Benign Paroxysmal Positional Vertigo (BPPV) is the most frequent cause of vertigo of peripheral vestibular origin with life time incidence of 2.4%. BPPV is characterized by bouts of acute whirling vertigo lasting less than one minute provoked by changes in head position in relation to the gravitational vector. The vertigo is accompanied by typical rotational or horizontal nystagmus that is often demonstrated by the Dix-Hallpike maneuver and less frequently by testing for positi...
Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder in adults and the treatment of choice is by particle repositioning manoeuvres (PRM). This study aims to compare the treatment efficacy of two home-based exercises, self-Epley manoeuvre (SEM) and Brandt-Daroff exercise (BDE) in patients with posterior canal BPPV based on vertigo resolution, reduction of vertigo intensity, the Dizziness Handicap Inventory scores and the conversion of a positive to ...
Do migrainous vertigo patients have more pathology in their vestibular system than migraine patients without vertigo? The aim of this study is to compare the vestibular system of migraine patients with and without vertigo in the symptom-free period by vestibular function tests, videonystagmography, vestibular evoked myogenic potentials, and subjective visual vertical.
The study evaluates a theory-based educational intervention and implementation strategy on the use of the Dix-Hallpike test (DHT) and Canalith Repositioning Maneuver (CRM) in a community Emergency Department (ED) setting. The DHT and CRM are used to diagnose and treat Benign Paroxysmal Positional Vertigo (BPPV).
To lower the threshold for clinical application by reducing the testing time for recording vestibular-evoked myogenic potentials (VEMPs), we evaluated whether a simultaneous recording of ocular and cervical VEMPs after unilateral or bilateral stimulation can be achieved without a loss in diagnostic sensitivity.
The standard treatment of posterior semicircular canal benign paroxysmal positional vertigo is the canalith repositioning procedure or the Epley maneuver. Based on the present literature, there is controversy on the efficacy of post-maneuver postural restrictions.The aim of this study was to conduct a randomized controlled trial to compare the treatment efficacy of post-maneuver postural restriction with CRP alone in patients with posterior semicircular canal benign paroxysmal ...
The vestibular system in the inner year is an important system in the body which is responsible for balance. In addition, there is evidence that the vestibular system plays a role in maintaining blood pressure while changing body position, such as moving from lying down in bed to sitting. Dysfunction of the vestibular system may affect the ability to maintain blood pressure, therefore the aim of this study is to assess if a specific problem in the vestibular system (Benign Paro...
The propose of this study is to compare two methods of physical treatment for benign paroxysmal positional vertigo, by evaluating treatment effects on postural stability. The trail design is a double blinded randomized controlled trail, with each patient going through three evaluations: before treatment, 1 week after treatment and 60 days after treatment.
The bioelectrical responses of muscle, evoked by sound, obtained with a device considered the gold standard (widely used in clinics and hospitals) are similar to those obtained with a new device developed
The purpose of this study was to compare the immediate efficacies of each treatment maneuvers in treatment of horizontal canal benign paroxysmal positional vertigo (HC-BPPV).
The purpose of this study is to determine the relative short- and long-term efficacy of several physical treatment paradigms commonly employed for the treatment of benign paroxysmal positional vertigo (BPPV), including the Epley maneuver, the Semont maneuver, the Brandt-Daroff exercises and nonspecific vestibular habituation exercises. These procedures involve exercises and head manipulations. Vertigo intensity and frequency, the presence/absence of slow-phase eye movements, th...
To investigate which treatment option (reposition maneuver) with the TRV chair that is the most effective in patients diagnosed with benign paroxysmal positional vertigo (BPPV). Subtypes of BPPV will be examined after randomization to specific treatments.
This study is being done because the investigators would like to know how effective the Liberatory maneuver is in treating benign paroxysmal positional vertigo (BPPV).
Benign paroxysmal positional vertigo (BPPV) is one of the most common types of vertigo, especially in elderly. Therefore the investigators have set the goal to evaluate the prevalence of BPPV and its therapy using the Rotundum device in elderly living in retirement homes. Furthermore the investigators use a questionnaire to evaluate possible predictive signs to improve the diagnosis of this disease.
"Test-Retest Reliability of ocular vestibular evoked myogenic potentials (oVEMPs) across different electrode montages." The purpose of this project is to compare the response characteristics of the ocular vestibular evoked myogenic potential in patients grouped by decade (i.e. 20's-90's) using two different recording montages and two different stimulus types (i.e. air and bone conducted sound). The long-term goal is to increase the sensitivity and specificity of the oVEMP when...
Benign paroxysmal positional vertigo (BPPV) represents the most common cause of labyrinthine vertigo with a lifetime prevalence of 2.4 percent. Onset is most common between the fifth and seventh decades of life. The disease can be a major handicap for the affected patient, and causes a great expense for society. The traditional manual treatment with repositioning maneuvers has greatly improved the possibilities for treatment of BPPV the last decade. However some patients are st...
The benign paroxysmal positional vertigo (BPPV) is a type of peripheral vertigo characterized by the accumulation of otoliths debris, which are particles resulted from the condensation of endolymph in the inner ducts of semicircular canals (duct lithiasis or canalithiasis). In order to detect the BPPV, a simple test is utilized. The Dix-Hallpike test consists in lay the individual in a quick change in the position of the head. The maneuver is performed, essentially, towards the...
Recently, new clinical testing of saccular and utricular function have been developed and validated, the so-called vestibular-evoked myogenic potentials - VEMP (Brantberg et al. 2009, Cornell et al. 2009, Curthoys 2010, Manzari et al. 2012). Among them, the cervical VEMP (cVEMP) are short-latency electromyographic (EMG) modulations of the contracted sternocleidomastoid muscles in responses to vibration applied on the forehead. The clinical literature suggests that cVEMP are alm...
Myasthenia gravis is an autoimmune disorder of neuromuscular transmission, characterized by fluctuating muscle weakness and fatigability. In isolated ocular myasthenia, when only the extraocular muscles are involved, most common ancillary tests, such as acetylcholine receptor autoantibodies and repetitive nerve stimulation, are often negative. A simple, quick and non-invasive test for ocular myasthenia based on ocular vestibular evoked myogenic potentials (oVEMP) was recently ...
Nasopharyngeal carcinoma (NPC) is usually treated with chemoradiotherapy. While the effects of this treatment on cochlear function is well characterized, its effect on vestibular function is not well studied. In this study the investigators will study the vestibular function of 50 patients undergoing chemoradiotherapy for NPC both before and after treatment in order to better define its effects. All patients will undergo a validated questionnaire (dizziness handicap index), ...
The investigators are training a group of four pediatric Sports Medicine providers in BPPV maneuvers. All four providers will be trained in the diagnostic maneuvers, and two will be randomly selected to also be trained in the treatment maneuvers. The providers will be encouraged to use the diagnostic maneuvers on all new concussion patients whose initial visit is within 28 days of their injury. They will complete a survey at the start and end of the study to determine if they t...
Surgical removal of vestibular schwannoma causes acute vestibular symptoms, including postoperative vertigo and oscilopsia due to nystagmus. In general, the dominant symptom postoperatively is vertigo. Preoperative chemical vestibular ablation can reduce vestibular symptoms postoperatively.
Patients with multiple sclerosis (MS) might develop dizziness or vertigo as a first manifestation or during the course of the illness. Many patients with MS experience chronic or intermittent dizziness. Acute symptoms of dizziness or vertigo in MS fall into two categories; acute vestibular syndrome (AVS) and positional vertigo. Vestibular disorder due to MS decreases whole body dynamic postural control and causes many functional limitations as limitations in ambulation, dynami...
