I read references to the UPDRS in medical literature and wanted to see if I could use it. I found it on the We Move site. "Since its introduction in 1987, the UPDRS has been used extensively by researchers and clinicians around the world". It can be obtained from We Move, 204 W. 84th St., New York, N.Y. 10024 or ordered from their web site: www.wemove.org/emove/ or it can be down loaded (free) from: www.wemove.org/par_df.html Al Isberg
