Abstract Background: Postural control regulation involves sensory and cognitive process in organization and integration of motor information. It is common in daily routine to observe performance of cognitive and postural tasks simultaneously. Considering that cognition and postural control might require common central processing mechanisms, the simultaneous accomplishment of these tasks would become problematic if an individual's resources are depleted, resulting in lower performance in one task over the other. Objective: To verify if postural stability is affected by cognitive tasks and if cognitive performance is affected by postural tasks in children and young adults. Methods: Eighteen children between 8 and 11 years and 18 young adults between 20 and 35 years will be evaluated. In simple task condition participants will perform a primary postural task. They will be evaluated in static stand in four different conditions: parallel feet, narrow feet, parallel feet on the foam, and narrow feet on the foam. Inn dual task evaluation, participants will perform a primary task simultaneously with a cognitive task, which will involve an arithmetic activity. Dependent variables will be: Sample Entropy for postural control and number of responses (NR), number of errors (E) and number of right responses (NGR expressed by (NR-E) for cognitive task. To evaluate effects of postural and cognitive tasks on the groups a model of analysis of variance for repeated measures will be used with Tukey post hoc when necessary. We will adopt a 5% level of significance. Hypothesis: We hope that the addiction of a cognitive task in a postural one will deviate attention of postural task resulting in a less regular body oscillation, improving automatism of postural control. We hope mere pronounced influence in children given their reduced ability of central integration. | |
