Canonical maximization of coherence: a novel tool for investigation of neuronal interactions between two datasets
Vidaurre, Carmen
; Nolte, Guido; Vries, I. E. J. de; Gómez Fernández, Marisol ; Boonstra, Tjeerd W.; Müller, Klaus Robert; Villringer, Arno; Nikulin, Vadim V. (Elsevier, 2019)
Artículo / Artikulua 
Synchronization between oscillatory signals is considered to be one of the main mechanisms through which neuronal populations interact with each other. It is conventionally studied with mass-bivariate measures utilizing ... -
Computation of greatest common divisor for the blind deconvolution of transient impulsive signals
Lecumberri Villamediana, Pablo; Gómez Fernández, Marisol ; Carlosena García, Alfonso (Universitat Politècnica de Catalunya, 2005)
Contribución a congreso / Biltzarrerako ekarpena
We propose a new blind deconvolution method for transient impulsive signals in a single input – multiple output (SIMO) system. The method exploits the data redundancy inherent to SIMO multichannel systems to obtain an ... -
Design of low-cost smart accelerometers
Carlosena García, Alfonso; López Martín, Antonio ; Massarotto, Marco ; Cruz Blas, Carlos Aristóteles de la ; Lecumberri Villamediana, Pablo ; Gómez Fernández, Marisol ; Pintor Borobia, Jesús María ; Gárriz Sanz, Sergio (Universitat Politècnica de Catalunya, 2005)
Artículo / Artikulua
The goal of this project is to design a low-cost smart accelerometer, making use of a piezoelectric element as basic sensing material, and adding a mixed-mode conditioning circuit. -
Enhancing sensorimotor BCI performance with assistive afferent activity: an online evaluation
Vidaurre, Carmen; Ramos Murguialday, Ander; Haufe, Stefan; Gómez Fernández, Marisol ; Müller, Klaus Robert; Nikulin, Vadim V. (Elsevier, 2019)
Artículo / Artikulua
An important goal in Brain-Computer Interfacing (BCI) is tofind and enhance procedural strategies for users for whom BCI control is not sufficiently accurate. To address this challenge, we conducted offline analyses and ... -
An evaluation of the 30-s chair stand test in older adults: frailty detection based on kinematic parameters from a single inertial unit
Millor Muruzábal, Nora; Lecumberri Villamediana, Pablo ; Gómez Fernández, Marisol ; Martínez Ramírez, Alicia ; Izquierdo Redín, Mikel (BioMed Central, 2013)
Artículo / Artikulua
Background: A growing interest in frailty syndrome exists because it is regarded as a major predictor of co-morbidities and mortality in older populations. Nevertheless, frailty assessment has been controversial, particularly ... -
Frailty assessment based on the instrumented version on the 30-s chair stand test
Millor Muruzábal, Nora (2015)
Tesis doctoral / Doktoretza tesia
El objetivo de esta tesis es mejorar la evaluación de la capacidad funcional usando nuevos parámetros cinemáticos. Así, el personal clínico dispondrá de una serie de medidas objetivas y cuantificables para realizar sus ... -
Frailty assessment based on trunk kinematic parameters during walking
Martínez Ramírez, Alicia; Martinikorena Aranburu, Ion ; Gómez Fernández, Marisol ; Lecumberri Villamediana, Pablo ; Millor Muruzábal, Nora ; Rodríguez Mañas, Leocadio; García García, Francisco José; Izquierdo Redín, Mikel (BioMed Central, 2015)
Artículo / Artikulua
Background: Physical frailty has become the center of attention of basic, clinical and demographic research due to its incidence level and gravity of adverse outcomes with age. Frailty syndrome is estimated to affect 20 % ... -
Multichannel blind deconvolution of impulsive signals
Lecumberri Villamediana, Pablo; Gómez Fernández, Marisol ; Carlosena García, Alfonso (2005)
Contribución a congreso / Biltzarrerako ekarpena
In this communication, the problem of blind deconvolution of transient, impulsive signals in a multichannel environment is addressed. This kind of signals arise naturally, or are used as external excitation, in many ... -
Relevance of sex, age and gait kinematics when predicting fall-risk and mortality in older adults
Porta Cuéllar, Sonia; Martínez Ramírez, Alicia ; Millor Muruzábal, Nora ; Gómez Fernández, Marisol ; Izquierdo Redín, Mikel (Elsevier, 2020)
Artículo / Artikulua
Approximately one-third of elderly people fall each year with severe consequences, including death. The aim of this study was to identify the most relevant features to be considered to maximize the accuracy of a logistic ... -
Sources of linear and non-linear synchrony between brain and muscles: linear and non-linear CMC sources
Vidaurre, Carmen; Gómez Fernández, Marisol ; Nolte, Guido; Villringer, Arno; Carlowitz Ghori, Katherina von; Nikulin, Vadim V. (IEEE, 2020)
Contribución a congreso / Biltzarrerako ekarpena
This manuscript shows that it is possible to find distinct sources of brain activity, at similar frequencies, arising from linear and non-linear interactions of the brain with the muscular system. Those sources were obtained ... -
Valoración de la capacidad funcional en el ámbito domiciliario y en la clínica. Nuevas posibilidades de aplicación de la acelerometría para la valoración de la marcha, equilibrio y potencia muscular en personas mayores
Izquierdo Redín, Mikel; Martínez Ramírez, Alicia ; Larrión, J. L.; Irujo Espinosa, M.; Gómez Fernández, Marisol (Gobierno de Navarra, 2008)
Artículo / Artikulua
Dentro de cualquier población de individuos mayores de 65 años, una proporción sustancial (entre el 6% y el 25%) sufre diferentes síntomas del síndrome de fragilidad. A pesar de la complejidad del termino fragilidad y de ...
