Introduction: The inner ear vestibular system is essential to balance function. Although hearing loss is well-described and quite common following meningitis, the literature evaluating vestibular function following meningitis is very limited. In particular, information on results of contemporary vestibular function tests, e.g., the video head impulse test (VHIT), is scarce. Using contemporary vestibular function tests, this study examines the vestibular function of patients with profound hearing loss (HL) after meningitis. Methods: Review of the literature and retrospective controlled study. Patients: Twenty-one consecutive patients with profound HL after meningitis (cochlear implant candidates) matched with 20 patients with profound HL of unknown etiology and examined during the period 2013-2018. Outcome Measure: Vestibular function loss, as evaluated with VHIT vestibulo-ocular reflex (VOR) gain, eye movement saccades, and cervical vestibular-evoked myogenic potentials (cVEMPs). The results of ...

Morphological changes in the vestibular system associated with aging are well documented, but the ability to measure these changes clinically has been limited. Two such tests that have been useful for this purpose are Dynamic Visual Acuity (DVA) and Vestibular Evoked Myogenic Potentials (VEMP). DVA is reportedly sub served by the angular vestibulo-ocular reflex (aVOR) for far distances (,2 m) and the linear VOR (lVOR) at near distances (2 m) and the linear VOR (lVOR) at near distances (,1 m). The VEMP also has been shown to be sub served by the linear otolith system. The current study characterized age-related changes in DVA (distance, speed & neck condition) and VEMP in three groups of adults (20-30 yrs, 65-74 yrs, & 75-85 yrs) and analyzed the relationship between the VEMP and DVA. Strength of muscle contraction was monitored by having patients press their heads against a stabilized blood pressure cuff. A significant age-related decline was seen in VEMP amplitude and threshold in the ...

TY - JOUR. T1 - The effects of target wavelength on dynamic visual acuity under photopic and scotopic viewing. AU - Long, G. M.. AU - Garvey, Philip M.. PY - 1988/1/1. Y1 - 1988/1/1. N2 - The effects of target wavelength on the resolution of moving targets were investigated over a range of target velocities under both photopic and scotopic viewing conditions. The wavelength of the photopically matched targets had no effect on dynamic acuity under the bright background condition. However, with low background luminance the wavelength of the targets had pronounced effects, with blue targets producing far superior resolution and red targets, the poorest resolution. These results were maintained over both 250- and 400-ms target durations and regardless of whether initial target position was foveal or peripheral. The likely contribution of the rod system to dynamic visual acuity under some conditions is proposed, and possible implications for applied settings are discussed.. AB - The effects of target ...

Our study results showed moderate SVV effects with a 30° head tilt. However, our experiment notably revealed that two methodological factors (the participants gender and the angle size of the stimulus) had a statistically significant effect on the SVV in general and on the head-tilt effect in particular. Our second data analysis revealed that gender and angle size had additive effects on the deviation of the estimated SVV. The women tended to deviate their SVV in the direction of the head-tilt, whereas the opposite effect was found in men. Moreover, the head-tilt effect was modulated by the stimulus angle size. A large stimulus angle size led to deviations in the direction of the head-tilt, whereas a small angle size gave the opposite effect.. We suggest that these methodological factors could be partly involved in some of the differences found in the literature concerning the effect of head-tilt on the SVV. For instance, an experiment in which the SVV is tested with a large stimulus angle ...

A new test for the assessment of psychomotor recovery - the perceptive accuracy test - was designed and tested in a group of volunteers. It was found to be reproducible and not associated with any significant learning. Two hundred patients (ASA I-ll) undergoing day care arlhroscopic surgery were then studied in order to determine which anaesthetic technique is associated with the best recovery profile. No pharmacological premedication was given to any of the patients. The methodology was standardized in all studies so that the anaesthetic technique was similar between the groups, except for the study dmgs. Postural stability was measured following the injection of midazolam intravenously, using computerized dynamic posturography, Recovery was assessed using a combination of tests including a recovery scale, psychomotor tests and assessment of mood. Discharge times and post-operative complications were also recorded. Results showed that induction of anaesthesia with propofol followed by ...

PURPOSE: To characterize the effect of passive vertical head motion on dynamic visual acuity of young, normally sighted subjects wearing telescopic spectacles, and to relate this to the velocity of images on the retina. METHODS: Static visual acuity was measured without motion. Dynamic visual acuity was measured during vertical, sinusoidal motion of either optotypes or of a servo-driven rotating chair in which subjects were seated. Dynamic visual acuity for head motion was measured unaided, as well as with 1.9X, 4X, and 6X telescopic spectacles. Vertical eye movements were recorded using magnetic search coils. RESULTS: During optotype motion, acuity declined with increasing velocity to a minimum of approximately 20/200 at 100 degrees/sec. Pursuit gain (eye velocity/optotype velocity) for moving optotypes was low except for optotype velocities of 20 degrees/sec of less. Dynamic visual acuity without telescopic spectacles was not sensitive to head motion. Static visual acuity improved with ...

