This age-old age test is a crude test of the balance system but is still used by some clinicians to get a very gross idea of the functioning of the vestibular labyrinths which are the organs of balance situated deep inside the ear. The vestibular labyrinths are a small part of the balance system and disorders of the vestibular labyrinth are one of the many causes of giddiness. Though one of the commonest tests advised for evaluation of vestibular / balance function, yet it is a very incomplete and un-physiological test of balance function. In spite of this being an out dated test, yet we retain the arrangements for the traditional caloric tests as many clinicians specifically request for this test even now.
