Electronystagmography and Electrooculography
Ophthalmologica, 1974Nystagmus is defined as involuntary, rhythmically repeated oscillations of one or both eyes. Qualitative and quantitative recording of these oscillations is called nystagmography. Electronystagmography (ENG) and electrooculography (EOG) are based on the recording of variations of the standing potential.

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.

Neurologic Clinics, 1990
Electronystagmography in 1990 should identify a vestibular abnormality with which to associate the clinical symptoms. The vestibular test battery method and interpretation reveals its application in neurotologic diagnosis.

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.

Electronystagmography in the Office
Archives of Otolaryngology - Head and Neck Surgery, 1968THE 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.

Electronystagmography and Videonystagmography
2019Vestibular function tests are clinical techniques used to evaluate part of the vestibular system. Stimulation of the inner ear results in specific eye movement termed nystagmus, which are integral in the evaluation of the vestibular system. Nystagmus has a fast-phase and a slow-phase component and is named based on the fast phase. Electronystagmography

Electronystagmography Recording System
Archives of Otolaryngology - Head and Neck Surgery, 1967CLINICIANS 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.

Study of Ventilation Testing with Electronystagmography
Annals of Otology, Rhinology & Laryngology, 1981Provocation 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.

Variations in Calibration for Computerized Electronystagmography
British Journal of Audiology, 1999The 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 ...
