Analysis of forearm muscles activity by means of new protocols of multichannel EMG signal recording and processing
(Universitat Politècnica de Catalunya, 2012-12-20)
Doctoral thesis
Open AccessLos movimientos voluntarios del cuerpo son controlados por el sistema nervioso central y periférico a través de la contracción de los músculos esqueléticos. La contracción se inicia al liberarse un neurotransmisor sobre ... -
Analysis of muscle load-sharing in patients with lateral epicondylitis during endurance isokinetic contractions using non-linear prediction
(2019-09-24)
Article
Open AccessThe aim of this paper is to analyze muscle load-sharing in patients with Lateral Epicondylitis during dynamic endurance contractions by means of non-linear prediction of surface EMG signals. The proposed non-linear ... -

Evaluación de la Función Neuromuscular mediante Electromiografía Multicanal en Procesos de Rehabilitación motora
(2009)
Conference report
Open AccessLa posición y el movimiento del cuerpo están controlados por señales eléctricas que viajan desde y hacia el Sistema Nervioso Central, produciendo la contracción de los músculos voluntarios. Cuando se presenta una patología ... -
Evaluation of multiple comparison correction procedures in drug assessment studies using LORETA maps
(2015-10-01)
Article
Open AccessThe identification of the brain regions involved in the neuropharmacological action is a potential procedure for drug development. These regions are commonly determined by the voxels showing significant statistical differences ... -
High-density surface electromyography maps after computer-aided training in individual with congenital transverse deficiency: a case study
(2020-12-01)
Article
Open AccessBackground: The aim of this study was to determine whether computer-aided training (CAT) of motor tasks would increase muscle activity and change its spatial distribution in a patient with a bilateral upper-limb congenital ... -

(Nature, 2020-12)
Article
Open AccessThis paper presents a dataset of high-density surface EMG signals (HD-sEMG) designed to study patterns of sEMG spatial distribution over upper limb muscles during voluntary isometric contractions. Twelve healthy subjects ... -
High-density surface EMG maps from upper-arm and forearm muscles
(2012-12)
Article
Open AccessBackground sEMG signal has been widely used in different applications in kinesiology and rehabilitation as well as in the control of human-machine interfaces. In general, the signals are recorded with bipolar electrodes ... -
