I had an operation in July '96. to control PD-like symptoms caused by normal pressure hydrocephalus. This can be confused with PD. I may or may not have PD as well. I still have some PD-like symptoms. For the first time since the operation, I tried to play tennis. I played 2-3 hrs. per day before the operation. The first shot I tried to run down, my brain said run but my legs couldn't keep up with my body. I did an awesome swan dive on an asphalt court; at least a 9.5 score. Results were knees and hands bloody, two wrenched shoulders, and a destroyed ego. Question: can I cope with this in tennis and other sports or do I just give them up? Barbara Smith, CG/Ken/69/16
