A double closed loop to enhance the quality of life of Parkinson's disease patients: REMPARK system
(IOS Press, 2014)
Conference lecture
Open AccessThis paper presents REMPARK system, a novel approach to deal with Parkinson's Disease (PD). REMPARK system comprises two closed loops of actuation onto PD. The first loop consists in a wearable system that, based on a ... -
Advanced manufacturing of ceramics for biomedical applications: Subjection methods for biocompatible materials
(Universidad de Zaragoza (UZA), 2013)
Conference report
Restricted access - publisher's policyThe continuously growing utilization of ceramic compounds in the field of medicine, industry and aerospace, among others, imply a high degree of specialization in terms of the material properties and functionalization due ... -
A friction model for non-singular complementarity formulations for multibody systems with contacts
(American Society of Mechanical Engineers (ASME), 2017)
Conference report
Restricted access - publisher's policyThe dynamics of multibody systems with many contacts are frequently formulated as a Linear Complementarity Problem (LCP), for which several direct or iterative algorithms are available to solve it efficiently. These ... -
Ageing is associated with deterioration of calcium homeostasis in isolated human right atrial myocytes
(2015-02-24)
Article
Open AccessAgeing-related cardiac disorders such as heart failure and atrial fibrillation often present with intracellular calcium homeostasis dysfunction. However, knowledge of the intrinsic effects of ageing on cellular calcium ... -
A “HOLTER” for Parkinson's disease: validation of the ability to detect on-off states using the REMPARK system
(2018-01-01)
Article
Open AccessThe treatment of Parkinson's disease (PD) with levodopa is very effective. However, over time, motor complications (MCs) appear, restricting the patient from leading a normal life. One of the most disabling MCs is ON-OFF ... -
Algorithms for B wave detection
(Universitat Politècnica de Catalunya, 2013-04-09)
Master thesis (pre-Bologna period)
Open Access
Covenantee: Rheinisch-Westfälische Technische Hochschule Aachen[ANGLÈS] The objective of this Master Thesis was to develop algorithms for B waves detection in ICP. This goal was approached by two different methods that depend basically in the resolution of the acquired ICP. Then, both ... -

A real-time method for decoding the neural drive to muscles using single-channel intra-muscular EMG recordings
(2017-09-01)
Article
Open AccessThe neural command from motor neurons to muscles — sometimes referred to as the neural drive to muscle — can be identified by decomposition of electromyographic (EMG) signals. This approach can be used for inferring the ... -
