Identifying Locations Where Self-Reported Dizziness Occurs In Patients With Vestibular Disorders In A Day Hospital Setting

Abstract Background World falls guidelines recommended that where vestibular issues are identified such as Benign Paroxysmal Positional Vertigo (BPPV), therapeutic interventions should always be sought, as potential benefits to health-related quality of life are high (Montaro-Odasso et al., 2022). Identifying potential BPPV in older adults, however, can be challenging, as many older adults experience BPPV as vague unsteadiness rather than dizziness, leading to under diagnosis of the condition (Li et al., 2023). This audit aimed to identify the locations where patients with self- reported dizziness and falls experienced dizziness, and if they subsequently were diagnosed with vestibular disorders. If potential high-risk locations for experiencing dizziness with vestibular issues are identified, this may aid in the timely identification of vestibular disorders. Methods A retrospective chart audit was undertaken in a multidisciplinary day hospital setting, where patients aged 75 years and older attend for assessments. Paper charts of patients discharged from the day hospital between January and March 2024 were reviewed. A Microsoft excel sheet was used to track data. Data on self-reported dizziness and falls as well as the location of dizziness occurring was gathered. Results A total of 103 patient charts were reviewed. Of those, 39 reported experiencing dizziness, with 90% of those patients also reporting a history of falls. 18 of these patients were subsequently diagnosed with vestibular disorders. 78% of patients diagnosed with BPPV reported experiencing dizziness getting out of bed or in their bedroom with 28% also reporting dizziness on getting up from a chair. However, 100% of patients with dizziness and falls without vestibular disorders reported dizziness on getting out of their bed. Conclusion People with all cause dizziness reported dizziness on getting out of bed. Based on the results of this audit, vestibular screening is not aided by questions surrounding location of dizziness occurring.

Vestibular Assessment In Patients With Self-Reported Dizziness And A History Of Falls

Abstract Background World Falls Guidelines recommend that any patient with a history of falls and reporting dizziness should be screened for Benign Paroxysmal Positional Vertigo (BPPV) (Montero-Odasso et al.,2022). Diagnosing and treating BPPV in particular has been shown to reduce the incidence of falls in older adults, however, it is widely underdiagnosed (Li et al., 2023). This audit explored compliance with falls guidelines in a day hospital setting where falls work up assessments take place on older patients (75 years and older). It aimed to identify reasons why vestibular assessments may not have been undertaken and establish methods to improve compliance with the undertaking of vestibular assessments where indicated. Methods A retrospective chart was undertaken for patients who attended a day hospital service for older adults between January and April 2023. A Microsoft excel sheet was used to track data. All data was anonymised and stored on a password encrypted HSE networked drive accessed in the day hospital. Results A total of 97 charts were reviewed, with 31 patients reporting to have experienced dizziness with falls. For 33% of those patients (n=10), a vestibular screen was not carried out. For 7 out of 10 of these patients a screen was not carried out due to insufficient staff training in the area, with one patient not having been referred to physiotherapy, also secondary to insufficient staff training. Conclusion Facilitating adequate access to training in vestibular rehab for healthcare professionals is an essential part of ensuring BPPV and other vestibular disorders are diagnosed and treated in patients with self-reported dizziness and falls. Training as part of undergraduate degrees could be considered to ensure BPPV is diagnosed and treated in a timely manner. Additional staff training was provided in the day hospital setting in question and a re-audit of vestibular screening will take place in summer 2024.

Infant Cervical Vestibular Evoked Myogenic Potentials: A Scoping Review.

