Dodgy ankles need to do this
The most important thing to teach your ankle after a lateral ankle injury is pronation. In other words to teach the foot to flatten.
If you injure the outside of your ankle the heel bone is stuck in a high arched position. If you don’t get the ankle to pronate then the foot is stuck in a position where you have injured your ankle
You need to get your heel back to a good POSITION before you start doing rehab
Please don’t do balance exercises with your eyes closed just fix the position
In the video below is a simple pronation fix for the ankle.
