Vestibular dysfunction causes postural instability, which is prevalent in the elderly. We previously showed that an imperceptible level of noisy galvanic vestibular stimulation (nGVS) can improve postural stability in patients with bilateral vestibulopathy during the stimulus, presumably by enhancing vestibular information processing. In this study, we investigated the after-effects of an imper...

This review summarizes our current knowledge of multisensory vestibular structures and their functions in humans. Most of it derives from brain activation studies with PET and fMRI conducted over the last decade. The patterns of activations and deactivations during caloric and galvanic vestibular stimulations in healthy subjects have been compared with those in patients with acute and chronic p...

Introduction: Temporomandibular joint dysfunction (TMD) is caused by inflammation of the ligaments and muscles surrounding joints. TMD associated with several comorbidities, one these comorbidities are otological problems. The symptoms related to tinnitus, otalgia, ear fullness, Vertigo. Vertigo observed in many diseases etiologic factors should be investigated increase efficiency treatment Obj...

Dizziness is a common symptom in medical practice, and may be associated with over 300 diseases. Although most cases of dizziness are related to vestibular system dysfunction, some result from involvement of other parts of the body. Recent studies have shows that there is an association between auditory/vestibular symptoms and autonomous nervous system dysfunction, suggesting that this may be a...

The vestibular system plays a crucial role in the multisensory control of balance. When vestibular function is lost, essential tasks such as postural control, gaze stabilization, and spatial orientation are limited and the quality of life of patients is significantly impaired. Currently, there is no effective treatment for bilateral vestibular deficits. Research efforts both in animals and huma...

Electrophysiological activity in response to linear acceleration stimuli was recorded from young chickens by means of subcutaneous electrodes. This investigation had 2 purposes: (1) to establish the vestibular origin of the potentials; and (2) to investigate the contribution of each vestibular labyrinth to the response. The stimuli consisted of pulses of linear acceleration delivered by a mecha...

in this case report, a 36 year old female at 40 weeks' gestation is presented in whom large bilateral vestibular bulb masses were found on pelvic examination. the size of the masses was such as to cause concern that they may pose an impediment to normal parturition. our pathological findings, management and results are presented.

Vestibular schwannomas are the most common cerebellopontine angle tumors. These tumors commonly present with ipsilateral dysfunction of acoustic, vestibular, trigeminal, and facial nerves.1 Presentation of the vestibular schwannoma with contralateral facial nerve dysfunction is quite uncommon, and the contralateral facial paresis has been mentioned as a false localizing sign for posterior fossa...

The aim of the study was to uncover mechanisms of central compensation of vestibular function at brainstem, cerebellar, and cortical levels in patients with acute unilateral midbrain infarctions presenting with an acute vestibular tone imbalance. Eight out of 17 patients with unilateral midbrain infarctions were selected on the basis of signs of a vestibular tone imbalance, e.g., graviceptive (...

Damage to the vestibular labyrinth leads to profound nystagmus and vertigo. Over time, the vestibular-ocular system recovers in a process called vestibular compensation leading to reduced nystagmus and vertigo provided visual signals are available. Our study was directed at identifying sources of visual information that could play a role in vestibular compensation. Specifically, we investigated...
