The effects of concurrent cognitive tasks on postural sway in healthy subjects Abstract Introduction: Keeping balance of the upright stance is a highly practiced daily task for healthy adults and is effectively performed without overt attentional control in most. Objective: The purpose of this study was to examine the influence of concurrent cognitive tasks on postural sway in healthy participants. Methods: This was a prospective study. 20 healthy volunteer subjects were included. The cog-nitive and balance tasks were performed separately and then, concurrently. Postural control task consisted of 6 conditions (C) of the Sensory Organization Test. The cognitive task consisted of digit rehearsal task of varying presentation and varying levels of difficulty. Results: A statistically significant difference was noted between dual task and no task for C1, C2, C3 and C4 Sensory Organization Test scores (p < 0.05). There was no statistically significant difference between dual task versus non-task for C5, C6 and combined Sensory Organization Test scores (p > 0.05). Conclusion: During dual task, increase has been determined in postural sway for C1, C2, C3 and C4 for all presentation modes and difficulty levels of the cognitive tasks.

Objetivo: A finalidade deste estudo foi examinar a influência de tarefas cognitivas concomi-tantes no equilíbrio postural de indivíduos saudáveis. Método: Trata-se de um estudo prospectivo em que participaram 20 voluntários saudáveis. As tarefas cognitivas e de equilíbrio foram realizadas separadamente; e em seguida, real-izadas simultaneamente. A tarefa de controle postural consistiu em seis condições (C) do Teste de Organização Sensorial (TOS). A tarefa cognitiva consistiu na repetição de dígitos com apresentações variadas e vários níveis de dificuldade. Resultados: Houve diferença estatisticamente significante entre os escores do TOS para as condições C1, C2, C3 e C4 para ''dupla tarefa'' vs. ''não tarefa'' (p < 0,05). Não houve diferença estatisticamente significante entre os escores do TOS para as condições C5 e C6 e para a combinação dos escores do TOS para ''dupla tarefa'' vs. ''não tarefa'' (p > 0,05). Conclusão: Durante a realização de dupla tarefa, foram determinados aumentos na oscilação postural para as condições C1, C2, C3 e C4 …
