Official title
Voluntary Cough Airflow Dynamics and True Vocal Fold Kinematics in Persons With Reduced True Vocal Fold Mobility
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This project is a first attempt to assess cough airflow dynamics and true vocal fold (TVF) adduction and abduction angles during voluntary cough to examine the effects of changes in glottal closure due to reduced mobility of one true vocal fold. The hypothesis of this study is that the incomplete glottal closure due to reduced vocal fold mobility will result in changes in true vocal fold adductory and abductory angles during cough and will result in changes to voluntary cough airflow parameters. This study results will contribute to the existing knowledge of the laryngeal contribution to cough airflow dynamics.
