Background:
Data examining the role of pulmonary rehabilitation (PR) in interstitial lung disease (ILD) are limited. We tested the hypothesis that PR can improve functional status and dyspnea in a large group of patients with ILD, and that certain baseline patient variables can predict this improvement.
Methods:
Data from patients who were referred to PR with a diagnosis of ILD were included. Baseline and post-PR variables were recorded, and changes in 6-min walk test (6MWT) distance and dyspnea were evaluated. The impact of baseline variables on change in 6MWT distance and dyspnea were analyzed.
Results:
A statistically significant difference was seen in both the change in Borg score and 6MWT distance after PR (p < 0.0001). These changes were consistent with previously established clinically significant differences. Baseline 6MWT distance was a significant predictor of change in 6MWT distance (p < 0.0001), with increasing baseline 6MWT distance predicting a smaller improvement after PR.
Conclusions:
These results suggest that PR should be considered as a standard of care for patients with ILD.

Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
