Ageing Effects on Dual-Tasking Performance that Involved Turning-While-Walking

Abstract

Turning-while-walking requires attention. This task can demand more attention when performed with a concurrent cognitive task, particularly in older adults. This study therefore aimed at examining the effects of ageing on dual-tasking performance that involves turning-while-walking in youngold adults (age 65-74). Eleven young-old adults and ten young adults were recruited. Single auditory Stroop test, single turning-while-walking test, and dual-tasking that combined the two single tests were assessed. Results showed that young-old adults compromised accuracy in cognitive task when dualtasking, while their physical task performance was not significantly affected by an additional cognitive task. The results suggested that the young-old adults could have employed a ‘posture first’ strategy to maintain balance when there were insufficient attentional resources for them to perform the two tasks simultaneously. When compared to the young subjects, the young-old adults performed similarly during the physical task. However, they reacted significantly slower than their younger counterparts in the cognitive task when dual-tasking. The results raise concerns regarding the dual-tasking ability of communitydwelling young-old adults, even if they appear to be physically fit. Future studies incorporating different cognitive tasks are warranted. Correlation between dualtasking ability, physical function, cognitive function, and activity level are also worth investigating.
