8-Week Non-Immersive Virtual Reality Exercise Program: An Engaging Fitness Solution for Older Adults
Exercise is vital for maintaining health and independence in older adults. Yet, many seniors face barriers to regular physical activity. A recent study explored the effectiveness of a non-immersive virtual reality exercise program for older adults, providing insights into its benefits and potential as a fitness solution.
The Study Setup
Researchers at Bruyère Health Research Institute and Centre for Innovation and Research in Aging in Canada conducted a randomized controlled trial involving 47 participants. Two groups were formed: one living independently at home and the other in long-term care facilities. Participants were randomized to use a custom non-immersive virtual reality (NIVR) program or their regular daily activities for 8 weeks.
The NIVR program included customized gamified exercises focusing on balance, stepping, strength training, and aerobic conditioning. Participants exercised 3-5 times a week, with each session lasting 20-30 minutes.

Key Study Outcomes
Impact on Balance and Physical Function
The study assessed several measures of physical function, including balance, strength, and mobility. While no statistically significant benefits were observed overall, the long-term care group showed a clinically significant improvement in functional walking.
Fall Prevention and Safety
No falls occurred during NIVR sessions, indicating the safety of the program. Among participants in the long-term care group, 4 experienced falls outside of NIVR. In the home-based group, no falls, emergency room visits, hospitalizations, or long-term care admissions were reported.
Exercise Adherence and Program Enjoyment
Both groups engaged moderately with the exercise program. Facility-based participants completed an average of 14.1 sessions (20.1 minutes each), while home-based participants averaged 17.2 sessions (22.6 minutes each). Participants enjoyed the NIVR program, finding it motivating and challenging. Many expressed interest in continuing the program beyond the study duration.
Discussion and Implications
Program Effectiveness
The observed improvements, particularly among long-term care residents, suggest that non-immersive virtual reality can enhance physical function. However, the modest impact may be due to the program’s relatively short duration and intensity. Longer interventions could potentially yield more pronounced benefits.
Feasibility and Acceptance
The study confirms that NIVR is feasible, safe, and enjoyable for older adults. It aligns well with the preferences of seniors who find traditional exercise programs unappealing. Technological barriers, such as limited access to suitable hardware and adequate study partner support, should be addressed to maximize the program’s reach.
Limitations
The study faced several limitations, including a small sample size and challenges during the COVID-19 pandemic affecting participant recruitment and engagement. Future research should explore larger and more diverse populations to validate the findings.
Conclusion
In conclusion, non-immersive virtual reality exercise holds promise as a versatile and engaging fitness solution for older adults. By addressing physical barriers and enhancing motivation, it offers a valuable addition to existing exercise programs. As technology continues to evolve, these innovative approaches could significantly improve the health and well-being of seniors.
