Study Summary
Study investigators have completed a study testing laryngopharyngeal sensation at specific laryngopharyngeal subsites using a novel buckling force aesthesiometer in a series of 22 healthy adults at this institution. Investigators would like to use the same device apparatus to evaluate laryngopharyngeal sensation in patients with laryngopharyngeal disorders, such as adductor spasmodic dysphonia. This study will use a tested laryngopharyngeal aesthesiometer to examine laryngeal sensation using calibrated tactile stimuli to determine differences in somatotopic perceptual strength maps of laryngopharyngeal structures between patients with laryngopharyngeal disorders and healthy controls.
Primary Outcome
The outcome measure is the presence or absence of a laryngeal adductor reflex (LAR) which is the reflexive, involuntary closure of the vocal folds in response to stimulation, as seen on flexible laryngoscopy. This is a binary finding in that this is immediately observed as either being present or absent following direct contact by the tactile esthesiometer device. Accordingly, there are no units of measure. The presence or absence of the LAR was noted at the time of testing by the study team and
