BACKGROUND: Exercise therapy was suggested as an appealing treatment option for Adolescent Idiopathic Scoliosis (AIS) patients with less side effects, lower economic costs, and more psychological benefits. Nevertheless, no unanimous findings about the efficacy of exercise therapy have been obtained from previous systematic reviews and/or meta-analyses. OBJECTIVE: To provide an overview of previous systematic reviews and/or meta-analyses on the effectiveness of exercise therapy on AIS treatment. METHODS: Systematic searches in Medline, Eric, CINAHL, Embase, SPORTDiscus, PsycINFO, and the Cochrane Library for systematic reviews and/or meta-analyses of randomized controlled trials (RCTs), non-randomized comparison studies (NRS) or observational studies using exercise as an intervention, and with outcome measures including Cobb angle, angle of trunk rotation (ATR), and quality of life. The methodological quality of the review articles was evaluated by A Measurement Tool to Assess Systematic Reviews (AMSTAR) checklist. RESULTS: Ten systematic reviews and meta-analyses were included. The quality of most of the review articles is moderate with a mean score of 6/11 on the AMSTAR scale. Overall, there is increasing evidence showing the efficacy of exercise therapy on reducing the Cobb angle and angle of trunk rotation, and improving perceived quality of life. CONCLUSION: Exercise therapy was found to have potential benefits to treat physiological and psychological aspects of AIS patients. However, the findings were not conclusive given that some reviews relied on data from the trials with potential risk of bias and significant heterogeneity. More high-quality research is still needed to verify these findings.
