This randomized controlled trial assessed a six-week augmented reality (AR) movement and cognitive exercise program in 40 community-dwelling adults aged 65 years or older. Participants were assigned to AR exercise or usual daily activities. The AR group improved on the Timed Up and Go (p < .01), One-Minute Sit-to-Stand Test (p < .05), maximal inspiratory pressure (p < .01), and maximal expiratory pressure (p < .01). No significant changes were found in cognitive function or several other measured outcomes. The findings suggest potential benefits for mobility and respiratory muscle function, but do not establish broader cognitive or physical effects.
Key findings
- The AR group improved on the Timed Up and Go (p < .01) and One-Minute Sit-to-Stand Test (p < .05).
- Maximal inspiratory and expiratory pressures improved in the AR group (both p < .01).
- No significant changes occurred in cognitive function, Five Times Sit-to-Stand, or pulmonary capacity in the AR group.
- The control group improved in maximal expiratory pressure and Five Times Sit-to-Stand (both p < .01), while leg muscle mass decreased (p < .05).
Why it matters
Mobility and lower-limb function are relevant to maintaining independence in older adults. This trial suggests that an engaging AR-based exercise program may improve selected mobility and respiratory muscle measures, while showing no significant cognitive benefit. The mixed findings across outcomes underscore the importance of evaluating specific functional measures rather than assuming broad improvements from a single exercise approach.
What to keep in mind
The trial included 40 participants and lasted six weeks. The control group received no AR training and had no restrictions on other physical activity, which may complicate comparisons.