We measured static, kinetic, and dynamic visual acuity (SVA, KVA, and DVA, respectively) of Japanese professional baseball players to ascertain whether there would be any difference in SVA, KVA, and DVA among player groups stratified according to their performance level. Methods: The subjects were 102 male professional baseball players

As coexisting vestibular and cochlear lesions are of etiological importance, evaluation of children with congenital or early acquired hearing impairment (HI) should include vestibular assessment. A rotation test requires specific equipment and allows only detection of bilateral vestibular impairment. An impulse or head thrust test allows assessment of one ear at a time, detects more pronounced caloric side differences and can be performed without any equipment. We report a consecutive series of children with profound sensorineural HI investigated at a tertiary hospital unit. Age at taking first steps without help, the results of temporal bone images (CT/MRT) and vestibular tests were collected retrospectively from patient files. The children were 12 to 90 months old at the time they attended both a rotation and an impulse test. All 14 children cooperated in the impulse test, and 12 completed the vestibular rotation test successfully. Three out of 14 children tested so far have been confirmed to ...

Vestibular rehabilitation is an evidence based treatment for peripheral unilateral vestibular hypofunction (UVH). It is effective in improving physical function (balance, gait and dynamic visual acuity) and in reducing symptoms of dizziness, but precise effects on gait are less well known. The increasing prevalence of technology worldwide has produced opportunities for professionals in the area of vestibular rehabilitation. One technology, virtual reality, has potential but evidence relating to its effectiveness is lacking. The thesis contains four studies related to two main objectives. The first objective was to investigate the effectiveness of an off-the-shelf virtual reality system, the Nintendo Wii Fit Plus™ (NWFP™) compared to conventional vestibular rehabilitation. In preparing to investigate effectiveness, study one quantified the usability and safety of the NWFP™ and found that patients with vestibular disease enjoyed balance exercises on the NWFP™ and perceived that it was beneficial.

BACKGROUND A Cochrane review from 2003 found that about 30% of people 65 years or older each year fall and that number is even higher for elder people living in institutions. Falls are the cause of 95% of all hip fractures, resulting in prolonged hospitalization and prolonged disability. In patients who are referred to the emergency room after unexplained fall, a study of 564 patients showed that 80% of the patients had vestibular symptoms characterized by balance problems, nausea, impairment, vomiting, and dizziness. 41% of the patients had dizziness suggesting a dysfunctional vestibular system called vestibular dysfunction. In patients with vestibular dysfunction, vestibular rehabilitation (VR) can reduce fall risk. Several studies show however that the elderly has a decreased compliance in relation to the performance of home exercise.. A solution to support the older vestibular rehabilitation process and to maintain the achieved level of functionality after the rehabilitation process is the ...

The improvements noted in people with MS occurred despite the fatigue observed in many participants while completing the 3- to 5-hour study protocol. Fatigue was surmised by asking participants if they were fatigued and recording the number of rest breaks that participants with MS required. Many participants with MS required multiple rest breaks during the testing session. None of the age- and sex-matched controls required additional rest breaks during the testing session. Despite people with MS typically noting fatigue as a limiting factor in daily function,4 the potential effect of fatigue on single-session performance is uncertain. Morris et al.29 reported no difference in gait parameters when repeating four 10-m gait trials later in the same day for people with MS. McLoughlin et al.30 reported that at the end of the 6-Minute Walk Test, people with MS had poorer spatiotemporal gait parameters and reported higher levels of fatigue. Age- and sex-matched control participants did not show these ...

Vision, somatosensory, and vestibular inputs each contribute unique information regarding body position and motion contributing to postural control. This chapter focuses on vestibular contributions to postural stability, and discusses the effect of peripheral vestibular loss on balance and postural control. A method utilized to study the role of vestibular inputs is to directly stimulate the vestibular system. The effect of vestibular loss on the amplitude of muscle response at the ankle is related to several factors, the most important being the degree of deficit. Individuals with chronic unilateral vestibular hypofunction (UVH) have the largest amplitude of muscle response, followed by those with acute UVH and individuals with bilateral vestibular hypofunction (BVH) had the smallest amplitude of responses. The chapter discusses the effect of eye movements on balance, and describes the role of vestibular rehabilitation (VR) in the remediation of imbalance and gaze instability ...

