Likely a good fit

Ideal candidates are patients reporting persistent respiratory problems with specific scores on the mMRC or Nijmegen scales.

Probably not a fit

Patients unable to perform the required measurements due to cognitive or physical impairments may not benefit from this study.

What this trial studies

This observational study aims to explore the signs and symptoms of dysfunctional breathing in patients suffering from post COVID-19 condition. It will utilize various measurements and questionnaires to identify and assess dysfunctional breathing, focusing on the underlying mechanisms and patient experiences. The study is part of a larger project, ReCOV, which takes a holistic approach to understanding the consequences of COVID-19. Participants will be recruited from the ReCov cohort and evaluated for their physical and psychological recovery over time.

Why it matters

Potential benefit: If successful, this study could lead to improved assessment and management strategies for patients experiencing dysfunctional breathing after COVID-19.

How similar studies have gone: While this approach is part of a larger multi-disciplinary project, similar studies have shown promise in understanding post-viral syndromes, though this specific focus on dysfunctional breathing is relatively novel.
