Automatic jitter measurement in needle-detected motor unit potential trains
Malanda Trigueros, Armando ; Stashuk, Daniel W.; Navallas Irujo, Javier; Rodríguez Falces, Javier ; Rodríguez Carreño, Ignacio; Valle, César; Garnés Camarena, Óscar (Elsevier, 2022) Artículo / ArtikuluaIn an active motor unit (MU), the time intervals between the firings of its muscle fibers vary across successive MU activations. This variability is called jitter and is increased in pathological processes that affect the ... -
A deep learning image analysis method for renal perfusion estimation in pseudo-continuous arterial spin labelling MRI
Oyarzun Domeño, Anne; Cía Alonso, Izaskun; Echeverría Chasco, Rebeca; Fernández Seara, María A.; Martín Moreno, Paloma L.; García Fernández, Nuria; Bastarrika, Gorka; Navallas Irujo, Javier; Villanueva Larre, Arantxa (Elsevier, 2023) Artículo / ArtikuluaAccurate segmentation of renal tissues is an essential step for renal perfusion estimation and postoperative assessment of the allograft. Images are usually manually labeled, which is tedious and prone to human error. We ... -
EMG probability density function: a new way to look at EMG signal filling from single motor unit potential to full interference pattern
Navallas Irujo, Javier; Eciolaza Ferrando, Adrián ; Mariscal, Cristina; Malanda Trigueros, Armando ; Rodríguez Falces, Javier (IEEE, 2023) Artículo / ArtikuluaAn analytical derivation of the EMG signal's amplitude probability density function (EMG PDF) is presented and used to study how an EMG signal builds-up, or fills, as the degree of muscle contraction increases. The EMG PDF ... -
Long-range traffic monitoring based on pulse-compression distributed acoustic sensing and advanced vehicle tracking and classification algorithm
Corera Orzanco, Íñigo ; Piñeiro Ben, Enrique; Navallas Irujo, Javier; Sagüés García, Mikel ; Loayssa Lara, Alayn (MDPI, 2023) Artículo / ArtikuluaWe introduce a novel long-range traffic monitoring system for vehicle detection, tracking, and classification based on fiber-optic distributed acoustic sensing (DAS). High resolution and long range are provided by the use ... -
M-wave changes caused by brief voluntary and stimulated isometric contractions
Rodríguez Falces, Javier ; Malanda Trigueros, Armando ; Navallas Irujo, Javier; Place, Nicolas (Springer, 2023) Artículo / ArtikuluaIntroduction Under isometric conditions, the increase in muscle force is accompanied by a reduction in the fbers’ length. The efects of muscle shortening on the compound muscle action potential (M wave) have so far been ... -
Validation of the filling factor index to study the filling process of the sEMG signal in the quadriceps
Rodríguez Falces, Javier ; Malanda Trigueros, Armando; Mariscal, Cristina; Niazi, Imran Khan; Navallas Irujo, Javier (Elsevier, 2023) Artículo / ArtikuluaIntroduction: The EMG filling factor is an index to quantify the degree to which an EMG signal has been filled. Here, we tested the validity of such index to analyse the EMG filling process as contraction force was ...
