Regarding piano playing, etc. without symptoms, there is some good research on the fact that music takes a separate path in the brain and thus, when one yields to it, can bring about activity which is not usually possible when cognitively trying. Any kind of music which "moves" an individual can have this effect. One of my favorite authors is the neurologist, Oliver Sacks. In his interesting and entertaining book, A LEG TO STAND ON, he describes his own dramatic personal experience with this when he was healing from a broken leg which severely damaged nerves. My own experience confirms this. I was particularly ill due to some other medical problems in addition to the Parkinsons, totally drained of stamina, and had been so for months. On the radio came some spirited Gilbert & Sullivan. I'm an in-the-closet dancer (no peeking!). Anyway, on came the music, off the couch came me without thinking, and for the first time in months I was energized. I was so grateful I called the NPR station & donated $50! There truly is serious research on this. Techniques are being used now with stroke victims and those with various other challenges. So crank up your favorite music & let yourself go!
