Hello Cindy and welcome to the Parkinson's discussion on Mayo Clinic Connect. If your husband hasn't been referred for physical therapy, I would highly recommend him seeking out a physical therapist who is trained in the Big and Loud program. Big and Loud is a specific form of physical therapy for people with Parkinson's.

Here is a link to some information on this program,

If you or your husband would like to learn more about PD, I recommend that you look at The Davis Phinney Foundation website. https://davisphinneyfoundation.org/. You can learn much about PD and treatments through their videos with respected physicians in the field of PD research.

Often, with Parkinson's, a person's movements become very stiff. For example, a PD patient might shuffle rather than take regular steps when they walk. Also, they might not swing their arms when they walk, but walk in a stiff motion. The purpose of these exercises is to increase the movement.

The "loud" part of Big and Loud refers to strengthening the voice. With PD the voice will often become very soft. The voice therapy is usually conducted by a speech therapist. I have personally been involved in both the physical and voice training and it has been very helpful

Does this describe your husband's movements and/or voice? Has his neurologist referred him for physical and/or voice therapy?
