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 Paroxysmal Positional Vertigo- BPPV) may cause changes in the interaction between the vestibular system and the cardiovascular system. We assume that patients with this medical condition (BPPV) will have different heart rate parameters in comparison with healthy patients.
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 side in which the patient alleges dizziness in the course of the change in the position of the head. If the individual report vertigo related or no to nystagmus, the test is considered as positive . The osteopathy is a science, which has specific methods of diagnosis and treatment, and has begun to be developed by the physician Andrew Taylor Still at the end of 19th century, which aim is to rebalance the activities of the organism. Accord to the osteopathy science, all the physiological structures in the organism integrating and requires functional and structural harmonization in order to improve the health of the whole body. The main objective of the treatment is to obtain the intertissue mobility, which is considered by osteopathy as a somatic dysfunction, when it is restricted. Samutt confirms that cranial dysfunction of the temporal bones in internal/external rotation may modify the orientation of the semicircular canals, provoking vertigo. Liem propose that the mobilization of the eyeball may be a sensory stimulus of the vestibulo-ocular pathways. For him, maneuvers to the eyeball assists to balance the tonus of extraocular muscles and creates fascial influences on the optic nerve and the oculomotor, and, thus, stimulates the vestibular nuclei. It also suggests that the tension of the cerebellar tentorium and the mobilization of the temporal bones have effects on the structures that composes the vestibule. Thereby, the present work investigated the effect of the cranial osteopathic techniques on the Benign Paroxysmal Positional Vertigo.
Vestibular schwannoma is a benign tumor located on the vestibular nerve. Patient could present dizziness symptoms cause to the tumor, and at least after the treatment by gamaknife radiosurgery or microsurgery resection. Only few studies keep the interest about dizziness symptoms and treatment modality in vestibular schwannoma. In the study dizziness symptoms were compared before and after the treatment of vestibular schwannoma by radiosurgery gammaknife or microsurgery resection. 2 scales were used : dizziness handicap inventory (DHI) and dizziness functionnal scale (AAO).
IRM-DU is a prospective observational single center study conducted in an emergency department to evaluate the impact of a MRI scanner exclusively dedicated to emergency in the clinical management of patients presenting with dizziness or diplopia. The study will compare 2 strategies : after and before availability of a MRI scanner dedicated to emergency. The primary endpoint is the proportion of patients with a diagnosis of stroke confirmed by imaging (MRI or Computed tomography (CT)) in the group "before implementation of the emergency MRI scanner" and the group "after implementation of the emergency MRI scanner". The hypothesis is that the availability of a MRI scanner dedicated to emergency will improve the diagnosis of stroke in patients presenting with dizziness or diplopia, and will reduce Emergency Department stay, hospital stay and hospitalisation costs.
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.
In order to provide information that will improve therapy, the goals of this project are to determine if persons with MS with complaints of dizziness and at risk for falls can improve their balance and vision stability as a result of a bout of specific treatment. This project seeks to do this by conducting an experiment where people with MS are randomly assigned to a group that practices activities known to help improve inner ear function or a group that practices activities known to improve endurance and strength but that should not change inner ear function. Such a comparison will allow us to gain understanding of how the inner ear system is affected in MS and how it responds to treatment.
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 thought the training affected their understanding of BPPV and confidence in managing it, as well as determine any challenges they faced with learning/administering the maneuvers. Additionally, the investigators will determine if the additional training impacts time to recovery from concussion, as well as determine potential risk factors for BPPV in concussion.
Dizziness is a common complaint reported by 30% of people above 65 years of age and by more than 50% of those 90 years of age and older.(1) Age-related decline in vestibular, musculoskeletal, and neurologic performances compounded by a vestibular pathology can result to debilitating physical and psychological consequences. Dizziness is associated with falls,(2) disability (3) and physical inactivity.(4) Walking for endurance is cited as one of the components of vestibular rehabilitation (VR) in the "Clinical Practice Guideline for Peripheral Vestibular Hypofunction".(5) Although walking can offset the avoidance of physical activity from symptom provocation, no direct evidence has been found to support the effect of walking on postural and dynamic stability, function, and participation in people with dizziness. The primary purpose of this study is to evaluate the impact of walking as an exercise component of VR on both primary and secondary vestibular-specific outcome measures. The primary outcomes are mCTSIB, TUG test, DGI, and DHI, while the secondary outcomes are the total number of visits and length of interventions (in weeks). The second purpose is to evaluate whether pedometers increase the adherence of older adults with vestibular issues to a walking program. This will be measured by change in physical activity, as represented by International Physical Activity Questionnaire (IPAQ) Walking Metabolic Equivalent of Task (MET)-minutes/week and IPAQ Total Physical Activity MET-minutes/week scores from the IPAQ short form during the episode of care (admission and discharge) and on four-weeks follow-up compared to those patients who only received instructions to walk without a pedometer. The third purpose of this study is to establish test-retest reliability of the TUG test on older adults with dizziness. Lastly, the fourth purpose of this study to investigate if the TUG, DGI, and mCTSIB are significant and strong predictors of the DHI in older adults with dizziness. Protocol #1365169 "Predictors of Disability in the Older Adults" is being performed to supplement the number of subjects for the fourth objective of this study.
The goal of this study is to evaluate a tactile prosthesis that provide individuals who have demonstrated chronic imbalance with help to maintain a correct sense of orientation with respect to the gravity and improve posture control.
