[Vocal cord dysfunction in athletes: Interest of rehabilitation to effort].

Vocal Cord Dysfunction (VCD) is a syndrome characterized by paradoxical adduction of the vocal folds during breathing. Its non-specific clinical manifestations frequently lead to misdiagnosis and delay in its treatment. The treatment of VCD is not pharmacological but rehabilitative and remains poorly appreciated. In this clinical case we describe a 16-year-old female judoka who presented with effort intolerance associated with occasional dyspnea, which had suddenly worsened over the preceding few months so that in now produced sudden respiratory difficulty, mainly during intense and sudden efforts. After a period where her symptoms were confused with asthma, she was diagnosed with exercise-induced VCD. Her treatment was aimed to: (a) rehabilitate respiratory mechanics in order to eliminate abdominal-thoracic asynchrony, (b) rehabilitate naso-nasal breathing, (c) train her to control abdominal-diaphragmatic breathing at rest and then during effort, (d) train her to use ventilatory control as soon as prodromal symptoms appear in order to prevent the development of stridor or complete closure of the vocal folds (at rest and then progressively during exercise). Following the implementation of these rehabilitation strategies to correct her ventilatory and dyskinetic issues, the patient no longer develops respiratory discomfort during exercise, including during judo competitions.
