ESTUDO DE ACURÁCIA DIAGNÓSTICA ENTRE BACKSCNR® VERSUS RAIO-X NA TRIAGEM DE ESCOLIOSE IDIOPÁTICA EM JOVENS DE 10 A 17 ANOS PRATICANTES DE ATIVIDADE FÍSICA REGULAR

Abstract

Scoliosis is defined as a three-dimensional misalignment of the spine characterized by the appearance of a lateral curvature in the coronal plane, usually associated with the flattening of the curves in the sagittal plane and vertebral rotation along its longitudinal axis, with the latter alteration being considered fundamental to the mechanism of deformity development. Currently, the gold standard for scoliosis diagnosis is the Cobb angle measured by X-ray; however, the use of ionizing radiation precludes its application in large-scale screening campaigns. Previous studies have reported good accuracy of surface topography systems, such as BackSCNR®, for early detection of scoliosis, yet there remains a lack of robust comparative studies between these systems and panoramic X-ray, the gold standard for scoliosis diagnosis. Primary Objective: To compare the accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the BackSCNR® methods (screening, AVT-3D, and ART-3D modes) and trunk rotation angle (ART-ESC) in relation to the radiographic gold standard (Cobb angle) for the diagnosis of adolescent idiopathic scoliosis (AIS). Secondary Objectives: To determine the prevalence of AIS in a sample of youths engaged in regular physical activity (>3 hours/week) and those with lower-intensity regular physical activity (
