Web003429. In medicine, the caloric reflex test (sometimes termed 'vestibular caloric stimulation ') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal. This method was developed by Robert Bárány, who won a Nobel prize in 1914 for this discovery.

The caloric test is a part of the ENG. It is an attempt to discover the degree to which the vestibular system is responsive and also how symmetric the responses are, between left and right ears. It is a test of the lateral semicircular canals alone -- it does not assess vertical canal function or otolithic function.
