Study Summary

Paradoxical Vocal Fold Motion (PVFM) is a condition where vocal cords adduct (move toward another) instead of abduct (move away from one another) during inspiration, thus causing shortness of breath. The goal of this pilot randomized controlled trial is to compare the efficacy of biofeedback as compared to laryngeal control therapy (LCT) in the treatment of PVFM. Participants will take surveys about their symptoms and their expectations of treatment prior to initiating treatment and after completion of their assigned treatment. Researchers will compare the biofeedback group to the LCT group to see if participants have differences in changes of their symptoms.

Primary Outcome

This is a 10-item questionnaire with scores that range from 0-40, with 40 representing the greatest possible severity of symptoms. The DI is a clinical assessment tool that was designed and validated specifically for patients with upper airway obstruction, including patients with PVFM. The primary outcome measure will be the difference between the two groups in the change in Dyspnea Index (DI).

Interventions

  • BEHAVIORAL Biofeedback
  • BEHAVIORAL Laryngeal control therapy (LCT)
