We introduce a dataset to provide insights into the relationship between the diaphragm surface electromyographic (sEMG) signal and the respiratory air flow. The data presented had been originally collected for a research project jointly developed by the Department of Information Engineering and the Department of Industrial Enginering and Mathematical Sciences, Polytechnic University of Marche, Ancona, Italy. This article describes data recorded from 8 subjects, and includes 8 air flow and 8 surface electromyographic (sEMG) signals for diaphragmatic respiratory activity monitoring, measured with a sampling frequency of 2 kHz.

Assessment of diaphragm function and fatigue typically relies on the measurement of transdiaphragmatic pressure (P). Although P serves as an index of diaphragm force output, it provides limited information regarding the ability of the muscle to shorten and generate power. We asked whether ultrasonography, combined with P, could be used to quantify changes in diaphragm function attributable to fatigue.

Background/aim: Chronic obstructive pulmonary disease (COPD) is often complicated by sarcopenia, a condition of reduced muscle mass and function that adversely affects quality of life, lung function, and exacerbation rates. Ultrasonography could be an effective tool for detecting sarcopenia, notably by assessing diaphragmatic function, which may indicate muscle health in COPD patients. This study aims to evaluate the effectiveness of diaphragmatic ultrasound in detecting sarcopenia among COPD patients.

A nulliparous woman in her late 30s with a history of pericardial patch repair for atrial septal defect and completed treatment for pulmonary tuberculosis 9 years ago presented with chest pain, breathlessness and abdominal pain. Radiological imaging revealed right-sided pneumothorax, pneumopericardium and pneumoperitoneum for which an intercostal drain (ICD) was placed. A contrast-enhanced CT of the abdomen showed a distal stomach perforation, which was managed conservatively.

This study analyzed the effects of an 8-week diaphragmatic core training program on postural stability during high-intensity squats and examined its efficacy in injury prevention and performance enhancement. Thirty-seven male participants were randomly assigned to three groups: diaphragmatic core training group (DCTG, n = 12), core training group (CTG, n = 13), and control group (CG, n = 12). Outcome measurements included diaphragm thickness, respiratory function (mean and maximal respiratory pressures), and squat postural stability (distance between the sacral and upper body center points, peak trunk extension moment, peak knee flexion moment, and dynamic postural stability index).

To explore the application value of surface respiratory muscle electromyography and its ratio to tidal volume in the assessment of airway hyperresponsiveness in bronchial asthma patients. A case-control study was conducted to retrospectively analyze the data of 29 asthma patients who visited the outpatient department of respiratory medicine of the First Affiliated Hospital of Guangzhou Medical University from October 2015 to May 2017 and 27 non-asthmatic subjects who were recruited as the control group.Changes in surface respiratory muscle electromyography (parasternal, EMG, diaphragmatic, EMG), and its ratio to tidal volume (EMG/VT, EMG/VT) before and after the histamine challenge test were compared between the asthma group and the control group; and their receiver operating characteristic (ROC) curves were plotted.
