DISORDERS OF BALANCE AND EQUILIBRIUM AND VESTIBULAR REHABILITATION - NEU 913 is arguably what many learners describe as our single most important course. The human vestibular system is a complex and fascinating system that regulates so very much of our nervous system function. A comprehensive review of the anatomy and physiology of the vestibular system both centrally and peripherally will be performed. Evaluation of the system is emphasized and provocative testing is emphasized as is canalith repositioning therapy. An complex overview of extraocular motility and optokinetics will be included as is an introduction to videonystagmography and caloric testing.
