An orthosis is an external orthopedic appliance or device that is designed and fitted to support, align, prevent or correct deformities, or to improve the function of movable parts of the body. In occupational therapy practice, orthoses are commonly fabricated for the upper extremity to support healing, prevent contractures, or enhance functional performance. Occupational therapists are trained in the design, fabrication, and fitting of custom orthotic devices.
