Motor facilitation during real-time movement imitation in Parkinson’s disease: a virtual reality study
(Elsevier, 2013-08-06)
[Abstract] Background: Impaired temporal stability and poor motor unit recruitment are key impairments in Parkinsonian motor control during a whole spectrum of rhythmic movements, from simple finger tapping to gait. Therapies ...
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 ...
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 ...
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. ...
Validity of the finger tapping test in Parkinson’s disease, elderly and young healthy subjects: is there a role for central fatigue?
(Elsevier, 2012-05-03)
[Abstract] Objective: The main goal of this work is to evaluate the validity of the finger tapping test (FT) to detect alterations in rhythm formation.
Methods: We use FT to study the alterations in motor rhythm in three ...
Antagonist muscle co-activation during straight walking and its relation to kinematics: Insight from young, elderly and Parkinson's disease
(Elsevier, 2012-03-21)
[Abstract] Increased antagonist muscle co-activation of the lower limb during walking seems to be an
adaptive process to the physiological changes of aging, in order to gain joint stability. In the
healthy subjects this ...
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 ...
