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.
Objective To overview the systematic reviews/meta-analysis (SR/MA) for the effectiveness of yoga on patients with type 2 diabetes mellitus. Methods The CNKI, WanFang Data, VIP, CBM, PubMed, Cochrane Library, Embase, Web of Science, JBI and CINAHL databases were electronically searched to collect SR/MA on the intervention of yoga in diabetes mellitus from inception to November 6th, 2023. Two researchers independently screened the literature and extracted data. AMSTAR was used to evaluate the quality of methodology, and GRADE was used to evaluate the certainty of evidence, and the outcome indicators were statistically analyzed. Results A total of 14 SR/MA were included. The evaluation results of AMSTAR showed that 7 articles were of high quality and 7 articles were of moderate quality. The result of GRADE showed that there were 2 items of high-level evidence, 26 items of intermediate evidence, and the remaining 31 items were low-level or very low-level evidence. The results showed that yoga could significantly reduce fasting blood glucose (FBG) (moderate confidence), glycosylated hemoglobin (HA1C) (moderate confidence) and postprandial blood glucose (PPBG) levels (moderate confidence), and was also superior to other interventions in high-density cholesterol (HDL) (moderate confidence), low-density cholesterol (LDL) (moderate confidence), triglyceride (TG) (moderate confidence), total cholesterol (TC) (moderate confidence), systolic blood pressure (SBP) and diastolic blood pressure (DBP) (moderate confidence), muscle strength (high confidence), cardiorespiratory fitness (moderate confidence) and weight (moderate confidence). Conclusion The existing evidence shows that yoga has a good effect on blood glucose control (moderate confidence) and also has a certain effect on lipid parameters (moderate confidence) and anthropometric indicators (moderate confidence), but the quality and confidence of the current research evidence are low. Future researchers should standardize the research design to provide more high-quality evidence for the prognosis and treatment of type 2 diabetes mellitus.
