Abstract
OBJECTIVE Vestibular dysfunction, which may lead to delayed motor development and reduced quality of life, is an overlooked entity among children and adolescents. Vestibular evoked myogenic potential (VEMP) is a common, safe diagnostic tool in adults with vestibular disorders. No normative data exist for children and adolescents. Our objective was to collect and assess normative VEMP data for adolescents. METHODS Cervical VEMP (cVEMP) with air-conducted sound. Endpoints were peak latencies after 13 and 23 ms (P13 and N23) and amplitude. Ocular VEMP (oVEMP) with bone-conducted vibration on the mastoid. Endpoints were latencies (N10 and P15) and amplitude. A meta-analysis of existing cVEMP data in children. RESULTS cVEMP response rate (RR) was 85%, mean P13 and N23 latencies were 15.44 and 25.55 ms, respectively, and the asymmetry ratio (AR) was 14%. oVEMP RR was 100%, mean N10 and P15 were 10.61 and 16.58 ms, respectively, and the AR was 12%. In the meta-analysis, the pooled mean P13 and N23 were 12.75 and 21.8 ms, respectively. Head elevation (HE) gave shorter latencies than head rotation (HR). CONCLUSION The oVEMP data represents normal values for adolescents aged 13-16 years. Height should be considered more important than age when interpreting cVEMP in adolescents. Separate normative cVEMP data should be established for HE and HR.

Abstract
INTRODUCTION Objective of the study is to define rates of successful completion of components of pediatric vestibular testing (VT). METHODS Retrospective review of VT performed on patients less than 18 years of age from 2004 to 2015. RESULTS 188 pediatric patients (mean age: 13.9 ± 3.56 years old, range 2-17 years) underwent testing. Thirty-five (18.6%) had abnormal test results. Pediatric patients unable to complete all aspects of VT could still complete an average of 7.9 ± 4.0 of 12 test components. The optokinetic tracking test was the most commonly omitted component of the vestibular tests. In a multivariate analysis, failure to perform Nylen-Barany positional testing (χ2 27.5, p < 0.0001) or Dix-Hallpike (5.66, p = 0.0174) testing was associated with inability to obtain final diagnosis on VT. CONCLUSIONS Interpretable VT may be obtained in most children, even in those that do not tolerate the full testing protocol. Spontaneous and gaze-evoked nystagmus testing maybe considered as part of initial testing protocol before attempting less well-tolerated components such as bithermal calorics or components that require VNG goggles.

Abstract
The growing evidence of the need for pediatric vestibular evaluation, as well as the availability of successful treatment options for children, is attracting the attention of many professionals and sparking much interest in the development of pediatric balance centers in North America. Complete balance function assessment and rehabilitation in children requires specialized knowledge and practices of professionals in multiple disciplines. While individual specialists provide useful test information and recommendations for patients, the collaboration of specialists working in a multidisciplinary fashion allows the information to become more powerful, providing the patients and their families with a comprehensive plan. Currently, there are only a handful of pediatric balance centers in North America and most of the centers have been in existence less than 10 years. Thus, this new initiative is in its infancy. Educating oneself, administrators, referral sources, and interdisciplinary colleagues is crucial for gathering support for the enormous endeavor of developing such a center. There are many resources one can draw from, including the works found in this issue. Our hope is that this special Seminars in Hearing may serve as a companion guide to anyone interested in performing pediatric vestibular evaluations and/or developing a multidisciplinary pediatric balance center.

Abstract
Quantitative tests of vestibular function include the caloric test, cervical and ocular vestibular evoked myogenic potential (VEMP), rotary chair, and head impulse test, either at the bedside or utilizing video head impulse test (vHIT). The purpose of this article is to provide an overview of how to perform these tests in children, including which tests are recommended based on the child's age and any modifications or considerations that can be made. A variety of clinical measures have been recommended as screening measures for vestibular loss, which will be reviewed. Symptom questionnaires designed to assess the functional impact of dizziness and vestibular loss in children will also be discussed. If a child complains of dizziness or if vestibular loss is suspected (either by case history or positive screening measure), vestibular function testing is warranted. For vestibular function testing, children aged 0 to 2 years typically receive rotary chair, cervical VEMP, and vHIT if a remote system is available. For children aged 3 to 7 years, vHIT, cervical VEMP, and ocular VEMP are completed, and for children aged 8+ years, vHIT, caloric testing if vHIT is normal, and cervical and ocular VEMP are completed. For all children, modifications to testing can be made, as needed.

