The purpose of Vaneysa Hansen’s research study is to determine the effect of specific respiratory muscle training on speech intelligibility, vocal intensity, maximal respiratory pressures, lung volume and communication success in 5 patients with Parkinson’s. Subjects will train on a device for 10 weeks in an ABAB within-subject withdrawal design study.
