Electronystagmography in the Office

Archives of Otolaryngology - Head and Neck Surgery, 1968
THE USE of electronystagmography (ENG) offers promise as a finer and more quantitative method of study of the vestibular apparatus than gross studies. We, in the United States, have lagged behind our European confreres in its use. However, ENG presents two major problems. There are difficulties with maintenance and repair.

Study of Ventilation Testing with Electronystagmography

Annals of Otology, Rhinology & Laryngology, 1981
Provocation tests such as head shaking and positional tests, as well as hyperventilation, have been used routinely by many laboratories to elicit nystagmus during an electronystagmogram. We added oxygen testing to this routine battery and compared the results with hyperventilation and other forms of provocative testing.

Electronystagmography Recording System

Archives of Otolaryngology - Head and Neck Surgery, 1967
CLINICIANS using electronystagmography (ENG) for evaluation of vestibular function, should have instruments that are portable, not expansive, simple to operate, and provide recordings with minimal drifting and artifacts. Obviously the stimulus to induce nystagmus must remain constant from patient to patient.

Variations in Calibration for Computerized Electronystagmography

British Journal of Audiology, 1999
The accuracy of the analyses of vestibular test results obtained from a computerized electronystagmography (ENG) system depends on the accuracy with which the system has been calibrated to record the patient's eye movements. The variability of the calibration sensitivity was investigated by analysing the records of 50 consecutive patients who attended ...

Electronystagmography in Neurological Diagnosis

Stereotactic and Functional Neurosurgery, 1979
Electronystagmography (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].

Electronystagmography and horizontal directionalization

The Journal of Laryngology & Otology, 1984
A 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 ...

Three Derivations in Electronystagmography

Acta Oto-Laryngologica, 1969
In 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: A Systematic Approach

Archives of Otolaryngology - Head and Neck Surgery, 1984
This basic textbook and introduction to electronystagmography (ENG) is organized with a foreword by Dr Claus-F. Claussen, a preface, and an introduction. The chapters thereafter discuss the following topics: anatomy and physiology, medical history and physical examination, the fundamentals of ENG, the ENG procedure, evaluation of the ENG, the ...

New Possibilities of Analysis in Electronystagmography

Acta Oto-Laryngologica, 1972
The authors have introduced vectonystagmo-graphy for the computer analysis of electronystagmo-grams. The ψ angle determining the direction of the rapid eye movements and the $ angle between the first and the second, and between the first and the third channels have been measured. The variables have been defined.

Electronystagmography in Patients With Vestibular Disorders

Archives of Otolaryngology - Head and Neck Surgery, 1967
IN RECENT years electronystagmography (ENG) has emerged as a relatively simple diagnostic technique. Although the clinical value of nystagmus as a measure of vestibular activity is not in question, heretofore there have been few methods available for the adequate, objective evaluation of this important phenomenon.
