Some patients who present with dyspnea, stridor, and airway obstruction have paradoxical vocal fold movement (pvfm), characterized by inappropriate adduction of the vocal folds during inspiration.

It has also been referred to as munchausen stridor, episodic laryngeal dyskinesia, psychosomatic stridor, and emotional laryngeal asthma. To date, little is known regarding the pathophysiology of pvfm. What is vocal cord dysfunction (vcd)?
