R ecently, clinical vestibular tests have been developed for assessing otolith function. Little is known about treatment for otolith dysfunction, and this case report offers a perspective on using otolith stimulation to treat vestibular loss. A 62-year-old man underwent a left vestibu...

Objective Besides the gold standard, caloric reflex test, vertigo diagnosis is increasingly supplemented by video head impulse test (vHIT) for all six semicircular canals of vestibular organ. Therefore, aim this study to evaluate possible gain in diagnostic significance from combination different outcome parameters same and apparative examination methods (calorics, vHIT).Methods Diagnostic was ...

acoustic neuromas (an) are schwann cell-derived tumors that commonly arise from the vestibular portion of the eighth cranial nerve also known as vestibular schwannoma(vs) causes unilateral hearing loss, tinnitus, vertigo and unsteadiness. in many cases, the tumor size may remain unchanged for many years following diagnosis, which is typically made by mri. in the majority of cases the tumor is s...

Ocular vestibular evoked myogenic potentials (oVEMPs), subjective visual vertical (SVV), and fundus photographically measured binocular cyclorotation (BCR) are diagnostic tests to assess utricular function in patients with vertigo or dizziness. In 138 chronic dizziness, we asked whether the asymmetry ratio of oVEMP (normal, right side pathological, left pathological) could predict SVV deviation...

Introduction: Bilateral vestibular dysfunction (BVD) is an uncommon finding in vestibular assessment, and the combination of BVD and orthopedic problems represents a rare and challenging case for treatment.   Case Report: The patient had several previous back surgeries and received gentamycin after surgery. After 6 months, she experienced continuous dizziness, unsteadiness and oscillopsia. ...

The caloric test is quantified using two parameters: unilateral weakness (UW) and directional preponderance (DP). The clinical usefulness of UW, also known as canal paresis, is well established but there is considerable debate about the value of DP. Some laboratories choose not to include DP in the interpretation of the caloric test. One reason for the low clinical value of abnormal DP may be t...

The purpose of this study was to investigate the effects of caloric vestibular stimulation on the postural sway characteristics of hemiparetic patients. Two groups of 15 hemiparetic patients each (right and left) were compared to a group of 15 control subjects. Hemiplegic patients were selected for the study if they showed ability to stand without external support for at least 30 seconds. Postu...

One of the most recent and promising theoretical hypotheses for compensation of persistent asymmetry of dynamic vestibulo-ocular gain is sensory substitution. As a switch between oculomotor and vestibulo-ocular systems, saccadic eye movements are engaged in humans to compensate the angular displacement of the head towards the labyrinthine defective side thus preserving the foveal fixation of th...

Introduction: Vestibular rehabilitation is a treatment option for the management of vertigo and unsteadiness, which are very common in head trauma patients and more challenging in the early months after trauma. This study evaluated the effectiveness of a vestibular rehabilitation program in the recovery of acute and sub-acute head trauma patients. The goal of this study was evaluation of the ef...
