Impact of Schroth Treatment and 3D Schroth Brace on Spinal Alignment, Posture, and Respiratory Function in Adolescent Idiopathic Scoliosis: A Case Study.

Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional spinal deformity that often requires a multimodal conservative approach during the growth period. This case study presents the outcomes of one year of combined Schroth physiotherapeutic scoliosis-specific exercise (PSSE) and three-dimensional (3D) Schroth bracing in an 11-year-old girl presenting with a thoracic Cobb angle of 60° and a Risser sign of 0. Clinical, radiographic, topographic, and spirometric parameters were monitored at baseline and after 12 months. The thoracic Cobb angle decreased from 60° to 38°, the angle of trunk rotation (ATR) from 23° to 19°, and coronal balance from 25 mm to 11 mm. Spirometric values showed consistent improvement across all measured indices. These findings indicate that intensive, supervised Schroth therapy combined with customized 3D bracing can achieve clinically meaningful curve reduction and functional improvement in skeletally immature patients with severe AIS.