Children diagnosed with hearing loss typically demonstrate increased rates of vestibular loss as compared with their peers, with hearing within normal limits. Decreased vestibular function is linked with delays in gross motor development, acquisition of gross motor skills, and academic challenges. Timely development of sitting and walking gross motor skills aids in the progress of environmental exploratory activities, which have been tied to cognitive, language, and vocabulary development. Considering the time-sensitive development of gross motor skills and cognitive, language, and vocabulary development, identifying vestibular loss in infancy can support early intervention. This scoping review analyzes stimulus, recording, and participant factors relevant to assessing cervical vestibular evoked myogenic potentials (cVEMPs) in the infant population. The scoping literature review was conducted on literature published between 2000 and 2023, focusing on articles assessing cVEMPs in infants. Two authors independently followed Preferred Reporting Items for Systematic and Meta-Analysis guidelines for title and abstract screening, full-text review, data extraction, and quality assessments. Sixteen articles meeting the inclusion criteria were included in the analysis. The existing literature lacks consensus regarding stimulus and recording parameters for measuring infant cVEMPs. In addition, the review reveals a decrease in cVEMP response occurrence rates with the severity of hearing loss, especially in cases of severe to profound hearing loss, compared with mild to moderate sensorineural hearing loss in infants. This scoping review demonstrates the increasing use of cVEMP as a reliable tool for objectively assessing infant vestibular function. The lack of consensus in stimulus and recording parameters emphasizes the need for systematic research to establish an evidence-based protocol for cVEMP measurements in infants. Such a protocol will ensure the reliable measurement of cVEMPs in infants and enhance the effectiveness of cVEMP as part of the infant vestibular test battery. In addition, there is a necessity for a comprehensive large-scale study to evaluate the practicality and feasibility of implementing vestibular screening protocols for infants diagnosed with sensorineural hearing loss in the United States.

A - 43 Impact of Pre-Existing Attention-Deficit/Hyperactivity Disorder on Vestibular/Ocular Motor Outcomes Following Concussion

Abstract Purpose The purpose of this study was to examine differences in post-injury VOMS outcomes in athletes with and without pre-existing ADHD. The authors hypothesized individuals with pre-injury ADHD would demonstrate greater NPC distance as well as increased headache and dizziness on the VOMS. Method This prospective cohort study included patients aged 11–29 years who presented to a specialty concussion clinic within 30 days of a diagnosed concussion, categorized into groups with and without pre-existing ADHD. Independent samples t-tests and chi-square tests examined differences between groups in demographics, medical history, injury mechanism, and VOMS outcomes. A follow-up analysis of covariance was performed to determine the influence of significant covariates on VOMS outcomes. Results One hundred eighty-nine participants (107 male; age = 15.9 ¬ ± 2.5 years) were included; 160 (83.3%) without ADHD and 29 (15.1%) with pre-existing ADHD. Participants with pre-existing ADHD demonstrated significantly greater NPC average (5.29 vs. 2.87, p = 0.04) and total dizziness (14.32 vs. 9.54, p = 0.03). When controlling for sex, race, and history of anxiety, only VOMS dizziness total remained significantly different between groups (F(1, 177) = 4.56, p = 0.03). Conclusions Results indicate patients with pre-existing ADHD report higher levels of dizziness during post-injury VOMS when compared to patients without ADHD history. Notably, group differences in NPC were attenuated when controlling for demographic information. Findings reinforce the importance of comprehensive evaluation and assist in interpretation of post-injury vestibular screening for patients with ADHD. Future research should examine recovery trajectories, efficacy of targeted treatments, and influence of post-injury anxiety among individuals with ADHD in order to provide effective treatment recommendations.

Vestibular Hypofunction Screening in Older Cochlear Implant Candidates.

Vestibular loss is associated with increasing age and hearing loss. Cochlear implantation (CI) may be performed in these patients; however, CI can induce vestibular hypofunction (VH) postoperatively. If CI is performed in the "better balancing ear," patients may experience vestibulopathy from new bilateral VH. The objective of this study was to evaluate the rates of VH in older CI candidates, thereby helping to identify patients at increased risk for bilateral VH after CI. Retrospective cohort study from 2019 to 2022 of patients age 60 to 80 years old who underwent videonystagmography (VNG). Tertiary care neurotology practice. VNG, including spontaneous nystagmus, cervical vestibular evoked myogenic potential (cVEMP), caloric stimulation, and rotary chair, was reviewed and stratified by CI candidacy. Patients with prior CI or known vestibular diagnosis were excluded. Thirty-three patients were CI candidates and 184 patients were controls. cVEMP demonstrated a significantly greater rate of unilateral VH in CI candidates (P = .018). Caloric stimulation demonstrated an elevated rate of bilateral VH and presbyvestibulopathy in CI candidates (P = .057 and P = .036, respectively). Rotary chair demonstrated a significantly higher rate of bilateral VH and incomplete vestibular compensation based on reduced gain and gain asymmetry, respectively, in CI candidates (P < .001 and P = .043, respectively). Mean bithermal slow phase velocity sum and rotary chair gain were significantly lower in the CI candidate group (P = .002 and P < .001, respectively). Preoperative identification of VH determined the side of implantation in 4 patients (15%). VH and incomplete vestibular compensation are common and more frequently seen in CI candidates compared to age-matched controls. Vestibular screening can play a role in surgical counseling and planning, and should be considered in older patients undergoing CI.

