Electronystagmography (ENG) is a diagnostic test to record involuntary movements of the eye caused by a condition known as nystagmus. It can also be used to diagnose the cause of vertigo, dizziness or balance dysfunction by testing the vestibular system. [1] Electronystagmography is used to assess voluntary and involuntary eye movements. [2]
The physiologic basis of the head tilt test was explained by Alfred Bielschowsky and Hofmann [8] in 1935.

As the eyes converge, the pupils should constrict. The optokinetic nystagmus test is optional and involves asking the patient to look at a strip of vertical lines moving horizontally across visual field. Nystagmus is normally observed. Extraocular movements are tested by inspecting for ptosis, eye position and nystagmus. The pupil size is ...
The individual is conscious and sufficiently intact cognitively to be able to communicate with eye movements. [4] Electroencephalography results are normal in locked-in syndrome. Total locked-in syndrome , or completely locked-in state ( CLIS ), is a version of locked-in syndrome wherein the eyes are paralyzed as well. [ 5 ]
