While studies with high intensity exercise continue to gain attention as preventing deterioration in the still mobile and active,the rest of us are left in limbo with no programmes that offer real help. QUOTE]

I think that every study I've read on the benefits of exercise and activity for helping PwP has been positive, no matter what the form. It may be true that we don't know yet which regime is best. However, I believes it's pretty conclusive that any regime is better than nothing. So, if you can't do a high intensity exercise, you can continue your walking. There was a study published last week (I will look for the link) that showed distance walking as the best regime, even more so that fast treadmill walking. There are also plenty of studies supporting Tai Chi, Quigong, dancing, chair dancing, or chair stretching exercises. My point is, unless you are totally immobile, there is a routine for you that will work and provide some benefit to PD symptoms.
