Hi for me and of course everyone is different but I need a firm and stable ground. Sand would make my ankle/foot turn out which would cause a flare up. I can see though if there were not so many barriers how the ocean could be calming.
Rachel I am sorry about your daughters increased pain. Have you tried changing the form of PT she does? I guess I feel what mayhelp one person may not another. I know hat PT can increase pain but in the long run hopefully it helps but some pain is just too much to take. I have a friend for ex who like massage and for me that would increase my pain to a intolerable state. As for the pool at Cleveland Clinic we used those noodles and dumb bells for the pool. If I ever go back to the pool I am going to get those items and also try walking back and forth. Welcome to the board though I am sorry for your daughters pain
