      Miguel Fernández, Jesús de; Rey Prieto, Marta; Salazar del Río, Miguel Antonio; López Matas, Helena; Guirao Cano, Lluís; Font Llagunes, Josep Maria; Lobo Prat, Joan (2023-08-09)
      Article
      Accés obert
      Studies on robotic interventions for gait rehabilitation after stroke require: (i) rigorous performance evidence; (ii) systematic procedures to tune the control parameters; and (iii) combination of control modes. In this ...

    • Design of a new actuation system for ABLE's lower limb robotic exoskeleton 

      Morey Olivé, Pau (Universitat Politècnica de Catalunya, 2021-06-21)
      Projecte Final de Màster Oficial
      Accés restringit per decisió de l'autor
      Realitzat a/amb:   ABLE Human Motion
      Lower-limb exoskeletons are an emerging technology to provide walking assistance to people who have a spinal cord injury. One of the key technical limitations of these devices is the actuators, wich tend to be bulky, heavy ...

    • Development and evaluation of a bowden cables-based actuation system for an ankle exoskeleton for people with stroke 

      Salvador Luna, Daniel (Universitat Politècnica de Catalunya, 2021-05-28)

      Accés restringit per decisió de l'autor
      Realitzat a/amb:   ABLE Human Motion
      Introduction: Ankle exoskeletons are emerging as a promising solution to accelerate post-stroke gait rehabilitation. One key element for the effectiveness of the exoskeleton is the weight distribution not to influence the ...

    • Firmware design of a portable medical device to measure the quadriceps muscle group after a total knee arthroplasty by EMG, LBIA and clinical score methods 

      Diez Clos, Arnau (Universitat Politècnica de Catalunya, 2022-07-04)
      Treball Final de Grau
      Accés obert
      El objetivo de este proyecto es el diseño del firmware de un dispositivo médico portátil para mediciones de EMG y LBIA, que se utilizará para la evaluación de pacientes de artroplastia total de rodilla, para estudiar ...

    • Influence of different CoCrMo counterfaces on wear in UHMWPE for artificial joints 

      González-Mora, V. A.; Hoffmann, Michael; Stroosnijder, R.; Espinar, Eduardo; Llamas, José María; Fernández-Fairén, Mariano; Gil Mur, Francisco Javier (Springer, 2011)
      Article
      Accés obert
      Wear tests were carried out to study the effect of various counterface materials in the wear behaviour of Ultra High Molecular Weight Polyethylene (UHMWPE). The materials used as counterfaces were based on varieties of ...

      AM technologies have been developed for different applications in sectors such as aeronautics, automotive, or healthcare. Additionally, the range of materials that can be 3D printed has increased considerably since these ...

    • Response of Saos-2 osteoblast-like cells to kilohertz-resonance excitation in porous metallic scaffolds 

      Deering, Joseph; Presas Batlló, Alexandre; Lee, Bryan E. J.; Valentín Ruiz, David (Elsevier, 2020-06-01)
      Article
      Accés obert
      Post-operative therapy for joint replacement is often performed to optimize bone volume and bone-implant contact. Methods, such as pulsed therapeutic ultrasound, have been shown to be a valuable addition to regular ...

    • The role of hardness and roughness on the wear of different CoCrMo counterfaces on UHMWPE for artificial joints 

      González-Mora, V. A.; Hoffmann, Michael; Stroosnijder, R.; Gil Mur, Francisco Javier (Springer, 2011)
      Article
      Accés obert
      Wear tests were carried out to study the effect of the hardness and roughness with various counterface materials on UHMWPE wear behaviour. The materials used as counterfaces were based on varieties of CoCrMo: 1) forged ...

    • Uni and multidirectional wear resistance of different crosslinking degrees in UHMWPE for artificial joints 

      González-Mora, V. A.; Hoffmann, Michael; Stroosnijder, R.; Espinar, Eduardo; Llamas, L. M.; Fernández-Fairén, Mariano; Gil Mur, Francisco Javier (Springer, 2011)
      Article
      Accés obert
      The aim of this work was to study the effect of UHMWPE crosslinking on wear performance. Differently treated UHMWPEs were studied by means of unidirectional and multidirectional wear tests. Unidirectional tests simulate ...
