An orthosis is a mechanical aid, such as a brace, to support, restrict or assist movement of a weak or injured part of the body.   It also can reduce weight bearing forces.  The weakness may be due to conditions such as abnormal tone and neurological dysfunction.  They can aid rehabilitation from fractures after the removal of a cast. Orthoses for the feet are generally referred to as orthotics.
