Stellate ganglion block (SGB) has been the alternative treatment of Meniere's disease for years. However, objective evidence of the effect of SGB was still lack. The investigators conducted a randomized controlled study to examine the immediate effects of SGB in SP/AP of electrocochleography (ECoG).
Western University of Health Sciences is seeking men and women to participate in a study on the effectiveness of Osteopathic Manipulative Treatment (OMT) and Vestibular Rehabilitation Therapy (VRT) in patients with vertigo. The purpose of this study is to examine the efficacy of OMT in the treatment of individuals with vertigo, alone and in combination with Vestibular Rehabilitation Therapy (VRT). Because of the health care costs associated with vertigo, the cost effectiveness of OMT and VRT will also be examined.
The diagnosis and management of acute vertigo and dizziness is most of the time an easy task for the general practitioner. However, following an acute vestibular disorder and very often with no any overt cause, a considerable number of patients complain on chronic dizziness and subjective disturbance of balance despite normal clinical and laboratory tests. Patients describe that perceptual visual stimulus provoke or aggravate their symptoms that are frequently accompanied by anxiety. These cases have been described in the medical literature as Phobic Postural Vertigo, Visual Vertigo, Chronic Subjective Dizziness and Motion and Space Discomfort (2,3,4,5). Treatment of these conditions includes physical therapy (similar to vestibular rehabilitation exercises) and anti-anxiety or anti-depressant agents such as benzodiazepines and SSRI, however, the effectiveness of these approaches is debatable. Because visual stimuli play a crucial role in space orientation and motion perception, it is reasonable to hypothesize that certain visual stabilizing signals applied on the peripheral visual field (that is involved mainly in the perception of motion) could be of help in patients suffering from dizziness. This is the rationale of a new technology (SMB- Senso Mental Balance Technology) developed to alleviate the feelings of dizziness. Trial is conducted in Meir Medical Center, Israel.

The alternate binaural bithermal caloric test (ABBT) is a well established examination in the evaluation of the dizzy patient. ABBT is useful in detecting the side of peripheral vestibulopathy by stimulating each ear separately, it contributes to the diagnosis of bilateral vestibular involvement when all responses to cold and warm stimuli are reduced, and adds to the differentiation of peripheral from central vestibular involvement by measuring the fixation-induced inhibition of the caloric response. In spite of these benefits, ABBT is the most time-consuming part of the electronystagmography/Videonystagmography (ENG/VNG) test battery, and frequently causes significant inconvenience to the patient due to the repeated extreme vestibular stimuli. The head impulse test (HIT) assesses vestibular function by brisk, passive rotations of the head in the plane of the examined semicircular canals. Whenever the vestibulo-ocular reflex (VOR) is deficient, this maneuver would produce catch-up saccades aiming to the re-fixation of the eyes on the target. Hence, both residual VOR and catch-up saccades act synergistically to stabilize gaze. The HIT requires only several minutes and might cause minimal discomfort only. The study hypothesis is that the HIT recorded by standard VNG equipment of the VNG system would provide diagnostic information on the side of vestibular involvement matching that of the ABBT.
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).
Patients with dizziness presently undergo physical therapy rehabilitation. Our study will study whether Wii Balance Board made by Nintendo Inc. will be helpful in patients with dizziness. They will undergo dizziness evaluation to quantify their dizziness.
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 specific aim of this proposed pilot study is to compare two standardized processes (paper and electronic) to deliver a customized MedlinePlus health information prescription.