Abstract
The purpose of this study was to report the prevalence of vestibular impairment (VI) in children ( n = 2,528) referred for complete vestibular testing because of balance disorders (BD) or hearing loss (H). A VI was shown in 51.5% of the children tested (1,304/2,528). For BD (e.g., vertigo, dizziness, instability, delay in posturomotor development), VI was found in 36.5% ( n = 379/1,037). The most frequent causes of BD with VI included inner ear malformation (13.5%), delay in posturomotor development (13.4%), hearing loss revealed with vertigo (3.9%), trauma (3.9%), vestibular neuritis (3.3%), meningitis (2.5%), Meniere-like syndrome (1.1%), BPPV posttrauma (1%), labyrinthitis (0.4%), and unknown etiology (19.6%). Normal responses to the complete battery of tests ( n = 658, 63.5%) excluded a vestibular origin to BD, leading to other diagnoses: principally migraine (15.6%), ophthalmological disorders (15.1%), neurological disorders (including delay in posturomotor development; 14.4%), orthostatic hypotension, or somatoform dizziness (<1%). Of the children referred for hearing loss ( n = 1,491), 68.5% were tested without cochlear implantation (CI; n = 1,022). In this group, 54.5% presented with VI ( n = 557). This was mostly found in cytomegalovirus infection, inner ear malformation, and genetic syndromes. Profound hearing loss candidates for cochlear implants had complete bilateral vestibular loss in 20% and delay in posturomotor development, and 80% had partial or normal vestibular function and normal posturomotor development. VI was found after CI in 50% on the side of the implant (partial in 41% and complete in 9%). VI is present in 36.5% of children referred to our center for BDs and 54.5% for hearing loss. Vestibular testing permits ruling out peripheral VI and hence seeking other causes for BDs such as migraine and ophthalmological disorders and also helps lower the risk of inducing bilateral complete vestibular loss in CI protocols.

Abstract
INTRODUCTION Some studies have demonstrated a parallelism between the extent of hearing loss and the frequency of vestibular dysfunction in children with sensorineural hearing loss (SNHL). Despite this, little is known about the repercussion of degrees of hearing loss and etiological factors on the balance performance in this children. OBJECTIVE Compare the balance performance between normal hearing (NH) children and those with SNHL, considering the sex and age range of the sample, and analyze balance performance according to the degrees of hearing loss and etiological factors in the latter group. METHODS Cross-sectional study that assessed 96 children (48 NH and 48 with SNHL), aged between 7 and 18 years old. The balance performance was assessed by the Brazilian version of the Pediatric Balance Scale, validated for Brazilian child population and the Mann-Whitney test used for statistical analysis. RESULTS The group with SNHL showed lower average balance performance compared to NH (p = 0.000). This was also observed when the children were grouped by sex: female and male (p = 0.001). The same difference occurred when the children were stratified by age group: 7-14 years old (p = 0.000). There were no differences between the balance performance of the groups according to the degrees of hearing loss (p = 0.236) and the children with prematurity or post-natal meningitis as an etiological factor demonstrated the worst balance performance. CONCLUSION The children with SNHL showed worse balance performance compared to NH of the same sex and age range between seven to fourteen years. There were no differences between balance performance and hearing loss degrees, and those children with prematurity or post-natal meningitis as an etiological factor demonstrated the worst balance performances.

