Effects of Exercise-Based Pulmonary Rehabilitation in Patients with Long COVID: A Systematic Review and Meta-Analysis.

Background/

Objective

A substantial proportion of infected individuals develop persistent symptoms after the acute phase of COVID-19, regardless of initial disease severity. Long COVID (LC) remains a public health challenge characterized by impaired functional exercise capacity (FEC) and quality of life (QoL). We systematically synthesized evidence on the effects of in-person outpatient pulmonary rehabilitation (OPR) with individualized and supervised exercise in adults with LC.

Methods

Following PROSPERO (CRD42023389365), this study reviewed randomized controlled trials (RCTs) and observational cohort studies (OCSs) published between November 2019 and January 2026 in MEDLINE/PubMed, Web of Science, PEDro, and EMBASE.

Results

Fifteen studies (n = 803) were included. OPR improved FEC (6MWT; MD: 53.72 m, 95% CI 43.69-63.75) and 30″SST (MD: 4.68, 95% CI 3.59-5.77) and reduced exertional dyspnea. RCTs showed benefits in physical (MD: 8.04, 95% CI 3.02-13.05) and mental QoL (MD: 6.60, 95% CI 2.01-11.18) and dyspnea impact, with inconsistent PF findings. Fatigue showed a trend toward improvement but was measured using heterogeneous patient-reported tools in RCTs and OCSs.

Conclusions

Supervised PR improves FEC, QoL, and dyspnea in individuals with LC. In patients with fatigue/PEM, systematic assessment and continuous symptom monitoring are essential. High-quality controlled studies are needed to strengthen evidence and clinical guide.
