For the clinician who wants to examine patients complaining about some form of dizziness or vertigo, the vestibular examination proper is only part of what he needs. Otological, medical, and audiological examinations are equally as important if not more so.
In most instances, vestibular examination can be done very well without nystagmography. Nevertheless, nystagmography can be indispensable in many other cases.
Various forms of dysrhythmia and other deviations may be present without proving any disease.
Two new provocative tests, hyperventilation and Valsalva maneuver, seem to indicate disease of the peripheral vestibular system by altering the nystagmus pattern.
