The effect of virtual reality gaming on dynamic balance in older adults

BACKGROUND: physical therapy interventions that increase functional strength and balance have been shown to reduce falls in older adults. AIM: this study compared a virtual reality group (VRG) and a control group (CG). DESIGN: randomised controlled 6-week intervention with pre- and post-test evaluations. SETTING: outpatient geriatric orthopaedic and balance physical therapy clinic. POPULATION: forty participants were randomised into two groups. METHOD: the VRG received three different Nintendo® Wii FIT balance interventions three times per week for 6 weeks and the CG received no intervention. RESULTS: compared with the CG, post-intervention measurements showed significant improvements for the VRG in the 8-foot Up & Go test [median decrease of 1.0 versus -0.2 s, (P=0.038) and the Activities-specific Balance Confidence Scale (6.9 versus 1.3%) (P=0.038)]. CONCLUSION: virtual reality gaming provides clinicians with a useful tool for improving dynamic balance and balance confidence in older adults.
