The effectiveness of visceral osteopathy in pain, disability, and physical function in patients with low-back pain. A systematic review and meta-analysis

Abstract

Background and purposeSystematic review and meta-analysis to assess the effectiveness of visceral osteopathy in improving pain intensity, disability and physical function in patients with low-back pain (LBP). Materials and methodsMEDLINE (Pubmed), PEDro, SCOPUS, Cochrane Library and Web of Science databases were searched from inception to February 2022. PICO search strategy was used to identify randomized controlled trials applying visceral techniques in patients with LBP. Eligible studies and data extraction were conducted independently by two reviewers. Quality of the studies was assessed with the Physiotherapy Evidence Database scale, and the risk of bias with Cochrane Collaboration tool. Meta-analyses were conducted using random effects models according to heterogeneity assessed with I2 coefficient. Data on outcomes of interest were extracted by a researcher using RevMan 5.4 software. ResultsFive studies were included in the systematic review involving 268 patients with LBP. The methodological quality of the included ranged from high to low and the risk of bias was high. Visceral osteopathy techniques have shown no improvements in pain intensity (Standardized mean difference (SMD) = -0.53; 95% CI; -1.09, 0.03; I2: 78%), disability (SMD = -0.08; 95% CI; -0.44, 0.27; I2: 0%) and physical function (SMD = -0.26; 95% CI; -0.62, 0.10; I2: 0%) in patients with LBP. ConclusionsThis systematic review and meta-analysis showed a lack of high-quality studies showing the effectiveness of visceral osteopathy in pain, disability, and physical function in patients with LBP.