Postural control disorders are among the most frequent motor disorder symptoms associated with multiple sclerosis. This study aims to demonstrate the potential improvements in postural control among patients with multiple sclerosis who complete a telerehabilitation program that represents a feasible alternative to physical therapy for situations in which conventional treatment is not available. Fifty patients were recruited. Control group (n = 25) received physiotherapy treatment twice a week (40 min per session). Experimental group (n = 25) received monitored telerehabilitation treatment via videoconference using the Xbox 360® and Kinect console. Experimental group attended 40 sessions, four sessions per week (20 min per session).The treatment schedule lasted 10 weeks for both groups. A computerized dynamic posturography (Sensory Organization Test) was used to evaluate all patients at baseline and at the end of the treatment protocol. Results showed an improvement over general balance in both groups

Balance disorders are frequent with aging. They are particularly important because they decrease social autonomy of the aged subjects and they often provoke falls. The cause is always multifactorial. There is evidence that aging affects multiple sensory inputs, as well as the muscoloskeletal system and central nervous system ability to perform sensorimotor integration. For the evaluation of decreased balance skills in elderly, a specific questionnaire has been prepared, in order to identify high risk of falling called falling risk inventory (FRI) questionnaire, and a complex psycho-sensory-motor test has been studied by means of posturography, in order to detect specific vestibular impairment. Regarding ethiopathogenesis of balance disorders in aged subjects, because the decline of behavioral and cognitive performances are due also to decline of biological rhythm control, the role of melatonin (the hormone regulating circadian rhythms, being strictly connected with cerebellar function, and it is ...

Stroke is caused when an artery carrying blood from heart to an area in the brain bursts or a clot obstructs the blood flow thereby preventing delivery of oxygen and nutrients. About half of the stroke survivors are left with some degree of disability. Innovative methodologies for restorative neurorehabilitation are urgently required to reduce long-term disability. The ability of the nervous system to respond to intrinsic or extrinsic stimuli by reorganizing its structure, function, and connections is called neuroplasticity. Neuroplasticity is involved in post-stroke functional disturbances, but also in rehabilitation. It has been shown that active cortical participation in a closed-loop brain machine interface (BMI) can induce neuroplasticity in cortical networks where the brain acts as a controller, e.g., during a visuomotor task. Here, the motor task can be assisted with neuromuscular electrical stimulation (NMES) where the BMI will act as a real-time decoder. However, the cortical control and

FUNCTION: This gene encodes a member of the Eph receptor family of receptor tyrosine kinase transmembrane glycoproteins. These receptors consist of an N-terminal glycosylated ligand-binding domain, a transmembrane region and an intracellular kinase domain. The encoded receptor preferentially binds membrane-bound ephrin-B ligands and is involved in nervous system and vascular development. This gene is used as a marker of intestinal stem cells. Homozygous knockout mice for this gene exhibit impaired axon guidance and vestibular function. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015 ...

As the highly infectious coronavirus jumped from China to country after country in January and February, the U.S. Centers for Disease Control and Prevention lost valuable weeks that could have been used to track its possible spread in the United States because it insisted upon devising its own test.. The federal agency shunned the World Health Organization test guidelines used by other countries and set out to create a more complicated test of its own that could identify a range of similar viruses. But when it was sent to labs across the country in the first week of February, it didnt work as expected. The CDC test correctly identified COVID-19, the disease caused by the virus. But in all but a handful of state labs, it falsely flagged the presence of the other viruses in harmless samples.. As a result, until Wednesday the CDC and the Food and Drug Administration only allowed those state labs to use the test - a decision with potentially significant consequences. The lack of a reliable test ...

Ethanol affects many parts of the nervous system, from the periphery to higher cognitive functions. Due to the established effects of ethanol on vestibular and oculomotor function, we wished to examine its effect on two new tests of the vestibulo-ocular reflex (VOR): the video head impulse test (vHIT) and dynamic visual acuity (DVA). We tested eight healthy subjects with no history of vestibular disease after consumption of standardized drinks of 40% ethanol. We used a repeated measures design to track vestibular function over multiple rounds of ethanol consumption up to a maximum breath alcohol concentration (BrAC) of 1.38 per mil. All tests were normal at baseline. VOR gain measured by vHIT decreased by 25% at the highest BrAC level tested in each subject. Catch-up saccades were negligible at baseline and increased in number and size with increasing ethanol consumption (from 0.13° to 1.43° cumulative amplitude per trial). DVA scores increased by 86% indicating a deterioration of acuity, ...

