (RCT), systematic reviews or planned studies on the treatment or prevention of acute back pain or cLBP. Two independent reviewers screened papers for inclusion, extracted data and assessed the quality of included studies.
Three eligible systematic reviews were identified that included 10 RCTs (n=956) that evaluated yoga for non-specific cLBP. We did not identify additional RCTs beyond those included in the systematic reviews. Our search of ClinicalTrials.gov identified one small (n=10) unpublished trial and one large (n=320) planned clinical trial. The most recent good quality systematic review indicated significant effects for short- and long-term pain reduction (n=6 trials; standardized mean difference [SMD] -0.48; 95% CI, -0.65 to -0.31; I(2)=0% and n=5; SMD -0.33; 95% CI, -0.59 to -0.07; I(2)=48%, respectively). Long-term effects for back specific disability were also identified (n=5; SMD -0.35; 95% CI, -0.55 to -0.15; I(2)=20%). No studies were identified evaluating yoga for prevention or treatment of acute LBP.
Evidence suggests benefit of yoga in midlife adults with non-specific cLBP for short- and long-term pain and back-specific disability, but the effects of yoga for health-related quality of life, well- being and acute LBP are uncertain. Without additional studies, further systematic reviews are unlikely to be informative.
瑜伽作为一种治疗策略，正在越来越多地被研究用于治疗多种不同的临床病症，包括下背痛（LBP）。我们旨在进行一项瑜伽治疗、预防和复发急性或慢性下背痛（cLBP）的证据图谱。
我们检索了 Medline、Cochrane 系统评价数据库、EMBASE、辅助和补充医学数据库以及 ClinicalTrials.gov，以查找治疗急性背痛或 cLBP 的随机对照试验（RCT）、系统评价或计划研究。两名独立评审员筛选纳入的论文，提取数据并评估纳入研究的质量。
确定了三项合格的系统评价，其中包括 10 项 RCT（n=956），评估了瑜伽对非特异性 cLBP 的疗效。除了系统评价中包括的 RCT 之外，我们没有发现其他 RCT。我们对 ClinicalTrials.gov 的搜索发现了一项小型（n=10）未发表的试验和一项大型（n=320）计划临床试验。最近的高质量系统评价表明，短期和长期疼痛减轻均有显著效果（n=6 项试验；标准化均数差 [SMD] -0.48；95%置信区间，-0.65 至-0.31；I²=0%和 n=5；SMD -0.33；95%置信区间，-0.59 至-0.07；I²=48%）。还确定了长期对背部特定残疾的影响（n=5；SMD -0.35；95%置信区间，-0.55 至-0.15；I²=20%）。没有研究评估瑜伽对急性 LBP 的预防或治疗作用。
证据表明，瑜伽对非特异性 cLBP 的中年成年人具有短期和长期缓解疼痛和背部特定残疾的益处，但瑜伽对健康相关生活质量、幸福感和急性 LBP 的影响尚不确定。在没有更多研究的情况下，进一步的系统评价不太可能提供信息。
