About

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.

Enrollment: 80 estimated patients

Sex: All

Ages: 10 to 18 years old

Volunteers: No Healthy Volunteers

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.

Trial design

80 participants in 1 patient group

Description:

BHD Measurement: Each participant undergoes two measurements by two different assessors, with a 5-minute interval between each measurement. The average value is taken. ATR Measurement: The trunk rotation angle (ATR) is measured using a Scoliometer. Two assessors each perform two measurements, with a 5-minute interval between each, and the average value is taken. Cobb Angle Measurement: Two experienced spinal specialists independently measure the Cobb angle, with each performing two measurements. The average value is taken. If their measurements differ by 5° or more, a third senior physician is required to perform a review.

Treatment:

Diagnostic Test: no intervention
