UNLABELLED The subjective visual vertical (SVV) is usually considered a measure of otolith function. Herewith we investigate the influence of semicircular canal (SCC) stimulation on the SVV by rotating normal subjects in yaw about an earth-vertical axis, with velocity steps of +/- 90 degrees /s, for 60 s. SVV was assessed by setting an illuminated line to(More)
Previous studies have looked at co-processing of multiple proprioceptive inputs but few have investigated the effect of separate dynamic and tonic predominantly proprioceptive disruptions applied concurrently at the same segment. The purpose of the present study was to investigate how simultaneous ankle tendon vibration, a tonic stimulus, with a dynamic(More)
UNLABELLED Patients with chronic vestibular symptoms are common in neurological practice but the most effective treatment remains an open question. The purpose of our study was to conduct a controlled, between-group comparison of patients' responses to a customised exercise regime (Group C, for customised) versus treatment additionally incorporating(More)
Patients with vestibular dysfunction, migraine and/or anxiety may experience visual vertigo (VV), whereby symptoms are provoked by disorienting visual environments (e.g. supermarkets). Patients with VV over rely on vision for balance (i.e. visually dependent). Visual vertigo significantly improves when vestibular rehabilitation incorporates exposure to(More)
BACKGROUND Visual vertigo (VV) symptoms improve only when customized vestibular rehabilitation (VR) integrates exposure to optokinetic stimuli (OK). However, equipment is expensive, biweekly sessions are not standard practice, and therapy is often unsupervised. METHODS A controlled, parallel-group comparison was made of patients' responses to an 8-week(More)
BACKGROUND vestibular disorders are common in the general population, increasing with age. However, it is unknown whether older adults who fall have a higher proportion of vestibular impairment compared with age-matched older adult non-fallers. OBJECTIVE to identify whether a greater proportion of older adult fallers have a peripheral vestibular(More)
Many daily activities require appropriate allocation of attention between postural and cognitive tasks (i.e. dual-tasking) to be carried out effectively. Processing multiple streams of spatial information is important for everyday tasks such as road crossing. Fifteen community-dwelling healthy older (mean age=78.3, male=1) and twenty younger adults (mean(More)
Individuals with vestibular dysfunction may experience visual vertigo (VV), in which symptoms are provoked or exacerbated by excessive or disorienting visual stimuli (eg, supermarkets). Individuals with VV are believed to be overly reliant on visual input for balance (ie, visually dependent). VV can significantly improve when customized vestibular(More)
OBJECTIVE To develop and validate the Pediatric Vestibular Symptom Questionnaire (PVSQ) and quantify subjective vestibular symptom (ie, dizziness, unsteadiness) severity in children. STUDY DESIGN One hundred sixty-eight healthy children (female, n = 91) and 56 children with postconcussion dizziness or a vestibular disorder (female, n = 32), between ages 6(More)
