Virtual Reality Activity-based Training for Preventing Falls for Older Adults With Mild Cognitive Impairment

Virtual Reality Activity-based Training for Preventing Falls Among Community-dwelling Older Adults With Mild Cognitive Impairment: A Pilot Randomized Control Trial Study

Using a Virtual Reality (VR) games-based application is as an innovative falls prevention technology in an aged care service. The VR intervention has promising effects on improving the physical and balance performances in the older adults.The study explored and evaluated the effects of VR activity-based training on falls prevention among community-dwelling older adults with mild cognitive impairment.

A pilot randomized control trial study was applied to compare the effects on falls prevention between participants who experienced a full-immersive VR training and group-based exercise (Baduanjin) training. Eighteen participants were recruited from ausing convenience sampling and were randomly assigned into the VR group and the exercise group (non-VR). The participants in both wo groups' participants attended 16 falls prevention training sessions over eight weeks. Eligible participants identified with a higher risk of mild cognitive impairment and early dementia undertook three measurements, pretest (T1), post-test (T2) and follow up (T3). The primary outcomes assessed included changes in physical risks factor of falls, and the secondary outcomes assessed included changes in cognition and fall efficacy.
