An orthosis (sometimes called an orthesis) is a device that is applied externally to a part of the
bodyto correct deformity, improve function, or relieve symptoms of a diseaseby supporting or assisting the neuro-musculoskeletal system. The word is derived from "ortho", meaning "straight".
Orthoses are sometimes called orthotics, though this is technically the medical field concerned with the application and manufacture of orthoses.
