Analysis and applications of respiratory surface EMG: report of a round table meeting
(Springer, 2024-01-02)
Article
Open AccessSurface electromyography (sEMG) can be used to measure the electrical activity of the respiratory muscles. The possible applications of sEMG span from patients suffering from acute respiratory failure to patients receiving ... -
Assessment of the non-linear response of the fSampEn on simulated EMG signals
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessFixed sample entropy (fSampEn) is a promising technique for the analysis of respiratory electromyographic (EMG) signals. Its use has shown outperformance of amplitude-based estimators such as the root mean square (RMS) in ... -
Combining bioimpedance and myographic signals for the assessment of COPD during loaded breathing
(2021-01-01)
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. ... -
Differences in acoustic features of cough by pneumonia severity in patients with COVID-19: a cross-sectional study
(2023-05-01)
Article
Open AccessBackground Acute respiratory syndrome due to coronavirus 2 (SARS-CoV-2) is characterised by heterogeneous levels of disease severity. It is not necessarily apparent whether a patient will develop severe disease or not. ... -
Electromyography-based respiratory onset detection in COPD patients on non-invasive mechanical ventilation
(2019-03-07)
Article
Open AccessTo optimize long-term nocturnal non-invasive ventilation in patients with chronic obstructive pulmonary disease, surface diaphragm electromyography (EMGdi) might be helpful to detect patient-ventilator asynchrony. However, ... -
Evaluación no invasiva del impulso neural respiratorio y su relación con la respuesta mecánica mediante el análisis de señales electromiográficas de músculos respiratorios
(Universitat Politècnica de Catalunya, 2016-11-07)
Doctoral thesis
Open AccessRespiratory muscle contraction occurs in response to the electrical stimulation of the muscles. These electrical stimuli originate in the respiratory neurons of the brainstem, are transmitted via motor nerves to the ... -
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 ... -
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 ... -
Influence of the fuzzy function on the estimation of the fuzzy sample entropy with fixed tolerance values for the evaluation of surface EMG muscle activity
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference lecture
Open AccessFixed sample entropy (fSampEn) is a technique that has demonstrated superior performance to other amplitude estimators for assessing respiratory muscle electromyographic activity. This technique is based on the calculation ... -
Neural offset time evaluation in surface respiratory signals during controlled respiration
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyThe electrical activity of the diaphragm measured by surface electromyography (sEMGdi) provides indirect information on neural respiratory drive. Moreover, it allows evaluating the ventilatory pattern from the onset and ... -
Neural respiratory drive estimation in respiratory sEMG with cardiac arrhythmias
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessNeural respiratory drive as measured by the electromyography allows the study of the imbalance between the load on respiratory muscles and its capacity. Surface respiratory electromyography (sEMG) is a non-invasive tool ... -
Noninvasive assessment of inspiratory muscle neuromechanical coupling during inspiratory threshold loading
(Institute of Electrical and Electronics Engineers (IEEE), 2019-12-16)
Article
Open AccessDiaphragm neuromechanical coupling (NMC), which reflects the efficiency of conversion of neural activation to transdiaphragmatic pressure (Pdi), is increasingly recognized to be a useful clinical index of diaphragm function ... -
Noninvasive assessment of neuromechanical and neuroventilatory coupling in COPD
(2022-07)
Article
Open AccessThis study explored the use of parasternal second intercostal space and lower intercostal space surface electromyogram (sEMG) and surface mechanomyogram (sMMG) recordings (sEMG para and sMMG para , and sEMG lic and sMMG ... -
Noninvasive assessment of neuromechanical coupling and mechanical efficiency of parasternal intercostal muscle during inspiratory threshold loading
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-03-04)
Article
Open AccessThis study aims to investigate noninvasive indices of neuromechanical coupling (NMC) and mechanical efficiency (MEff) of parasternal intercostal muscles. Gold standard assessment of diaphragm NMC requires using invasive ... -
Performance evaluation of fixed sample entropy in myographic signals for inspiratory muscle activity estimation
(2019-02-01)
Article
Open AccessFixed sample entropy (fSampEn) has been successfully applied to myographic signals for inspiratory muscle activity estimation, attenuating interference from cardiac activity. However, several values have been suggested for ...
