Breathing battle: biofeedback vs. retraining for vocal cord trouble
NCT ID NCT05770518
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two non-drug treatments for paradoxical vocal fold motion (PVFM), a condition where vocal cords close when they should open, causing shortness of breath. Fifty-one adults were randomly assigned to either biofeedback (watching their breathing on a screen) or laryngeal control therapy (learning relaxation and breathing techniques). Researchers measured symptom changes using a breathing difficulty questionnaire to see which approach works better.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
biofeedback and laryngeal control therapy
What this could lead to
If this works, it could point toward a more effective, non-drug treatment for breathing difficulties caused by vocal cord dysfunction.
What could go wrong
This is a small pilot study with only 51 participants, so results may not apply to everyone. The treatments are behavioral and may not work for all patients.
