Respiratory retraining therapy and management of laryngopharyngeal reflux in the treatment of patients with cough and paradoxical vocal fold movement disorder.
Annals of Otology, Rhinology, and Laryngology 2006 October
OBJECTIVES: We describe the outcome of patients with cough and paradoxical vocal fold movement disorder (PVFMD) treated with respiratory retraining therapy and management of laryngopharyngeal reflux (LPR).
METHODS: Twenty patients with the complaint of cough were given a diagnosis of PVFMD and treated with proton pump inhibitors for a minimum of 6 months followed by 3 to 5 sessions of respiratory retraining therapy. Pulmonary function testing (PFT) and subjective rating of cough and reflux (reflux symptom index; RSI) were performed. Also, PFT and rating of cough were performed on a group of 10 healthy volunteers with no complaint of cough.
RESULTS: The study group comprised 13 women and 7 men. The baseline cough rating and ratio of forced inspiratory volume at 0.5 second to forced inspiratory vital capacity (FIV0.5/FIVC) on PFT were significantly worse in the treatment group than in the control group. After therapy, 20 patients (100%) experienced improvement in cough, 19 patients (95%) experienced improvement on PFT, and 17 patients (85%) experienced improvement in the RSI score. The differences were statistically significant.
CONCLUSIONS: Respiratory retraining therapy combined with management of LPR is an effective treatment for patients with cough and PVFMD when a single-modality treatment is not sufficient.
