[The present status of vestibular testing (author's transl)].

Proceeding from the standard aims of every vestibular test, modern fine-quantitative investigatory methods with or without electronystagmographic recording in opposition to the systematic search for spontaneous and provoked nystagmus are presented with a view to their value for medical practice. Examination of spontaneous nystagmus and provoked nystagmus including the fistula symptom and coarse-quantitative excitability tests still represents the most important and most profitable part of the vestibular investigation. For modern research methods standardization of nomenclature and restriction of their plurality are as necessary as a method, which takes in not only single parameters but the whole data contents of vestibular reactions. The practicability of the method is documented by the author's own research work in this field.
