Vestibular migraine as a mimic of benign paroxysmal positioning vertigo and Meniere's disease
Vestibular migraine (VM) is a common cause of recurrent spontaneous and positional dizziness of varying durations. Short episodes of VM lasting seconds to minutes, triggered by changes in head position can resemble those of benign paroxysmal positioning vertigo (BPPV), while episodes lasting minutes to hours can mimic those of Meniere's disease (MD).
Simulator sickness among helicopter pilots: Incidence, threshold and severity using the SSQ
Flight simulators have an essential role in aircrew training. Occasionally, symptoms of motion sickness, defined as simulator sickness, develop during training sessions. The reported incidence of simulator sickness ranged widely in different studies.
Effects of monaural sound stimulation on subjective visual vertical
Sound stimulation can influence electrophysiological vestibular reflexes. However, the effects of sound stimulation on space perception remain unknown.
The vertical computerized rotational head impulse test
The computerized rotational head impulse test (crHIT) uses a computer-controlled rotational chair to deliver whole-body rotational impulses to assess the semicircular canals. The crHIT has only been described for horizontal head plane rotations. The purpose of this study was to describe the crHIT for vertical head plane rotations. In this preliminary study, we assessed four patients with surgically confirmed unilateral peripheral vestibular abnormalities and two control subjects. Results indicated that the crHIT was well-tolerated for both horizontal head plane and vertical head plane stimuli. The crHIT successfully assessed each of the six semicircular canals. This study suggests that the crHIT has the potential to become a new laboratory-based vestibular test for both the horizontal and vertical semicircular canals.
Evaluation of the reliability and validity of the upright head roll test for lateral semicircular canal benign paroxysmal positional vertigo
The upright head roll test (UHRT) is a recently introduced diagnostic maneuver for lateral semicircular canal benign paroxysmal positional vertigo (LSC-BPPV).
Sense of direction in vestibular disorders
Our sense of direction (SOD) ability relies on the sensory integration of both visual information and self-motion cues from the proprioceptive and vestibular systems. Here, we assess how dysfunction of the vestibular system impacts perceived SOD in varying vestibular disorders, and secondly, we explore the effects of dizziness, migraine and psychological symptoms on SOD ability in patient and control groups.
Sound and postural control during stance tasks in abnormal subjective haptic vertical
Patients with vestibular impairment often suffer from postural instability. This could be compensated by other sensory systems such as the auditory system.
Prevalence of benign paroxysmal positional vertigo in a population-based setting among 75-year-olds
Benign paroxysmal positional vertigo (BPPV) is one of the most frequently diagnosed cause of dizziness among older adults.
Local spatial navigation or "steering" in patients with vestibular loss in a virtual reality environment
Patients with vestibular loss have reduced wayfinding ability, but the association between vestibular loss and impaired steering spatial navigation is unclear.
Dynamic change of vestibular function and the long-term prognosis of vestibular neuritis
To comprehensively evaluate the dynamic change of vestibular function during long-term follow-up of vestibular neuritis, as well as the co-relationship with the outcomes of vestibular neuritis (VN), which provides the recommendations for vestibular function tests during the course of VN.
Dizziness-related disability in persons with post-COVID condition: A cross sectional study
Dizziness is a common symptom in post-COVID condition (PCC) which may have a large impact on several life domains. However, knowledge on dizziness-severity and disability in PCC is sparse.
Visual vertigo in children: Adaptation and validation of the visual vertigo analogue scale to European Portuguese
Visual vertigo occurs after vestibular and non-vestibular pathology and can be present in children and adolescents. It can be assessed by "the Visual Vertigo Analogue Scale" (VVAS), a questionnaire with a Portuguese version for adults.
Comparing in-clinic versus telehealth for vestibular physical therapy
Vestibular rehabilitation (VR) is a commonly employed treatment method for disorders of dizziness and imbalance. Access to a clinic for rehabilitation appointments can be challenging for a person experiencing dizziness. Telehealth may offer a comparable alternative to clinic-based VR for some patients.
Visual scale to document acute dizziness in the hospital
Managing acute vertigo/dizziness for inpatients requires valid communication between the various healthcare professionals that triage such life-threatening presentations, yet there are no current scaling methods for managing such acute vertigo symptoms for inpatients.
Normalization of the Suppression Head Impulse Test (SHIMP) and its correlation with the Head Impulse Test (HIMP) in healthy adults
In our study, it was aimed to compare vestibulo-ocular reflex (VOR) gain and saccade parameters in HIMP and SHIMP tests between gender, right and left ears, and age groups in healthy adults and to examine the correlation between the tests regarding these parameters.
The value of saccade metrics and VOR gain in detecting a vestibular stroke
A normal video Head Impulse Test is the gold standard in the emergency department to rule-in patients with an acute vestibular syndrome and a stroke. We aimed to compare the diagnostic accuracy of vHIT metrics regarding the vestibulo-ocular reflex gain and the corrective saccades in detecting vestibular strokes.
Investigating health disparities in vestibular rehabilitation
Health disparities (HD) impact care delivery and health outcomes in individuals with vestibular disorders (IVD).
Vestibular evoked myogenic potential (VEMP) test-retest reliability in adults
The technique of measuring ocular vestibular evoked myogenic potentials (oVEMP) in response to Mini-shaker vibration is relatively new, there is a limited normative data to define the presence or absence of a response in the literature.
Recovery of turning speed in patients after vestibular schwannoma resection
Individuals after a vestibular schwannoma resection (VSR) experience significant vestibular symptoms that can be provoked with turning. Vestibular rehabilitation assists in recovery of function and symptom relief, however turning response is unknown.
Analysis of postural stability using foam posturography in patients with persistent postural-perceptual dizziness
Persistent postural-perceptual dizziness (PPPD) is worsened in a standing posture, or by body movement, or visual stimulation. We aimed to evaluate postural stability in PPPD patients using foam posturography and to investigate the dependence on visual and somatosensory input in the standing posture.
Psychometrics of inertial heading perception
Inertial self-motion perception is thought to depend primarily on otolith cues. Recent evidence demonstrated that vestibular perceptual thresholds (including inertial heading) are adaptable, suggesting novel clinical approaches for treating perceptual impairments resulting from vestibular disease.
