Description. Parkinson’s disease is characterized by its progressive movement problems, but deficits in sensory function and processing can exacerbate these problems and have a negative impact on balance and function. By using movements of an immersive visual scene and electrical stimulation to the vestibular system, we can provide sensory stimulation that challenges a person’s sense of balance. We can then track and quantify the balance response through infrared motion-capture video, pressure on a force plate, and electromyographic (EMG) activity. To understand these deficits in the larger context of function and rehabilitation, we look for relationships between balance responses and self-reported balance confidence and quality of life.
