OBJECTIVE: To analyze the efficacy of Corrective exercise-based therapy in the improvement of deformity and quality of life in adolescent idiopathic scoliosis. DATA SOURCES: PubMed Medline, Scopus, Web of Science (WOS), Physiotherapy Evidence Database (PEDro), CINAHL Complete and SciELO, until June 2021. REVIEW METHODS: Randomized controlled trials was selected, including participants diagnosed with adolescent idiopathic scoliosis, in which the experimental group received Corrective exercise-based therapy. Two authors independently searched the scientific literature in the data sources, extracted the data and assessed the risk of bias. A pairwise meta-analysis using the random-effects model was performed. RESULTS: Eight randomized controlled trials providing data from 279 adolescent idiopathic scoliosis patients were included. Seven randomized controlled trials including 236 patients showed moderate-quality evidence for a medium effect (SMD -0.52, 95% CI -0.96 to -0.1), favoring corrective exercise-based therapy for spinal deformity reduction. Corrective exercise-based therapy was better than no intervention (SMD -0.59, 95% CI -1.18 to -0.01) but similar to other intervention (SMD -0.2, 95% CI -0.67 to 0.27), and a medium effect was found (SMD -0.51, 95% CI -0.89 to -0.13) when corrective exercise-based therapy was used with other therapies. Four studies including 151 patients showed low-quality evidence of a large effect of Corrective exercise-based therapy on Scoliosis Research Society measurement (SRS-22) total score improvement (SMD 1.16, 95% CI 0.36 to 1.95). CONCLUSION: In mild and moderate adolescent idiopathic scoliosis patients, corrective exercise-based therapy could be used to reduce spinal deformity and to improve quality of life as isolated treatment or as coadjuvant treatment combined with other therapeutic resources.
