Hi, a few days ago I landed a backflip very low and as a result injured my ankle as all my bodyweight fell on my fully dorsiflexed ankles. Now I wonder whether that is a hole in my ankle joint preparation. I do inversion and eversion preparation but putting weight on my (left uninjured) ankle when fully dorsiflexed seems to rub bone onto bone which gives me pain. Is there a safe way to strengthen my ankle in a fully dorsiflexed position so that it can take the impact of such a strain in the future? thx for your ideas
