简要总结
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.
详细描述
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.

结局指标
主要结局
Berg balance test (BBS) - change is being assessed
时间窗: At prettest, postest (up to 8 weeks) and post 3 months follow up
To test the balance performance and assess the fall risk. Total score is 56 ( score below 51 indicated predictive of fall risk)
Time up and go test (TUG) - change is being assessed
时间窗: At prettest, postest (up to 8 weeks) and post 3 months follow up
To assess functional mobility and assess the fall risk. Score over 12 seconds indicates higher risk of fall for the older adults
Six minutes walk test (6MWT) - change is being assessed
时间窗: At prettest, postest (up to 8 weeks) and post 3 months follow up
To assess the walking speed and performance. Walking distance within 6 minutes measured the length (m/metre)
次要结局
- Cognitive status assessed by Montreal Cognitive Assessment Scale- change is being assessed(At prettest, postest (up to 8 weeks) and post 3 months follow up)
- Executive functioning tests by Trail making test A and test B *TMTA/B) - change is being assessed(At prettest, postest (up to 8 weeks) and post 3 months follow up)
- Fall efficacy by fall efficacy international scale (FESI) - change is being assessed(At prettest, postest (up to 8 weeks) and post 3 months follow up)
