Abstract
According to the Hallpike's technique, 30 normal individuals were examined, and the examinations were repeated at intervals of two days with 14 of them.
In order to decide the limit of physiological deviation in the calorigram thus obtained, we calculated the rejection limit of each value (Table 3).
As shown in the table, the width of limits is large, and so, even though canal paresis and directional preponderance are diagnosed by the combination of each value, some figures can be considered as the reverse relationship, i. e., the hypersensitivity of the other side against canal pasesis, and the hyposensitivity to the other side against directional preponderance.
Therefore, it is important to estimate the vestibular function not by the calorigram merely, but by the results of other examinations together with it.
From the results of repeated examinations, we could ascertain that there is no necessity to take the response decline into consideration, and that the results in this examination are reproducible.
