I did the alphabet (drawing the letters of the alphabet with affected foot) for flexibility. We also did marching in place, standing on one leg, sideways walking, hopping, and squats. I know we did other stuff but it was a while ago. I was able to handle most things well in the water and we did the water therapy until I could essentially handle those same exercises on land. The one thing that caught me off guard with how painful it was in the water was using a kick board and kicking in the water. that motion and the pressure it put on my rsd affected ankle was agony...I almost passed out the pain was so bad. Needless to say...we never attempted THAT exercise again. just be cautious, try everything and ease into stuff. Admit when something is too much and try something else. start with small repetitions and work your way up with each exercise.
