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.
