The overall goal of this T2 translational research project is to pilot an interdisciplinary high-intensity group singing program to improve speech and swallowing in patients with Parkinson's Disease (PD) and to explore the impact of this program on quality of life (QOL). This research has three specific aims: 1) Determine the effects of a high-intensity group vocal training program on vocal function and laryngeal structure; 2) Determine the transference of vocal training to laryngeal aspects of swallowing; 3) Determine the effect of patient-reported changes in Quality of Life (QOL) as the result of participation in a group vocal training program.
