OBJECTIVE:: To investigate whether transient, high-acceleration interaural head heaves (translational vestibulo-ocular reflex [tVOR]) could aid in the diagnosis of otolith diseases. STUDY DESIGN:: Prospective cohort study. SETTING:: Tertiary referral center. PATIENTS:: Thirteen patients with symptoms suggestive of otolith diseases and 10 age-matched controls. INTERVENTIONS:: Patients underwent ...

Optokinetic afternystagmus follows optokinetic nystagmus as an expression of the central velocity storage integrator discharge and its fast phase is beating in the same direction as the previous optokinetic nystagmus. We investigated the correlation between vestibulo-ocular reflex and optokinetic afternystagmus in normal subjects and in patients with bilateral vestibular disorders. The aim of t...
OBJECTIVE Bilateral vestibulopathy (BV) leads to a bilateral deficit of the vestibulo-ocular reflex and has various aetiologies. The main goal of this study was to determine the frequency and degree of recovery or worsening of vestibular function over time. METHODS 82 patients (59 males, 23 females; mean age at the time of diagnosis 56.3 (SD 17.6) years) were re-examined 51 (36) months after ...
PURPOSE Individuals with spinal cord injury or neurological disorders may have neurogenic detrusor contractions at low volumes (bladder hyperreflexia), which cause incontinence and can lead to significant health problems. Bladder contractions can be suppressed by electrical stimulation of inhibitory pathways but continuous activation may lead to habituation of the inhibitory reflex and loss of ...
INTRODUCTION Evidence is emerging for a significant clinical and neuroanatomical relationship between balance and anxiety. Research has suggested a potentially priming effect with anxiety symptoms predicting a worsening of balance function in patients with underlying balance dysfunction. We propose to show that a vestibular stimulus is responsible for an increase in state anxiety, and there is ...

Selective electroneurograms (ENGs) from superficial regions of the left vagus nerve of a dog were recorded with a 33-electrode spiral cuff (cuff) implanted on the nerve at the neck in an adult Beagle dog. The electrodes in the cuff were arranged in thirteen groups of three electrodes (GTE 1-13). To identify the relative positions of the particular nerve regions that innervated the heart and lun...
OBJECTIVES Patients with vestibular schwannoma (VS) frequently suffer from disabling vestibular symptoms. This prospective follow-up study evaluates vestibular and auditory function and impairment of quality of life due to vertigo, dizziness, and imbalance in patients with unilateral VS of different sizes before/after microsurgical or radiosurgical treatment. METHODS Thirty-eight patients wit...
INTRODUCTION AND OBJECTIVE Polygenic or multifactorial inheritance of chronic disorders (MICD) contribute to irreversible cochleovestibular impairment. Our aim was to determine the type and degree of cochleovestibular dysfunction (CVD) in patients with MICD. METHODS Cross-sectional. We studied 385 patients with type 2 diabetes mellitus, systemic arterial hypertension and dyslipidemia who were...
