Had my 2nd physio session today, lady said give it another few weeks before getting back on the water, but she gave me a few exercises to help strengthen the ankle which can help anyone who thinks their ankles are weak.
1. Stand upright arms forward, now stand on the balls of your feet and hold. Then back down so your heals remain off the ground, hold, then back up on your toes. Should repeat this a few times a day.
2. When brushing your teeth try doing it on one leg, as you progress go up on your toes.
3. Stand on one leg and throw a ball against a wall so it comes back so you can catch it.
4. Use an exercise band, like a big elastic band, hold one end and place the other end around your foot. Pull on the band and hold, now with a straight leg (sitting down) flex your foot away as much as you can and hold for 5 seconds, still pulling on the band slowly let your foot flex pointing up towards you stretching you achilles slowly, I was told to do this 15 times a day slowly building up.
All these moves are meant to build muscle up in your ankles, stop sprains etc. someone posted an ankle support, a McDavid, I showed her and she said it would be good as an additional support and should be ok for water use, I will do my exercises, wait a few weeks and use a support, hopefully that way I will have a better chance of full recovery. Hope this helps someone, please seek professional advice before doing the above
