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.

Patients with Coronavirus disease 2019 (COVID-19) who require invasive mechanical ventilation frequently meet the acute respiratory distress syndrome (ARDS) diagnostic criteria. Hospitals based in the United States have been incorporating prone positioning (PP) into the COVID-19-related ARDS treatment plan at a higher rate than normal. Here, we describe 11 patients admitted to a single inpatient rehabilitation hospital who were subsequently diagnosed with acquired focal/multifocal peripheral nerve injury (PNI) in association with the use of PP for COVID-19-related ARDS. The reason for the high rate of PNI associated with PP in COVID-19 ARDS is likely multifactorial, but may include an underlying state of hyperinflammation and hypercoagulability already linked to other the neurological sequelae of COVID-19. Physicians must be aware of this elevated susceptibility to PNI in severe COVID-19 and refined standard PP protocols in order to reduce the risk.

Because more patients with advanced heart failure are receiving a left ventricular assist device (LVAD) as destination therapy or a bridge to transplantation, there is increasing attention on functional outcomes and quality of life after LVAD implantation. Rehabilitation providers in the acute inpatient rehabilitation setting increasingly will treat patients with an LVAD and should understand the exercise physiology, medical management, rehabilitation considerations, and outcomes after rehabilitation for patients with an LVAD. The purpose of this article is to provide the physiatrist with a comprehensive understanding of the rehabilitation of patients with advanced heart failure and LVAD implantation. Changes in relevant organ system physiology and exercise physiology after LVAD are summarized. Safety of rehabilitation and program considerations for acute inpatient rehabilitation are reviewed. Recommendations for medical management and prevention of secondary complications seen in patients with an LVAD are outlined. A discussion of outcomes after acute inpatient rehabilitation, the dual diagnosis of stroke and LVAD placement, and long-term cognitive, functional, and quality-of-life outcomes after LVAD placement is presented.

Patients with LVADs demonstrate functional gains in inpatient rehabilitation. However, there is a high incidence of complications in this population, which often requires transfer to an acute care setting.
