The purpose of this study was to determine the effectiveness of the Buteyko Breathing Technique in lessening dyspnea in patients with one form of Paradoxical Vocal Fold Motion (PVFM), exertion-induced PVFM (EI-PVFM), concomitant with hyperventilation. The findings were post-treatment decreases in dyspnea severity, RTMV and HR, in addition to increases in ETCO2. There were also decreases in RTMV and dyspnea which remained after correction for alpha inflation. Therefore, the Buteyko Breathing Method could be useful for individuals with hyperventilation and EI-PVFM. Katz, D et al, 2019. Epub. Volume 35, Issue 1, pp. 40-51. Read the Study
