The aim of this study was to investigate whether adolescent with idiopathic scoliosis receiving scoliosis specific exercise approach, such as SEAS exercises, in accordance with the bracing approach for moderate curves would have greater improvement in curve progression, trunk deformity, body symmetry and quality of life than adolescent receiving exercise therapy based on the general core stabilization approach with similar intensity. Thirty female patients with AIS aged 12 to16 years, who have moderate curves (20 to 45 degree) randomly divided into two groups. One group received CS exercise, while other received SEAS exercise for forty-min once weekly for four months. Both groups underwent full-time bracing (23 hours per day) intervention. Outcome was based on Cobb angle, angle of trunk rotation, body symmetry (Posterior Trunk Symmetry Index), cosmetic trunk deformity (Walter Reed Visual Assessment Scale) and quality of life (Scoliosis Research Society - 22 Questionnaire) measured at baseline and after intervention period. Results were analyzed using the paired sample t-test to compare repeated measurements and independent sample t-test to compare the groups.
