Vestibular function testing plays a critical role in understanding balance
disorders. These tests augment a well-performed history and physical exam in
providing quantitative information regarding vestibular reflexes, central
oculomotor function and postural control strategies. Video-oculography (VOG) and
caloric stimulation play a major role in evaluation of both peripheral vestibular
and central oculomotor disorders. Rotational chair testing and, more recently the
Dynamic Visual Acuity Test (DVAT) and Gaze Stabilization Test (GST) provide
information regarding higher frequency vestibulo-ocular reflex (VOR) function.
Computerized Dynamic Posturography (CDP) explores the interaction of the
vestibular, visual and proprioceptive systems for posture control. Finally, the
cervical Vestibular Evoked Myogenic Potential (cVEMP) test and the Dynamic
Subjective Visual Vertical (DSVV) test provide information regarding saccular and
utricular function, respectively. New techniques and applications continue to
provide knowledge both of disease processes and potential medical, surgical and
rehabilitative interventions.