Vestibular Function Monitoring in a Pediatric Cochlear Implant Program

Purpose: The purpose of this project was to retrospectively evaluate a vestibular screening protocol and results in children with cochlear implants (CIs) to provide information for other clinics considering implementing similar programs. Method: A retrospective analysis of chart data was completed using descriptive statistics and a repeated measures multivariate analysis of variance design in context with the current state of literature on vestibular monitoring in the pediatric CI population. Results: Pre-CI testing was focused on cervical vestibular evoked myogenic potentials (cVEMPs), which is an efficient and obtainable measure in this population. Postimplantation vestibular testing proved challenging with a high no-show/cancellation rate. For patients evaluated both pre- and postimplantation, there was no significant difference across patients noted; however, individual differences were noted. Conclusions: Vestibular monitoring of pediatric CI patients is important for the overall health and development of this population. An overall assessment of the program and options for continuation of the program considering this analysis are also provided. cVEMP testing is a good option for vestibular monitoring in pediatric CI patients; however, a multifaceted approach is most likely needed to address the many challenges that exist.

Evidence for a multidomain clinical assessment of mild traumatic brain injury in older adults

Background There are few guidelines on the appropriate clinical tools to evaluate mTBI in older adults. Objective We aimed to investigate the utility of a multidomain assessment to differentiate older adults with mTBI from controls. Methods Participants included 68 older adults (37% male) aged 60–76 (M = 66.24, SD = 4.50) years. Thirty-four patients were diagnosed with a mTBI at a specialty mTBI clinic within 90 days of injury, and age- and sex-matched to 34 community controls. Participants completed the following assessments: Post-Concussion Symptom Scale (PCSS), Short Fall Efficacy Scale-International (Short FES-I), Generalized Anxiety Disorder-7 Item Scale (GAD-7), Geriatric Depression Scale-5 Item (GDS-5), Wide Range Achievement Test-Fourth Edition (WRAT-4) reading subtest, subtests of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), clock drawing, and Vestibular/Ocular Motor Screening for Concussion (VOMS). Independent-samples t-tests or chi-squared analyses were used to compare assessment results between groups. A logistic regression (LR) was conducted to determine which combination of assessments best identified the mTBI group from controls. Results The mTBI group endorsed significantly more symptoms of concussion (p < .001), balance concerns (p < .001), anxiety (p < .001), and depression (p = 0.04), and performed worse on cognitive (p < .001), vestibular (p < .001), and oculomotor (p = .004) screening relative to controls. The LR (p < .001; r 2 = 0.90) correctly identified 98.5% of older adults and retained concussion (p = .01) and depression (p = .02) symptoms, and cognitive (p = .03) and vestibular (p = .04) screening in the final model. Discussion The current findings support a multidomain assessment model of care for evaluating mTBI in older adults.

Postural control among individuals with and without chronic obstructive pulmonary disease: A cross-sectional study of motor and sensory systems.

Chronic obstructive pulmonary disease (COPD) is considered a heterogenic syndrome with systemic effects, including muscle dysfunction. There is evidence of postural control impairments among individuals with COPD, partly related to muscle weakness. However, research is scarce regarding the other underlying systems of postural control, such as the visual, somatosensory and vestibular system. The aim was to compare postural control, as well as the motor and sensory systems, between individuals with and without COPD. Twenty-two participants with COPD (mean age 74.0 ±6.2 years) and 34 non-obstructive references (mean age 74.9 ±4.9 years) participated in this cross-sectional study. Postural control was assessed with center of pressure trajectory of postural sway in quiet as well as a limits of stability test, calculating mediolateral and anteroposterior amplitudes for each test. Assessment of function in the motor system included maximum hand grip strength, as well as maximum strength in muscles around the hip, knee and ankle joints. Visual acuity, pressure sensibility, proprioception, vestibular screening, and reaction time were also included. Data was compared between groups, and significant differences in postural control were further analyzed with an orthogonal projection of latent structures regression model. There was a significantly increased sway amplitude in the mediolateral direction in quiet stance on soft surface with eyes open (p = 0.014) as well as a smaller anteroposterior amplitude in the limits of stability test (p = 0.019) in the COPD group. Regression models revealed that the mediolateral amplitude was related to visual acuity and the burden of tobacco smoking assessed as pack-years. Further, muscle strength associated with anteroposterior amplitude in limits of stability test in the COPD group, and with age and ankle dorsal flexion strength among the referents. Besides for lower ankle plantar flexion strength in the COPD group, there were however no significant differences in muscle strength. Individuals with COPD had a decreased postural control and several factors were associated with the impairments. The findings imply that the burden of tobacco smoking and reduced visual acuity relate to increased postural sway in quiet stance, and that muscle weakness is related to decreased limits of stability, among individuals with COPD.

