RESUMO:

Dual-task activities are characterized by associating cognitive and motor tasks, leading to a greater demand of the neuromotor system for the perception, association and elaboration of an adequate response. Considering the physical, physiological and behavioral changes inherent in the aging process, it is believed that the performance of dual-task activities in the elderly has worse results when compared to younger subjects. In addition, dual-task activities in the elderly are linked to a greater predisposition to falls, a fact that configures a serious public health problem due to the high rates of mortality and morbidity in this population. But despite the several characteristic losses of aging. Thus, knowledge of the brain behavior of the elderly during performance in dual-task activities and the elucidation of an intervention with a better ability to modify their brain activation pattern becomes relevant to improve functional independence in this population. The present study aimed to investigate the influence of an exercise program based on virtual reality on the pattern of brain activation and on the performance of dual task activity in the elderly. A quasi-experimental comparative study with an elderly population (65-75 years), whose sample consisted of 13 subjects of both genders who underwent brain mapping evaluation using the Emotiv EPOC Electroencephalography device during the performance of the Functional Ambulation Test (PTO). After the evaluation, the subjects were randomized into 2 groups, being the experimental group (virtual reality exercises) and the control group (conventional exercises), and completed a 12-week exercise program twice a week. After the protocol was concluded, the subjects were reevaluated following the same criteria of the pre-intervention evaluation. The data captured by the EEG were processed and considered the potential values for the alpha and beta waves. The potentials were tabulated in the SPSS-19 and considering the normalization of the data, the paired t-test was used to compare the means in the pre and post intervention conditions. The data obtained in the performance of the dual task activity (performance time and number of errors) were compared using the Wilcoxon test, considering the non-normal distribution by the Shapiro Wilk test. For the performance in the dual task activities, the results show that: In the DT1 activity, the control group showed a significant reduction in the performance time; For DT2 activity, the experimental group showed a significant reduction in the number of errors. Regarding brain mapping, the results showed a significant increase in the alpha wave in the FC6 area, equivalent to the primary motor cortex, and a significant reduction in the beta wave in the right prefrontal (AF4) and left somatosensory and association cortex (P7) areas. , for the control group, only during the performance of DT1. Thus, from the results found, we conclude that the conventional exercise program was able to express a more significant change in the cortical activation pattern of the investigated subjects when compared to the virtual reality exercise program.
