Is this trial a fit for you?

Likely a good fit

Ideal candidates are skeletally immature adolescents aged 9-17 with idiopathic scoliosis and a Cobb angle between 25-40 degrees.

Probably not a fit

Patients with non-idiopathic scoliosis or those who have previously undergone spine surgery will not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the effectiveness of a newly developed 3D designed Boston brace compared to the standard Boston brace for treating idiopathic scoliosis in skeletally immature adolescents. Participants aged 9-17 with a Cobb angle of 25-40 degrees will be randomly assigned to receive either type of brace. The study will monitor compliance using thermal sensors and assess outcomes such as curve severity, quality of life, and surgical rates through clinical and radiological follow-ups. The goal is to improve brace comfort and increase wearing time, ultimately leading to better treatment outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved brace comfort and compliance, resulting in better management of idiopathic scoliosis in adolescents.

How similar studies have gone: Previous studies have shown that innovative brace designs can improve compliance and outcomes, suggesting potential success for this novel approach.
