In this video, Dr. Kamran Barin, Ph.D. discusses advancements in measuring otolith function, an important but often under assessed component of the vestibular system. The new option of measuring torsion during the ocular counter roll test via VNG offers the ability to objectively assess the otolith function which mediates the static stage of the ocular counter roll. Dr. Barin explains how VNG can also be used to assess otolith function using the dynamic subjective visual vertical test.
