Sensory input evokes low-order reflexes and higher-order perceptual responses. Vestibular stimulation elicits vestibular-ocular reflex (VOR) and self-motion perception (e.g., vertigo) whose response durations are normally equal. Adaptation to repeated whole-body rotations, for example, ballet training, is known to reduce vestibular responses. We investigated the neuroanatomical correlates of ve...

Vestibular physical therapy is a specialized exercise based intervention for management of symptoms associated with vestibular dysfunction that manifests itself as dizziness and imbalance related to position or movement of the body. The aim of this review is to evaluate and summarize the efficacy of vestibular physical therapy for the treatment of vestibular disorders. A literature review was c...

One of the most important applications of the Brainstem evoked response audiometry (ABR) is in the evaluation of hearing loss in children. Today the ABR is also indicated in the screening of cochleo-vestibular syndromes to detect retrocochlear lesions, to monitor patients in a coma (brain death), in monitoring the brainstem during skull base surgery, etc. Among the many BERA qualities, is its c...

Using electronystagmography, we tested 100 patients (ages 65-80 years) manifesting the clinical signs of presbyvertigo, for the purpose of demonstrating their visuoocular reflexes. We administered not only simple optokinetic and eye-tracking stimuli but caloric modification of each one as well (with contrary directed optokinetic trace movement). The results were compared with those obtained in ...

Target Population Adults with histologically proven or suspected vestibular schwannomas with neurofibromatosis type 2 (NF2). Question What is the role of bevacizumab in the treatment of patients with vestibular schwannomas? Recommendations Level 3: It is recommended that bevacizumab be administered in order to radiographically reduce the size or prolong tumor stability in patients with NF2 ...

The present study examines the quality of binocular coordination of saccades at far and near distance in 15 children with symptoms of vertigo headache and equilibrium disorders; these children show normal vestibular function but abnormal convergence eye movements (e.g., long time preparation, slow execution and poor accuracy, see ). The results show normal binocular saccade coordination at far ...

This review focuses on the tissue/planar cell polarity (PCP) pathway and its role in generating spatial patterns in vertebrates. Current evidence suggests that PCP integrates both global and local signals to orient diverse structures with respect to the body axes. Interestingly, the system acts on both subcellular structures, such as hair bundles in auditory and vestibular sensory neurons, and ...

Brain magnetic resonance imaging (MRI) is the gold standard for diagnosing a vestibular schwannoma (VS). The prevalence of VS ranges from 0.02-2.4%; the incidence is 20 per million per year. This case report describes two cases of VS identified on brain MRIs that were not related to the purpose of the MRI examination. A literature search was performed to find existing audiometric-based protocol...

BACKGROUND Unilateral peripheral vestibular dysfunction (UPVD) can occur as a result of disease, trauma or post-operatively. The dysfunction is characterized by complaints of dizziness, visual or gaze disturbances and balance impairment. Current management includes medication, physical manoeuvres and exercise regimes, the latter known collectively as vestibular rehabilitation (VR). OBJECTIVES...