Vestibular dysfunction in people who fall: A systematic review and meta-analysis of prevalence and associated factors.

To evaluate the prevalence and factors associated with vestibular dysfunction in people who fall. All electronic records from MEDLINE, CINAHL, Embase and psycINFO databases were searched to 9 December 2022. Participants were adults with at least one fall within the previous year who were exposed to at least one vestibular function test. Any published peer reviewed trial designs were accepted. Included studies were assessed for risk of bias using a modified Epidemiological Appraisal Instrument. The quality of each meta-analysis was assessed using modified Grading of Recommendations Assessment, Development and Evaluation (GRADE). Ten trials (468 participants) were identified, six of which had high methodological quality. Vestibular dysfunction was found in 61% (48.01-72.32) I2 = 78% of participants. The most prevalent type of dysfunction was from tests of vestibulo-ocular reflex at 61% (49.79 to 70.49) I2 = 68%, followed by benign paroxysmal positional vertigo at 22% (10.30-40.32) I2 = 87% and central dysfunction at 11% (2.24-37.76) I2 = 50%. People who fall with vestibular dysfunction had reduced walking function compared to those without dysfunction -0.51 (-0.85 to -0.16) I2 = 11%. Dizziness was not related to vestibular dysfunction in people who fall 0.25 (-0.10 to 0.60), I2 = 0%. The quality of the body of evidence ranged from very low to high. More than one in two people who fall have vestibular dysfunction. Clinicians cannot rely on dizziness report to indicate need for vestibular screening in those who fall. A vestibular screen should be incorporated into a comprehensive falls assessment.

Comparison of Asymmetry between Perceptual, Ocular, and Postural Vestibular Screening Tests

A better understanding of how vestibular asymmetry manifests across tests is important due to its potential implications for balance dysfunction, motion sickness susceptibility, and adaptation to new environments. We report the results of multiple tests for vestibular asymmetry in 32 healthy participants. Asymmetry was measured using perceptual reports during unilateral centrifugation, oculomotor responses during visual alignment tasks, vestibulo-ocular reflex gain during head impulse tests, and body rotation during stepping tests. A significant correlation was observed between asymmetries of subjective visual vertical and verbal report during unilateral centrifugation. Another significant correlation was observed between the asymmetries of ocular alignment, vestibulo-ocular reflex gain, and body rotation. These data suggest that there are underlying vestibular asymmetries in healthy individuals that are consistent across various vestibular challenges. In addition, these findings have value in guiding test selection during experimental design for assessing vestibular asymmetry in healthy adults.

Vestibular Infant Screening-Flanders: What is the Most Appropriate Vestibular Screening Tool in Hearing-Impaired Children?

