Vertigo in pilots

BACKGROUND: Meniere's disease (MD) is defined by episodic vertigo, unilateral sensorineural hearing loss and fluctuating aural symptoms. Due to the variable clinical presentation, objective tests of MD may have significant diagnostic utility. Head kinematics derived from a head-mounted display (HMD) have demonstrated to be sensitive to vestibular dysfunction. The purpose of this pilot study was to investigate whether head sway can differentiate between patients with MD, vestibular hypofunction (VH) and healthy controls...

BACKGROUND: We created a clinical virtual reality application for vestibular rehabilitation. Our app targets contextual sensory integration (C.S.I.) where patients are immersed in safe, increasingly challenging environments while practicing various tasks (e.g., turning, walking). The purpose of this pilot study was to establish the feasibility of a randomized controlled trial comparing C.S.I. training to traditional vestibular rehabilitation. METHODS: Thirty patients with vestibular dysfunction completed the Dizziness Handicap Inventory (DHI), Activities-Specific Balance Confidence Scale (ABC), Visual Vertigo Analog Scale (VVAS), Functional Gait Assessment (FGA), Timed-Up-and-Go (TUG), and Four-Square Step Test (FSST)...

Introduction  Degenerative changes in the otolithic organs have been theorized to be caused by the mechanical obstruction to endolymphatic flow, possibly resulting in endolymphatic hydrops (ELH). Otolin-1 is an otoconial matrix protein that crosses the blood labyrinth barrier and has been found in the serum of healthy and diseased patients. Objective  To measure the serum levels of Otolin-1 in Meniere disease (MD) patients and compared them with the healthy individuals. Methods  This pilot, cross-sectional study was performed at our tertiary care referral center to compare the serum Otolin-1 levels of healthy individuals with those of MD patients...

OBJECTIVE: The paediatric caregiver version of the Dizziness Handicap Inventory (DHI-PC) questionnaire is a useful Quality of Life (QoL) evaluation instrument for children experiencing dizziness, vertigo or unsteadiness. Its English version has been validated for use with a paediatric population between 5 and 12 years of age. The aim of this work is to validate the DHI-PC into Italian for both patient assessment and appropriate rehabilitative treatment planning. MATERIALS AND METHODS: Cross-cultural adaptation of the DHI-PC was performed using standard techniques...

This prospective pilot study aimed to evaluate whether cerebral inflow and outflow abnormalities assessed by ultrasonographic examination could be associated with recurrent benign paroxysmal positional vertigo (BPPV). Twenty-four patients with recurrent BPPV, affected by at least two episodes, and diagnosed according to American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria, evaluated at our University Hospital, between 1 February 2020 and 30 November 2021, have been included. At the ultrasonographic examination, 22 of 24 patients (92%) reported one or more alterations of the extracranial venous circulation, among those considered for the diagnosis of chronic cerebrospinal venous insufficiency (CCSVI), although none of the studied patients were found to have alterations in the arterial circulation...

Context: Interprofessional teams can reduce workload of primary care providers (PCP). Currently, there is no standardization regarding which professionals should be on the team. We completed a 2 year pilot imbedding an occupational therapist (OT) within a family medicine team. Our initial findings showed significant satisfaction among PCPs. This current study further analyses the outcomes from this pilot. Objective: To examine the treatment plans and corresponding outcomes for all patients that were seen by an OT in order to assess the impact on patients of integrating OT into a primary care setting...

BACKGROUND: Visual vertigo (VV) is a common symptom in people with persistent postural-perceptual dizziness (PPPD). Few subjective scales are validated for assessing the intensity of VV, yet these scales are limited by recall bias, as they require individuals to rate their symptoms from memory. The computer-Visual Vertigo Analogue Scale (c-VVAS) was developed by adapting five scenarios from the original paper-VVAS (p-VVAS) into 30 s video clips. The aim of this pilot study was to develop and test a computerized video-based tool for the assessment of visual vertigo in people with PPPD...

PURPOSE: The present study aimed to construct and validate a Swedish translation (VVAS-S) of the Visual Vertigo Analogue Scale (VVAS). MATERIALS AND METHODS: The original English VVAS was translated into Swedish by the two authors and back-translated by an independent professional translator. Pilot-tests were performed on two healthy participants and five patients suffering from Visually Induced Dizziness (VID). The translation was deemed understandable by all subjects...

Performing an accurate canalith repositioning procedure (CRP) is important for treating benign paroxysmal positional vertigo, because inadequate rotational head angles can result in ineffective otolith mobilization and consequent treatment failure. Specialists-guided Epley maneuver reportedly had mean errors of 13.7°-24.4° while they were significantly larger (40.0°-51.5°) when self-administered. Similar results were obtained for the Barbeque maneuver: mean errors were 9.2°-13.0° by the specialists while they were significantly larger (22...

