Desempenho de idosos em uma tarefa motora de demanda dupla de controle

Abstract: A literatura sobre o processo de envelhecimento tem sistematicamente demonstrado a diferença de desempenho entre populações jovens e idosas. Em geral, os delineamentos de pesquisa envolvem indivíduos de 60 e até mesmo de 90 anos de idade, enquanto o grupo de jovens é representado por indivíduos em torno de 20 anos de idade. Esse procedimento pode ocultar mudanças de desenvolvimento que talvez influencie a interpretação dos resultados. Assim, o objetivo desse estudo foi examinar o efeito da idade cronológica no… Show more

“…12 Another relevant factor is that elderly individuals have greater difficulty in performing a DT than younger individuals. 13 Walking is a complex motor task, with limited involvement of cognitive control, and its performance is considered automatic in healthy adults, although this automatism is lost in old age. 4,14 The aging process is accompanied by alterations in the spatial and temporal parameters of gait, 14 such as reductions in gait speed and step length, as well as increases in step variability, double support time and step width, 4,12,15 all of which have been correlated with a higher incidence of falls.…”

“…The dual task demanded during the training might therefore be responsible for the result observed for the OPG. In addition, an elderly population might present a decreased capacity for executing the dual task due to distractions and low motivation with only partial use of the capacity of their Central Nervous System (Gehring et al, 2009). As the simultaneous task processing becomes more complex, this might have caused a deficit in the postural stability, thus influencing equilibrium, which possibly was reflected in the BBS values obtained.…”
