Background Stepping impairments are associated with physical and cognitive decline in older adults increased fall risk. Exercise interventions can reduce risk, but adherence is often low. A new exergame involving step training may provide an enjoyable exercise alternative for preventing falls people. Purpose To assess the feasibility safety of unsupervised, home-based pad determine effectiveness this intervention on stepping performance risk Design Single-blinded two-arm randomized controlled trial comparing control (no-intervention). Setting/Participants Thirty-seven residing independent-living units a retirement village Sydney, Australia. Intervention group (IG) participants were provided computerized system connected to their TVs played game as they liked (with recommended dose 2–3 sessions per week 15–20 minutes each) eight weeks. In addition, IG asked complete choice reaction time (CSRT) task once each week. Main Outcome Measures CSRT, Physiological Profile Assessment (PPA), neuropsychological functional mobility measures assessed at baseline follow-up. Results Thirty-two completed study (86.5%). median 2.75 sessions/week no adverse events reported. Compared group, significantly improved CSRT (F31,1 = 18.203, p<.001), PPA composite scores 12.706, p 0.001), well postural sway 4.226, 0.049) contrast sensitivity 4.415, 0.044) sub-component scores. dual-task ability by timed up go test/verbal fluency 0.049). Conclusions Step be safely undertaken home improve parameters people without major impairments. Trial Registration Australian New Zealand Clinical Trials Registry ACTRN12611001081909.
