Breathing disorder that is frequently mistaken for asthma.
Accurate diagnosis is made by a multi-disciplinary team, which can include a speech language pathologist, a primary care physician, an asthma/allergy specialist, a pulmonologist, a psychologist, a psychiatrist, a sports medicine specialist, an athletic trainer, and a gastroenterologist.
Diagnosis is established through the case history, laryngeal visualisation, and pulmonary function studies.
Behavioural therapy by a speech language pathologist is the standard treatment.
Paradoxical vocal fold motion (PVFM), also called paradoxical vocal cord dysfunction, is a breathing disorder characterised by approximation rather than abduction/opening of the vocal folds during inspiration. This can result in upper-airway obstruction and stridor.      Diagnosis is most often based upon exclusion of other differentials.
