Virtual Reality and Field Training to Enhance Community Walking After Stroke

While stroke survivors discharged from rehabilitation present with some recovery in mobility, their ability to ambulate in the community remains limited. The investigators propose to test a novel, low-cost, intensive and individually tailored intervention that combines virtual reality (VR) and field training to enhance community ambulation and participation in stroke survivors discharged from rehabilitation. The aims are to: (1) Assess feasibility, acceptability, safety and adherence of the intervention in stroke survivors; and (2) Examine the extent to which post-intervention changes in functional walking and participation to community walking vary according to walking, cognitive and visual-perceptual abilities. The investigators will use a virtual environment prototype simulating a shopping mall and surrounding streets, in which participants will interact using VR goggles and game controllers. Scenarios of increasing levels of complexity will be introduced. This intervention study involves a single group, multiple pre- multiple post- study design where chronic stroke participants will engage in a 4-week training program. The program will include VR training sessions performed in the clinical setting (3/week) and practice of community ambulation skills while supervised by family/caregivers (2/week). Participants will be assessed on measures of functional walking, balance \& mobility and participation to community walking. Adherence, safety and acceptability will be documented. This study will generate foundation knowledge on the response to the intervention based on individual capacities.
