    Abstract Many survivors from severe coronavirus disease 2019 (COVID-19) suffer from persistent dyspnea and fatigue long after resolution of the active infection. In a cohort of 21 consecutive severe post-COVID-19 survivors admitted to an inpatient rehabilitation hospital, 16 (76%) of them had at least one sonographic abnormality of diaphragm muscle structure or function. This corresponded to a significant reduction in diaphragm muscle contractility as represented by thickening ratio (muscle thickness at maximal inspiration/end-expiration) for the post-COVID-19 compared to non-COVID-19 cohorts. These findings may shed new light on neuromuscular respiratory dysfunction as a contributor to prolonged functional impairments after hospitalization for post-COVID-19.

    Abstract Many survivors from acute respiratory distress syndrome (ARDS) associated with coronavirus disease 2019 (COVID-19) suffer from persistent dyspnea and fatigue long after resolution of the active infection. In a cohort of 25 consecutive COVID-19 ARDS survivors admitted to an inpatient rehabilitation hospital (76% male), 80% of them had at least one sonographic abnormality of diaphragm muscle structure or function. Specifically, when compared to established normative data, 76% had impaired contractility (reduced thickening ratio), and 20% patients had atrophy (reduced muscle thickness). These findings support neuromuscular respiratory dysfunction as a highly prevalent underlying cause for prolonged functional impairments after hospitalization for COVID-19.
