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 ... -

Controlled trial on the effect of 10 days low-frequency repetitive transcranial magnetic stimulation (rTMS) on motor signs in Parkinson´s disease
Arias, Pablo; Vivas-Costa, Jamile; Grieve, Kenneth; Cudeiro, Javier (Wiley, 2010-07-28)[Abstract] We evaluated the effect of low-frequency rTMS on motor signs in Parkinson’s disease (PD), under a doubleblind placebo-controlled trial design. PD patients were randomly assigned to received either real (n 5 ... -
Differential responses of spinal motoneurons to fatigue induced by short-lasting repetitive and isometric tasks
Madrid, Antonio; Valls-Solé, Josep; Oliviero, Antonio; Cudeiro, Javier; Arias, Pablo (Elsevier, 2016-10-24)[Abstract] Compared to isometric activities, the neural basis of fatigue induced by repetitive tasks has been scarcely studied. Recently, we showed that during short-lasting repetitive tasks at the maximal possible rate ... -
Double-blind, randomized, placebo controlled trial on the effect of 10 days low-frequency rTMS over the vertex on sleep in Parkinson’s disease
Arias, Pablo; Vivas-Costa, Jamile; Grieve, Kenneth; Cudeiro, Javier (Elsevier, 2010-07-31)[Abstract] Objective: A recent report indicates repetitive transcranial magnetic stimulation (rTMS) improves sleep in Parkinson’s disease (PD). The aim of this work is to evaluate the effect of 10 days rTMS on sleep ... -
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 a finger tapping fatiguing task on M1-intracortical inhibition and central drive to the muscle
Madrid, Antonio; Madinabeitia-Mancebo, Elena; Cudeiro, Javier; Arias, Pablo (Nature, 2018)[Abstract] The central drive to the muscle reduces when muscle force wanes during sustained MVC, and this is generally considered the neurophysiological footprint of central fatigue. The question is if force loss and the ... -
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 ... -

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 ... -
