Exercise Induced Laryngeal Obstruction (EILO)/Paradoxical Vocal Fold Motion (PVFM)

Paradoxical Vocal Fold Motion or Exercise Induced Laryngeal Obstruction has been described as a breathing disorder frequently mistaken for asthma. Behavioral treatment by a speech-language pathologist is the gold standard after all other potential causes have been ruled out. It is a breathing disorder defined by closing of the vocal folds during inspiration, which can result a feeling of throat tightness and noise on inhalation, chronic coughing or throat clearing. PVFM has been frequently mistaken for asthma which has led to unnecessary medical care from medication to hospitalization.  Cause has been proposed to be secondary to irritable larynx syndrome or hyperactive/hypersensitivity in the laryngeal airway.
