This study focuses on adolescents with idiopathic scoliosis, employing 3D imaging technology with depth cameras to measure back height difference (BHD) and angle of trunk rotation (ATR) before and after conventional treatments such as massage, exercise therapy, and bracing. Statistical analyses are conducted to verify the correlation between BHD and ATR and to assess the sensitivity of BHD in evaluating short-term treatment effectiveness.

Inclusion Criteria:

(1) Adolescents aged 10-18 years, diagnosed with adolescent idiopathic scoliosis (AIS) with a Cobb angle ≥10°; (2) No history of spinal surgery or other corrective treatments; (3) Able to undergo short-term inpatient treatment (5 days) and comply with study procedures.

Exclusion Criteria:

(1) Patients with congenital, neuromuscular, or other secondary scoliosis; (2) Presence of major comorbidities affecting spinal structure or muscle tone (e.g., spinal cord injury, muscular dystrophy); (3) Patients unable to complete standardized assessment procedures.

This study focuses on adolescents aged 10-18 diagnosed with adolescent idiopathic scoliosis, defined by a Cobb angle of ≥10°.
