Expiratory (breathing-out) muscle strength and health outcomes in bronchiectasis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will measure expiratory muscle strength in adults with non‑cystic fibrosis bronchiectasis and relate those measurements to clinical outcomes including disease severity, history of hospital admissions, cough effectiveness, and quality of life. Participants aged 18–65 without an acute infection will undergo respiratory muscle testing and clinical data collection. The study is conducted at a single chest diseases center in Istanbul and will use the findings to explore whether expiratory muscle weakness contributes to impaired airway clearance. Results are intended to inform future interventional research in pulmonary rehabilitation and respiratory muscle training.
