Falls in seniors are a major public health problem. Falls lead to fear of falling, reduced mobility, and decreased quality of life. Vestibular dysfunction is one of the fall risk factors. The relationship between objective measures of vestibular responses and age has been studied. However, the effects of age on vestibular perception during caloric stimulation have not been studied. Twenty senio...

INTRODUCTION The vestibular acute stress induces reversible alert-like reactions that involve the sympathetic adrenal-medullar system and hypothalamic-pituitary-adrenal axis responses. The present study aimed to evaluate salivary α-amylase and salivary cortisol production in relation with cardiovascular reactivity induced by acute stress in healthy subjects. MATERIAL AND METHODS Forty-eight y...

Rotatory chair testing of the horizontal semicircular canals is an important but specialized tool in vestibular examinations. This review summarizes stimulus protocols, basic physiology and the current knowledge. It will be shown that the value of rotatory testing in clinical practice is part of a vestibular test battery in high end vestibular and balance centers but not in a general clinical p...

Surgical removal of vestibular schwannoma causes acute vestibular symptoms, including postoperative vertigo and oscillopsia due to nystagmus. In general, the dominant symptom postoperatively is vertigo. Preoperative chemical vestibular ablation can reduce vestibular symptoms postoperatively. We used 1.0 mL of 40 mg/mL nonbuffered gentamicin in three intratympanic installations over 2 days, 2 mo...

  Background :Preterm birth is a significant global health problem with serious short- and long-term consequences. This study examined the long term effects of preterm birth on vestibular evoked myogenic potentials (VEMPs) among preschool-aged children.   Methods : Thirty-one children with preterm and 20 children with term birth histories aged 5.5 to 6.5 years were studied. Each child underwent...

OBJECTIVE To assess the short-term effectiveness of vestibular rehabilitation therapy in reducing fall risk in an at-risk population. STUDY DESIGN AND SETTING Retrospective chart review of 70 patients older than 50 years of age at risk for falls treated at a tertiary vestibular therapy center. Fall risk was assessed by the Berg balance test. RESULTS Vestibular rehabilitation therapy resulte...

Congenital deafness has a relationship with vestibular and motor functioning. However, many studies have focused on children rather than adults. This study compared the relationship of vestibular functioning and visual acuity between adult athletes who were deaf and their age-appropriate peers in order to understand differences in balance and vision. Specifically, balance capability, vestibular...

Vertigo is defined as a rotational sensation associated with nystagmus and often accompanied by nausea and vomiting, and somatic instability such as gait disturbance1. In patients with vertigo that occurs suddenly and subsides rapidly (within 24 hour) the caloric test, a vestibular dysfunction test, is generally negative. Because its underlying disease is poorly understood, and does not satisfy...

In vestibular examinations anomalies in the saccade and smooth pursuit tests as well as the fixation suppression after caloric stimulation might indicate central lesions in the vestibular system. Additionally, a high gain in the torsion test is suspicious of cerebellar dysfunction. In this study, 141 patients out of 973 had at least one of these anomalies. For 125 patients we were able to compa...
