Filter by:The purpose of this study is to develop and validate methods to use hearing aids equipped with embedded sensors and artificial intelligence to assist in the assessment of fall risk and in the implementation of interventions aimed at reducing the risk of falling, as well as to improve speech intelligibility in quiet and in background noise, track physical activity, and social engagement. The investigators hope is that the knowledge that is generated through this study will ultimately translate to the clinical setting and will help reduce the likelihood that individuals experience a fall, and improve the quality of hearing in individuals who wear hearing aids.
Depersonalization-derealization (DD) disorders are a clinical phenomenon characterized by feeling disconnected or detached from one's self. Individuals may report feeling as if they are an outside observer of their own thoughts or body, and often report feeling a loss of control over their thoughts or actions. Several scales have been developed to measure DD, and the Cambridge Depersonalization Scale (CDS) appears to be the most relevant and consistent to characterize the clinical symptoms of these disorders as well as their duration and frequency. This scale, originally written in English, must be translated and validated according to standardized methods that include testing steps patients with dizziness and in individuals with no vestibular disorder. Persistent postural-perceptual dizziness (PPPD) is a chronic, persistent vestibular syndrome generally preceded by acute vestibular disorders. The main symptoms are rotational dizziness, unsteadiness and / or non-rotating dizziness that are exacerbated by upright posture, walking, active or passive movement, and exposure to moving visual stimuli or complex visual patterns. To help diagnose this syndrome, a questionnaire was developed in Japan in 2019, the Niigata questionnaire, however no French version has yet been validated. Similarly, this scale needs to be validated in patient with PPPD and in control populations. The main objective of this study is to validate the French translation of these two scales, the CDS questionnaire and the Niigata PPPD questionnaire, according to standard methods (forward translation, back translation, consensus).
By evaluating the balance, gait and cognitive functions of the elderly patients with vertigo, the relevant functional disorders of the elderly patients with vertigo were clarified, and the functional disorders of the elderly patients with vertigo were improved through the new rehabilitation intervention.
Incidence: Dizziness or vertigo is a very prevalent complaint in the general population, and a common reason for seeking medical attention. In Denmark, 20-30 % have experienced dizziness/vertigo to a degree that has led to disability, sick leave, or medical contact(1). In the United States, dizziness is estimated to account for partly 2.6-4.4 million visits to emergency departments (EDs) each year, partly 4 % of main symptoms in patients admitted to EDs (2). In Germany, the estimated prevalence of dizziness is 20-30 % with an annual incidence about 11 % (3). Terminology and definition: Dizziness or vertigo is not a disease itself but rather a symptom of various underlying disorders. Thus, vestibular, neurological, cardiovascular, metabolic, and psychiatric diseases may be associated with dizziness/vertigo as well as medical side effects. Patients (and professionals) often use the two terms dizziness and vertigo synonymously, which may cause some confusion in the choice of diagnostics. Vertigo is characteristic for vestibular disorders and is defined as sensation of self-motion when no self-motion occurs, or sensation of distorted self-motion during an otherwise normal head movement, whereas dizziness is a feeling of more general unsteadiness. 1. Is implementation of HINTS and v-HIT in an ED able to reduce the number of undiagnosed and misdiagnosed cases of acute onset vertigo as well as diagnostic delay ? 2. What are the effects of immediate and systematic balance training in case of acute vestibular diseases ? 3. What is the cost-effectiveness of implementation of HINTS and v-HIT as up front diagnostics, and systematic balance training in patients with acute vestibular diseases ?
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.
Despite the growing research on Benign Paroxysmal Positioning Vertigo (BPPV), the impact and treatment efficacy on balance, physical activity (and consequently) frailty in elderly is lacking. Also, the added value of the video Head Impulse Test (vHIT) in this population has never been studied before. With insights gained from this research, we hope to contribute to an efficient treatment of BPPV in this growing population and to minimize its impact and healthcare burden.
BPPV is a benign condition of the balance organ, localized in the inner ear, in which calcium crystals loosen up and move freely in the endolymphatic fluid of the inner ear (more specifically in the semi-circular canals). During certain posture changes or head movements, these moving calcium crystals cause dizziness and balance problems. The general objective of the study is to evaluate the impact of BPPV on the balance of older adults in nursing homes. For this purpose, we will compare the balance of residents with BPPV with residents without BPPV. Furthermore, we will identify the impact of treatment on balance problems and fall risk in older adults in nursing homes.
Cervical reflex vertigo is a non-common cause of vertigo, caused by decreased afferent input from the upper three cervical segments to vestibular nuclei.
In many patients with an acute unilateral vestibular deafferentiation (uVD) syndrome symptoms are expected to resolve spontaneously because of central compensation. However, more detailed observations have revealed that 29-66 % of uVD patients develop disabling chronic dizziness lasting >1 year after the acute event. Identifying predictors of chronic dizziness would allow patients at high risk to be targeted with personalized therapies to reduce healthcare costs. Therefore, the main objective of this study is to identify predictors of chronic dizziness after an acute uVD. Despite the consensus on the usefulness of physical therapy, incorporation of physical therapy programs in daily management of patients after acute uVD remains troublesome. Therefore, the first objective is to study the effect of the actual level of physical activity in the acute stage on long term (LT) outcome. Recent data show that LT prognosis is more linked to anxiety and somatization traits than to objective vestibular findings. Therefore, the second objective is to study the effect of activities avoidance behavior on LT outcome. As stated above it is questioned whether objective vestibular findings can predict chronicity. However recently the Perez and Rey(PR) score was developed. Therefore, the third objective is to study the effect of early central vestibular compensation as measured by the PR score on LT outcome. In patients with poor central vestibular compensation the remaining sensory cues will need to compensate for the loss of vestibular information. Patients using a visual compensation strategy can become dependent of stable visual cues. Therefore, the fourth objective is to study the effect of visual motion sensitivity on LT outcome. A 2-year prospective cohort study will be performed to study aforementioned risk factors for chronic dizziness. Up to 200 consecutive patients with an acute uVD will be included. Chronic dizziness is indicated by a score >30 on the Dizziness Handicap Inventory (primary outcome) after 6 months. Possible risk factors will be evaluated by using MOX1-activity loggers (objective 1), the Vestibular Activities Avoidance Inventory (objective 2), video Head Impulse Testing including the Perez & Rey score (objective 3), Subjective Visual Vertical test and Rod & Disc test (objective 4). Measurements will be taken in the acute phase and 4, 10, 26 and 52 weeks after the acute event.
In the Chinese Headache and Vertigo Registration Study, patients aged 4-99 years with headache (primary headache and secondary headache such as migraine and tension type headache), vertigo (vertigo diseases such as vestibular migraine) and chronic pain (fibromyalgia and other diseases) were collected. The biomarkers, imaging features, right-to-left shunt of the heart (lung), genetic characteristics, treatment, and outcome (in relation to other diseases) of headache-related diseases were studied, and long-term follow-up was planned.
