Margie, I have what dad has plus I hesitate at door frames. I dont "freeze" in the middle of the street. VERY INTERESTING that a twin D.B.S. didnt help....well so much for any help I thought that mite bring me.... damn!!!!! Things with PD work in funny ways. I am thankful beyond any words that my most physically painful toe and foot curling experience was cured by a taking a chance that an operation not intended to cure this actually did. Since my pallidotomy in February '96 I've been free of the curling but I still am almost 90% dependent for walking. Maybe the trials in Denmark on a new formula will eventually help me...until then Ill keep pushing and pushing... Good luck to dad and keep in touch Joyce
