Filter by:Hearing-impaired children are at risk for a vestibular impairment, as the auditory and vestibular end organs are closely related. Although this can compromise a child's development on many levels, vestibular testing is not routinely performed in this vulnerable group. This project aims to give each congenitally hearing-impaired child in Flanders (Belgium) access to a basic vestibular screening at a young age and set an example for other regions worldwide.
Acute onset vertigo is common and entails much suffering with persisting symptoms at 3 months after onset in up to half of those afflicted. Vestibular rehabilitation to aid recovery is not readily available. The purpose of this study is to investigate the effects on vertigo symptoms of a 6-week online vestibular rehabilitation tool compared with standard care (written instructions leaflet) after acute onset vertigo.
This study was planned to investigate whether there is a visual-spatial perception disorder in individuals with idiopathic scoliosis and also to reveal its dependent/independent relationship with vestibular dysfunction.
Dizziness, loss of balance, and unsteadiness of gait are common symptoms reported by Emergency Department (ED) patients. The incidence of acute vestibular syndrome (AVS) is increasing and reaches 2-4% of ED visits. In the ED of the Paris Saint Joseph Hospital Group, its incidence was 5% during the year 2019 and 2% during the year 2020 (COVID-19 pandemic period). Emergency medicine is based on a dichotomous principle for any acute pathology in the initial phase. For AVS, the diagnostic dilemma for emergency physicians is usually to differentiate a benign vestibular cause from a potentially serious cerebral cause such as ischemic stroke of the vertebro-basilar territory. The majority of AVS are related to acute vestibulopathies, yet it is necessary to recognize and distinguish a benign paroxysmal positional vertigo (BPPV) from a vestibular neuritis, a vestibular migraine, or a labyrinthine hydrops, to exclude with certainty a cerebral involvement. However, posterior fossa strokes mimic 5% of BPPV and 25% of vestibular neuritis. Among these strokes, about 20% are therefore revealed by a VAS without associated localizing neurological sign. In the absence of a clear neurological sign, the emergency physician must therefore decide whether to treat the patient as an outpatient when he or she suspects a AVS of "peripheral" origin (otolaryngology), or as an inpatient when he or she suspects a "central" origin, in particular a stroke.
The goal of this study is to improve the vestibular implant's ability to reduce the vestibular-dependent perceptual, postural, and visual symptoms that affect patients with severe peripheral vestibular damage. The long-term research plan is focused on exploring the three questions which must be answered to assess the clinical utility of a vestibular implant (VI) in vestibulopathic patients - i) how can information transfer from the VI sensors to the brain be optimized; ii) how does the three-dimensional angular velocity information provided by the VI interact in the brain with other sensorimotor (vision, otolith, efferent) signals; and iii) how effectively does the VI alleviate the behavioral deficits and subjective symptoms experienced by patients with severe vestibular damage. The current study will be used to focus on two key subsets of these questions. Over one year, the investigators will study approximately 5 patients who have severe bilateral vestibular damage and functioning VI's, which will focus on aim 1: how the angular velocity information sensed by the VI can be optimally transferred to the brain; and aim 2: how effectively the VI improves the clinical status of vestibulopathic patients when they receive acute and sub-acute (3 days) motion-modulated stimulation. In sum, the investigators aim to improve the efficacy of the VI in human subjects by developing new knowledge about how the brain processes motion cues provided by the VI and correlating this information with behavioral outcomes.
