Influence of body mass index on the reliability and validity of ultrasound assessments in adolescent idiopathic scoliosis: An original research.

ABSTRACT:

Objectives

Clinical ultrasound provides a non-invasive method to assess spinal curvature in adolescent idiopathic scoliosis (AIS). However, the reliability and validity of ultrasound assessment may be affected by body mass index (BMI). This study investigated the impact of BMI on the reliability and validity of ultrasound assessments in AIS.

Design

165 participants with suspected AIS were recruited for both ultrasound and radiographic assessments. Lateral spinal curvature was measured on ultrasound imaging using the spinous process method and on X-ray using the Cobb method. The same operator performed two ultrasound scans for each participant, and two independent raters measured the images (Rater 1: 1st and 2nd scans; Rater 2: 1st scan only). Intra-operator and inter-rater r