As children with sensorineural hearing loss have an increased risk for vestibular impairment, the Vestibular Infant Screening-Flanders project implemented a vestibular screening by means of cervical vestibular evoked myogenic potentials (cVEMP) at the age of 6 months for each child with hearing loss in Flanders (Belgium). Given that vestibular deficits can affect the child's development, this vestibular screening should allow early detection and intervention. However, less is currently known about which screening tool would be the most ideal and how vestibular impairment can evolve. Therefore, this study aimed to determine the most appropriate tool to screen for vestibular deficits, to assess the necessity of vestibular follow-up, and to set clinical guidelines for vestibular screening in children with hearing loss. In total, 71 children with congenital or early-onset sensorineural hearing loss were enrolled (mean age at first appointment = 6.7 months). Follow-up was provided at 6 months, 1, 2, and 3 years of age. Below three years of age, the video Head Impulse Test (vHIT) of the horizontal semicircular canals (SCC), the cVEMP, and the rotatory test at 0.16, 0.04, and 0.01 Hz were applied. At 3 years of age, the vHIT of the vertical SCC and ocular vestibular evoked myogenic potentials (oVEMP) were added. To evaluate early motor development, the Alberta Infant Motor Scale (AIMS) results at 6 months and 1-year old were included. At 6 months of age, the highest success rate was obtained with the cVEMP (90.0%) compared to the vHIT (70.0%) and the rotatory test (34.3-72.9%). Overall, vestibular deficits were found in 20.0% of the children, consisting of 13.9% with both SCC and otolith deficits (bilateral: 9.3%, unilateral: 4.6%), and 6.1% with unilateral isolated SCC (4.6%) or otolith (1.5%) deficits. Thus, vestibular deficits would not have been detected in 4.6% of the children by only using the cVEMP, whereas 1.5% would have been missed when only using the vHIT. Although vestibular deficits were more frequently found in severe to profound hearing loss (28.6%), characteristics of vestibular function were highly dependent on the underlying etiology. The AIMS results showed significantly weaker early motor development in children with bilateral vestibular deficits ( p = 0.001), but could not differentiate children with bilateral normal vestibular function from those with unilateral vestibular deficits ( p > 0.05). Progressive or delayed-onset vestibular dysfunction was only found in a few cases (age range: 12-36 months), in which the hearing loss was mainly caused by congenital cytomegalovirus (cCMV). The cVEMP is the most feasible screening tool to assess vestibular function in 6-months-old children with hearing loss. Although the majority of children with vestibular deficits are detected with the cVEMP, the vHIT seems even more sensitive as isolated SCC deficits are associated with specific etiologies of hearing loss. As a result, the cVEMP is an appropriate vestibular screening tool, which is advised at least in severe to profound hearing loss, but certain etiologies require the addition of the vHIT (i.e., cCMV, meningitis, cochleovestibular anomalies with or without syndromic hearing loss).

153 AN EVALUATION OF OLDER PERSONS WITH VESTIBULAR DYSFUNCTION AS IDENTIFIED DURING COMPREHENSIVE GERIATRIC ASSESSMENT

Abstract Background Vestibular dysfunction accounts for 25% of dizziness complaints. In 30-50% of these cases, dizziness is attributed to Benign Paroxysmal Positional Vertigo (BPPV). Thirty percent of people will experience vestibular dysfunction in their lifetime, with likelihood increasing with age. Individuals with vestibular dysfunction are eight times more likely to experience a fall. Vestibular assessment and rehabilitation services can be difficult to access. Methods A Plan, Do, Study, Act (PDSA) cycle was undertaken. All referrals to the Older Persons’ Services Clinics from November 2021 to May 2022 were triaged by an Integrated Care Team for the Older Person and scheduled for Comprehensive Geriatric Assessment (CGA). In the course of CGA, patients who reported symptoms suggestive of vestibular dysfunction received assessment by a Physiotherapist with vestibular expertise. Results were entered on an Excel spreadsheet and analysed using descriptive statistics. Results Six patients (4 female, 2 male) received vestibular assessment and treatment. Mean age was 75 years (SD: 11) with median Clinical Frailty Score of 4 (vulnerable). Reported symptoms were dizziness (n=3) and spinning (n=3). Sixteen percent (n=1) reported a fall and 66% (n=4) reported fear of falling. All patients had symptom duration of &amp;gt;2 years. Following vestibular assessment, the following diagnoses were made; right posterior canal BPPV, (n=2), vestibular migraine (n=2), right horizontal canal canalithiasis BPPV, with secondary diagnosis of persistent postural-perceptual dizziness (n=1) and left peripheral vestibular hypofunction due to vestibular neuronitis (n=1). The mean number of Physiotherapy visits per person was 4. Three patients reported full resolution of symptoms. The remaining 3 reported an improvement in symptoms and confidence to self-manage. Conclusion This small cohort of older persons with chronic vestibular dysfunction benefited from vestibular diagnosis and intervention. The next step of the process is to include specific vestibular screening questions into CGA. This will enable Integrated Care Team members to screen more specifically for vestibular dysfunction.

Cervical vestibular evoked myogenic potentials in 3-month-old infants: Comparative characteristics and feasibility for infant vestibular screening.

