The minimal ice water caloric test compared with established vestibular caloric test procedures
Journal of Vestibular Research, 2005Caloric testing of the vestibular labyrinth is usually performed by classical caloric test procedures (CCTP) using water warmed to 30°C and 44°C. Ice water irrigation (4°C) is usually not performed, although it might be useful as a bedside test. To verify the validity of the Minimal Ice Water Caloric Test (MIWCT), comparative video-oculographic ...

A Simple Quantitative Caloric Test
Archives of Otolaryngology - Head and Neck Surgery, 1958In a recent article, Hitschler 2 described a simple caloric test in which he used water at a constant temperature (36-37 F) for a definite period of time (5 seconds). He stated that the time during which the water is in contact with the eardrum is the important factor, not the amount of water, and that severe reactions are uncommon in this procedure ...

The electronystagmograms on 400 sequential patients who completed bithermal caloric tests were examined. It was found that taking +/- 25 per cent as the limit for bithermal caloric testing and +/- 15 per cent for monothermal hot caloric testing, the hot caloric screen detected almost all patients who gave abnormal bithermal caloric test results without

Screening methods for caloric testing
Clinical Otolaryngology, 1987In order to evaluate the screening capacity and the reliability of monothermal caloric stimulation, the caloric results obtained in 272 patients have been reviewed. The results of a complete bithermal 4-test-set are compared with the results of the hot and cold stimulation considered separately.

Air caloric test: Irrigation technique
The Laryngoscope, 1977AbstractThe technique of using air to perform the caloric test is discussed. Greater temperature differences and larger volumes of air are needed to achieve stimulations equal to those caused by water irrigations. Special consideration must be given to the design and operation of air irrigation equipment.

Charles Hallpike decided that greater precision could be obtained with the caloric test by measurement of one or more attributes of the responses to some suitably graded stimulus. He chose to measure the duration of induced nystagmus. Hallpike chose water at 30°C and 44°C (7°C below and above body temperature, respectively) and allowed it to flow for ...

Simplification of Clinical Caloric Test
Archives of Otolaryngology - Head and Neck Surgery, 1965THE FACT that thermic stimuli, when applied to the external auditory canal, could induce labyrinthine nystagmus was known by Brown-Sequard3as early as 1860, and Bornhardt2was the first to apply this knowledge experimentally by inducing caloric stimulation of the semicircular canals of pigeons.

Caloric Tests on Platform: “Paradoxical Responsiveness”
Acta Oto-Laryngologica, 1995This paper deals with the abnormal responsiveness of the paradoxical stabilizing type (SR) occurring after caloric tests (CALT) performed on a passive force platform. The normal response after CALT (cold/warm, monaurally performed) consists of transient ataxia and body sway towards the side of the nystagmic slow phase induced by a similar CALT ...

Caloric testing with small temperature gradients. Caloric zero.
ORL; journal for oto-rhino-laryngology and its related specialties, 1984Caloric nystagmus was investigated in 50 normal subjects with stimulation of the temperatures 30, 33, 35, 39, 41, and 44 degrees C. Mean values of the duration and the eye speed of the slow phase of adjacent temperatures were significantly different. No difference could be demonstrated between the equidistant temperatures 30/44 and 35/41 degrees C, but
