Thinning and dysfunction of the diaphragm muscle observed during mechanical ventilation complicate the extubation process and increase the risk of respiratory failure in patients. Diaphragm dysfunction prolongs ventilator use and increases ICU mortality. The main objective of this research is to determine whether respiratory physiotherapy has protective or ameliorative effects on diaphragm muscle structure and function, to optimize the ventilator weaning process, and to provide scientific contributions to the field of respiratory rehabilitation. Changes in diaphragm thickness will be objectively evaluated using ultrasonography, and the aim is to obtain evidence-based data on the effectiveness of respiratory physiotherapy.",[24],"Diaphragm Dysfunction","RECRUITING","2026-05-07",{"date":28,"type":29},"2026-05-08","ACTUAL",{"date":31,"type":29},"2025-08-01",{"date":33,"type":20},"2026-10-01",{"name":35,"class":36},"Hitit University","OTHER",1,{"id":39,"slug":40,"hasResults":11,"nctId":41,"briefTitle":42,"officialTitle":43,"acronym":4,"eligibilityCriteria":44,"healthyVolunteers":11,"sex":16,"minAge":45,"maxAge":46,"enrollmentInfo":47,"targetDuration":4,"studyType":49,"phases":50,"briefSummary":52,"conditions":53,"keywords":4,"overallStatus":55,"whyStopped":4,"lastUpdateSubmitDate":56,"lastUpdatePostDateStruct":57,"startDateStruct":59,"completionDateStruct":61,"leadSponsor":63,"locationsCount":4},"100634460","effect-of-inspiratory-muscle-training-on-diaphragm-function-in-copd-patients-100634460","NCT07539974","Effect of Inspiratory Muscle Training on Diaphragm Function in COPD Patients","Effect of Threshold Inspiratory Muscle Training on Diaphragm Thickness and Diaphragm Excursion Value in Chronic Obstructive Pulmonary Disease Patients","Inclusion Criteria:\n\n* Patients with a COPD GOLD stage 2\n* Age 40-59 years\n* Maximal Inspiratory Pressure (MIP) value of less than 70 cmH₂O or below the lower limit of normal for their age and gender\n* Clinically stable for at least 4 weeks prior to the study\n* Ready to participate in research and sign informed consent\n\nExclusion Criteria:\n\n* Patients with contraindications to Inspiratory Muscle Training or spirometry (e.g., recent thoracic or abdominal surgery, pneumothorax, or history of spontaneous pneumothorax).\n* Patients participating in other structured respiratory muscle training or pulmonary rehabilitation programs concurrently that could confound the results\n* Patients undergoing other therapies that may affect diaphragmatic muscle measurement results, such as electrical diaphragmatic stimulation","40 Years","59 Years",{"count":48,"type":20},15,"INTERVENTIONAL",[51],"NA","This study investigates the effect of threshold inspiratory muscle training on diaphragm thickness and diaphragm excursion, measured using ultrasonography, in patients with stable chronic obstructive pulmonary disease (COPD).",[54,24],"Chronic Obstructive Pulmonary Disease (COPD)","NOT_YET_RECRUITING","2026-04-20",{"date":58,"type":29},"2026-04-23",{"date":60,"type":20},"2026-04-01",{"date":62,"type":20},"2026-09-01",{"name":64,"class":36},"Universitas Padjadjaran",{"id":66,"slug":67,"hasResults":11,"nctId":68,"briefTitle":69,"officialTitle":69,"acronym":70,"eligibilityCriteria":71,"healthyVolunteers":72,"sex":16,"minAge":17,"maxAge":73,"enrollmentInfo":74,"targetDuration":4,"studyType":21,"phases":4,"briefSummary":76,"conditions":77,"keywords":80,"overallStatus":55,"whyStopped":4,"lastUpdateSubmitDate":85,"lastUpdatePostDateStruct":86,"startDateStruct":88,"completionDateStruct":90,"leadSponsor":92,"locationsCount":37},"100612430","correlation-of-diaphragm-shear-wave-elastography-with-transdiaphragmatic-pressure-in-healthy-adults-a-feasibility-study-100612430","NCT07253480","Correlation of Diaphragm Shear-Wave Elastography With Transdiaphragmatic Pressure in Healthy Adults: a Feasibility Study","PLEASSURE 1","Inclusion Criteria:\n\n* 18-60 years, BMI 18-30 kg\u002Fm²\n* No known respiratory, neuromuscular, or cardiothoracic disease\n* Able to perform inspiratory maneuvers and consent.\n\nExclusion Criteria:\n\n* Pregnancy\n* History of smoking (\\> 10 pack years)\n* Impaired swallowing, as well as esophageal diseases, or disorders at the level of the gastroesophageal sphincter",true,"60 Years",{"count":75,"type":20},12,"Changes in intrapleural pressure after lung volume reduction in Chronic Obstructive Pulmonary disease (COPD) patients can lead to complications, including an increased risk of pneumothorax. This procedure, intended to improve lung function, may disturb the pressure balance within the pleural space, potentially precipitating pneumothorax. Careful monitoring of intrapleural pressure could help predict patients at risk. However, intrapleural pressure can currently only be measured invasively. Diaphragm shear-wave elastography (SWE) has been shown to reflect transdiaphragmatic pressure during isovolumetric inspiratory efforts and ventilation against inspiratory loading, and therefore may serve as a non-invasive surrogate for intrapleural pressure. This project outlines a stepwise study plan to evaluate SWE as a tool for intrapleural pressure monitoring (Figure 1). The project only moves to the next phase is the study previous phase was achieved successfully. The current protocol involves the first phase: to validate diaphragm SWE against transdiaphragmatic pressure and assess measurement reliability for local ultrasound systems in healthy adults.This prospective, single-centre, observational validation study will include twelve healthy adult volunteers. During a single study session, participants will perform standardized inspiratory efforts while simultaneous measurements of diaphragm SWE, transdiaphragmatic pressure (via esophageal and gastric balloon catheters), and mouth pressures are obtained. These methods are routinely applied in physiological research and carry minimal risk. Apart from brief nasal or throat discomfort during catheter placement, no significant adverse effects are expected. By establishing the relationship between diaphragm SWE, transdiaphragmatic pressure, and mouth pressures, this study aims to provide the essential validation step for future clinical research in COPD patients following lung volume reduction.",[78,24,79],"Diaphragm Ultrasound","Health Adult Subjects",[81,82,83,84],"diaphragm","ultrasound","diaphragmatic pressure","shear-wave elastography","2025-11-29",{"date":87,"type":29},"2025-12-05",{"date":89,"type":20},"2026-04",{"date":91,"type":20},"2026-09",{"name":93,"class":36},"Isala",{"id":95,"slug":96,"hasResults":11,"nctId":97,"briefTitle":98,"officialTitle":98,"acronym":99,"eligibilityCriteria":100,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":101,"targetDuration":4,"studyType":21,"phases":4,"briefSummary":103,"conditions":104,"keywords":105,"overallStatus":25,"whyStopped":4,"lastUpdateSubmitDate":109,"lastUpdatePostDateStruct":110,"startDateStruct":112,"completionDateStruct":114,"leadSponsor":116,"locationsCount":37},"100548438","incidence-and-impact-of-icu-acquired-diaphragm-weakness-100548438","NCT06420999","Incidence and Impact of ICU-acquired Diaphragm Weakness","PRODIGY","Inclusion Criteria:\n\n1.

Among the complications of ICU stay, diaphragmatic dysfunction is common, with a prevalence of 60 to 80%, and is associated with increased mortality and prolonged hospital stays.
