Functional Exploration of Vestibulo-Ocular Reflex by a Caloric Stimulation

In this paper, we proposed the bidirectional mono-thermic test for the functional exploration of the vestibules by considering a temeprature variation in the semicirular canals constant for a short time and an inclination of the semicircular canal plan relative to the vertical. Through the proposed test we showed the evidence of an eventual asymmetry between the responses of right and left vestibules. In view of clinical practice, the proposed test has the advantages of saving the test time, of using only one temperature for the ear irrigation and of making only head movements to the given angle for the stimulation.
