Detection of sleep-disordered breathing in patients with spinal cord injury using a smartphone
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-29)
Article
Open AccessPatients with spinal cord injury (SCI) have an increased risk of sleep-disordered breathing (SDB), which can lead to serious comorbidities and impact patients’ recovery and quality of life. However, sleep tests are rarely ... -
Global and transient effects of intermittent hypoxia on heart rate variability markers: evaluation using an obstructive sleep apnea model
(Institute of Electrical and Electronics Engineers (IEEE), 2021-01-01)
Article
Open AccessIntermittent hypoxia (IH) produces autonomic dysfunction that promotes the development of arrhythmia and hypertension in patients with obstructive sleep apnea (OSA). This paper investigated different heart rate variability ... -
Enhanced monitoring of sleep position in sleep apnea patients: smartphone triaxial accelerometry compared with video-validated position from polysomnography
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-05-26)
Article
Open AccessPoor sleep quality is a risk factor for multiple mental, cardiovascular, and cerebrovascular diseases. Certain sleep positions or excessive position changes can be related to some diseases and poor sleep quality. Nevertheless, ... -
SleepPos app: an automated smartphone application for angle based high resolution sleep position monitoring and treatment
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-01)
Article
Open AccessPoor sleep quality or disturbed sleep is associated with multiple health conditions. Sleep position affects the severity and occurrence of these complications, and positional therapy is one of the less invasive treatments ... -
Quantitative evaluation of trunk function and the StartReact effect during reaching in patients with cervical and thoracic spinal cord injury
(2021-08-18)
Article
Open AccessObjective. Impaired trunk stability is frequent in spinal cord injury (SCI), but there is a lack of quantitative measures for assessing trunk function. Our objectives were to: (a) evaluate trunk muscle activity and movement ... -
Evaluation of respiratory muscle activity by means of concentric ring electrodes
(2021-03)
Article
Open AccessSurface electromyography (sEMG) can be used for the evaluation of respiratory muscle activity. Recording sEMG involves the use of surface electrodes in a bipolar configuration. However, electrocardiographic (ECG) interference ... -
Assessment of trunk flexion in arm reaching tasks with electromyography and smartphone accelerometry in healthy human subjects
(Nature, 2021-03-08)
Article
Open AccessTrunk stability is essential to maintain upright posture and support functional movements. In this study, we aimed to characterize the muscle activity and movement patterns of trunk flexion during an arm reaching task in ... -
Health outcomes from home hospitalization: multisource predictive modeling
(JMIR, 2020-10-07)
Article
Open AccessBackground: Home hospitalization is widely accepted as a cost-effective alternative to conventional hospitalization for selected patients. A recent analysis of the home hospitalization and early discharge (HH/ED) program ... -
Combining bioimpedance and myographic signals for the assessment of COPD during loaded breathing
(2020-05-27)
Article
Open AccessChronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic conditions. The current assessment of COPD requires a maximal maneuver during a spirometry test to quantify airflow limitations of patients. ... -
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 ... -
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 ... -
Evaluation of a wearable device to determine cardiorespiratory parameters from surface diaphragm electromyography
(2019)
Article
Open AccessUsing wearable devices in clinical routines could reduce healthcare costs and improve the quality of assessment in patients with chronic respiratory diseases. The purpose of this study is to evaluate the capability of a ...
