Introduction: :
Falls are the leading cause of injury in older adults and pose a significant public health issue due to their high incidence and recurrence. Potential complications, including functional dependence and fear of falling, can lead to physical frailty and institutionalization. Emerging evidence indicates the potential benefits of virtual reality (VR) in rehabilitation.
Objectives: :
This pilot study aims to investigate the effects of VR training on fall prevention, specifically focusing on functional independence and self-perceived confidence in avoiding falls.
Methodology: :
A total of 26 fall patients were recruited through convenience sampling from the Occupational Therapy Department of Geriatric Day Hospital in Lai King Building since October 2024. This pilot study compared the treatment effects of two groups: a control group receiving 60 minutes of conventional rehabilitation per session, and a VR group receiving 40 minutes of conventional rehabilitation followed by 20 minutes of VR training using the Kine-Sim system. The Kine-Sim system is equipped with bilateral motion platforms that provide simulated synchronized movements tailored to the patients’ routines, interests, and deficits. All patients underwent an average of 20 treatment sessions. Outcome measures for functional independence (Modified Barthel Index, MBI) and self-perceived confidence in avoiding falls (Fall Efficacy Scale, FES) were assessed at baseline and upon discharge.
Result & Outcome: :
The VR group demonstrated a significant improvement in the MBI (p = 0.02) and FES (p = 0.012). The control group showed similar results for MBI (p = 0.02) but an insignificant improvement in FES (p = 0.108). Comparatively, the VR group exhibited better improvements in MBI (mean difference: 11.5 vs. 5.9) and FES (mean difference: 7.1 vs. 4.8), though these differences were not statistically significant (MBI: p = 0.053, FES: p = 0.252). The integration of VR training into geriatric fall rehabilitation appears to enhance motivation and may improve clinical effectiveness compared to conventional rehabilitation alone, particularly in helping patients maintain functional independence and build confidence in avoiding falls.
