RecruitingBehavioural interventionPreserving Ability Through Virtual Exercise (PAVE)Each day in the hospital leads to functional decline and loss of muscle mass, which older adults can find difficult or impossible to restore in the post-acute period. The overall objective of this proposed project is to explore the feasibility and preliminary efficacy of a virtual reality physical activity intervention at helping older adults engage in physical activity and maintain physical function and mental health during their hospital stay. As virtual reality technology becomes more affordable and ubiquitously available across the world, this study will demonstrate how this technology could be leveraged to maintain the function of older adults in the hospital.
