Yes, walking and moving in water is great, @mzpattilyn, I do that as well. There are specific PT programs for PD, one of them is called LSVT Big. Almost all PT centers have at least one person trained in "Big." It is very helpful. Here is some information regarding it,

Consistent movement is important for all PD patients. If I go a few days without some type of exercise, my balance, gait and range of motion decline. Give it a try!

I would like to hear from you again. Will you post if you try some PT or other exercises?

Hi Teresa my last back surgery was done last year, and nothing helps my pain at all. I still have the same pain now that I had before I had the lumbar L5-S1 disk fused, but the pain meds or physical thairpy doesn't even help the extreme pain go away.
