Analysis of Smartphone Triaxial Accelerometry for Monitoring Sleep-Disordered Breathing and Sleep Position at Home
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04-13)
Article
Open AccessObstructive sleep apnea (OSA) is a sleep disorder in which repetitive upper airway obstructive events occur during sleep. These events can induce hypoxia, which is a risk factor for multiple cardiovascular and cerebrovascular ... -
Automatic event detector from smartphone accelerometry: Pilot mHealth study for obstructive sleep apnea monitoring at home
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessObstructive sleep apnea (OSA) is a common disorder with a low diagnosis ratio, leaving many patients undiagnosed and untreated. In the last decades, accelerometry has been found to be a feasible solution to obtain respiratory ... -
Automatic silence events detector from smartphone audio signals: a pilot mHealth system for sleep apnea monitoring at home
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessObstructive sleep apnea (OSA) is a prevalent disease, but most patients remain undiagnosed and untreated. Recently, mHealth tools are being proposed to screen OSA patients at home. In this work, we analyzed full-night audio ... -
Entropy analysis of acoustic signals recorded with a smartphone for detecting apneas and hypopneas: A comparison with a commercial system for home sleep apnea diagnosis
(Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
Article
Open AccessObstructive sleep apnea (OSA) is a prevalent disease, but most patients remain undiagnosed and untreated. Here we propose analyzing smartphone audio signals for screening OSA patients at home. Our objectives were to: (1) ... -
Identifying muscle synergies from reaching and grasping movements in rats
(Institute of Electrical and Electronics Engineers (IEEE), 2020-01-01)
Article
Open AccessReaching and grasping (R&G) is a skilled voluntary movement which is critical for animals. In this work, we aim to identify muscle synergy patterns from R&G movements in rats and show how these patterns can be used to ... -
Onset detection to study muscle activity in reaching and grasping movements in rats
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessEMG signals reflect the neuromuscular activation patterns related to the execution of a certain movement or task. In this work, we focus on reaching and grasping (R&G) movements in rats. Our objective is to develop an ... -
Study of time-frequency characteristics of single snores: extracting new information for sleep apnea diagnosis
(Editorial Universitat Politècnica de València, 2016)
Conference report
Open AccessObs tructive sleep apnea (OSA) is a highly prevalent chronic disease, especially in elderly and obese population . Despite constitut ing a huge health and economic problem, most patients remain undiagnosed due to limitations ...
