Thank you for being part of the Light for PD clinical trial.

Your participation helped make possible one of the largest fully remote clinical studies of an investigational device in Parkinson’s disease. Because of volunteers like you, researchers can continue exploring new approaches to addressing the challenges faced by people living with Parkinson’s.
