- Exercise-induced paradoxical vocal fold motion (PVFM) leads to acute dyspnea during exertion.
- 5 weeks of respiratory muscle training (RMT) increased respiratory muscle strength and reduced dyspnea in a soccer player with PVFM.
- The effects of RMT were maintained over a 5 week withdrawal period.
RMT effectively improves cough and swallowing function in people with dysphagia.
The variables measured during the study include:
All of the above were assessed before and after five weeks of IMT, and then again after a five week withdrawal phase, in an individual soccer player with PVFM.
IMT resulted in increased MIP and decreased dyspnea ratings across both treatment phases (IMT treatment and withdrawal phases). No change in MIP or dyspnea ratings occurred in response to treatment withdrawal. Transnasal flexible laryngoscopy, after strenuous exercise and during rapid breathing and phonation tasks, revealed normal laryngeal findings.
IMT improves increased respiratory strength and reduced dyspnea, and may be a promising treatment approach for athletes with exercise-induced PVFM.
