Inspiratory pressure threshold training in a case of congenital bilateral abductor vocal fold paralysis.

We present a non-surgical treatment option to decrease symptoms of dyspnea in a 6 year-old child with congenital bilateral abductor vocal fold paralysis. A respiratory muscle strength-training program was used to strengthen her inspiratory muscles for 8 months, 3 to 5 days per week. Inspiratory muscle strength increased over the course of training, resulting in reported decreases in dyspnea by both the child and parents during speech and exercise.
