In this video, Dr. Kamran Barin, Ph.D., discusses advancements in measuring otolith function, an important but often underassessed component of the vestibular system. The ability to measure torsion during the ocular counter roll (OCR) test via videonystagmography (VNG) enables objective assessment of otolith function which mediates the static stage of the OCR.
Dr. Barin also explains how VNG can be used to assess otolith function using the dynamic subjective visual vertical (SVV) test.
