Brace wearing time is the strongest predictor of final results: A regression model in 1457 high risk consecutive adolescents with idiopathic scoliosis

Introduction/Background Current GUIDELINES propose PCA, but there are no large studies to check final results, and predict which patients will respond better. A personalised conservative approach (PCA) to adolescents with idiopathic scoliosis (AIS) is based on different treatment protocols according to risk groups (11–20, 21–30, 31–40, 41–45). The aim of the present research is to develop a model to predict end results of a PCA in adolescents with idiopathic scoliosis (AIS). Material and method Design: retrospective observational study nested into a prospective database. Inclusion criteria: AIS, 11–45°, Risser 0–2, age 10–16, first consultation, no previous bracing, at end of observation (Risser 3, medical prescription). Treatments followed a personalised conservative approach (PCA) following the step-by-step theory (Negrini, 2018): intensity increases with estimated risk factors. Outcomes: end Cobb angle  Results In total, 1457 patients, 82.6% females, age 12.11 ± 1.05. End  Conclusion Time of brace wearing is the strongest predictor of final results whether a
