It is intended for weakness or correction of abnormality. A brace can be used to support weak limbs or to place the limb with an AFO, contracted muscles in a more normal position. In addition to these, musculoskeletal AFOs are used to control ankle sprains caused by various neurological disorders. This helps to reduce the risk of toe infection. This brace has provided freedom of movement in extension at different stages of walking, but limits flexion at 90 degrees.
