Caloric reflex test - Wikipedia
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.
Caloric Testing - StatPearls - NCBI Bookshelf
2023年5月11日 · Caloric testing is a useful clinical tool to assess and quantify the functional status of individual vestibular systems. Caloric testing utilizes the vestibulo-ocular reflex (VOR) to identify a unilateral peripheral deficit. The VOR requires an intact functional brain stem.

2023年4月5日 · When a person is fully awake, the caloric reflex tests the tonic vestibular stimulation with its reflexive slow deviation of the eyes and the fast corrective saccadic movement initiated by the frontal eye field.
The caloric Test - Dizziness-and-Balance.com
2022年5月1日 · 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.
Caloric Test: A Deep Dive - Interacoustics
2023年10月27日 · It involves introducing a stimulus into an ear which either heats it up or cools it down, creating a temperature gradient. This generates an asymmetry between the two vestibular systems in the inner ears and causes a nystagmus to …
Interpretation and use of caloric testing - PMC
Caloric testing is an otoneurologic evaluation of the status of the vestibular-ocular reflex; it allows an evaluation of each labyrinth separately. The main aspects on the use and interpretation of caloric testing are reviewed. A systematic review ...
CALORIC TEST normal values - Dizziness-and-Balance.com
2021年2月21日 · The main value derived from caloric testing is the peak slow-phase velocity, for each side and each temperature (i.e. 4 values). Four numbers are obtained -- cold right, cold left, warm right, and warm left.
Caloric stimulation: MedlinePlus Medical Encyclopedia
2023年1月23日 · Caloric stimulation is a test that uses differences in temperature to diagnose damage to the acoustic nerve. This is the nerve that is involved in hearing and balance. The test also checks for damage to the brain stem. This test stimulates your acoustic nerve by delivering cold or warm water or air into your ear canal.
Caloric testing: background, technique, and interpretation
2010年1月1日 · Quantitative caloric testing is one of the most sensitive ways to detect loss of peripheral vestibular function and is the most widely used clinical test of the vestibulo-ocular reflex. The chief advantages of caloric testing is that the stimulus is easy to apply without requiring complex equipment and one can stimulate each labyrinth individually.
