Disease relevance of Electronystagmography

• Fourteen patients with cervicogenic headache (9F, 5M) with a mean age of 42.8 (29-58) years were examined, before and within two hours after unilateral anaesthetic C2-blockades, clinically as well as by means of electronystagmography, subjective visual vertical test and posturography [1].
• OBJECTIVES--To review the clinical features, electronystagmography findings, the possible mechanism, and a possible therapeutic approach to benign paroxysmal positional vertigo (BPPV) [2].
• However, a highly elevated titre of antibodies against the human acetylcholine receptor and a significant improvement in clinical symptoms during therapy with anticholinesterase drugs, combined with a decremental response in electronystagmography, indicated an intermittent mainly oculo-bulbar form of myasthenia gravis [3].
• The effects of air, helium-oxygen (6.4 ATA), and ethyl alcohol (40% by volume at a dose of 1.5 ml/kg body weight) were examined on the gain, number of beats, and phase lag of the vestibular ocular reflex (VOR) by means of electronystagmography (n = 7) [4].

High impact information on Electronystagmography

• The nystagmus resolved as the serum phenytoin level fell, as demonstrated by electronystagmography [5].
• METHODS: Patients with downbeat nystagmus were rechecked by electronystagmography (ENG); then 0.5 mg clonazepam was administered orally [6].
• Electronystagmography showed a right-beating nystagmus with predominantly linear slow phases that traversed the midline [7].
• In addition, all had been evaluated with gadolinium-enhanced magnetic resonance imaging and conventional electronystagmography [8].
• Although there are numerous text books and long articles written on electronystagmography, there are few comprehensive summary tables to assist in teaching ENG interpretation [9].

Biological context of Electronystagmography

• Eye movements were recorded with direct-current electronystagmography (DC-ENG) and a 12-bit analog to digital converter was used to collect analog data of horizontal and vertical eye position, and stimulus signals at a sampling rate of 200 Hz [10].

Anatomical context of Electronystagmography

• Postoperatively, both were relieved of their BPPV and demonstrated preserved lateral semicircular canal function as measured by electronystagmography [11].

Associations of Electronystagmography with chemical compounds

• Standard caloric testing with electronystagmography was performed before and after the heliox dives [12].
• In a series of studies, the phenomenon of head-shaking nystagmus (HSN) was assessed in 50 control subjects and 1364 consecutive dizzy patients who underwent formal electronystagmography (ENG) at the Toronto Hospital Center for Advanced Hearing and Balance Testing [13].
• The amount of streptomycin administered (5 to 50 g) was determined by clinical symptoms and by serial testing of the reduction in the slow-phase velocity on electronystagmography [14].
• Diazepam tolerance effects on vestibular function testing, Part I: Saccadic parameters during electronystagmography [15].
• Balance disorders detected by means of this test showed high compatibility with results of electronystagmography which confirmed damage of the central part of vestibular system due to CS2 intoxication [16].

Gene context of Electronystagmography

• This is diagnosed by the history, ear nose, throat and otoneurological examination, the audiological studies, electronystagmography, radiological tests using the Compere unit, the CT Scan, and when indicated the posterior fossa myelogram [17].
• Electronystagmography findings in child unilateral sensorineural hearing loss of probable viral origin [18].
• The Southern California Postrotary Nystagmus Test and electronystagmography under different conditions of visual input [19].
• Electronystagmography and examination of CSF are at least essential for the diagnosis of MS as VEPs [20].
• Electronystagmography in a patient with recent disequilibrium and a family history of otosclerosis [21].
