Introduction: Structural scoliosis is a twisting deformity in the curve of vertebral column to the lateral side with simultaneous rotation of the vertebrae, which occurs during the growing years from 10 years to the puberty. Aim of the study: Studies investigating balance problems specific to scoliotic patients showed that those patients reveal variable balance abnormalities. In this study we evaluated the difference in postural stability responses between female patients (students, office workers and shish weapon players) with structural scoliosis and normal subjects. Materials and Methods: Sixty subjects participated in this study. Thirty female patients with structural scoliosis with a mean age of 19.5 ( ± 3.26) years, with Cobb's angle ranged from 20º to 40° in the major curves, and thirty healthy female subjects with a mean age of 19.36 ( ± 2.41) years. Postural stability of both groups was evaluated by the Biodex Stability System. Results: There was no significant difference between both groups in dynamic balance test. Conclusion: As there was no significant difference between both groups in balance response, it is not recommended to add balance training as an extra physical therapy program for adolescent idiopathic scoliosis (AIS) female patients.