ObjectiveWe compared the characteristics of air-conducted sound cervical vestibular evoked myogenic potential (ACS-cVEMP) and bone-conducted vibration cVEMP (BCV-cVEMP) among 3-month-old infants with normal hearing and sensorineural hearing loss (SNHL), and healthy adults to explore the feasibility and optimal strategies for infant vestibular screening.Methods29 infants (58 ears) were divided into two groups according to hearing (group I: normal hearing ears; group II: SNHL ears), 20 healthy adults were defined as group III. The results of response rate, P13 and N23 latency, P13-N23 interval, amplitudes, and corrected interaural asymmetry ratio (IAR) were recorded and compared among three groups.ResultsThe response rates of ACS-cVEMP in three groups were 88.89, 62.00, 100%, respectively. The P13 and N23 latencies, and P13-N23 interval did not differ significantly between group I and II (p = 0.866, p = 0.190, p = 0.252). A significant difference was found between group I and III (p = 0.016, p < 0.001, p < 0.001). No significant difference was observed in raw or corrected amplitude between group I and II (p = 0.741, p = 0.525), while raw and corrected amplitudes in group III were significantly larger than group I (p < 0.001, p < 0.001). For BCV-cVEMP, the response rates in three groups were 100, 86.36, 100%, respectively, No significant difference existed in the P13 and N23 latency, or P13-N23 interval between group I and II (p = 0.665, p = 0.925, p = 0.806), however, P13 and N23 latencies were significantly longer in group III than group I (p < 0.001, p = 0.018), but not in P13-N23 interval (p = 0.110). There was no significant difference in raw or corrected amplitude between group I and II (p = 0.771, p = 0.155) or in raw amplitude between group I and III (p = 0.093), however, a significant difference existed in corrected amplitude between group I and III (p < 0.001).ConclusionsCompared with adults, 3-month-old infants with normal hearing presented with equivalent response rates, shorter P13 and N23 latencies, smaller corrected amplitudes, and a wider IAR range for both ACS and BCV-cVEMP. SNHL infants had equivalent response rates of BCV-cVEMP, lower response rates of ACS-cVEMP than normal hearing infants. When responses were present, characteristics of ACS and BCV-cVEMP in SNHL infants were similar with normal hearing infants. ACS combined with BCV-cVEMP are recommended to improve the accuracy of vestibular screening.

Three Years of Vestibular Infant Screening in Infants With Sensorineural Hearing Loss.

Although vestibular deficits are more prevalent in hearing-impaired children and can affect their development on many levels, a pediatric vestibular assessment is still uncommon in clinical practice. Since early detection may allow for timely intervention, this pioneer project has implemented a basic vestibular screening test for each six-month-old hearing-impaired infant in Flanders, Belgium. This study aims to report the vestibular screening results over a period of three years and to define the most important risk factors for abnormal vestibular screening results. Cervical Vestibular Evoked Myogenic Potentials with bone-conduction were used as a vestibular screening tool in all reference centers affiliated to the Universal Newborn Hearing Screening Program in Flanders. From June 2018 until June 2021, 254 infants (mean age: 7.4 months, standard deviation: 2.4 months) with sensorineural hearing loss were included. Overall, abnormal vestibular screening results were found in 13.8% (35 of 254) of the infants. The most important group at risk for abnormal vestibular screening results were infants with unilateral or bilateral severe to profound sensorineural hearing loss (20.8%, 32 of 154) (P < .001, odds ratio = 9.16). Moreover, abnormal vestibular screening results were more prevalent in infants with hearing loss caused by meningitis (66.7%, 2 of 3), syndromes (28.6%, 8 of 28), congenital cytomegalovirus infection (20.0%, 8 of 40), and cochleovestibular anomalies (19.2%, 5 of 26). The vestibular screening results in infants with sensorineural hearing loss indicate the highest risk for vestibular deficits in severe to profound hearing loss, and certain underlying etiologies of hearing loss, such as meningitis, syndromes, congenital cytomegalovirus, and cochleovestibular anomalies.

Influence of screening devices and protocol on audiological outcome of 25 years of universal neonatal hearing and vestibular screening in Flanders

