The Video Head Impulse Test
In 1988, we introduced impulsive testing of semicircular canal (SCC) function measured with scleral search coils and showed that it could accurately and reliably detect impaired function even of a single lateral canal. Later we showed that it was also possible to test individual vertical canal function in peripheral and also in central vestibular disorders and proposed a physiological mechanism...

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 کاملEF FECTS OF THE VALSALVA MANEUVER AND HEAD ROTATION ON INTERNAL JUGULAR VEIN DIAMETER AND LOCATION BY ULTRASONOGRAPHY
In order to determine the effect of Valsalva maneuver and head rotation on the internal jugular vein (IJV) diameter and cross-sectional area and overlap with the carotid artery (CA) and find the best technique for safe cannulation of the IJV and decrease the risk of CA puncture, the diameter of both the IJV and the CA and percentage of overlap between the two vessels and cross-sectional are...
