    • Assessment of asymmetric leg loading before and after total hip arthroplasty using instrumented shoes 

      Martínez Ramírez, Alicia Upna; Weenk, Dirk; Lecumberri Villamediana, Pablo Upna; Verdonschot, Nico; Pakvis, Dean; Veltink, Peter H. (BioMed Central, 2014)   Artículo / Artikulua  OpenAccess
      Background: Total hip arthroplasty is a successful surgical treatment in patients with osteoarthritis of the hip. Different questionnaires are used by the clinicians to assess functional capacity and the patient's pain, ...
    • Computation of greatest common divisor for the blind deconvolution of transient impulsive signals 

      Lecumberri Villamediana, Pablo Upna; Gómez Fernández, Marisol Upna; Carlosena García, Alfonso Upna (Universitat Politècnica de Catalunya, 2005)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 Upna; López Martín, Antonio Upna; Massarotto, Marco Upna; Cruz Blas, Carlos Aristóteles de la Upna; Lecumberri Villamediana, Pablo Upna; Gómez Fernández, Marisol Upna; Pintor Borobia, Jesús María Upna; Gárriz Sanz, Sergio Upna (Universitat Politècnica de Catalunya, 2005)   Artículo / Artikulua  OpenAccess
      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.
    • 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 Upna; Lecumberri Villamediana, Pablo Upna; Gómez Fernández, Marisol Upna; Martínez Ramírez, Alicia Upna; Izquierdo Redín, Mikel Upna (BioMed Central, 2013)   Artículo / Artikulua  OpenAccess
      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 trunk kinematic parameters during walking 

      Martínez Ramírez, Alicia Upna; Martinikorena Aranburu, Ion Upna; Gómez Fernández, Marisol Upna; Lecumberri Villamediana, Pablo Upna; Millor Muruzábal, Nora Upna; Rodríguez Mañas, Leocadio; García García, Francisco José; Izquierdo Redín, Mikel Upna (BioMed Central, 2015)   Artículo / Artikulua  OpenAccess
      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 Upna; Gómez Fernández, Marisol Upna; Carlosena García, Alfonso Upna (2005)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 ...
    • Pre-operative ambulatory measurement of asymmetric lower limb loading during walking in total hip arthroplasty patients 

      Martínez Ramírez, Alicia Upna; Weenk, Dirk; Lecumberri Villamediana, Pablo Upna; Verdonschot, Nico; Pakvis, Dean; Veltink, Peter H. (BioMed Central, 2013)   Artículo / Artikulua  OpenAccess
      Background: Total hip arthroplasty is a successful surgical procedure to treat hip osteoarthritis. Clinicians use different questionnaires to assess the patient’s pain and functional capacity. Furthermore, they assess the ...
