Hello @jaybee51

From your post, it looks like you are having difficulty finding some group exercises for your Parkinson's diagnosis. Here are some ideas that might help.

First, contact your neurologist's office and ask them if they know of any places where you might find a PD exercise program. In my area, the local YMCA have programs.

Also, there are physical therapists that help PD patients. The program is called Big and Loud. You might consider asking your doctor for a referral to one of these physical therapists. Here is the website where this program is explained. https://www.lsvtglobal.com/LSVTBIG

There are a lot of YouTube videos (free for your use) for people with PD. Here are some links that you can review. Many of these exercises chair exercises.
