introduction: patients with bilateral weakness (bw) have many difficulties in gaze stability that interfere with their normal function. the aim of this study was to evaluate ocular motor functions in patients with bw to better understand the problem of gaze instability in these patients.   materials and methods: patients were referred from the otolaryngology department for vestibular assessment...

BACKGROUND AND PURPOSE This study explores the effect of vibrotactile biofeedback on gait in 20 patients with bilateral vestibular areflexia using observational gait analysis to score individual balance. METHODS A tilt sensor mounted on the head or trunk is used to detect head or body tilt and activates, via a microprocessor, 12 equally distributed vibrators placed around the waist. Two posit...

A unique case of initially right sided varicella zoster induced Ramsay-Hunt syndrome with complete vestibular loss is reported. The patient subsequently developed deficits of the left vestibule 5 months later. An autoimmune pathogenesis of the left vestibular failure rather than bilateral varicella zoster infection was suggested by the following data: (1) no evidence of vesicular eruptions on t...

The main tumor of cerebellopontine angle are vestibular schwannoma (80-90%). Most of them are unilateral lesion but 5% of them are bilateral pathological mass. There are genetic disease like neurofibromatosis type 1 and 2. According to National Institute of Heath Consensus Development Conference the best treatment method is microsurgery. The possibility of hearing preservation surgery give midd...

INTRODUCTION Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. OBJECTIVE To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. METHODS Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment f...

The authors studied patients with diabetes and complaints of dizziness to determine whether peripheral neuropathy or inner ear dysfunction was more likely to disturb balance. Quantitative testing showed that the majority failed to maintain balance in vestibular-related conditions and had normal equilibrium scores in conditions relying on somatosensory input. Vestibular dysfunction should be an ...

1 Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article. 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...

The purpose of this study was to investigate the effects of various levels of vestibular function on balance in two, free-standing rhesus monkeys. We hypothesized that postural control strategy depended on the severity of vestibular damage. More specifically, that increased muscle stiffness (via short-latency mechanisms) was adequate to compensate for mild damage, but long-latency mechanisms mu...

Cogan's syndrome is defined as a chronic inflammatory disease of unknown origin, an autoimmune disease, characterized by bilateral sensorineural hearing loss, vestibular symptoms, inflammatory ocular manifestations with variable risk of developing into a systemic disease. The onset of disease is variable but is often characterized by isolated ocular symptoms or acute ear and/or vestibular manif...

IMPORTANCE Bilateral vestibular failure is a debilitating condition that may lead to oscillopia and adversely affect quality of life. Researchers have suggested that vestibular function might be restored with implantation of an external mechanical stimulation device. However, it is essential that such a device must not interfere with normal hearing. OBJECTIVE To evaluate the effect of vestibu...
