RESUMO:

Introduction: During the aging process, there are physiological changes that promote a less efficient brain processing and motor planning, especially when compared to young individuals. In recent years, virtual reality (VR) has become more popular and has been increasingly utilized in rehabilitation centers as an additional health care tool, including for elderly. Because it is considered a motivating resource that promotes greater adhesion to treatment, RV has quickly spread. Nevertheless, there is little knowledge about how the use of game therapy influences the brain activation of different groups subjected to such stimulation. Faced with the diverse cognitive and motor demands provided by this type of resource, alternate mechanisms, such as portable electroencephalography equipment, are essential to measure how brain activity behaves in response to such exposure. Objective: The aim of this study is to investigate the immediate outcomes of performing a balance game, in virtual environment, in brain activation of frontal lobes of young adults. Methodology: comparative study, involving 20 individuals divided into two groups: young (YG) and elderly (EG). After being submitted to an evaluation of general condition, the necessary support for gait task, and cognitive status, the participants, during 4 minutes, practiced the penguin slide game of the Nintendo Wii balance category, whose effects on the cortex activity were observed through Emotiv EPOC’s acquired data. Results: The alpha wave frequency presented a greater activation power in both groups. To compare the activation power between the groups, the Mann-Whitney test was performed which did not show statistical differences between the alpha (p = 0.58) and beta (p = 0.92) frequency bands. Descriptively, it is possible to verify a tendency of GI to activate the right hemisphere channels more, while the opposite is observed in the GJ. Conclusion: Activation of alpha and beta waves in the frontal canals for young and elderly individuals does not differ when they undergo an RV experience.
