What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Summary

This study evaluates the Breathing Pattern Assessment Tool (BPAT), a checklist used by physiotherapists to diagnose breathing pattern disorder—a condition where breathing is inefficient, causing breathlessness. Researchers will compare BPAT scores with patient questionnaires and track changes after treatment. The study includes 150 adults with breathing pattern disorder, asthma, or healthy volunteers.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Breathing Pattern Assessment Tool (BPAT)
What this could lead to
If successful, this could provide a reliable tool for diagnosing and monitoring breathing pattern disorder, helping guide physiotherapy treatment.
What could go wrong
This is an early-stage observational study, not a treatment trial. The tool may not prove accurate or useful in routine practice.
