Filter by:The purpose of this study was to compare the immediate efficacies of each treatment maneuvers in treatment of geotorpic horizontal canal benign paroxysmal positional vertigo (HC-BPPV).
The purpose of this study was to test the feasibility and effectiveness of a novel exercise intervention for individuals who live with multiple sclerosis (MS).
The eye movements of vergence allow binocular vision whatever the viewing distance or the body movements are and the perception of depth. Vergence dysfunction can lead to erroneous visual sensation of movements. In our daily life using screens (computer, game boys..) is increasing and this approach heavily the ocular vergence and can lead to symptoms if oculomotor and accommodative systems are dysfunctioning (Ped. Neurology 2000). Not knowing this pathology lead to inappropriate and expensive prescription CT scan or NMR. To evaluate the vergence performances just evaluation in static condition is currently available in ophthalmology departments. The CNRS laboratory (IRIS, FRE 3154) adapted a technic of eye movement recording to study ocular vergence in dynamic condition.
Rotational maneuver is a vestibular rehabilitation method, performed in a supervised manner. Using a rotating chair, subjects are rotated towards the opposite direction of dominant side in order to inhibit this side and simultaneously, stimulate the subordinate side. We propose that the rehabilitative effect is the result of a decrease in the vestibular imbalance, mainly due to a decrease in the response of the dominant vestibular side. Previously, we have shown the short-term effects of this maneuver on patients with recent onset vestibular imbalance. In the present study, we investigated the long-term effects of the rotational maneuver in patients with a history of peripheral vestibular vertigo for at least one year, originally confirmed by clinical tests. Our results show a significant improvement which lasted for >4 weeks after the end of rehabilitation (i.e., the last time tested). Moreover, there seems to be a relationship between the decrease in DP values and a decrease in subjective symptoms. We propose that this maneuver can be used as an effective method for both short- and long-term rehabilitation.
The purpose of this project is to determine the effects of mild traumatic brain injury and blast exposure on the inner ear balance and central nervous systems.
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 positional nystagmus. BPPV pathogenesis is currently explained by the fall of otoconia (calcium-carbonate crystals) or otoconial debris from the tectorial membrane of the otolithic organs into the dependant semicircular canals (canalithiasis) or adherence of such particles to the semicircular canal's cupula (cupulithiasis). Under these circumstances, the semicircular canal which normally responds only to angular velocity and acceleration is stimulated by gravity. Otoconial remnants as free floating particles inside the semicircular canal arms or attached to the cupula have been observed by few investigators. Although the presence of such particles explains most characteristics of the positioning nystagmus described in BPPV, it does not account for the dizziness and disequilibrium which are described by many patients even without changes in head position and the continuation of such symptoms after successful treatment of BPPV as evidenced by the resolution of positional vertigo and nystagmus. The study hypothesis is that otolithic pathology is an important component in the pathogenesis of BPPV explaining these symptoms, BPPV recurrence, and the refractoriness of some BPPV cases to the vastly employed particles repositioning treatments. In the present study the Vestibular Evoked Myogenic Potentials (VEMP) testing would be employed to measure the function of one of the otolithic organs - the saccule. The study objectives are: 1. To investigate possible malfunction of the saccule in patients suffering from BPPV. 2. To look for association between saccular pathology and BPPV recurrence and between such pathology and BPPV treatment failure. 3. To study possible relation between saccular pathology and continuation of dizziness and disequilibrium despite the resolution of positional vertigo.
Dizziness has been identified as a risk factor for fall and vestibular asymmetry has been found among patients with fall-related wrist fractures as well as among patients with hip-fracture. Since wrist fracture is a risk factor for hip-fracture, much effort is focused on preventing falls for risk-groups. Therefore, it would be interesting to find out if it is possible to influence vestibular asymmetry with vestibular rehabilitation. The aim of this study is therefore to find out if vestibular rehabilitation can have any effect on vestibular function among patients with fall-related wrist fracture.
The goal of this project is to provide individuals that have a balance deficit with a device that will give them signals that they can feel (vibrations) in order to help them maintain a correct sense of balance and perception of place in the environment.
The investigators primary aim is to test whether or not provision of the self-help booklet teaching VR exercises, with up to one hour of telephone support from a vestibular therapist, will be more effective than routine care in reducing symptoms in dizzy patients in primary care. The investigators will also explore the extent to which patients may benefit from the self-help booklet without support. The investigators will determine whether these models of delivery are less costly than routine care of dizzy patients, as they should reduce the number of patients seeking referral to secondary care for unnecessary assessments.
The aim of this study is to assess if early supported vestibular rehabilitation can reduce dizziness and improve daily life activities in patients with acute vestibular injury. The study question is: Does early supported vestibular rehabilitation have an additional effect on dizziness symptoms and daily life functions compared to standard treatment?
