I am 51 and have had PD for 4 years. My first symptom, and still my most troublesome, is dystonia in my right foot. I'm not sure what exercises might help, but one thing that helped me for a couple of years was an orthotic device which fit under the liner of my shoes. It is leather and has a hump in the middle which forces my toes to straighten out. It's not very comfortable, but is better than the cramps in my foot. Increasing my Sinemet dosage and taking it more often throughout the day also was a big help in avoiding this problem. Janice Glidden 51/4
