Influence of Habituation and Alertness on the Simple Cold Caloric Test

Abstract

The influences of habituation and alertness on the simple cold caloric test (20°C,20 sec,5 ml) were examined. With double stimuli, the habituation greatly affected the number of beats, duration and maximum slow phase velocity. As to differences in alertness (between arithmetic and conversation), changes in slow phase velocity were observed in patients with CP (canal paresis).
In the simple cold caloric test, the absolute value of the maximum slow phase velocity is usedtherefore, the influence of habituation and alertness should be considered.
