MCI: Virtual Reality Activity-based Training for Preventing Falls for Older Adults With Mild Cognitive Impairment
Study Details
Study Description
Brief Summary
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.

Detailed Description
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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: VR group VR activity-based training |
Other: VR activity-based
VR games activities were chosen for simulated cognitive-motor training in the VR group. The VR training modules for this study included fire drill, walking exercise, balancing game activities and community shopping practices. These training modules involved dual task components; the participant was expected to train up his/her physical and cognitive motor performances in an 8-week VR activity-based program. VR group participants received 2-sessions per week, 16 training sessions in total.

| Active Comparator: Exercise group Exercise-based training (Baduanjin) |
Other: Exercise-based (Baduanjin)
The exercise group used a traditional Chinese Qigong Baduanjin exercise incorporating with a fall prevention education strategy.

Outcome Measures
Primary Outcome Measures
- Berg balance test (BBS) - change is being assessed [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 [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 [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)
Secondary Outcome Measures
- 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]
To assess the cognitive level. Total score 30 ( score if less than 22 indicated higher risk of midl cognitive impairment
- 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]
To assess the level of executive functions. It indicated the time of completion (second)
- 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]
To assess the level of fear concern. Totoal score is 64 (score lower than 27 indicated less fear concern
