Dorothy,
Most YMCA's have an arthritis class for people who need water to exercise. Even in our small town they do. I was going to the YMCA on a regular basis for the hydrobics classes. (til bones started breaking) They have instructors who teach you how to exercise in water. It's wonderful for range of motion. You don't have to be able to swim, the exercises are done in the shallow part of the water. Only water up to your chest. I can't swim anymore and they were easy to do. It helped a lot. Check around and see if you can find some of these classes close to you. I'm going back as soon as the doctor says I can. It's fun too and I've met a lot of people, some who email me.