Bilateral vestibulopathy (BVP) can affect visual acuity in dynamic conditions, like walking. This can be assessed by testing Dynamic Visual Acuity (DVA) on a treadmill at different walking speeds. Apart from BVP, age itself might influence DVA and the ability to complete the test. The objective of this study was to investigate whether DVA tested while walking, and the drop-out rate (the inability to complete all walking speeds of the test) are significantly influenced by age in BVP-patients and healthy subjects.Forty-four BVP-patients (20 male, mean age 59 years) and 63 healthy subjects (27 male, mean age 46 years) performed the DVA test on a treadmill at 0 (static condition), 2, 4 and 6 km/h (dynamic conditions). The dynamic visual acuity loss was calculated as the difference between visual acuity in the static condition and visual acuity in each walking condition. The dependency of the drop-out rate and dynamic visual acuity loss on BVP and age was investigated at all walking speeds, as well ...

Spasmodic torticollis is an extremely painful chronic neurological movement disorder causing the neck to involuntarily turn to the left, right, upwards, and/or downwards. The condition is also referred to as cervical dystonia. Both agonist and antagonist muscles contract simultaneously during dystonic movement. Causes of the disorder are predominantly idiopathic. A small number of patients develop the disorder as a result of another disorder or disease. Most patients first experience symptoms midlife. The most common treatment for spasmodic torticollis is the use of botulinum toxin type A. Initial symptoms of spasmodic torticollis are usually mild. Some feel an invisible tremor of their head for a few months at onset. Then the head may turn, pull or tilt in jerky movements, or sustain a prolonged position involuntarily. Over time, the involuntary spasm of the neck muscles will increase in frequency and strength until it reaches a plateau. Symptoms can also worsen while the patient is walking ...

How is vestibular disease treated? To diagnose vestibular disease, the veterinarian carefully performs diagnostic tests, examining the ear canals and performing a neurological exam. After it is certain that vestibular disease is the cause of the pets symptoms, very little can be done. There is not a cure for vestibular disease, so treatment usually involves curing the side-effects; the veterinarian can prescribe a medication to relieve nausea or a sedative that helps your pet manage its balance complications. The disease will gradually resolve on its own over the next 7 to 30 days. There remains no way to accelerate this process. Also, for some pets, the head-tilt side-effect will remain permanent. Once a pet gets vestibular disease, it is very rare that it reoccurs, though it is entirely possible for this to happen. For pets suffering from vestibular disease caused by another serious medical issue, further testing and attention may be necessary. If your pet requires further care, the ...

Balance retraining and vestibular rehabilitation are used to treat balance disorders and movement related dizziness. Balance is a complex function that involves the coordination of many body systems. Balance requires the ability to produce movements and interpret information about your bodys position in space. Your visual system provides information about your environment. Proprioceptive nerve endings throughout your body provide information about the location of your body in space. Your vestibular system, located in your inner ear, is needed for balance and position sense. Coordinated muscle movements continually move your body and keep it in an upright position. If any of the systems are disrupted, balance problems and dizziness can occur.. Balance and dizziness can result from neurological disorders, such as a stroke or traumatic brain injury. These conditions change the way nerve signals travel or are processed in the brain. Trauma or disease can affect the vestibular system in the inner ...

In this study we aimed to evaluate the effects of a physiotherapy protocol on balance, anterior displacement and rotation in elderly with vertigo. As a main finding, it improved balance and anterior displacement.. Neuroplasticity occurs when exercise sensory disturbances generated by the adjustment requests the need to be taken by the central nervous system [6]. Therefore, the development of an exercise protocol that addresses primarily the repetition, favors the phenomenon of habituation that through sensory stimulation promotes vestibular compensation due to neuronal plasticity neuronal. This phenomenon is obtained by performing repetitive movements, which attenuates the vestibular response and the amplitude of nystagmus. The repetition, in addition to promoting adaptation to movement, stimulates the peripheral sensory organ, responsible for creating new automatic body balance [1].. We reported benefic effects of this physiotherapy protocol on elderly with vertigo. The vestibular ...

