Hi Srini, My dad has the same problem, instead of shivering he has slow movements and faces problems with the mobility. Even he takes Syndopa Plus (half tab) twice a day. I was about to start Physiotherapy for him as well but after reading your blog I started thinking about. May be I will have to go to my Dr back and consult him for any other and proper options. So far I could not find any cure or treatment on the Internet and not from my Dr. either. May be small exercise could help!!!!! My dad got a mild stroke 10 years ago which has become a major cause of Parkinson's. Diabetics and Hypertension are the other major reasons!!!!! Thanks Kunal
