What happens then is the patient will develop a chronic ankle sprain syndrome. Just like those athletes that chronically dislocate their shoulder. Once damaged, if not properly taken care of, it will occur again and again. This is how stability and proprioception are very closely related. All we do is move heavy weight.
Balance is important in more ways than one.
If you can, try that with eyes closed. When you can't do the above, you need to improve your balance. This is where stability comes in again. Watch the muscles around your foot and ankle when you try and stand on one foot. You will see them twitching and contracting and relaxing all at different rates and time.
