Descrição
To evaluate the effect of exergames on postural control in older adults during single (ST) and dual (DT) tasks. A quasi-experimental study involving older adults enrolled in USP60+. Participants were allocated into control (CG, n=15, 66.5±6.3 years, 73.3% women) and training (TG, n=16, 67.1±4.6 years, 71.2% women) groups. Before and after the intervention, the oscillation of the center of pressure (COP) was recorded during ST and DT, using a portable force platform. Training was performed for 12 weeks (2x/week and 50 min/session). The deltas of the variables related to COP were calculated and the data was analyzed by non-parametric tests and biserial correlation (effect size). The significance level was set at p<0.05. COP sway was greater during DT, and the COP area (unstable surface + cognitive task) decreased in the TG after training. Body sway in older adults tends to be worse in dual tasks. Training with exergames improved postural sway in the TG, especially during complex dual-task activities.
