Re the comments on swimming .... glad the problem was solved. What my husband andI are doing it what they call "Deep Water Running" . With a therapist and a chest band to hold us up in the water, there are many exercises that can be done. Especi9ally for Ted, he can "walk" in the water without fear of "falling". We hope to sept out on our own soon at a hotel where we can go at our convenience for a membership fee. Our local Y is not really accessible with walker. Also you must go at the specified time which doesn't always work out. Ted's balance is much better after these sessions and it is supposed to help my arthritis.