Background: Congenital hearing loss has been linked with life-long deficits in speech and language abilities and children with vestibular deficits show delayed development of gross motor milestones. Aim and scope of the research: To analyze if the universal neonatal hearing screening (UNHS) and vestibular screening program in Flanders meet the current guidelines and benchmarks of the position statements from the Joint Committee on Infant Hearing and how big the impact of screening devices and strategy is. Methods: The UNHS is organized since 1997 by a Flemish public child care organization and performed by trained nurses. It is based on a two-step screening with Automated Auditory Brainstem Responses and in case of absent responses (named ‘refer’), audiological and medical diagnostic are done in one of 21 certified centers. Vestibular screening started in 2018 around the age of 6 months with cervical Vestibular Evoked Myogenic Potentials (cVEMP) for all children with confirmed permanent hearing loss. Results: The coverage of the UNHS from 1998 till 2020 was 96,3 % (range 91,1 – 98%). There was a bilateral refer for 0,27 % of the infants and unilateral refer for 0,37 %. A sensorineural or mixed hearing loss &gt; 40 dB was diagnosed in 32 % of the referred infants, a conductive hearing loss which often resolved over time in 39 %, a normal hearing in 25% and 4,7 % were lost in follow-up for the diagnostic evaluation. There was an effect of the screening device on the detection of conductive hearing losses and false-positive cases. The incidence was higher with the MAICO MB Classic® device compared to the ALGO® devices. The incidences of sensorineural or mixed hearing loss were independent of the screening device and remained relatively stable over the years. A vestibular deficit was found in 9,5 % of all children with sensorineural hearing loss. The incidence was significantly higher in infants with severe or profound hearing loss (p=0,003) Conclusion: The Flemish UNHS has a high coverage, low referral rate and low loss of follow-up rate. Strict monitoring and follow-up by a central organization are essential for optimal results. Long-term follow-up remains a challenge.

Postural balance problems in people with intellectual disabilities: Do not forget the sensory input systems.

This pilot study aimed to explore the impact of visual, auditory and vestibular dysfunctions on the postural balance performance in adults with intellectual disabilities. Additionally, a comparison was made between the subjects with intellectual disabilities and a control group concerning static and dynamic balance tasks. Thirty adults with intellectual disabilities and 25 control subjects received a postural balance assessment. Additionally, the experimental group was subjected to a visual, auditory and vestibular screening. The experimental group performed significantly worse and/or showed more sway compared to the control group for all balance tasks (p < .01) except the timed up and go test. Within the experimental group, a significant positive correlation (rs (24)=0.513, p=.007) was observed between the number of failed sensory screening items and the number of failed balance tasks. These findings suggest significant involvement of peripheral sensorial deficits in the balance problems that people with intellectual disabilities often experience.

Does Vestibular-Ocular-Motor (VOM) Impairment Affect Time to Return to Play, Symptom Severity, Neurocognition and Academic Ability in Student-Athletes following acute Concussion?

ABSTRACT Introduction: Research indicates Sports-Related Concussion (SRC) impairs Vestibular-Ocular-Motor (VOM) function. The aim was to explore if VOM impairment correlates with longer Return To Play (RTP), symptom burden, neurocognitive performance and academic capability. Participants: 40 (61.4% male) Loughborough University, UK, rugby union student-athletes who sustained 42 SRCs. Methods: Student-athletes completed an assessment battery during pre-season (baseline), 2, 4, 8 and 14 days post-SRC and prior to RTP and were managed according to the rugby Football Union’ community pathway. Outcome measures: Vestibular Ocular-Motor Screening (VOMS), Immediate Post-Concussion Assessment and Cognitive Test, Post-Concussion Symptom Scale, Perceived Academic Impairment Tool questionnaire and percentage of academic activities specifically missed due to SRC. Results: VOMS scores were significantly (p < 0.005) greater than baseline at all time points except RTP. Presence of VOM dysfunction at 14 days post-SRC significantly correlated with a longer RTP, greater symptom burden and increased odds ratio at 2, 4 and 8 days and academic time loss at 2, 4 and 8 days post-SRC. Conclusion: VOM impairment is associated with an increased symptom burden and impaired academic capability, and a longer time to RTP when present at 14 days post-SRC.

Video head impulse test saccades and loss of cervical vestibular evoked myogenic potentials are late vestibular footprints of cochlear implantation.

