OBJECTIVE The Dix-Hallpike test is a standard component of the videonystagmography test battery and can diagnose posterior semicircular canal benign paroxysmal positional vertigo. The purpose of this study is to determine the prevalence of discordant, equivocal, and concordant nystagmus tracings in active posterior semicircular canal benign paroxysmal positional vertigo when compared directly w...

Abstract Dizziness is a common symptom in medicine. The anamnesis and detection of nystagmus essential to distinguish vertigo's pathogenesis. diagnosis complex, expensive, not always available across the board. We present novel location- time-independent mobile application for videonystagmography (VNG) support vertigo patients medical staff. No additional hardware necessary. app uses artificial...

OBJECTIVE To characterise balance disorders occurring after head trauma, using videonystagmography, and to test the efficiency of videonystagmography as a diagnostic and monitoring tool. METHOD Prospective, cohort analysis of 126 head trauma patients managed with vestibular evaluation, monitoring and treatment, in a tertiary referral centre. Analytical parameters included: head injury severit...

UNLABELLED Electronystagmography (ENG) and videonystagmography (VNG) are eye movement recording methods used for the evaluation of balance disorders. AIM To compare literature information on the similarities, differences, advantages e disadvantages between ENG and VNG. MATERIALS AND METHODS review of the scientific literature. RESULTS ENG and VNG are very helpful methods for evaluating ba...

Videonystagmography (VNG) is a complete diagnostic system for recording, analyzing, and reporting eye movements using video imaging technology, in which hi-tech goggles with infrared cameras are used. VNG includes series of tests used to determine whether vestibular disease may be causing balance or dizziness problem; can differentiate between central peripheral lesion, and, if peripheral, it d...

The aim of this study was to search for the reason for vertigo in children who complain of it. We tested 30 children who had been treated by a pediatrician for various diseases. We performed the detailed protocol of anamnesis, videonystagmography, posturography, and additional tests ordered by the pediatrician and then compared the results of these procedures with those of a group of 30 healthy...

PURPOSE The purpose of this study was to establish a set of normative data values for saccade movements using videonystagmography and to evaluate the effects of manual correction on this data. METHODS We examined 25 healthy subjects (9 men and 16 women). All tests were carried out by one well-instructed physician. Errors such as the wrong detection of the inflection point, missing movement, a...

OBJECTIVES Vertigo is a very common symptom mainly caused by the lesion of vestibular system (peripheral or central) and often accompanied by some work-related diseases and occupational intoxications. The aim of this study was to assess the value of electronystagmography (ENG) and videonystagmography (VNG) for diagnosing vertigo of various origin. MATERIALS AND METHODS The study included four...
