Impact of COVID-19 on Exercise-Based Pulmonary Rehabilitation: What Lessons Have We Learned?

The Coronavirus Disease 2019 (COVID-19) pandemic had a major global impact on health care, including the delivery, modality, and importance of outcomes in pulmonary rehabilitation (PR). This review discusses the impact of the pandemic on PR and the changes that were required to maintain its delivery. This article reviews the current evidence on PR during the COVID-19 pandemic period, focusing on delivery models, modalities, outcomes, perspectives, and barriers. A search of the MEDLINE, Embase, and SciELO databases and the Cochrane Library on this topic was conducted between December 1, 2019 and August 1, 2023. Studies were reviewed and relevant topics were included in this narrative. Rehabilitation of patients with severe acute COVID-19 and symptoms of long COVID has been challenging. The number of rehabilitation programs worldwide is still low, and community-based programs are still rare. Integrated programs with a multidisciplinary approach and exercise therapy with individualized prescription based on symptoms have been an interesting strategy. Telerehabilitation and outpatient rehabilitation are both effective in the treatment of patients with chronic obstructive pulmonary disease. However, the uptake of PR remains considerably low, and technological barriers for patients and lack of technological resources in low-income countries affect the delivery of these services in much of the world.
