An Exploratory Study on Virtual Reality Technology for Fall Prevention in Older Adults with Mild Cognitive Impairment

Area of Science:

• Gerontology
• Rehabilitation Science
• Cognitive Neuroscience

Background:

• Virtual Reality (VR) training is a potential intervention for reducing fall risks in older adults with mild cognitive impairment (MCI).
• Cognitive-motor interventions may enhance postural balance and cognition for safer walking in this population.

Purpose of the Study:

• To evaluate the effectiveness of VR training in mitigating fall risks among older adults diagnosed with MCI.
• To assess the impact of VR training on cognitive-motor performance, functional mobility, and psychological factors related to falls.

Main Methods:

• An experimental design utilizing a full-immersive VR Cave Automatic Virtual Environment (CAVE) training program.
• Fifty-five participants were randomized into a VR group (16 sessions over 8-10 weeks) or a control group (non-VR falls prevention).
• Primary outcome was fall incidence; secondary outcomes included cognition, executive function, gait, balance, and fear of falling.

Main Results:

• The VR group demonstrated significantly greater improvements in cognitive-motor performance compared to the control group.
• No significant differences were observed between groups in functional mobility and fall efficacy outcomes.

Conclusions:

• VR CAVE training offers promising results for fall risk reduction in older adults with MCI in Hong Kong.
• VR technology presents an emerging and valuable tool for contemporary aged care and rehabilitation services.
