[The frequency-calorigram an analogous representation of the caloric nystagmus reaction].

A new diagram is proposed for the analogous representation of the vestibular reactions to carloric stimulation (calorigram). It provides a centripetal scale for both ears with exchangeable parameters. The response is given by pointers representing both the intensity and direction of the nystagmus. The arrangement facilitates the visual recognition of typical vestibular disorders, and allows the synoptical comparison of follow up-tests. Its usefulness was proved by the application in 1100 caloric examinations, in which the maximal postcaloric frequency of the nystagmus was evaluated from the ENG and recorded in the frequency calorigram.
