Both Marling McReynolds and Gale Gross have asked: " . . . why do PWP have balance problems . . . how to avoid them...?" Hi Marling and Gale - The Parkinson's Disease Update, issue#73, 1997, contains a comprehensive, 3 page explanation of imbalance problems and how to avoid or mitigate them. It was written by Dr. Terry D. Fife, M.D., Ass't Professor of Clinical Neurology, University of Arizona College of Medicine. It covers "Causes," "Ways to avoid falls," "Balance exercises," and "Precautions." I can mail a photocopy to each of you if you wish. Stephan 52/6
