    • EMG modeling 

      Rodríguez Falces, Javier Upna; Navallas Irujo, Javier Upna; Malanda Trigueros, Armando Upna (InTechOpen, 2012)   Capítulos de libro / Liburuen kapituluak  OpenAccess
      The aim of this chapter is to describe the approaches used for modelling electromyographic (EMG) signals as well as the principles of electrical conduction within the muscle. Sections are organized into a progressive, ...
    • Exact inter-discharge interval distribution of motor unit firing patterns with gamma model 

      Navallas Irujo, Javier Upna; Porta Cuéllar, Sonia Upna; Malanda Trigueros, Armando Upna (Springer, 2019)   Artículo / Artikulua  OpenAccess
      Inter-discharge interval distribution modeling of the motor unit firing pattern plays an important role in electromyographic decomposition and the statistical analysis of firing patterns. When modeling firing patterns ...
    • Independent component analysis as a tool to eliminate artifacts in EEG. A quantitative study 

      Iriarte, Jorge; Urrestarazu, Elena; Valencia Ustárroz, Miguel; Alegre, Manuel; Malanda Trigueros, Armando Upna; Viteri, César; Artieda, Julio (Lippincott, Williams & Wilkins, 2003)   Artículo / Artikulua  OpenAccess
      Independent component analysis (ICA) is a novel technique that calculates independent components from mixed signals. A hypothetical clinical application is to remove artifacts in EEG. The goal of this study was to apply ...
    • Métodos de procesamiento y análisis de señales electromiográficas 

      Gila Useros, Luis; Malanda Trigueros, Armando Upna; Rodríguez Carreño, Ignacio Upna; Rodríguez Falces, Javier Upna; Navallas Irujo, Javier Upna (Gobierno de Navarra, 2009)   Artículo / Artikulua  OpenAccess
      La electromiografía clínica es una metodología de registro y análisis de la actividad bioeléctrica del músculo esquelético orientada al diagnóstico de las enfermedades neuromusculares. Las posibilidades de aplicación y el ...
    • Modelling fibrillation potentials: analysis of time parameters in the muscle intracellular action potential 

      Rodríguez Falces, Javier Upna; Malanda Trigueros, Armando Upna; Gila Useros, Luis; Rodríguez Carreño, Ignacio Upna; Navallas Irujo, Javier Upna (IEEE, 2007)   Artículo / Artikulua  OpenAccess
      A single fibre action potential (SFAP) can be modelled as the convolution of a biolectrical source and a filter impulse response. In the Dimitrov-Dimitrova (D-D) convolutional model, the first temporal ...
    • Motor unit action potential duration, I: variability of manual and automatic measurements 

      Rodríguez Carreño, Ignacio Upna; Gila Useros, Luis; Malanda Trigueros, Armando Upna; García Gurtubay, Ignacio; Mallor Giménez, Fermín Upna; Gómez Elvira, Sagrario Upna; Rodríguez Falces, Javier Upna; Navallas Irujo, Javier Upna (Lippincott, Williams & Wilkins, 2007)   Artículo / Artikulua  OpenAccess
      To analyze the variability in manual measurements of motor unit action potential (MUAP) duration and to evaluate the effectiveness of well-known algorithms for automatic measurement. Two electromyographists carried out ...
    • Motor unit action potential duration, II: a new automatic measurement method based on the wavelet transform 

      Rodríguez Carreño, Ignacio Upna; Gila Useros, Luis; Malanda Trigueros, Armando Upna; García Gurtubay, Ignacio; Mallor Giménez, Fermín Upna; Gómez Elvira, Sagrario Upna; Rodríguez Falces, Javier Upna; Navallas Irujo, Javier Upna (Lippincott, Williams & Wilkins, 2007)   Artículo / Artikulua  OpenAccess
      To present and evaluate a new algorithm, based on the wavelet transform, for the automatic measurement of motor unit action potential (MUAP) duration. A total of 240 MUAPs were studied. The waveform of each MUAP was ...
    • A new muscle architecture model with non-uniform distribution of muscle fiber types 

      Navallas Irujo, Javier Upna; Malanda Trigueros, Armando Upna; Gila Useros, Luis; Rodríguez Falces, Javier Upna; Rodríguez Carreño, Ignacio Upna (World Academy of Science, Engineering and Technology, 2007)   Artículo / Artikulua  OpenAccess
      According to previous studies, some muscles present a non-homogeneous spatial distribution of its muscle fiber types and motor unit types. However, available muscle models only deal with muscles with homogeneous ...
