Brace treatment is the most effective non-surgical method for the treatment of Adolescent
idiopathic scoliosis (AIS). The goal of bracing is to stop the curve progression during the
high risk period of the adolescent growth spurt. A spinal brace is a hard plastic shell with
pressure pads installed inside the liner to provide mechanical support to the curvature of
the spine. It is a big commitment for adolescents to wear a brace because it is physically
restrictive, uncomfortable and draws unwanted attention. Therefore, it is very important to
make the brace treatment as effective as possible to get patient buy-in to compromise their
lifestyle by wearing a brace. Patients' belief in the treatment outcomes is also a factor to
attain their compliance.
This randomized clinical study will investigate if the effectiveness of brace treatment can
be maximized by combining ultrasound imaging assistance during brace design with the smart
brace to automatically maintain corrective brace pressures at the optimum level during the
whole treatment period.
