Year in Review: Long COVID and Pulmonary Rehabilitation

There have been an estimated 100 million people diagnosed with COVID-19 in the United States, with a majority of patients reporting persistent symptoms expressed as long COVID. The 2 most frequently reported long COVID symptoms are shortness of breath and fatigue. Exercise training during pulmonary rehabilitation (PR) is a successful strategy for improving the lives of people with persistent respiratory symptoms caused by a variety of lung diseases. This narrative review assessed the impact of exercise interventions on functional exercise capacity measures and related symptoms (dyspnea, fatigue) in people with long COVID over the last year. Articles were accessed through electronic databases including PubMed, Embase, CINAHL Plus with full text (EBSCO), and LitCovid. Findings for this Year in Review revealed that exercise interventions and PR show promise for improving functional exercise capacity, dyspnea, and fatigue in people with long COVID. This review supports the need for more rigorous scientific studies on the benefits of structured PR in people with long COVID who have respiratory-related symptoms.
