In this video Dr. Michelle Petrak Ph.D. discusses the benefits of performing functional assessments of the vestibular ocular reflex, such as computerized dynamic visual acuity. Functional assessments support clinicians in developing individualized rehabilitation programs where the baseline can be objectively set and progress can be objectively measured. Dr. Petrak also presents a multi canal BPPV case study and explores how 3D head modelling and the use of repositioning chairs can improve diagnostic accuracy.
