Thanks for your posting on excercise: my experiences: my dr. recommended a regimented excercise program and gave me a perscription. I learned of a physical therapist who knew pd and ms and he called my insurance co for approval. THEY ACCEPTED and I went 3times a week for 3weeks. My pd settled in my legs so we did all types of stretching and rotating sessions. Also he showed me balance excercises on a large rubber ball. Everyone who knows me saw an immediate difference. VERY POSITIVE We left on a two week holiday and because I had to attend to college preparations for my son I neglected to go back...its been three weeks now. Everyone who knows me saw an immediate difference THIS TIME IS WAS NEGATIVE Ive made arrangements to begin again in ernest this coming week. If anyone has any doubts about p.t. your wrong.....DO IT !!!!! IT MAKES A TREMENDOUS DIFFERENCE PHYSICALLY AND MENTALLY. JOYCE