14.44% of the Spanish population is over 70 years old and Aging as a normal process is characterized by gradual modifications in the physiological functions of the different systems, so that as age progresses, deterioration can lead to imbalances and alterations in health that cause diseases or traumatic processes. Within these processes, vestibular loss occurs normally in the face of healthy aging and, encompassed within this progressive dysfunction, various symptoms such as dizziness, imbalances, facial and limb weakness, confusion or headache may occur. Functional status is the best indicator of the overall health status of the elderly person. Identifying these indicators as soon as possible is the best way to prevent functional decline and promote active aging and life expectancy free of disability. For this reason, there are strategies that are currently a priority in health systems. The special COVID circumstances eliminate the possibility of group work and invite the realization at home or individually of workshops or collective exercises In the field of physiotherapy, vestibular exercises have shown efficacy for improving balance and reducing the risk of falls in cognitively intact people without vestibular impairment, being a specific approach to vestibular rehabilitation for the reduction of dizziness and imbalances , as it facilitates the compensation of the Central Nervous System. physiotherapy intervention has been shown in various studies to be effective in improving balance and reducing the risk of falls in older people. Also considering that the control of body balance in the elderly depends not only on the vestibular system, but also on the correlations between all the other systems, it seems interesting to add exercises with multiple components, since it would add effects of improvement in functional independence of people greater for daily activities and control of body balance. Therapeutic physical exercise is an effective non-pharmacological strategy to improve the functional condition of the elderly and although it is known that there are various exercise modalities that improve physical function and quality of life, The Clinical Practice Guidelines emphasize the importance of multicomponent / multimodal exercise for this population group
This project will investigate the role of noise in the vestibular system, and in particular its effects on the variability (precision) of vestibular-mediated behaviors. The investigators will study vestibular precision in normal subjects and patients with peripheral vestibular damage, and will investigate its potential plasticity. The goals are to develop a better understanding of the role noise plays in the vestibular system in normal and pathologic populations, and to determine if the brain can learn to improve signal recognition within its inherently noisy neural environment, which would result in improved behavioral precision.
The purposes of this research are to 1) utilize virtual reality (VR) to evaluate the exercise dose required to improve symptoms in those with vestibular (dizziness) disorders, 2) compare VR vestibular exercises to standard exercises, and 3) compare exercise performance outcomes to healthy controls without vestibular disorders. Even though more than 35% of those over 40, and ~50% of those who have had concussion have such symptoms, the dose of specific exercises targeted to improve symptoms is not well defined. In this study, the investigators will use a wireless VR device to measure key parameters and response to exercise. Another advantage of the VR device is the ability to control what the individual can see while performing the exercise. In normal daily life, moving objects and distracting backgrounds can make vestibular exercise too uncomfortable to perform. Using these methods, the investigators aim to determine the appropriate type and amount of exercise required for symptom improvement. This study will also compare the effectiveness of performing exercises in the virtual reality environment to standard physical therapy and to healthy persons without history of vestibular disorders. Three categories of vestibular disorders will be investigated with an instrumented and usual therapy group of 1) Unilateral hypofunction, 2) bilateral hypofunction, and 3) post-concussion.
Vestibular information is important in establishing a child's static and dynamic postural control. Any vestibular deficit can have major consequences on development, spatial cognition and quality of life. In order to interact with the world around us, we must simultaneously integrate different sources of sensory informations (vision, hearing, perception of the body...). The brain integrates these different sensory components to form a unified and coherent perception: this is multisensory integration. Multisensory integration has been studied using virtual reality in adults, in the "spatial orientation" team of the Center for Integrative Neurosciences and Cognition. These experiments were carried out on healthy subjects and in weightless situations (international space station or parabolic flight). However, no protocol has been developed in children or in subjects with vestibular deficit. Virtual reality is interesting for developing such a protocol because it creates multisensory stimulation capable of promoting visual and proprioceptive compensation of the vestibular deficit. It induces an immersion of the patient in a virtual spatial and temporal environment difficult to carry out with traditional vestibular rehabilitation techniques. Its main advantage is that it is a fun and safe interactive diagnostic and therapeutic tool, which is particularly suitable for children. Being able to modulate certain sensory information using virtual reality, in children without vestibular function deficit and in children with vestibular function deficit, will make it possible to better understand the role of the vestibule in the construction of the self in relation to space and environment. In addition to the scientific aspect, the diagnostic and therapeutic benefits are potentially numerous. The objective of the study is to determine a reliable, well-tolerated and age-appropriate virtual reality protocol in children without vestibular deficit and in children with chronic vestibular deficit, making it possible to study the hand-eye coordination.
Animal models of Kabuki syndrome have showed a reversal of the cognitive phenotype with ketogenic diet. Modified Atkins diet is safer and easier tolerated than full ketogenic diet and still has the histone deacetylase inhibition believed to be responsible for the cognitive improvement. This study aims to examine a small number of adults with Kabuki syndrome before and after 12 weeks on a modified Atkins diet to determine if there is any cognitive improvement and if the diet can be tolerated.
