It is very important for people with Parkinson's to get exercise and physical therapy as part of an exercise regime helps a lot. I went for physical therapy for my shoulders and I was surprised at how much it helped. Now I must keep doing the exercises every day. If do not do them, I have trouble reaching into high cupboards in my kitchen and I also have trouble driving more than a short distance because my arms hurt when I hold them up on the steering wheel.

Parkinson's makes our bodies stiff. Exercise and physical therapy can help slow the progression of the stiffness.

The book Parkinson's Disease and the Art of Moving by John Argue will help you to help your father.
