Adolescent Idiopathic Scoliosis (AIS) is a common spinal deformity affecting adolescent health, and early diagnosis and accurate assessment are crucial for preventing disease progression. Traditional assessment indicators, such as the trunk rotation angle (ATR) and Cobb angle, rely on clinical examinations and X-ray imaging, which have certain limitations, including radiation exposure and insufficient sensitivity. The Back Height Difference (BHD), as a quantitative measure of the back surface morphology, may reflect the degree of trunk deformity caused by scoliosis.
The use of the Kinect v2 depth camera to capture three-dimensional point cloud data of the back provides a high-precision, radiation-free assessment method.

This study focuses on adolescents aged 10-18 diagnosed with adolescent idiopathic scoliosis, defined by a Cobb angle of ≥10°.
Cohort
Cross-sectional
no intervention
Diagnostic testThis is a diagnostic test with no intervention.
Back height difference
Using depth cameras to acquire back data, point cloud processing algorithms analyze the information. The height difference between the highest point on the convex side and the corresponding point on the concave side is measured, with three repetitions taken to calculate the average value.
Angle of trunk rotation
A scoliometer is used to measure the patient's angle of trunk rotation (ATR). Measurements are repeated three times, and the average value is taken.
