The effects of pulmonary rehabilitation on lung function and functional capacity of individuals who recovered from COVID-19 were analyzed systematically. A randomized clinical trial and three case series that compared lung function and functional capacity of individuals who contracted COVID-19 before and after undergoing pulmonary rehabilitation programs were included in this review. The bias analysis of the randomized clinical trial was performed using the Rob tool from Cochrane, while the analysis of the case series was performed using the Checklist for case series – Critical Appraisal tools for use in JBI Systematic Reviews. Of the 6,868 abstracts selected, 45 full-text articles were reviewed and only four met the inclusion criteria. In conclusion, both lung function and functional capacity of individuals cured of COVID-19 after undergoing a pulmonary rehabilitation program showed significant improvement.
