dc.description.abstractThe semicircular canals are involved in the coding of angular acceleration of the head and body. Presently, video-nystagmography (VNG) and specifically, caloric testing, is the gold standard for evaluation of semicircular canal function. Caloric irrigation via VNG can only evaluate horizontal semicircular canal function; with this test, there is no way to evaluate the function of the anterior and posterior vertical semicircular canals. The video Head Impulse Test (vHIT) is a relatively new protocol that has the capability to test the function of the horizontal, anterior vertical, and posterior vertical semicircular canals. Because the vHIT system is newly available to clinicians, there is a need to collect normative data, particularly for the vertical semicircular canals. For this study, data was collected from 12 participants with no complaint or history of balance difficulty. Additionally, we compared our data with normative data collected in an earlier study to determine consistency. Lateral average velocity gain measurements were consistent however, a comparison of RALP an LARP velocity gain measurements showed inconsistency.
