Effectiveness of Global Postural Re-Education in Chronic Non-Specific Low Back Pain: Systematic Review and Meta-Analysis

Background: The aim of this systematic review and meta-analysis was to evaluate the global postural re-education (GPR) program's effectiveness compared to other exercise programs in subjects with persistent chronic low back pain. Methods: A systematic review and meta-analysis were carried out using PRISMA2020. An electronic search of scientific databases was performed from their inception to January 2021. Randomized controlled trials that analyzed pain and patient-reported outcomes were included in this review. Four meta-analyses were performed. The outcomes analyzed were disability due to back pain and pain. The risk of bias and quality of evidence were evaluated. The final search was conducted in March. Results: Seven trials were included, totaling 334 patients. The results showed improvement in pain measured by Visual Analogue Scale (VAS) (Standardised Mean Difference (SMD) = -0.69; 95% Confidence Interval (CI), -1.01 to -0.37; p < 0.0001), Numerical Pain Scale (NRS) (SMD = -0.40; 95% CI, -0.87 to 0.06); p = 0.022), VAS + NRS (SMD = -1.32; 95% CI, -1.87 to -0.77; p < 0.0001) and function (Roland Morris Disability Questionnaire (RMDQ)) (SMD = -0.55; 95% CI, -0.83 to -0.27; p < 0.0001) after GPR treatment. Conclusion: This meta-analysis provides reliable evidence that GPR may be an effective method for treating LBP by decreasing pain and improving function, with strong evidence.