STUDY OBJECTIVE: To compare nifedipine, naproxen, or placebo for pain relief during diagnostic hysteroscopy. DESIGN: Double-blind, randomized controlled pilot study. SETTING: University hospital. PATIENTS: Women scheduled for office diagnostic hysteroscopy (n = 60). INTERVENTIONS: Women received nifedipine (2 tablets of 10 mg), naproxen (2 tablets of 250 mg), or placebo (2 tablets of 500 mg lactose) 30 to 60 minutes prior to hysteroscopy...

BACKGROUND: Vertigo, dizziness or balance disorders (VDB) are common leading symptoms in older people, which can have a negative impact on their mobility and participation in daily live, yet, diagnosis is challenging and specific treatment is often insufficient. An evidence-based, multidisciplinary care pathway (CPW) in primary care was developed and pilot tested in a previous study. The aim of the present study is to evaluate the effectiveness and safety of the CPW in terms of improving mobility and participation in community-dwelling older people with VDB in primary care...

The aim of this study is to establish a relationship between vitamin D levels and benign paroxysmal positional vertigo (BPPV) and its recurrence; and to evaluate the remedial effect of vitamin D on BPPV. In a pilot study, 40 patients with clinically diagnosed posterior canal BPPV were evaluated, treated and were followed up for a period of 6 months at ENT Department of Mahatma Gandhi Medical College, Jaipur. All the patients with clinical diagnosis of posterior canal BPPV were tested for 25(OH)D levels at their 1st visit...

BACKGROUND: Walking among crowds avoiding colliding with people is described by patients with vestibular disorders as vertigo-inducing. Accurate body motion while circumventing an impeding obstacle in the gait pathway is dependent on an integration of multimodal sensory cues. However, a direct role of vestibular signals in spatial perception of distance or orientation during obstacle circumvention has not been investigated to date. MATERIALS AND METHODS: We examined trunk yaw motion during circumvention in patients with acute unilateral vestibular loss (aUVL) and compared their results with age-matched healthy controls (HCs)...

Objective: To cross-culturally adapt the Meniere's Disease Outcomes Questionnaire（MDOQ） into Chinese language, to evaluate its reliability and validity, and to apply in clinical. Methods: The MDOQ was translated according to the Brislin model. Cross-cultural adaption was done by expert discussion and pilot study. The MDOQ was applied to 101 patients to test its reliability and validity. The quality of life（QOL） of 272 patients was measured by MDOQ-C, analyzing the influence factors of QOL of patients with Meniere's disease...

BACKGROUND: Effective symptom control is a stated goal of palliative care (PC) to improve quality of life for terminally ill patients. Virtual reality (VR) provides temporary escapes from pharmacologically resistant pain and allows for experiences and journeys patients may not access in any other way. Enabling wishes through virtual worlds may also offer additional benefits such as controlling psychological and physical symptoms. AIMS: We investigated the feasibility of a single VR experience as a viable, satisfying, and effective tool for end-of-life pain relief for inpatients presenting palliative needs...

BACKGROUND: Although the coronavirus disease 19 (COVID-19) pandemic has now impacted the world for over two years, the persistent secondary neuropsychiatric effects are still not fully understood. These "long COVID" symptoms, also referred to as post-acute sequelae of SARS-CoV-2 infection (PASC), can persist for months after infection without any effective treatments. Long COVID involves a complex heterogenous symptomology and can lead to disability and limit work. Long COVID symptoms may be due to sustained inflammatory responses and prolonged immune response after infection...

BACKGROUND: Tinnitus and vertigo have been studied in many ways. This led to a variety of explanations from multiple medical disciplines. The musculature of the jaw and cervical spine have also been researched in this regard. Dysfunctional musculature can trigger tinnitus and dizziness. This subtype of tinnitus is called cervicogenic somatosensory tinnitus. OBJECTIVE: The aim of the present study was to investigate the effect of manual therapy on subject-reported, individually perceived impairment due to cervicogenic somatosensory tinnitus (Tinnitus Handicap Inventory), dizziness (Dizziness Handicap Inventory), and hypertonia of the musculature of the head and cervical spine...

Vestibular neuritis was first reported in 1952 by Dix and Hallpike, and 30% of patients reporting a flu-like symptom before acquiring the disorder. The most common causes are viral infections, often resulting from systemic viral infections or bacterial labyrinthitis. Here we presented a rare case of acute vestibular neuritis after the adenoviral vector-based COVID-19 vaccination. A 51-year-old male pilot awoke early in the morning with severe vertigo, nausea, and vomiting after receiving the first dose of the ChAdOx1 nCoV-19 vaccine 11 days ago...
