UNLABELLED The vestibular evoked myogenic potential (VEMP) test is a relatively new diagnostic tool that is in the process of being investigated in patients with specific vestibular disorders. Briefly, the VEMP is a biphasic response elicited by loud clicks or tone bursts recorded from the tonically contracted sternocleidomastoid muscle, being the only resource available to assess the function ...

The present study investigated goal-directed linear locomotion in nine Menière's patients before and after (1 week, 1 and 3 months) a curative unilateral vestibular neurotomy (UVN). Experiments were done using a 3D motion analysis system in subjects walking eyes open (EO) and eyes closed (EC) towards a real or memorized target, respectively. Locomotor pattern (velocity, step length, step freque...

OBJECTIVES To analyze the clinical characteristics of vestibular neuritis patients with minimal canal paresis (canal paresis <25%). METHODS Patients clinically diagnosed with vestibular neuritis and treated at our institute (n=201) underwent otoneurological examination and vestibular function tests. Patients were categorized in terms of the results of caloric testing (canal paresis<25%, n=58;...

OBJECTIVE The aim of this study was to assess the subjective visual vertical in patients with bilateral vestibular dysfunction and to propose a new method to analyze subjective visual vertical data in these patients. METHODS Static subjective visual vertical tests were performed in 40 subjects split into two groups. Group A consisted of 20 healthy volunteers, and Group B consisted of 20 patie...

After vestibular labyrinth injury, behavioral measures of vestibular function partially recover through the process of vestibular compensation. The present study was performed to improve our understanding of the physiology of macaque vestibular nucleus neurons in the compensated state (>6 wk) after unilateral labyrinthectomy (UL). The responses of neurons to sinusoidal yaw rotation at a series ...

Reports of vestibular deficits and related impairments in children are increasing in number. However, vestibular dysfunction in childhood appears to be an under-reported and overlooked entity. This report provides an overview of current literature regarding the incidence of vestibular deficits in children, the related impairments of gaze stability and balance and intervention for vestibular rel...

Recent epidemiological investigations have highlighted the high prevalence of vestibular dysfunctions in the adult population and its association with aging. Despite a large and unmet medical need, the pharmaceutical options of targeted and efficient drugs to reduce the symptoms associated with vestibular deficits remains largely insufficient. This special issue of the Journal of Vestibular Res...

The present study evaluated the effectiveness of electrotactile tongue biofeedback (BrainPort((R))) as a sensory substitute for the vestibular apparatus in patients with bilateral vestibular loss (BVL) who did not have a good response to conventional vestibular rehabilitation (VR). Seven patients with BVL were trained to use the device. Stimulation on the surface of the tongue was created by a ...

Dizziness and vertigo without neurological signs are typically due to a peripheral vestibular disease. Although the most common causes are benign, differential diagnosis must include potentially life-threatening central diseases such as cerebrovascular pathologies. A systemic clinical approach needs a careful work-up, bedside examination and appropriate instrumental investigation. The head impu...
