Treatment of Paradoxical Vocal Fold Motion Disorder (PVFMD) With a Form of Respiratory Retraining Technique

"Patients serve as their own controls. During a three week baseline, participants will complete the Dyspnea Index (DI), and have their heart rate, Resp. minute volume and ETCO2 on days 1 and 21 (or on the day treatment commences). Participants will complete a daily log reporting their daily symptoms. This will serve as the baseline prephase.~Post 1 phase will include five individual therapy sessions teaching the respiratory retraining techniques over an estimated three week period.~Post2 phase will comprise of a six week home practice phase. There will be four measuring points per participant: pre1/pre2 measurements on day 1 and 21 (or on the day therapy begins), post1 upon completing five therapy sessions and post 2 upon completion of the home practice phase."
