Virtual Reality Epley Maneuver System (VREMS) for Treatment of Benign Paroxysmal Positional Vertigo...

BPPVVertigo1 more

Background and Rationale: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, affecting 2.4% of the general population and 30% of those over 70 years old. The main symptom is the perceived sensation of movement of the surrounding or self, without actual such movement, triggered by changes in position (positional vertigo). It can be dangerous as repetitive symptoms can lead to falls and depression, particularly in the elderly. Additionally, at least half of those with initial symptoms of BPPV will have ongoing symptoms if not treated. The Epley maneuver is a particle-repositioning maneuver that is used to treat posterior semicircular canal BPPV, the most common type of BPPV, after a diagnosis has been made on physical examination. In-office administration of the Epley maneuver by a specialist yields a 90% success rate at treating the condition; however, at-home administration is much less successful. In a previous paper we demonstrated the development and face validation of a Virtual Reality Epley Maneuver System (VREMS) for performing the Epley maneuver correctly. In this study we aim to apply VREMS treatment in patients who have been diagnosed with BPPV. Research Question and Objectives: PICO (Patient/Population Intervention Compare Outcome): In adult patients diagnosed with posterior canal BPPV by a specialist, does VREMS, as compared to self-performed Epley maneuver using an instructional handout (IH) result in improved or resolved symptoms? Methods: Vertigo patients referred to the Neurovestibular Clinic will be evaluated by an Ear, Nose and Throat (ENT) specialist. Those who are diagnosed with posterior canal BPPV after history and physical examination including the Dix-Hallpike test will be approached to be recruited into the study. Patients who consent to participating in the study will be allocated to either the VREMS cohort or the control cohort. Those in the control cohort will be provided an instructional handout (IH) to help them perform the Epley maneuver. Patients in the VREMS cohort will be provided with the VREMS device, which will help guide them through the Epley maneuver in a virtual reality environment. All participants will be asked to rate the severity of their symptoms before undergoing the Epley maneuver. Subsequently, patients will be supervised as they perform the Epley maneuver - VREMS assisted or based on reading the IH. In both groups, once the patient has performed the Epley maneuver (whether with VREMS assistance or with the IH), they will be asked to rate their symptom severity after undergoing the Epley maneuver. All patients will also be asked to complete the NASA Task Load Index (NASA-TLX) to gauge their perceived mental workload. They will also be given an opportunity to give free-text feedback. For any patient with residual BPPV symptoms following Epley maneuver with VREMS or IH, the ENT specialist/vestibular physiotherapist will perform the Epley maneuver to ensure resolution of symptoms if possible prior to discharge from the clinic. The primary outcome of the study will be the improvement in and resolution of BPPV symptoms with VREMS use as compared to IH. Secondary outcome will be mental workload in each of the study arms.

Visual Feedback Goggle for Positional Vertigo Treatment

Positional VertigoVertigo

Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common causes of vertigo and the most common vestibular disorder of the inner ear. BPPV is the result of small free-floating particles (canaliths) in the posterior semicircular canals where they aggravate the sensory apparatus and induce sudden and severe attacks of vertigo when the head is turned into certain positions. The treatment of BPPV was revolutionized by the introduction of the Epley maneuver, a sequence of head movements that use gravity to reposition the canaliths within the inner ear. The Epley maneuver provides prompt relief from vertigo in approximately 80% of patients. The innovation, the Vertigone goggle, provides both physician and patient with visual feedback to guide them through an accurate Epley maneuver. This changes the current treatment paradigm for BPPV, greatly increasing the availability of the maneuver to non-specialist physicians, nurse practitioners, physician's assistants and physical therapists. The device is designed so that the patient with recurrent vertigo can use the goggle to treat BPPV at home. The goggle is currently a pre-market prototype. The hypothesis for the study is that accuracy in the performance of the Epley maneuver correlates with improved clinical resolution of vertigo in BPPV patients. If the hypothesis is true, then there is a clear case for the utility of the visual feedback provided by the VertiGONE goggle in performing the maneuver.

Validation of an iPhone-based Event Recorder for Arrhythmia Detection

ArrhythmiaPalpitations1 more

In this study, we will evaluate the diagnostic yield of the new AliveCor device versus a 14 day event monitor with the use of both devices simultaneously. We will also examine by means of a questionnaire the compliance, ease of use and patient satisfaction for each device. Hypothesis: The AliveCor monitor will be non-inferior to the 14 day event monitor with respect to diagnosis of the arrhythmia responsible for a patient's symptoms. The AliveCor monitor will have better compliance and acceptability compared to the 14 day event monitor, and thus there will be a greater number of days with recordings from the AliveCor monitor.

Effectiveness of Betaserc® (Betahistine Dihydrochloride) in Patients With Vestibular Vertigo in...

Vertigo

The purposes of this international post-marketing observational program is to investigate effectiveness of betahistine dihydrochloride (Betaserc®) tablets and assess the course of vestibular vertigo after treatment discontinuation in population of Russia and Ukraine outpatients suffering from vestibular vertigo in pragmatic clinical settings. Exploratory analyses of results from both participating countries may be expected to provide insights about the subjective circumstances of vestibular vertigo patients in a wider than usual range of gender, underlying ICD-10 diagnosis, national and cultural situations.

The U.S. Embryologist Fatigue Study

FatigueStress13 more

The purpose of the study is to determine physical and mental health issues of U.S. embryologists related to their occupational characteristics, and how workplace fatigue and burnout may affect their quality of life, cynicism, interactions with patients, attention to detail, and lead to human error, the cause of the most severe IVF incidents that often make headlines and result in costly litigation. It will also correlate how the current manual workflows contribute to these health issues, and what measures can be taken to improve both working conditions and embryologists' health, and, therefore, improve patient care.

Serum Levels of Otolin-1 and Vitamin D in Pre- and Post-treatments of BPPV

Benign Paroxysmal Positional Vertigo

BPPV is the most common cause of vertigo. The pathophysiology of BPPV has not been cleared, several studies show that symptoms are caused by the displacement of otoconia from the macula of the utricle into the semicircular canals. These calcium carbonate particles then stimulate non-physiological movement of the endolymph leading to a false sensation of angular acceleration. Biomarkers represent measurable products of biological processes, thus making an assessment of those processes more practical. Biomarkers in circulation are powerful indicators of normal and pathological biological processes, as well as, responses to pharmacological treatments. The inner ear-inclusive protein that has been published included Otolin-1, Otoconin-90/95, Prestin, Otoancorin, Otogelin, α-tectorin, β-tectorin and Cochlin.
