3D Depth Camera-Based Assessment of Adolescent Idiopathic ScoliosisUsing a Depth Camera

Recruiting

• Conditions: Adolescent Idiopathic Scoliosis

• Registration Number: NCT06717568
• Lead Sponsor: The First Affiliated Hospital of Zhejiang Chinese Medical University

Brief Summary

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.

• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Back height difference	Day 1 of Admission	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.

Secondary Outcome Measures

Name	Time	Method
Angle of trunk rotation	Day 1 of Admission	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.
