Effects of GPR on Non-Specific Chronic Low Back Pain

Introduction: Low back pain affects approximately 18.5% of the Brazilian population in adulthood, significantly impacting the quality of life and generating substantial costs for the health system. The Global Postural Reeducation Method (GPR) is a promising therapeutic alternative due to its multidimensional approach, capable of improving postural control and reducing pain. Objectives: to evaluate the Efficacy of the RPG method compared to simulated RPG (SHAM) in treating patients with chronic nonspecific low back pain. Methods: Randomized sham-controlled clinical trial. Forty-two adult individuals with chronic nonspecific low back pain will be recruited and distributed into two groups: the Experimental Group (EG), which will receive GPR sessions, and the Control Group (CG), which will receive RPG-SHAM sessions. Both groups will be treated for 30 minutes once a week for 8 weeks. Descriptive analysis will be performed, continuous variables will be summarized to the mean, and standard deviation and categorical variables will be summarized as absolute and relative frequencies. To assess the effects of the intervention over team, analysis of variance (ANOVA) with repeated measures will be used, with a significance level of 5% (p \< 0.05). Expected Results: This study is expected to provide robust evidence on the effectiveness of RPG in treating patients with low back pain, contributing to a better understanding of this complex health condition. The results will potentially positively impact the clinical practice of Orthopedic Physiotherapy, offering an exercise-based and accessible approach for treating patients with low back pain.
