Disclaimer:
I am not a physiotherapist. However, in the 5th year of my degree, my grade in Kinesiology in Injury Management was a 'B'. Use your head, have all injuries checked by a doctor or physio. Ignoring an acute(sudden) injury can lead to it becoming a chronic(long term) injury that's a bugger to treat.
Ankle Injury Rehabilitation Program
The following exercises may be used to rehab ankle ligament injuries. It would also be of use to strengthen the joint following an period of forced immobilisation. The program may be advanced according to the severity of the injury. When weight bearing is allowed, advance to steps 6-15 as symptoms permit, and with doctor/physio’s permission.
