Evaluation of Bilateral Vestibular Dysfunction in Iranian Adults and Elderlies by Electronystagmography and Video Head Impulse Test
Introduction: Vestibular abnormalities are common problems in the whole world, which can lead to bilateral vestibular dysfunction (BVD). That results in symptoms, such as vertigo, unsteadiness, falling, oscillopsia, and lower quality of life. The Objective of this study was to determine BVD in adults and elderlies with vertigo and unsteadiness. Materials and Methods: This study was conducted ...
متن کاملVertical eye movements during horizontal head impulse test: a new clinical sign of superior vestibular neuritis
In some patients suffering from acute unilateral peripheral vestibular deficit, the head impulse test performed towards the affected side reveals the typical catch-up saccade in the horizontal plane, and an oblique, mostly vertical, upward catch-up saccade after the rotation of the head towards the healthy side. Three cases are reported herein, which have been studied using slow motion video an...
متن کاملRelationship between video head impulse test (vHIT) and caloric test in patients with vestibular neuritis.
INTRODUCTION AND OBJECTIVES The caloric test is the gold standard for the loss of vestibular function diagnosis. The Video Head Impulse Test (vHIT) assesses the same reflex by using a video- assisted examination of the impulsive maneuver. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at...
متن کاملSensitivity of caloric test and video head impulse as screening test for chronic vestibular complaints
OBJECTIVE: This study compared the results of the caloric test with those of the video head impulse test obtained during the same session and evaluated whether the former can be used to screen for non-acute vestibular dysfunction. METHODS: A total of 157 participants complaining of dizziness with vestibular characteristics of varying durations and clinical courses completed the caloric test a...
متن کاملHead Impulse Test
In 1988, Michael Halmagyi and Ian Curthuoys described a simple yet reliable indicator of unilateral peripheral vestibular deficits at the bedside. This 'head impulse test' (HIT) as is has been known since, has stood the test of being a reliable indicator of vestibular deficit, especially for the horizontal semicircular canal. The test has been described using various techniques, such as the scl...
