While in use, the brace brings the spine closer to the midline or even further by applying both lateral and rotational pressure on the patient's body.
The brace applies pressure at three points on the body while the patient is in the

The supine position ( or ) means lying horizontally with the face and torso facing up, as opposed to the prone position, which is face down. When used in surgical procedures, it grants access to the peritoneal, thoracic and pericardial regions; ...

curvature of the spine.
The brace is worn for at least eight hours at night and during sleep as it significantly limits mobility while in use.
The brace is indicated for adolescent patients with curves of less 35°.
A recent study indicates that the brace is also effective for curvatures up to 45°.
When used on appropriate patients, Providence brace has been shown to have a comparable efficacy as traditional scoliosis orthoses (such as the
Boston brace
The Boston brace, a type of thoraco-lumbo-sacral-orthosis (TLSO), is a back brace used primarily for the treatment of idiopathic scoliosis in children. It was developed in 1972 by M.E "Bill" Miller and John Hall at the Boston Children's Hospital i ...
) that require full-time use.
Studies report that 50% to 75% of patients show further curve progression of only 5° or less, including when examined two years after stopping use of the brace. A 2019 study also reported that, if an in-brace correction of more than 70% is achieved, the Providence brace was successful in preventing curve progression in 89% of compliant patients.
History
In 1992, Charles d'Amato and Barry McCoy created a board on which scoliosis patients can be positioned in a way that corrected the curvature of their spine.
