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.

Detailed Description

Adolescent idiopathic scoliosis is a common spinal deformity that typically develops during the adolescent growth period and predominantly affects females. Accurate assessment of spinal curvature is essential for clinical decision-making and follow-up; however, repeated radiographic evaluation exposes patients to ionizing radiation. Therefore, non-invasive assessment tools are increasingly needed.

This observational cross-sectional study aims to investigate the relationship between trunk postural deviations measured using the Biotonix Posture Assistant mobile application and radiographic Cobb angle measurements in adolescent females diagnosed with idiopathic scoliosis. Thirty female participants aged 14 to 17 years with moderate scoliosis (Cobb angle between 40° and 60°) will be recruited.

Each participant will undergo a single postural assessment using the mobile application to measure trunk rotation and translation along the X and Y axes while standing in a standardized position. Standard posteroanterior spinal radiographs will be used to determine Cobb angles as part of routine clinical evaluation. No therapeutic intervention will be applied as part of this study.

Statistical analysis will include correlation and regression methods to explore the association between postural parameters obtained from the mobile application and radiographic findings. The results of this study are expected to support the clinical utility of mobile-based posture assessment as a complementary, non-radiographic tool for screening and monitoring spinal deformities in adolescents
