Interstitial lung diseases cause scarring and stiffness of the lungs, leading to impaired breathing and reduced quality of life. The diaphragm, the main respiratory muscle, may become weakened in these patients. Pulmonary rehabilitation is a comprehensive program that includes exercise, education, and support to improve physical capacity and overall well-being.
This study will evaluate whether an eight-week pulmonary rehabilitation program improves the diaphragmatic index (measured by ultrasound), quality of life, exercise tolerance (through functional tests), muscle strength, and dyspnea perception in patients with interstitial lung diseases.
Participants will be recruited at the Antiguo Hospital Civil de Guadalajara "Fray Antonio Alcalde" between July and December 2025. The findings will provide new insights into the impact of pulmonary rehabilitation on diaphragmatic function and contribute scientific evidence to optimize the treatment of these conditions.
Age ≥ 18 years.
Confirmed diagnosis of interstitial lung disease (ILD) by pulmonology and imaging criteria.
Clinically stable for at least 4 weeks prior to enrollment (no exacerbations or hospitalizations).
Able to perform pulmonary rehabilitation and functional tests safely, as determined by medical evaluation.
Acute exacerbation of ILD or respiratory infection within the last 4 weeks.
Severe comorbidities limiting participation (e.g., unstable cardiac disease, uncontrolled hypertension, recent myocardial infarction < 3 months).
Advanced neuromuscular disease or musculoskeletal limitation that prevents exercise training.
Cognitive impairment or psychiatric condition interfering with protocol adherence.
