Because of the force often associated, it is very common for there to be double ligament injuries (usually involving the main two lateral ligaments: anterior talofibular ligament and calcaneofibular ligament). Double ligament injuries do take longer to heal depending on the grade of the tear.
Essential to get the rehab correct to ensure further ankle ligament tears are minimised as much as possible.
Proprioception: wobble board, s/l balance/squat control, incorporating hand/eye coordination (particularly for ball sports) i.e. standing on one leg and throwing ball against wall (also specific to gymnastics regaining single leg control)
