Functional rehabilitation has a high probability of success
in functional ankle instability; however, the likelihood of
success is decreased with mechanical instability, peroneal
weakness, or proprioceptive deficits. Six weeks of aggressive
physical therapy is recommended. Orthotics can be useful
during the rehabilitation process, which can include a lateral
heel wedge or a heel lift. Taping has been used with variable
success but does not provide much support after 1 hour of
exercise. Bracing may also provide additional support for
the chronically unstable ankle.
