I received this e-mail from Patricia Halstead <[log in to unmask]>, who gave me permission to post in on the list. Possibly someone on the list can help her - I don't feel competent to answer her. I'm also asking her to join the list so that she can easily see the replies. You can do this, Patty, by following instructions on http://members.fortunecity.com/panforum/alistsrv.html. This site will also lead you to other articles on the List. Art Here's her letter: My Father, Edward Mihoces, Sr. (retired Police Chief in PA) had a knee replacement about 4 years ago. He felt fine and managed well after his surgery. After his second knee replacement surgery, he was diagnosed with Parkinson's. Is it possible that because his knee was prosthetic that his brain could not communicate with that area and there was a malfunction in movement? It seemed to happen after his knee replacement. He falls down when he thinks he is capable of moving. Is there a connection? I live a long way off from PA, on the Russian River in N. Calif. I am so pre-occupied by his situation and feel that there's more to it that what he's told. Can you help me? --- Patricia Halstead --- <mailto:[log in to unmask]>[log in to unmask] ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
