Technique in electronystagmography
The Journal of Laryngology & Otology, 1979AbstractPitfalls in the interpretation of electronystagmographic traces may be avoided by the reduction of artefacts in recording. These artefacts are often the result of poor physical conditions and lack of patient cooperation during recording. This paper examines technique in the clinical practice of eletronystagmography and suggests methods of ...

Electronystagmography in the Laboratory Rat
Acta Oto-Laryngologica, 1979A method is described for obtaining electronystagmograms from the awake laboratory rat. Threshold valves for rotation impulse and oscillatory acceleration were determined, as well as the time constant for the horizontal semicircular canal. The time constant appeared to be small.

Three Derivations in Electronystagmography
Acta Oto-Laryngologica, 1969In order to be able to detect in the simplest possible manner and in part also to analyse the changed direction of nystagmus, three derivations for recording nystagmus have been introduced. Three bipolar leads are connected to three electrodes. The magnitude of the electric effect in one derivation is directly proportional to the corneoretinal ...

Electronystagmography on Normal Persons
Acta Oto-Laryngologica, 1974Twenty normal persons were studied by elec-tronystagmography (ENG) for spontaneous, positional, and caloric nystagmus. In addition, a pendulum test was performed. Spontaneous nystagmus was demonstrated in 3 persons. Another 6 had positional nystagmus in 1-4 positions, with a maximum angular velocity of 7.5/scc.

Electronystagmography and horizontal directionalization
The Journal of Laryngology & Otology, 1984A series of 22 patients complaining of disorders of equilibrium or hearing thought to be due to Central Nervous System (CNS) dysfunction has been studied. Data were obtained for electronystagmography (ENG), horizontal directionalization (HD), the staggered spondee word test (SSW), brainstem auditory evoked responses (BSER) and the Chocholle test of ...

Graphic records of the movements of the eyes in nystagmus can be obtained by means of the electrocardiograph. The records, like the electrocardiogram, are based on the fact that a muscle under the influence of a stimulus, including a nerve impulse, is traversed by a wave of negativity, the so-called action current, immediately preceding its contraction.

Electronystagmography in Neurological Diagnosis
Stereotactic and Functional Neurosurgery, 1979Electronystagmography (ENG) is a technique for recording nystagmus and other eye movements; our technique, based on the utilization of a bioelectrical potential which exists between the retina and the cornea, has been reported in detail elsewhere in a monograph [29].
