Computerized electronystagmography: normative data revisited

This study provides normative data from computerized electronystagmography (ENG) testing of 40 healthy subjects with an average age of 45 years. The clinical test protocol comprises an extensive vestibular examination with oculomotor, positional, rotary chair and caloric tests. The results show that with a computerized ENG set-up considerable variabilities df 22% for rotary chair asymmetry and 19% for caloric labyrinth asymmetry remain.