Cochlear implantation may be complicated by concurrent injury to the vestibular apparatus, potentially resulting in disabling vertigo and balance problems. Information on vestibular function before implantation as measured by the video head impulse test (VHIT) and cervical vestibular evoked myogenic potentials (cVEMPs) is scarce and literature on long-term effects is non-existing. We aimed to evaluate how vestibular function was affected by cochlear implantation (CI), as measured by VHIT and cVEMPs in the late phase after implantation. Retrospective repeated measurement study. Among the 436 patients elected for CI surgery during 2013 to 2018, 45 patients met the inclusion criteria (CI recipients with a vestibular assessment prior to the first CI and a repeated vestibular assessment after the CI operation). VHIT and cVEMPs before and after cochlear implantation. Main outcome measures were vestibular function as evaluated by VHIT gain, saccades and cVEMPs. The mean time between first and second vestibular screening was 19 months. The mean VHIT gain on implanted ears was 0.79 before the operation and showed no change at follow-up (p = 0.65). Likewise, the number of abnormal VHIT gain values was equal before and after the operation (p = 0.31). Preoperatively, saccades were present on 12 ears (14%) compared with 25 ears (29%) postoperatively (p = 0.013) and were associated with significantly lower VHIT gain values. Preoperatively, positive cVEMPs were found in 20 CI ears (49%) and 24 contralateral ears (62%). 10 CI ears lost cVEMP postoperatively compared with 2 ears on the contralateral side (p = 0.0047). Even though VHIT gain has been reported to be affected in the immediate post-implantation period, the findings in this study show that VHIT gain is normalized in the long-term. However, cochlear implantation is associated with the occurrence of VHIT saccades in the long-term and these are associated with lower VHIT gain values. In addition, cVEMP responses are significantly reduced long-term on implanted ears, which agrees with other studies with shorter follow-up.

Vestibular Infant Screening (VIS)\u2013Flanders: results after 1.5\xa0years of vestibular screening in hearing-impaired children

Due to the close anatomical relationship between the auditory and vestibular end organs, hearing-impaired children have a higher risk for vestibular dysfunction, which can affect their (motor) development. Unfortunately, vestibular dysfunction often goes unnoticed, as vestibular assessment in these children is not standard of care nowadays. To timely detect vestibular dysfunction, the Vestibular Infant Screening–Flanders (VIS–Flanders) project has implemented a basic vestibular screening test for hearing-impaired infants in Flanders (Belgium) with a participation rate of 86.7% during the first year and a half. The cervical Vestibular Evoked Myogenic Potentials (cVEMP) test was applied as vestibular screening tool to map the occurrence of vestibular (mainly saccular) dysfunction in this population. At the age of 6 months, 184 infants were screened. No refers on vestibular screening were observed in infants with permanent conductive hearing loss. In infants with permanent sensorineural hearing loss, a cVEMP refer rate of 9.5% was observed. Failure was significantly more common in infants with severe-profound compared to those with mild-moderate sensorineural hearing loss (risk ratio = 9.8). Since this is the first regional study with a large sample size and successful participation rate, the VIS–Flanders project aims to set an example for other regions worldwide.

Vestibular Screening Before Cochlear Implantation: Clinical Implications and Challenges in 409 Cochlear Implant Recipients.

Cochlear implantation (CI) carries a risk of loss of vestibular function following surgery. Thus, vestibular assessment presurgery is used to identify vestibulopathy that may contraindicate implantation and guide in selecting the candidate ear. The aim of this study was to evaluate the clinical implications of preoperative vestibular assessment, and to identify challenges in performing vestibular testing in patients with profound hearing loss, i.e., CI candidates. Retrospective study of all CI recipients implanted since the introduction of a vestibular screening program. Tertiary referral center in 2013. CI candidates routinely underwent testing with the video head impulse test (VHIT) and the cervical vestibular evoked myogenic potential (cVEMP) test as a part of the CI work up. Three hundred thirty-five individuals were screened before the first CI and 74 individuals before the second CI. In 301 cases (73.6%), the vestibular function was considered normal and consequently carried no contraindications for surgery or implications for choice of ear to be implanted. Bilateral vestibular loss was found in 43 cases (10.5%) and unilateral vestibular loss was found in 62 cases (15.2%). In the latter cases, evaluation of multiple variables was indicated to select candidate ear. In nine implanted patients (2.2%), a relative contraindication to operate based on an "only balancing" ear was overruled by other factors. Vestibular testing was challenged by various factors (e.g., neck immobility, eye tracking issues, communication, and other patient issues), limiting the vestibular data output. This resulted in omittance, testing failure, or interpretation uncertainty 24 times (5.9%) for VHIT and 65 times (15.9%) for cVEMP. Vestibular screening is an important part of the clinical workup with respect to selection of candidate ear for cochlear implantation, as 15.2% of CI candidates present with unilateral vestibulopathy. Challenges in performing the vestibular tests are not uncommon, as test failure occurred in 15.9% of cases for the cVEMP and 5.9% for the VHIT. The most common reasons for test failure were neck immobility, communication issues, and problems of pupil tracking.
