    • Adaptive control for wearable robots in human-centered rehabilitation tasks 

      Rajasekaran, Vijaykumar (Universitat Politècnica de Catalunya, 2015-12-22)
      Doctoral thesis
      Open Access
      Robotic rehabilitation therapies have been improving by providing the needed assistance to the patient, in a human-centered environment, and also helping the therapist to choose the necessary procedure. This thesis presents ...

    • Adaptive walking assistance based on human-orthosis interaction 

      Rajasekaran, Vijaykumar; Aranda López, Juan; Casals Gelpí, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Conference report
      Open Access
      An assistive rehabilitation strategy for a lower-limb wearable robot is proposed and evaluated. The control strategy monitors the human-orthosis interaction torques and modifies the orthosis operation mode depending on its ...

    • An adaptive control strategy for postural stability using a wearable robot 

      Rajasekaran, Vijaykumar; Aranda López, Juan; Casals Gelpí, Alicia; Pons, Jose Luis (2015-11)
      Article
      Open Access
      Wearable robots are expected to expand the use of robotics in rehabilitation since they can widen the assistance application context. An important aspect of a rehabilitation therapy, in terms of lower extremity assistance, ...

    • Compliant gait assistance triggered by user intention 

      Rajasekaran, Vijaykumar; Aranda López, Juan; Casals Gelpí, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Conference report
      Open Access
      An automatic gait initialization strategy based on user intention sensing in the context of rehabilitation with a lower-limb wearable robot is proposed and evaluated. The proposed strategy involves monitoring the human-orthosis ...

    • Control of an ambulatory exoskeleton with a brain–machine interface for spinal cord injury gait rehabilitation 

      López Larraz, Eduardo; Trincado Alonso, Fernando; Rajasekaran, Vijaykumar; Pérez Nombela, Soraya; Ama, Antonio J. del; Aranda López, Juan; Minguez, Javier; Gil Agudo, Angel; Montesano Del Campo, Luis (2016-08-03)
      Article
      Open Access
      The closed-loop control of rehabilitative technologies by neural commands has shown a great potential to improve motor recovery in patients suffering from paralysis. Brain–machine interfaces (BMI) can be used as a natural ...

    • Event-based control for sit-to-stand transition using a wearable exoskeleton 

      Rajasekaran, Vijaykumar; Vinagre Ruiz, Manuel; Aranda López, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Open Access
      Sit-to-stand transition is an essential step in a lower limb rehabilitation therapy, mainly for assisting the patient to transit from wheel chair to the next level of therapy. A mixed stiffness-damping control adaptation ...

    • Recovering planned trajectories in robotic rehabilitation therapies under the effect of disturbances 

      Rajasekaran, Vijaykumar; Aranda López, Juan; Casals Gelpí, Alicia (2014-09)
      Article
      Restricted access - publisher's policy
      Robotic rehabilitation is an emerging technology in the field of Neurorehabilitation, which aims to achieve an effective patient recovery. This research focusses on the control strategy for an assistive exoskeleton aiming ...

    • User intention driven adaptive gait assistance using a wearable exoskeleton 

      Rajasekaran, Vijaykumar; Aranda López, Juan; Casals Gelpí, Alicia (Springer, 2016)
      Article
      Open Access
      A user intention based rehabilitation strategy for a lower-limb wearable robot is proposed and evaluated. The control strategy, which involves monitoring the human-orthosis interaction torques, determines the gait initiation ...

    • Volition-adaptive control for gait training using wearable exoskeleton: preliminary tests with incomplete spinal cord injury individuals 

      Rajasekaran, Vijaykumar; López Larraz, Eduardo; Trincado Alonso, Fernando; Aranda López, Juan; Montesano Del Campo, Luis; Ama, Antonio J. del; Pons Rovira, Jose Luis (2018-01-03)
      Article
      Open Access
      Background Gait training for individuals with neurological disorders is challenging in providing the suitable assistance and more adaptive behaviour towards user needs. The user specific adaptation can be defined based on ...
