First Advanced Vestibular Rehabilitation Course

Therapists and audiologists from around the United States participated in the first Advanced VRT Course at AIB.  AIB has been providing VRT courses since 1994.  This course is designed for those furthering their education in vestibular rehabilitation.  Topics included advanced VRT protocols to improve treatment outcomes for vestibular disorders. Additional topics included: pediatrics, psychological and psychiatric aspects of dizziness, and advanced BPPV treatment protocols.  This two day worshop also allowed break-out sessions for demonstrations and hands-on learning with Dr. Gans. If you are interested in learning more about our courses in vestibular rehabilitation and assessment, please visit the AIB Education Foundation website for a complete listing of workshops!

Comparison of Horizontal and Vertical Dynamic Visual Acuity in Patients with Vestibular Dysfunction and Nonvestibular Dizziness

J Am Acad Audiol. 2007 Mar;18(3):236-44. Comparison of horizontal and vertical dynamic visual acuity in patients with vestibular dysfunction and nonvestibular dizziness. Roberts RA, Gans RE. The American Institute of Balance, 8200 Bryan Dairy Road, Suite 340, Largo, FL 33777, USA. Blurred vision with head movement is a common symptom reported by patients with vestibular dysfunction affecting the vestibulo-ocular reflex (VOR). Impaired VOR can be measured by comparing visual acuity in which there is no head movement to visual acuity obtained with head movement. A previous study demonstrated that dynamic visual acuity (DVA) testing using vertical head movement revealed deficits in impaired VOR. There is evidence that horizontal head movement is more sensitive to impaired VOR. The objective of this Read More

Computerized dynamic visual acuity with volitional head movement in patients with vestibular dysfunction

Ann Otol Rhinol Laryngol. 2006 Sep;115(9):658-66. Computerized dynamic visual acuity with volitional head movement in patients with vestibular dysfunction. Roberts RA, Gans RE, Johnson EL, Chisolm TH. The American Institute of Balance, 8200 Bryan Dairy Road, Suite 340, Largo, FL 33777, USA. OBJECTIVES: Patients with uncompensated vestibular dysfunction frequently report blurred vision during head movement, a symptom termed oscillopsia. One way to measure the functional deficit associated with an impaired vestibulo-ocular reflex is by comparing visual acuity from a baseline condition in which there is no head movement to visual acuity obtained during a dynamic condition with head movement. A previously described test incorporated a treadmill upon which patients walked during assessment of visual acuity. The objective of the current Read More
