Purpose: As many older people fall during dual tasks, we aimed to examine the effect of different cognitive loads on learning gait stability in younger and older adults. Methods: 10 younger (Mean±SD age: 25.91±3.42 years) and 10 older adults (Mean±SD: 66.65±4.28 years) were healthy volunteers without a history of falls. They were asked to do three tasks on a treadmill with cognitive load (none...

Background. Parkinson’s disease (PD) is characterized by motor and non-motor symptoms that affect patients’ functional performances, especially while performing dual tasks which is a critical factor in connection with everyday living. There are many controversies about the benefits. Objectives. This study assessed the efficacy of motor and cognitive dual-task training programs for improving of ...

Aging and dual-task paradigms often degrade fine motor performance, but the effects of aging on correlated neural activity between motor cortex and contracting muscle are unknown during dual tasks requiring fine motor performance. The purpose of this study was to compare corticomuscular coherence between young and elderly adults during the performance of a unilateral fine motor task and concurr...

objective neuropsychological impairment is an important co-morbidity of chronic epilepsy. the aim of this study was to determine the state of the cognitive and motor development of patients with refractory epilepsy. materials & methods  we studied 150 consecutive children with epilepsy who were referred to mofid children hospital, a third level public referral university hospital in tehran, ira...

I review a variety of behavioral studies directed at understanding how probability and value information is represented in motor and cognitive tasks. Subjects in (cognitive) decision-making tasks often misrepresent the frequency of rare events and typically fail to maximize expected gain. In contrast, subjects in mathematically equivalent movement tasks are generally found to be very good at ch...
