RESUMO:

Introduction: In daily tasks the individuals need to perform simultaneous tasks such as walking and watching for obstacles, preventing accidents. However, morphological findings in elderly demonstrated a reduction in the gray matter of the frontal lobe, an important region for the execution of tasks that requires the executive function, like dual task performance. The electroencephalogram is used in the observation of brain dynamics by the capture of electrical flux. This flux is related to the activation of specific brain areas, responsible for specific functions. Bearing in mind this relationship, it can be said that the dual task training is an important tool to obtain motor and cognitive gains in elderly. Nevertheless, studies that demonstrate the brain patterns during the dual task performance are scarce. Thus, it is relevant to deploy an investigation of how the dual task performance can influence the brain activation pattern in elderly. Methodology: descritive observational study of transversal type, where 23 individuals between 65 and 75 years old were investigated. The subjects were submitted to a dual task activity through the Functional Ambulation Test, using the Emotiv EPOC for electroencephalographical analysis to observe the cortical activation during the dual task. Statistical analysis: the data were prepared by the statistical software SPSS-20. The analysis was made by the calculation of average, standard deviation and frequency. After the application of Shapiro-Wilk test – to verify the data normality – the data was submitted into the inferential statistical analysis under the Student T-test and Mann-Whitney, for parametrical and non-parametrical approaches, respectively. In correlation analysis, it was used the Pearson and Spearman tests.

Results: the duration of TDF1 test has average of 106.11±72.88 seconds. There was found a significant positive correlation between the TDF time and the age (p=<0,001; r= 0,49) and with MEEM (p<0,05; r=- 0,47). The comparative analysis between alpha and beta wave spectra highlighted slightly higher potentials in alpha frequency band (p=<0,001). The channels of cortical areas were the most activated ones. Conclusion: The obtained data points toward the fact that the dual task performance activated more the motor areas that contributes to executive functions to the detriment of the other cortical areas.
