Abstract
We investigated normal response of bithermal caloric stimulation after repeated monothermal caloric stimulation. 12 subjects were selected for cold(30degreesC) water stimulation. 8 subjects were stimulated by warm(44degreesC) water. After the bithermal caloric test, caloric stimuli(cold or warm) was repeated 5 times on both ear with a 10 minute time interval and the next bithermal caloric test was performed. Monothermal caloric stimuli was done at the same temperature as the previous test a day later. The bithermal caloric test was repeated after 4 days. We checked the maximum slow phase eye velocity(SPEV) and calculated the canal paresis and directional preponderance. The SEPV was changed from 26.4(+/-10.9) degrees/sec to 26.7(+/-20.5) degrees/sec in repeated warm stimulation; from 25.0(+/-11.4) degrees/sec to 27.3(+/-11.1) degrees/sec in cold stimulation. Canal paresis was changed from 12.4(+/-8.7)% to 6.3(+/-5.1)% in repeated warm water stimulation; from 9.6(+/-9.9)% to 6.9(+/-3.1)% in cold stimuli. Directional preponderance was changed from 11.9(+/-6.9)% to 8.7(+/-9.9)% in warm stimuli; from 11.5(+/-7.6)% to 10.6(+/-5.5)% in cold stimuli. There was no significant change of caloric response after repeated monothermal caloric stimulation.
