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).


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.


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.


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.
