Patients with symptoms of dizziness, vertigo and/or other balance problems when referred to an Audiology Service for evaluation can be tested using traditional VNG/ENG, rotary chair or posturography equipment. If an audiologist does not have access to this equipment in the clinic, there are tests that can be performed to assess a patient’s symptoms. In this session, we will discuss and demonstrate several “low-tech” procedures, such as dynamic visual acuity, tests of postural stability and other measures, which can help to differentiate among central disorders, peripheral vestibular disorders of unilateral or bilateral origin and non-vestibular disorders. These procedures are not designed to replace the quantitative results from laboratory studies obtained using equipment such as those listed above, rather they can be used, in conjunction with a comprehensive case history, to provide an initial impression of the potential pathology within the balance system, help to initiate necessary referrals as well as estimate the compensation status of the patient.
