“…Uncertainty about the nature of an upcoming perturbation to upright stance has been shown to lead to poor reactive postural responses in both young [1] and older [2] individuals. The effect of uncertainty on reactive postural responses suggests that muscular activation to restore stable upright stance following balance perturbation is mediated by higher order processing.…”

“…Both implicit knowledge learned from trial repetition with similar motion characteristics, or explicit prior warning in task constraints (e.g., perceived velocity of an approaching ball), can influence postural control mechanisms during catching (Tijtgat, Bennett, Savelsbergh, De Clercq, & Lenoir 2010 and upright standing (Aimola, Santello, La Grua, & Casabona, 2011;de Lima, de Azevedo Neto, & Teixeira 2010). Tijtgat et al (2012) showed that, during a catching task, provision of explicit advanced knowledge of ball velocity enabled a more functional scaling of arm movement during the transport phase, with the initial motor response adapting to the expected ball speed.…”

“…Estudos prévios já tinham descrito essa relação em postura estática (Morioka et al, 2005) e em postura perturbada (de Lima et al, 2010). Pesquisas prévias do nosso grupo de estudos (De Lima-Pardini, 2013) relatam também condições de tarefa dual com dois níveis de dificuldade na tarefa secundária.…”

“…Este é o caso de pesquisas com tarefa dual que investigaram uma tarefa primária postural e uma tarefa secundária voluntária de caráter predominantemente motor (Kubicki, Petrement, Bonnetblanc, Ballay & Mourey, 2011;Elion, Bahat & SievNer, 2013). Tarefas voluntárias como apontar para um alvo (Kubicki et al, 2011;Elion et al, 2013), equilibrar um taco de madeira no dedo (Cluff, Gharib, & Balasubramaniam, 2010) ou segurar uma bandeja com um objeto (Morioka, Hiyamizu, & Yagi, 2005;de Lima, de Azevedo Neto, & Teixeira, 2010; podem se beneficiar com melhor desempenho quando realizadas com outra tarefa, nomeadamente a tarefa de manutenção da postura ereta. Assim, a atenção alocada para o sucesso do desempenho da tarefa manual permitiu melhor desempenho postural, e esse melhor desempenho postural contribuiu para melhorar o desempenho na tarefa de estabilidade manual.…”
