Abstract: BACKGROUND: Three-dimensional motion capture technology has developed a variety of models for different diseases through its computer-aided characteristics. There are no good models available for clinically instructive assessment of adolescent idiopathic scoliosis.  
OBJECTIVE: To establish the thoracic volume and abdominal volume models of adolescent idiopathic scoliosis based on 3D motion capture system.
METHODS: Fourteen patients with adolescent idiopathic scoliosis, aged 10-18 years, were selected from Shanghai Yangzhi Rehabilitation Hospital (Shanghai Sunshine Rehabilitation Center), Shanghai No. 6 People’s Hospital Affiliated to Shanghai Jiao Tong University, and Shanghai Children’s Medical Center Affiliated to Shanghai Jiao Tong University from July 2020 to July 2021, including 2 males and 12 females. Chest circumference and Cobb’s angle of all patients were measured. The models of thoracic volume and abdominal volume were established by three-dimensional motion capture system. The correlation of thoracic volume and abdominal volume with age, chest circumference and Cobb’s angle was analyzed.  
RESULTS AND CONCLUSION: The thoracic and abdominal volumes at maximum inhalation and maximum exhalation were positively correlated with chest circumference, but not correlated with Cobb’s angle. The models of thoracic volume and abdominal volume of adolescent idiopathic scoliosis were established based on three-dimensional motion capture system. This method is proven to be a harmless, accurate and quantitative detection of thoracic and abdominal volumes for patients with Cobb’s angle ranging from 10° to 45°.
Key words: adolescent idiopathic scoliosis, 3D motion capture, thoracic volume, abdominal volume
