My father, 84, pd for 20+ years has had good luck with water exercise, very good. His energy level and awareness has really increased. He goes to a pool three times a week and exercises two days at home. He now gets in and out of a car by himself. We are having trouble keeping him from doing too much (walking around at night alone with his walker). We also took him off of Welbrutin and increased his Sinimet to one-half 25/250 every two hours during waking hours.
