Considering neurophysiological mechanisms of dual-tasking in people with multiple sclerosis: an exploratory, cross-sectional small-N study

Frontiers in Neurology
IntroductionDual-tasking is an emerging topic of study within the field of multiple sclerosis (MS) rehabilitation. Past research on dual-task performance among people with MS (PwMS) is limited by methodological differences and minimal consideration of ...

Dual-task interference: Attentional and neurophysiological influences

, 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 simultaneously interactions ...

Measuring Attentional Demand in Continuous Dual-task Performance

The Quarterly Journal of Experimental Psychology Section A, 1997
Despite its intuitive appeal, the commonly held assumption that there is some general limitation on dual-task performance has been shown to be seriously flawed (Allport 1980; Navon 1984). Central to this has been the inability to measure the attentional demands of tasks, without which there is no way to determine whether their joint demands exceed the ...

Evaluating the impact of task-sequencing on cognitive and motor performance in MS: PASAT and 3-minute walk test order effects

Frontiers in Neurology
IntroductionCognitive-motor functioning in persons with Multiple Sclerosis (PwMS) may be studied effectively by means of dual-task paradigms, under which potential impairments may become more salient.

Effects of single- and dual-task training on dual-task walking performance, prosthetic-limb dynamics and quality of life in unilateral transtibial amputees

Frontiers in Sports and Active Living
IntroductionThe aim of the study was to compare the effects of single-task versus dual-task training on dual-task walking performance, prosthetic-limb kinematics, centre-of-pressure behaviour, and health-related quality of life in adults with transtibial

Cognitive-motor interference in people with essential tremor

Scientific Reports
Adapting to different environments throughout daily activities requires flexibility in allocating attention. Compromised dual-tasking can hinder mobility, increase fall risk, and decrease functional independence in patients with essential tremor, who ...
