Abstract: Our vocal folds are essential for us to communicate. Voice disorders severely impair communication and reduce quality of life. A major contributor to voice disorders is vocal hyperfunction. The first focus of this research is the biological consequences of vocal hyperfunction. Second, this work will expand the definition of vocal hyperfunction to include reflex cough. This work resulted in the identification of a commonly encountered volatile chemical stimulus to elicit cough. Objective cough outcome measures were used to evaluate the effects of respiratory retraining intervention on reflex cough in healthy adults. This area of research merges the multifaceted functions of the larynx to better understand the factors contributing to vocal hyperfunction.
