DIAPHRAGM INJURY

This study looked at whether 6 weeks of special breathing exercises (inspiratory muscle training) can improve diaphragm strength and reduce shortness of breath in 18 COVID-19 survivors who still had trouble breathing. Participants had proven diaphragm weakness and no other explan…

This study looks at how breathing machines (mechanical ventilators) might injure the diaphragm, the main muscle used for breathing. Researchers will monitor 50 ICU patients over their first 7 days on the ventilator, measuring diaphragm activity and function. The goal is to unders…

This study investigates whether a specific ultrasound measurement—called maximal diaphragm thickening fraction—can accurately assess diaphragm function in patients who are on mechanical ventilation. Researchers will compare this ultrasound technique to a standard method (phrenic …

This completed study looked at 25 people who had COVID-19 but were not hospitalized, yet still felt short of breath and tired. Researchers measured their diaphragm strength using advanced breathing tests and ultrasound. The goal was to see if diaphragm weakness is a hidden cause …

This completed study looked at breathing muscle function in 50 people who were hospitalized for COVID-19. Half had been on a ventilator, half only needed extra oxygen. Researchers used advanced tests to measure diaphragm strength and movement. The goal was to understand why many …
