Respiratory Muscle Function After Hospitalisation for COVID-19 -Pathophysiological Model on Severity, Determinants and Clinical Consequences of Respiratory Muscle Strength Impairment in Patients Who Had Been Hospitalised for COVID-19-

RWTH Aachen University·observational·Posted Apr 22, 2021·Updated Jan 28, 2026

In Brief

An observational study evaluating Comprehensive assessment of respiratory muscle function. for Covid19 and Diaphragm Injury. Completed, enrolled 50 participants across 1 site.

Detailed Summary

Fatigue and exercise intolerance after survived COVID-19-infection might be related to weakness of the respiratory muscles especially following invasive mechanical ventilation in the Intensive Care Unit. The aim of the project is to measure respiratory muscle function and strength in our respiratory physiology laboratory (Respiratory Physiology Laboratory, Department of Pneumology and Intensive Care Medicine, Head: Professor Michael Dreher) in patients who survived a severe COVID-19-infection (25 with a severe course requiring mechanical ventilation in the intensive care unit, 25 with a moderate-severe course requiring administration of supplemental oxygen only, respectively). Based on this data the aim is to develop a model which determines the severity, pathophysiology and clinical consequences of respiratory muscle dysfunction in patients who had been hospitalised for COVID-19. This will potentially prove the importance of a dedicated pulmonologic rehabilitation with respiratory muscle strength training in patients who had been hospitalised for COVID-19.

Interventions

Comprehensive assessment of respiratory muscle function.other

Comprehensive assessment of respiratory muscle function to the point of its invasive assessment with recordings of twitch transdiaphragmatic pressure in response to magnetic phrenic nerve stimulation and stimulation of the lower thoracic nerve roots.
