Summary

This trial compares two treatments for people with Paradoxical Vocal Fold Motion (PVFM), a condition causing shortness of breath. One treatment uses video feedback to help patients see and improve their breathing, while the other involves working with a therapist to control vocal cords. The goal is to see which method is more effective in reducing symptoms.

Who is the study for?
This trial is for adults over 18 with Paradoxical Vocal Fold Motion, experiencing significant breathing difficulty during inhalation. They must have a specific score indicating abnormal breathlessness and be referred to the Washington University School of Medicine Voice and Airway Center. Those who've had laryngeal surgery, other vocal cord issues, can't speak English, or had recent COVID-related symptoms are excluded.
What is being tested?
The study compares biofeedback therapy against Laryngeal Control Therapy (LCT) in treating PVFM. Participants will receive one of these treatments randomly and complete surveys about their symptoms before and after treatment to assess changes.
What are the potential side effects?
Since this trial involves non-invasive therapies focusing on breathing techniques and feedback mechanisms rather than drugs or surgeries, side effects may include discomfort from unfamiliar exercises or frustration if improvements aren't immediate.
