Another comment to keep in mind re: treadmill training....... Some of us have gait problems, and using the treadmill only exaserbates PD symptoms. Before urging/pushing your PWP on to the treadmill be sure to evaluate the mobility of the PWP or ask your local physical therapists or physician for his/her opinion. We are not all moving the same. The treadmill is probably helpful for patients without some gait irregularities...anything to give exercise and promote better cardiovascular conditioning. However, those who freeze, drag a foot, have foot drop etc. may not respond to treadmill therapy. Rita Weeks
