[Cumulometry with fast components of nystagmus (author's transl)].

The cumulogram of slow nystagmus phases has proved as a useful method for the analysis of vestibular nystagmus. However, its computation depends on the availability of special apparatuses. Therefore, the relations are studied between the cumulogram of slow phases and the cumulogram of fast phases that can be determined more easily. The analysis of 57 pendular tests shows the close correlation (r = 0,98) of the respective values for vestibular gain. Considering the statistical connection the comparison of these two methods and their results, resp., is well practicable.
