Controlled trial of balance training using a video game console in community-dwelling older adults.

backgroundgamification is a potentially attractive option for improving balance and reducing falls.

objectivesto assess the effect of balance training using the NintendoTM Wii game console on balance (primary outcome), falls and fear of falling.

designquasi-randomised, open-label, controlled clinical trial in parallel groups, carried out on community-dwelling patients over 70 years, able to walk independently. Participants were assigned 1:1 to the intervention or control group. Balance training was conducted using the Nintendo WiiFitTM twice a week for 3 months. Balance was assessed using the Tinetti balance test (primary outcome), the unipedal stance and the Wii balance tests at baseline, 3 months and 1 year. Falls were recorded and Fear of falling was assessed by the Falls Efficacy Scale (Short-FES-I).

results1,016 subjects were recruited (508 in both the intervention and the control group; of whom 274 and 356 respectively completed the 3-month assessment). There was no between-group difference in the Tinetti balance test score, with a baseline mean of 14.7 (SD 1.8) in both groups, and 15.2 (1.3) at 3 months in the intervention group compared to 15.3 (1.7) in controls; the between-group difference was 0.06 (95% CI 0.30-0.41). No differences were seen in any of the other balance tests, or in incident falls. There was a reduction in the fear of falling at 3 months, but no effect at 1 year.

conclusionsthe study found no effect of balance training using the NintendoTM Wii on balance or falls in older community-dwelling patients.The study protocol is available at clinicaltrials.gov under the code NCT02570178.
