Physiotherapist check for breathing pattern problems
Official title: An Evaluation of Physiotherapy Assessment; A Mixed Methods Study to Evaluate the Physiotherapy Assessment of Breathing Pattern Disorder
Run by Royal Brompton & Harefield NHS Foundation Trust · NCT07543588 · Data updated 2026-11-12
This project will test whether a physiotherapist checklist called the BPAT can spot breathing pattern disorder and track changes after physiotherapy in people with breathlessness, asthma, or healthy volunteers.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 referred for unexplained breathlessness or suspected BPD, including those with primary BPD or BPD alongside asthma, who can attend outpatient physiotherapy sessions are the ideal candidates.
✕Probably not a fit
People with major respiratory or cardiac diseases (COPD, ILD, bronchiectasis, cystic fibrosis, structural heart disease), pregnant individuals, those unable to consent, or people already in pulmonary/cardiac rehabilitation or receiving specialist ENT therapy are excluded and unlikely to benefit.

What this trial studies
This observational project will test the measurement properties and clinical usefulness of the Breathing Pattern Assessment Tool (BPAT), a physiotherapist-completed checklist for identifying breathing pattern disorder (BPD). Adults with primary BPD, people with asthma, and healthy controls will be recruited at Royal Brompton Hospital (approximately 100 BPD, 25 asthma, 25 healthy). At the initial visit two physiotherapists will independently complete BPAT scores, and BPD patients will have a repeat assessment roughly 4 weeks later around routine physiotherapy treatment to measure change. BPAT scores will be compared with established breathlessness and breathing-symptom questionnaires to examine agreement, inter-rater reliability, and responsiveness over time.
Why it matters
Potential benefit: If successful, BPAT could give clinicians a simple, reliable way to identify BPD and monitor improvement after physiotherapy, helping tailor treatment and track progress.
How similar studies have gone: Some clinician-rated tools for dysfunctional breathing have shown promise in small studies, but robust validation of BPAT against patient-reported measures and inter-rater reliability remains limited, making this partly novel.
