Abstract

Aims: The objective was to evaluate the electrical cortical activity during two static and two dynamic tasks, comparing between tasks with single support tasks and tasks with two feet on the platform.

Settings and Design: Sixteen young males participated in this cross-sectional study.

Methods and Material: Electrical cortical activity was assessed using the Enobio device. Two static and two dynamic tasks were performed, all of them on the Biodex Balance System device.

Statistical analysis used: Mean power spectrum for the Alpha band was analyzed. The Wilcoxon signed rank test was used to compare tasks with one single support and tasks with the two feet on the platform.

Results: No significant difference was observed when comparing the balance tasks.

Conclusions: The number of supports did not significantly modify the EEG signal in the alpha band. However, cognitive demands in the single support dynamic task seemed to be somewhat higher compared with the rest of the tasks. These results may be relevant to design future programs based on dual task.
