Dual-task interference: Attentional and neurophysiological influences
(ELSEVIER SCIENCE BV, 2009)
Performing two tasks simultaneously often degrades performance of one or both tasks. While this dual-task interference is classically interpreted in terms of shared attentional resources, where two motor tasks are performed ...
Effects of A Dual-Task Intervention in Postural Control and Cognitive Performance in Adolescents
The aim was to assess dual- versus single-task training for motor performance and cognitive performance in adolescents. Two experiments were performed. In the first, 30 adolescents were randomized to three groups to determine ...
Influence of dual-task constraints on the interaction between posture and movement during a lower limb pointing task
One of the challenges regarding human motor control is making the movement fluid and at a limited cognitive cost. The coordination between posture and movement is a necessary requirement to perform daily life tasks. The ...
Obstacle Crossing with Dual Tasking is a Danger for Individuals with Alzheimer's Disease and for Healthy Older People
(Ios Press, 2015-01-01)
Background/Objective: The aim of this study was to analyze the effects of dual tasking on obstacle crossing during walking by individuals with Alzheimer's disease (AD) and by healthy older people.Methods: Thirty four elderly ...
Dual task interference on postural sway, postural transitions and gait in people with Parkinson's disease and freezing of gait
Freezing of gait (FoG) is associated with less automatic gait and more impaired cognition, balance and postural transitions compared to people with PD who do not have FoG. However, it is unknown whether dual-task cost ...
On the functional integration between postural and supra-postural tasks on the basis of contextual cues and task constraint
(ELSEVIER IRELAND LTD, 2010)
In order to evaluate the effects of uncertainty about direction of mechanical perturbation and supra-postural task constraint on postural control young adults had their upright stance perturbed while holding a tray in a ...
Gait and risk of falls associated with frontal cognitive functions at different stages of Alzheimer's disease
(Psychology PressHoveInglaterra, 2012)
Efeitos de tarefas cognitivas no controle postural de idosos: Uma revisão sistemática
Demanding attention in order to keep postural balance increases with aging and with the presence of concurrent tasks that require information processing. Several studies have demonstrated that motor performance can be ...
Understanding dual task performance in humans : electrophysiological correlates of interferences and costs between motor and working memory tasks at different levels of workload
The simultaneous execution of two different tasks is associated with interference processes that produce a decrease in the performance of one or both duties, a common phenomenon whose neural mechanisms are not yet ...