Recent work has demonstrated that the symptoms of common vestibular disorders may be linked with certain environmental factors. By Matthew G. Crowson MDHave you ever wondered if vestibular disorders and their symptoms are influenced by the environment?ATMOSPHERIC PRESSUREChanges in atmospheric pressure may affect patients with Mènières Disease.1 In a recent study,

The variables which best discriminated between the dizzy subjects and the controls were computerised dynamic posturography, computerised psychiatric assessment, and the diagnosis. Very few patients had purely psychogenic symptoms32; most had deficient postural control or signs of some balance system dysfunction or medical disorder which could account for their dizziness. However, gross vestibular abnormalities were rare in this sample, whereas neurotic disturbance was extremely common. Moreover, patients could not be readily classified as having dizziness due either to physical or psychiatric dysfunction, as signs of balance system dysfunction were as common among those with psychiatric disturbance as among those without.. The clinical profile these results suggest is of prevalent, mild combined physical and psychiatric disorder. This mixed aetiology is remarkably similar to that found in samples of dizzy patients drawn from hospital outpatient clinics9 12 and primary care.16 26 Indeed, there is ...

Two sensory stimuli are required for significant adaptation of the VOR: vision and head motion. Traditionally, adaptation paradigms designed to enhance the gain of the VOR have been done with short-term (less than 1 hour) or long-term (greater than 1 day) time exposure. A number of VOR adaptation studies have demonstrated a robust capability for changing the normal VOR by coupling head motion with target motion. When the viewed targets move in such a manner that the image slips on the retina, the VOR is recalibrated. The direction of the recalibrated VOR (increased or decreased) depends on the direction of the target motion in relation with the head motion. During head rotation, visual following of targets that move at a velocity different from the head rotation will create an adaptation (change) in the gain of the VOR. This is commonly achieved by one of two means: (1) targets are viewed wearing lenses that maximize the visual world (increases target velocity) or minimize the visual world ...

The most common cause of in-hospital BVF is aminoglycoside toxicity.10 A common misconception among clinicians is that gentamicin ototoxicty is synonymous with deafness. In fact, vestibular function is much more sensitive to aminoglycosides. However, 90% of patients with aminoglycoside-associated vestibular loss will not develop deafness11 - a finding that may explain why most cases of aminoglycoside otoxicity go undetected.10 The typical patient with aminoglycoside vestibular failure12 will have been in intensive care, often with multi-organ dysfunction. If conscious, 20% experience spontaneous episodic vertigo lasting minutes to hours. This is an unexplained phenomenon: vertigo implies a right-left vestibular imbalance, and simultaneous, bilateral vestibular loss would be expected from a systemic ototoxin. The vertiginous episodes wane after a few days as the vestibular function is ablated.. However, attempts to rehabilitate and mobilise patients with aminoglycoside vestibulotoxicity are ...

BACKGROUND/AIMS: Unsteadiness in the elderly is a frequent complaint and a strong predictor of falls and psychological distress. Although there is a general consensus that it is a multifactorial condition, recent studies have focused on the role of aging of the vestibular system as a possible cofactor. The aim of our work was to assess horizontal canal function in the elderly. METHODS: We evaluated the gain of horizontal vestibulo-ocular reflex (VOR) with a video head impulse test on a sample of 58 subjects aged ,70 years without lifetime episodes of vertigo and correlated the value with different clinical conditions (hypertension, diabetes, prior cardiovascular and vascular disorders of the central nervous system, and falls ...

A useful feature in each section is a table summarizing quick tips for rapid interpretation. These really nicely summarize the content of the chapter. In addition, an especially useful feature is the DVD, which has some nice recordings of classic nystagmus patterns, which are particularly useful for new trainees to understand the interpretation of eye movements.. This book is particularly useful for residents rotating on otology or nurse practitioners or allied health personnel who are beginning involvements of patient care with vestibular disorders.... Although the textbook goes a bit beyond the stated purpose in describing some of the treatment strategies for common vestibular disorders, I found this aspect of the book quite engaging in that it provides a useful rationale for obtaining the various vestibular studies.. Overall, the authors have accomplished their goal of providing a succinct summary useful for trainees in understanding vestibular function testing. ...

Randomisation of 195 participants allocated 65 to each of the Tai Chi, resistance, and stretching groups. Interventions: The Tai Chi group. underwent a Tai Chi program, the resistance group 8 to 10 leg muscle strengthening exercises, while the stretching group performed stretching exercises involving the upper body and lower extremities. All three groups trained for 24 weeks (60 minutes per session, two sessions per week). Outcome measures: The primary outcomes were two indicators of postural stability - maximum excursion and directional control derived from dynamic posturography. The secondary outcomes were stride length, gait velocity, knee flexion and extension peak torque, functional reach, timed-up-and-go test, and motor section of the Unified Parkinsons U0126 manufacturer Disease Rating Scale (UPDRS III). The outcomes were measured at baseline, at 12 and 24 weeks, and 3 months after termination of the intervention. this website Results: 185 participants completed the study. At the end of ...
