Biofeedback vs Laryngeal Control Therapy in Management of Paradoxical Vocal Fold Motion (BLiMP)
In Brief
A clinical study evaluating Biofeedback and Laryngeal control therapy (LCT) for Paradoxical Vocal Fold Motion and Vocal Cord Dysfunction. Completed, enrolled 51 participants across 1 site.
Detailed 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.

Timeline
Interventions
Biofeedback is a strategy used in the treatment of PVFM, which involves allowing patients to directly visualize their breathing patterns during laryngoscopy.
This treatment typically involves 2 guided therapy sessions that include patient education, relaxation techniques, and training in specific breathing techniques.
