Hand motor fatigability induced by a simple isometric task in spinal cord injury
Onate-Figuérez, Ana; Soto-León, Vanesa; Avendaño-Coy, Alejandro; Mordillo-Mateos, Laura; Pérez-Borrego, Yolanda A.; Redondo-Galán, Carolina; Arias, Pablo; Oliviero, Antonio (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 ... -
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 ... -
Peripheral-Central Interplay for Fatiguing Unresisted Repetitive Movements: A Study Using Muscle Ischaemia and m1 Neuromodulation
Madinabeitia-Mancebo, Elena; Madrid López, Antonio; Oliviero, Antonio; Cudeiro, Javier; Arias, Pablo (Nature Research, 2021-01-22)[Abstract] Maximal-rate rhythmic repetitive movements cannot be sustained for very long, even if unresisted. Peripheral and central mechanisms of fatigue, such as the slowing of muscle relaxation and an increase in M1-GABAb ... -
Prevalence of Fatigue and Associated Factors in a Spinal Cord Injury Population: Data from an Internet-Based and Face-to-Face Surveys
Cudeiro-Blanco, Javier; Onate-Figuérez, Ana; Soto-León, Vanesa; Avendaño-Coy, Juan; Mordillo-Mateos, Laura; Brocalero-Camacho, Ángela; Esclarín-Ruz, Ana; Rotondi, Mario; Aguilar, Juan; Arias, Pablo; Oliviero, Antonio (Mary Ann Liebert, 2017-08-01)[Abstract] Fatigue has a profound impact on patients with spinal cord injury (SCI), but only limited treatments are available. The aim of this study was to determine the prevalence of fatigue in SCI and its association ... -
Temporal Dynamics of Muscle, Spinal and Cortical Excitability and Their Association With Kinematics During Three Minutes of Maximal-Rate Finger Tapping
Madinabeitia-Mancebo, Elena; Madrid López, Antonio; Jácome, M. A.; Cudeiro, Javier; Arias, Pablo (Springer Nature, 2020-02-21)[Abstract] We tested peripheral, spinal and cortical excitability during 3 minutes of unresisted finger tapping at the maximal possible rate, which induced fatigue. Subsequently, we studied the temporal dynamics of muscle ... -
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. ... -
Transcranial static magnetic field stimulation of M1 reduces corticospinal excitability without distorting sensorimotor integration in humans
Arias, Pablo; Adán-Arcay, Lucía; Puerta Catoira, Beatriz; Madrid, Antonio; Cudeiro, Javier (Elsevier, 2017-01-04) -
Transcranial static magnetic field stimulation of the human motor cortex
Oliviero, Antonio; Mordillo-Mateos, Laura; Arias, Pablo; Panyavin, Ivan; Foffani, Guglielmo; Aguilar, Juan (Wiley, 2001-08-01)[Abstract] The aim of the present study was to investigate in healthy humans the possibility of a non-invasive modulation of motor cortex excitability by the application of static magnetic fields through the scalp. Static ... -
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 ... -
Virtual Reality as a Tool for Evaluation of Repetitive Rhythmic Movements in the Elderly and Parkinson’s Disease Patients
Arias, Pablo; Robles-García, Verónica; Sanmartín, Gabriel; Flores, Julián; Cudeiro, Javier (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 ...
