During the mid 19th century, French neurologist, Jean-Martin Charcot discovered patients with Parkinson’s disease felt better after a carriage ride. He theorized the “shaking” and vibrations from the ride somehow eased the symptoms. To test the hypothesis, Charcot designed a special “shaking” chair for his patients. Reportedly, those who used the chair had less pain and stiffness and improved sleep quality.

Now, some modern-day physicians are picking up on the idea for current Parkinson’s patients. Researchers at Rush University Medical Center in Chicago are testing the use of a sophisticated vibration chair. The chair cushion contains speakers that are connected to an amplifier. When the patient sits in the chair, the music is turned on and the acoustics from the speakers generate strong vibrations.
