Visual Perturbation Training to Reduce Fall Risk in People with Parkinson's Disease

Falls during walking are common in people with Parkinson's Disease (PD). Fall risk can be attributed in part to the loss of automaticity in walking and an increased reliance on sensory cues, such as the input from the balance organ. In this project the investigators want to assess the effectiveness of rehabilitation training aiming to improve this vestibular input. The effects of a visual perturbation training in a virtual reality environment will be compared to conventional treadmill training.
