Effects of movement imitation training in Parkinson's disease: a virtual reality pilot study
(Elsevier, 2016-05)
[Abstract] Background. Hypometria is a clinical motor sign in Parkinson's disease. Its origin likely emerges from basal ganglia dysfunction, leading to an impaired control of inhibitory intracortical motor circuits. Some ...
Fatigue insights from walking tests in spinal cord injury and multiple sclerosis individuals
(Springer Nature, 2024-02-27)
[Abstract] In the last decade, fatigue in clinical populations has been re-conceptualized, including dimensions such as perceived fatigue (trait and state fatigue) and fatigability. The aim of this study was to evaluate ...
Hand motor fatigability induced by a simple isometric task in spinal cord injury
(MDPI, 2022-08-30)
[Abstract] This study aimed: (1) to evaluate the hand motor fatigability in people with spinal cord injury (SCI) and compare it with measurements obtained form an able-bodied population; (2) to compare the hand motor ...
Exploring the role of the left DLPFC in fatigue during unresisted rhythmic movements
(Wiley, 2022-04-16)
[Abstract] Understanding central fatigue during motor activities is important in neuroscience and different medical fields. The central mechanisms of motor fatigue are known in depth for isometric muscle contractions; ...
Balancing the excitability of M1 circuitry during movement observation without overt replication
(Frontiers, 2014-09-17)
[Abstract] Although observation of a movement increases the excitability of the motor system
of the observer, it does not induce a motor replica. What is the mechanism for
replica suppression? We performed a series of ...
Bilateral tDCS on primary motor cortex: effects on fast arm reaching tasks
(PLoS, 2016-08-04)
[Abstract] Background.
The effects produced by transcranial direct current stimulation (tDCS) applied to the motor system have been widely studied in the past, chiefly focused on primary motor cortex (M1) excitability. ...
Central fatigue induced by short-lasting finger tapping and isometric tasks: a study of silent periods evoked at spinal and supraspinal levels
(Elsevier, 2015-08-01)
[Abstract] The neural substrates of fatigue induced by muscular activity have been addressed in depth in relation to isometric tasks. For these activities, when fatigue develops, it has been noted that the duration of the ...
Low-cost virtual reality system in evaluation of rhythmic motor patterns in elderly and Parkinsonian patients
(MIT Press, 2014-04-30)
[Abstract] This work details a Virtual Reality (VR) system developed to evaluate
and potentially treat alterations in hand movements and central rhythm
formation in Parkinsonian and Elderly subjects. An essential feature ...
The effects of expectancy on corticospinal excitability: passively preparing to observe a movement
(American Physiological Society, 2014-01-08)
[Abstract] The corticospinal tract excitability is modulated when preparing movements. Earlier to movement execution, the excitability of the spinal cord increases waiting for supraspinal commands to release the movement. ...
Virtual Reality as a Tool for Evaluation of Repetitive Rhythmic Movements in the Elderly and Parkinson’s Disease Patients
(PLoS ONE, 2012-01-18)
[Abstract] This work presents an immersive Virtual Reality (VR) system to evaluate, and potentially treat, the alterations in rhythmic
hand movements seen in Parkinson’s disease (PD) and the elderly (EC), by comparison ...
