Antagonist muscle co-activation during straight walking and its relation to kinematics: Insight from young, elderly and Parkinson's disease
Arias, Pablo; Espinosa, Nelson; Robles-García, Verónica; Cao, Ricardo; Cudeiro, Javier (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 ... -
Balancing the excitability of M1 circuitry during movement observation without overt replication
Arias, Pablo; Robles-García, Verónica; Corral Bergantiños, Yoanna; Espinosa, Nelson; Mordillo-Mateos, Laura; Grieve, Kenneth; Oliviero, Antonio; Cudeiro, Javier (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
Arias, Pablo; Corral Bergantiños, Yoanna; Robles-García, Verónica; Madrid, Antonio; Oliviero, Antonio; Cudeiro, Javier (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
Arias, Pablo; Robles-García, Verónica; Corral Bergantiños, Yoanna; Madrid, Andy; Espinosa, Nelson; Valls-Solé, Josep; Grieve, Kenneth; Oliviero, Antonio; Cudeiro, Javier (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 ... -
Effect of Stimulation Timing on Testing Voluntary Muscle Force Generation
Madrid López, Antonio; Madinabeitia-Mancebo, Elena; Robles-García, Verónica; Chouza-Insua, Marcelo; Cudeiro, Javier; Arias, Pablo (Elsevier, 2020-10-08)[Abstract] Background. The interpolated twitch technique (ITT) is a ubiquitous test for assessing the level of voluntary muscle force generation, in which muscle twitches are evoked via percutaneous electrical stimulation. ... -
Effects of early or late-evening fatiguing physical activity on sleep quality in non-professional sportsmen
Arias, Pablo; Madinabeitia-Mancebo, Elena; Santiago, Miguel; Corral Bergantiños, Yoanna; Robles-García, Verónica (Edizioni Minerva Médica, 2016-05-01)[Abstract] Background: This study aims to understand whether night sleep-quality is distorted by fatiguing physical activity (PA) when conducted early or late in the evening. Methods: Nine males (18-38yrs) performed ... -
Effects of movement imitation training in Parkinson's disease: a virtual reality pilot study
Robles-García, Verónica; Corral Bergantiños, Yoanna; Espinosa, Nelson; García-Sancho, Carlos; Sanmartín, Gabriel; Flores, Julián; Cudeiro, Javier; Arias, Pablo (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 ... -
Low-cost virtual reality system in evaluation of rhythmic motor patterns in elderly and Parkinsonian patients
Sanmartín, Gabriel; Flores, Julián; Robles-García, Verónica; Arias, Pablo; Cudeiro, Javier (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 ... -
Motor facilitation during real-time movement imitation in Parkinson’s disease: a virtual reality study
Robles-García, Verónica; Arias, Pablo; Sanmartín, Gabriel; Espinosa, Nelson; Flores, Julián; Grieve, Kenneth; Cudeiro, Javier (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 ... -
Spatiotemporal gait patterns during overt and covert evaluation in patients with Parkinson’s disease and healthy subjects: is there a hawthorne effect?
Robles-García, Verónica; Corral Bergantiños, Yoanna; Espinosa, Nelson; Jácome, M. A.; García-Sancho, Carlos; Cudeiro, Javier (Human Kinetics, 2015)[Abstract] Parkinson's disease (PD) and aging lead to gait impairments. Some of the disturbances of gait are focused on step length, cadence, and temporal variability of gait cycle. Under experimental conditions gait can ... -
The effects of expectancy on corticospinal excitability: passively preparing to observe a movement
Arias, Pablo; Robles-García, Verónica; Espinosa, Nelson; Corral Bergantiños, Yoanna; Mordillo-Mateos, Laura; Grieve, Kenneth; Oliviero, Antonio; Cudeiro, Javier (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?
Arias, Pablo; Robles-García, Verónica; Espinosa, Nelson; Corral Bergantiños, Yoanna; Cudeiro, Javier (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 ...
