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

Laryngeal Structure and Function in the Pediatric Larynx

“…Case presentation. In a previous study, we used a unique respiratory strength training program to help a female adolescent with bilateral abductor paralysis deal with her sensation of breathlessness, or shortness of breath (Baker, Sapienza, Davenport, Martin, Hoffman, & Woodson, 2003). Voice quality was hoarse and of lower than normal loudness, but was self-reported as functional.…”

Inspiratory muscle strength training with behavioral therapy in a case of a rower with presumed exercise-induced paradoxical vocal-fold dysfunction

“…An inspiratory pressure-threshold training program was recommended for this patient to increase the strength of his inspiratory muscles. This recommendation was based on previous research in our laboratory at the University of Florida with two adult patients and one pediatric case presenting with breathlessness during exercise and speech resulting from upper airway limitation [15][16][17][18][19]. All patients previously treated by IMST were able to strengthen inspiratory muscles with the threshold-training program and reported decreased dyspnea during exercise and speech.…”

Inspiratory Muscle Training in Exercise-Induced Paradoxical Vocal Fold Motion

“…[20][21][22][23][24][25][26][29][30][31][32] In a review of the research literature, a joint committee of the American College of Chest Physicians and the American Association of Cardiovascular and Pulmonary Rehabilitation (ACCP/AACVPR) 20 determined that there is sufficient evidence to support VMT as a component of pulmonary rehabilitation for COPD patients: "Selected randomized, controlled trials that included adequate training loads (i.e., an intensity of at least 30% of maximum inspiratory pressure) and measured clinical outcomes have shown improvements in dyspnea and/or exercise tolerance with VMT." Specific inspiratory muscle training (IMT), which involves resistive breathing maneuvers, likewise improved inspiratory muscle strength and endurance and stabilized vital capacity in patients with neuromuscular disorders.…”

“…29 Similarly, IMT involving inspiratory pressure threshold breathing maneuvers resulted in increased inspiratory muscle strength and decreased dyspnea during exercise and speech in a patient with decreased glottal area 30 and in two patients with bilateral abductor vocal fold paralysis. 31,32 The value of IMT also has been demonstrated in persons without known respiratory system impairment. Specific IMT resulted in significant increases in measures of inspiratory muscle strength in healthy, sedentary adults.…”
