Reliability and Consistency Analysis of Multiple Instruments for Scoliosis Screening in Adolescent Males: A Comparative Study of Instrument Accuracy.

Abstract

The cause of adolescent idiopathic scoliosis (AIS) remains unknown, largely relies on Angle of Trunk Rotation (ATR) measurements via the validated Bunnell Scoliometer™. While low-cost, non-standard plastic inclinometers are increasingly utilized, their diagnostic accuracy remains uncertain. This lack of standardization may lead to inconsistent results and patient misclassification, necessitating a systematic comparison of these devices against a reference standard. This study evaluates the relia
