Conditions

Adolescent Idiopathic Scoliosis

Brief summary

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.

Design outcomes

Primary

Measure	Time frame	Description
Back height difference	Day 1 of Admission and Day 5 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

Measure	Time frame	Description
Angle of trunk rotation	Day 1 of Admission and Day 5 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.
