As many of you may know I am involved in research exploring the relationship between vision and some of the motor problems of PD. The goal is to overcome some of these problems by building vision based therapeutic devices. It would be very useful to me if I could occasionally ask a few questions of the PD population who read this bb. If anyone feels this is an inappropriate use of this forum, please let me know. Question: If you have PD and exhibit dyskinesia while walking (i.e. you are medicated and "on" and your walk has a lot of irrational, extra movement) 1. Does walking more rapidly improve your walk? 2. Try walking with your head up and arms extended straight out in front of you at eye level with your hands hyperextended back in a position so you can see your finger nails. Focus on your eyes on your finger nails while walking, does this improve your walk? Answer form (copy, fill out and return) Question 1; yes: no: Question 2; yes; no: Comments: Thanks, Tom
