Thirty-one adolescents diagnosed with idiopathic scoliosis were randomized to receive either Schroth exercises (n=15) or Lyon exercises (n=16) over six months. The primary outcome was the improvement in Cobb angle. Secondary outcomes included angle of trunk rotation (ATR), quality of life by scoliosis research society-22, and perceived trunk appearance assessed through validated tools. Outcomes were measured at baseline and post-treatment. Overall, Schroth exercises significantly improved Cobb angle, ATR, and perceived trunk appearance compared to Lyon exercises. However, Lyon exercises led to better improvement in QoL scores. The findings suggest Schroth exercises are more effective for structural corrections, while Lyon exercises are better for enhancing QoL in adolescents with idiopathic scoliosis.
