Filter by:Vertigo, dizziness and control postural disturbance are one of the most disabling symptoms in Multiple Sclerosis. These could be caused by a peripheral or central vestibular disorder. Although, central vestibular damage is more prevalent, peripheral vestibular disturbance aetiology is significantly common in this disease. Within peripheral vestibulopathy, benign paroxysmal positional vertigo is the most common syndrome. Impairments of posterior semi-circular canals in benign paroxysmal positional vertigo represent among the 60-90 % of the cases. Gold standard treatment in this syndrome is the canalith repositioning procedure, called Epley manoeuvre. This manoeuvre has been deeply investigated in previous studies for participants who only suffer from benign paroxysmal positional vertigo. Any randomized clinical trials have been carried out to assess the effectiveness of Epley manoeuvre. However, a retrospective research and a case study reported encouraging results for the resolution of posterior semi-circular canal benign paroxysmal positional vertigo, through the Epley manoeuvre. The main objective of the study is to assess the effectiveness of the Epley Manoeuvre for the improvement of the benign paroxysmal positional vertigo of participants with multiple sclerosis, compared to a passive control group.
The effectiveness of convectional vestibular training for balance and dizziness rehabilitation in people with multiple sclerosis has been recently demonstrated in a meta-analysis by this research team (doi: 10.3390/jcm9020590). Furthermore, non-immersive virtual reality-based environments seem to be useful for balance and gait rehabilitation in this population (doi: 10.1177/0269215518768084). However, nothing is known about the feasibility and effectiveness of immersive virtual reality-based rehabilitation in people with multiple sclerosis. The primary aim of this research is to determine the feasibility, safety and effectiveness of an immersive virtual reality-based vestibular training for dizziness, balance and fatigue rehabilitation, compared to conventional vestibular training.
Patients hospitalized at the rehabilitation department at the hospital will fill a questionnaire regarding dizziness and ear diseases, and the Dizziness Handicap Inventory, and then will be examined by an ENT physician, followed by a video Head Impulse Test (vHIT) study.
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.
The score on the Dizziness Handicap Inventory (short version) before and after hearing aid fitting and usage will be compared
A total of 400 participants will be recruited: 200 patients with suspected OSAS will be recruited from the sleep clinic (OSAS group), 100 patients diagnosed with dizziness will be recruited from the ENT clinic (Dizziness group). In addition, 100 patients with no dizziness and no evidence for OSAS will be recruited from both the sleep clinic and the ENT clinic (controls). Informed consents will be completed by all participants. ). In order to assess the effect of treatment of OSAS on dizziness -patients with the diagnosis of OSAS will complete validated questionnaires regarding sleep, dizziness and eustachian tube function 3 months following initiation of treatment with CPAP
This is a prospective, multicenter, randomized, double-blinded, placebo-controlled, parallel-group, clinical trial to explore the effectiveness of an herbal medication, Gongjin-dan (GJD) for chronic dizziness (Ménière disease, psychogenic dizziness, or dizziness of unknown cause), identified as liver-deficiency pattern/syndrome, and assessed with Dizziness Handicap Inventory (DHI) ≥ 24 at baseline. Participants will be randomized and allocated to either GJD or placebo group with 1:1 ratio and orally administered GJD or placebo pills once a day for 8 weeks. For collecting data for cost-effectiveness analysis, the participants will be followed up to 12 months from randomization.
The purpose of this study is to evaluate the efficacy of a manualised, multimodal group psychotherapy, based on integrative psychotherapy (IPT) and tailored to somatoform vertigo/dizziness (SVD) subgroups of mental disorders, compared to self-help groups (SHGs) in patients with SVD. The investigators hypothesise that patients who received IPT will demonstrate greater improvement concerning their vertigo-related handicap compared to patients from the SHGs. The investigators will also analyse the cost-effectiveness of experimental and control intervention.
