The Use of Home-Based Nonimmersive Virtual Reality to Encourage Physical and Cognitive Exercise in People With Mild Cognitive Impairment: A Feasibility Study.

Individuals with mild cognitive impairment are at risk of cognitive and physical decline. Virtual reality (VR) exercise may provide beneficial physical and cognitive exercise. The objectives of this study were to assess the feasibility and safety of home-based VR exercise and to provide pilot data for physical and cognitive efficacy. Eleven individuals with mild cognitive impairment (seven males/four females, average 78 years old, and average 3 years since diagnosis) performed a 30-min home-based VR exercise program 5 days a week for 6 weeks. The VR platform was successfully installed in participants' homes, and all participants were able to learn the VR program and progress. Participants completed 99% of the prescribed exercise. There were no major adverse events. Most participants enjoyed the VR program and reported physical benefits; fewer reported cognitive benefits. No physical or cognitive outcome measures showed change after 6 weeks. Home-based VR exercise is safe and feasible in individuals with mild cognitive impairment.
