Key Takeaway
Consider Schroth training for adolescent idiopathic scoliosis; meta-analysis shows Cobb angle improvement (SMD -0.52).

This systematic review and meta-analysis focused on Schroth training as an intervention for adolescents aged 10–18 years with idiopathic scoliosis. The study population comprised 620 participants, and the primary outcome assessed was the Cobb angle. No comparator was reported in the analysis, and safety outcomes such as adverse events, serious adverse events, discontinuations, or tolerability were not reported.

The authors synthesized findings indicating statistically significant improvements in Cobb angle, with an effect size of SMD = -0.52 and a p-value less than 0.05. The direction of the effect was improvement. Secondary outcomes were not reported in the source data.

Limitations acknowledged by the authors include the lack of reported safety data and the absence of a specified comparator. The review does not provide detailed trial-level information regarding specific adverse events or discontinuation rates. Consequently, the certainty of the findings is tempered by these gaps, and the authors advise cautious interpretation regarding the clinical implementation of these results.

BackgroundAdolescent idiopathic scoliosis (AIS) affects 0.5%–5% of the adolescent population, representing the most common spinal deformity in this age group. This systematic review and meta-analysis aimed to determine optimal exercise prescription parameters for Schroth training in AIS by examining dose-response relationships between exercise frequency, duration, and clinical outcomes.MethodsSystematic searches of PubMed, Scopus, Web of Science, and SPORTDiscus were conducted following PRISMA 2020 guidelines. Randomized controlled trials examining Schroth interventions in adolescents aged 10–18 years with idiopathic scoliosis were included. Network meta-analysis was performed using MetaInsight platform for Cobb angle outcomes, with traditional pairwise meta-analyses conducted for all outcomes using standardized mean differences with 95% confidence intervals.Results15 randomized controlled trials encompassing 620 participants were included. The overall meta-analysis demonstrated Schroth exercises produced statistically significant Cobb angle improvements (SMD = −0.52, p
