title: [Spontaneous and provoked nystagmus in healthy subjects: on the so-called "vestibular" form].
abstract: A total of 25 healthy subjects were available for the study of provoked nystagmus using a series of vestibulometric functional tests affecting different component of the vestibular system. The study has demonstrates the high diagnostic value of provoked nystagmus and the importance of a series of vestibulometric functional tests as a tool for the evaluation of vestibular reactivity. Provoked nystagmus was documented in 3 cases using the full series of functional tests and was absent in 9 cases under the same conditions. It is concluded that observation of provoked nystagmus in individual tests reflects its etiology whereas its occurrence in the entire series of these tests suggests diagnosis of latent vestubular dysfunction.
