Good Morning Joan-- Dr. Janet Chance is the Director of the Parkinson's Center of Excellence at Hoag (? spelling) Hospital in New Port Beach, CA. I would suggest you start your query with Mignone Trinery, Parkinson's Patient Service Coordinator, (949) 574-6338 at that location. Hopefully she will have some sound suggestions....if not, please advise so I may send further thoughts. Tonight I'm off to a local fund raiser, SHAKE, RATTLE AND ROLL 40's/50's Dance Party. It has been foreeeeever since I've danced, but am sure my toes will be tapping--can hardly wait! Enjoy that new upgrade. Talk soon. Sharon
