Introduction: The use of virtual reality (VR) as a tool for health care, including rehabilitation of the elderly. With aging, physiological occur events that cause decreased brain processing efficiency and motor planning. However, little has been known about brain behavior, exposure of an RV, having a refined and accurate assessment, to support its use and clinical practice. Objective: To investigate the immediate effects of a practice of a balance game, performed in virtual environment, in the elderly, through the beta rhythm analysis in the frontal lobe. Methodology: A comparative study, involving 5 elderly individuals, initially evaluated by physiotherapeutic data and mini-exame of mental state. During the intervention the effects of cortical activity were recorded by Emotiv EPOC®. The game was divided in five moments, being one of rest and four main moments of stimulation of the game. Results: Significant differences were observed regarding the neural effort in several channels for the moments of the game (M0-M5,M0-M1, M2-M3, M3-M4 e M4-M5) and between the channels positioned parallel in the cerebral hemispheres for channels F3-F4 (z=19,675; p<0,001), F7-F8 (z=15,018; p<0,001) e FC5-FC6 (z=7,658; p<0,001). Significant difference was observed in mean power activation between pre-workout and post-workout moments. Conclusion: The use of virtual reality presents itself efficiently to provoke the immediate effects, it is not neural realized during a virtual reality in the elderly.
