The main goal of this study is to determine if an ideal set of force parameters, magnitude, location, and direction, can be established to use with the Providence brace to improve the successful outcomes for bracing treatment of adolescent idiopathic scoliosis (AIS). A literature review shows the significance of corrective forces in bracing success, however, there is no consensus on optimal force application regarding magnitude, location, and direction of the forces used. The study will evaluate 73 AIS patients over the course of their bracing treatment, using patient records, x-rays, and Pliance PMS sensors for precise force measurement. Procedures will include initial evaluation, brace fitting, follow-ups every 4-6 months, and x-rays immediately and two years post-bracing. Data analysis will compare force application with spinal correction outcomes to identify which forces result in the greatest effective bracing forces. The study aims to determine if Providence brace design parameters can be standardized to improve treatment success. These findings will contribute to evidence-based AIS treatment, potentially leading to improved brace designs and higher success rates, thus laying groundwork for future AIS research and innovation.
