Brief Summary

This observational study aims to examine the relationship between trunk postural changes measured using a mobile application (Biotonix Posture Assistant) and spinal curvature assessed by radiographic Cobb angle in adolescent females with idiopathic scoliosis. Thirty girls aged 14 to 17 years with moderate scoliosis will undergo a single posture assessment using the mobile application and a standard spinal X-ray. The study seeks to determine whether mobile-based postural measurements can reliably reflect radiological findings, offering a non-invasive and radiation-free option for screening and monitoring spinal posture in adolescents with scoliosis.

Study Arms (1)

Adolescent Idiopathic Scoliosis Group

This group includes female adolescents aged 14 to 17 years diagnosed with moderate adolescent idiopathic scoliosis (Cobb angle 40°-60°). Participants undergo a single assessment of trunk posture using a mobile application (Biotonix Posture Assistant) and standard posteroanterior spinal radiography as part of routine clinical evaluation. No therapeutic or experimental intervention is applied in this study
