Veterans experiencing dizziness and/or balance problems are
assessed in the Vestibular/Balance Laboratory. The
Vestibular/Balance Laboratory is located in Rooms L072, L073, and
L074 of the Audiology Clinic in the Outpatient Building #204. The
Vestibular/Balance laboratory is equipped with the ICS computerized
CHARTR video nystagmography/electronystagmograpjy (VNG/ENG) system
and a water and an air caloric stimulator. VNG/ ENG is the test of
choice for determining site and laterality of vestibular disorders.
A System 2000 rotational chair (Micromedical Technologies) is
available to determine if dizziness may be due to a disorder of the
inner ear or brain and to identify bilateral vestibular loss. The
micro-centrifuge and subjective visual vertical options to the
rotational chair are available to assess otolithic organ function.
Vestibular evoked myogenic potentials are also used to assess
otolithic (saccule) function.
Other vestibular tests in the Laboratory include the Dynamic
Visual Acuity Test and the VORTEQ test (Micromedical Technologies).
A computerized dynamic posturography (CDP) system and Long
Forceplate attachment (NeuroCom, Smart Equitest) is located in the
laboratory and available for balance assessment and balance
re-training. The CDP test assesses major sensory and motor
components of balance. The laboratory also contains an infra-red
video eye movement recorder ( Eye Dynamics ) for use with
assessment and treatment of patients with benign paroxysmal
positioning vertigo (BPPV. Faith Akin, Ph.D. is director of the
