Vestibular function laboratories utilize a multitude of diagnostic instruments to
evaluate a dizzy patient. Caloric irrigators, oculomotor stimuli, and rotational chairs
produce a stimulus whose accuracy is required for the patient response to be accurate.
Careful attention to everything from cleanliness of equipment to threshold adjustments
determine on a daily basis if patient data are going to be correct and useful. Instrumentation
specifications that change with time such as speed and temperature must periodically
be checked using calibrated instruments.
