The Callier Comprehensive Assessment of Balance (CAB) includes seven tests that can evaluate patients for issues related to the vestibular system. Sometimes we’ll detect a small tumor on the acoustic nerve or the vestibular nerve,” she said. The Callier CAB includes tests of the eyes, hearing, reflexes, blood pressure, balance and dizziness. Last year, more than 100 people were evaluated at Callier for dizziness and balance issues. Gohmert and clinical audiologist Dr. Jason Baker oversee the testing, which occurs at Callier’s Dallas campus, and audiology students gain experience by learning about balance issues.
