Synergistic Effects of Schroth Method with and Without Core Stabilization Exercises in Idiopathic Scoliosis
Main Article Content
Abstract
Background: Idiopathic scoliosis is a three-dimensional spinal deformity that may affect spinal alignment, trunk endurance, chest mobility, body image, and health-related quality of life. The Schroth Method is a scoliosis-specific conservative intervention based on postural correction, spinal elongation, de-rotation, and rotational angular breathing, while core stabilization exercises aim to improve trunk control and spinal support. Objective: To compare the effects of the Schroth Method with and without core stabilization exercises on Cobb angle, lumbar extensor endurance, chest mobility, and quality of life in patients with idiopathic scoliosis. Methods: This assessor-blinded randomized controlled trial included 72 participants with idiopathic scoliosis, allocated equally into Group A and Group B. Group A received the Schroth Method combined with core stabilization exercises, while Group B received the Schroth Method alone. Treatment was provided for 10 weeks, with three supervised sessions per week. Outcomes were assessed at baseline, the 5th week, and the 10th week using Cobb angle, Sorensen test, chest mobility measurement, and SRS-22r domains. Data were analyzed using parametric repeated-measures approaches. Results: Both groups demonstrated significant improvement over time. Cobb angle decreased substantially in Group A and Group B. Group A showed greater improvement in Sorensen test scores, chest mobility, and SRS-22r function, pain, self-image, and mental health domains. At the 10th week, between-group differences favored Group A for Sorensen test and chest mobility. Conclusion: Adding core stabilization exercises to the Schroth Method may enhance functional endurance, chest mobility, and scoliosis-specific quality-of-life outcomes in idiopathic scoliosis rehabilitation. Verification of the inconsistent 10-week Cobb angle value is required before making a definitive claim regarding radiographic superiority.