Abstract
BACKGROUND Otitis media with effusion (OME) is one of the most common clinical conditions in childhood. Fluid accumulation in the middle ear may impact inner ear. OBJECTIVES The purpose of this random sample cohort study was to investigate whether the past history of middle ear effusion has a long-term negative impact on the vestibular system in children. MATERIAL AND METHODS The study was carried out on 22 children aged 7-15 years who had undergone drainage of the middle ear 5 years before evaluation. The control group consisted of 29 healthy children aged 4-17 years. Vestibular function was examined using sway posturography and electronystagmography (ENG). RESULTS The stabilogram parameters of the study group and the control group were compared. The field of developed area (FDA) and the average body sway velocity (ASV) were analyzed. Elevated stabilogram parameters of FDA and ASV, both with eyes open and eyes closed, were found in the study group. Statistically significant values (p < 0.05) were present for ASV with eyes open and with eyes closed. The ENG recordings were analyzed in both groups. In the study group, spontaneous nystagmus was observed in 40.9% of the children and positional nystagmus occurred in 63.6% of the children. According to tests, eye tracking test was impaired in 27.3% of cases. Rotatory chair testing revealed asymmetry in 18.2% of the children. CONCLUSION The presence of effusion in the middle ear in the past has a negative impact on the vestibular part of the inner ear. Clinicians should be aware of the possible negative impact of middle ear effusion on the vestibular function in children with a history of otitis media with effusion. With seeimingly asymptomatic children clinicians should inquire parents about symptoms of dysequlibrium and imbalance.

Abstract
BACKGROUND The Vestibular/Ocular Motor Screening (VOMS) measure is a newly developed vestibular and ocular motor symptom provocation screening tool for sport-related concussions. Baseline data, psychometric properties, and reliability of the VOMS are needed to further understand the applications of this tool, especially in the youth population, where research is scarce. PURPOSE To establish normative data and document the internal consistency and false-positive rate of the VOMS in a sample of nonconcussed youth athletes. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS A total of 423 youth athletes (male = 278, female = 145) between the ages of 8 and 14 years completed baseline VOMS screening before the start of their respective sport seasons. Internal consistency was measured with Cronbach α and inter-item correlations. RESULTS Approximately 60% of youth athletes reported no symptom provocation on baseline VOMS assessment, with 9% to 13% scoring over the cutoff levels (score of ≥2 for any individual VOMS symptom, near point convergence distance of ≥5 cm). The VOMS displayed a high internal consistency (Cronbach α = .97) at baseline among youth athletes. CONCLUSION The current findings provide preliminary support for the implementation of VOMS baseline assessment into clinical practice, due to a high internal consistency, strong relationships between VOMS items, and a low false-positive rate at baseline in youth athletes.

Abstract
BACKGROUND Cervical and ocular vestibular-evoked myogenic potentials (VEMPs) have become common clinical vestibular assessments. However, VEMP testing requires high intensity stimuli, raising concerns regarding safety with children, where sound pressure levels may be higher due to their smaller ear canal volumes. PURPOSE The purpose of this study was to estimate the range of peak-to-peak equivalent sound pressure levels (peSPLs) in child and adult ears in response to high intensity stimuli (i.e., 100 dB normal hearing level [nHL]) commonly used for VEMP testing and make a determination of whether acoustic stimuli levels with VEMP testing are safe for use in children. RESEARCH DESIGN Prospective experimental. STUDY SAMPLE Ten children (4-6 years) and ten young adults (24-35 years) with normal hearing sensitivity and middle ear function participated in the study. DATA COLLECTION AND ANALYSIS Probe microphone peSPL measurements of clicks and 500 Hz tonebursts (TBs) were recorded in tubes of small, medium, and large diameter, and in a Brüel & Kjær Ear Simulator Type 4157 to assess for linearity of the stimulus at high levels. The different diameter tubes were used to approximate the range of cross-sectional areas in infant, child, and adult ears, respectively. Equivalent ear canal volume and peSPL measurements were then recorded in child and adult ears. Lower intensity levels were used in the participant's ears to limit exposure to high intensity sound. The peSPL measurements in participant ears were extrapolated using predictions from linear mixed models to determine if equivalent ear canal volume significantly contributed to overall peSPL and to estimate the mean and 95% confidence intervals of peSPLs in child and adult ears when high intensity stimulus levels (100 dB nHL) are used for VEMP testing without exposing subjects to high-intensity stimuli. RESULTS Measurements from the coupler and tubes suggested: 1) each stimuli was linear, 2) there were no distortions or nonlinearities at high levels, and 3) peSPL increased with decreased tube diameter. Measurements in participant ears suggested: 1) peSPL was approximately 3 dB larger in child compared to adult ears, and 2) peSPL was larger in response to clicks compared to 500 Hz TBs. The model predicted the following 95% confidence interval for a 100 dB nHL click: 127-136.5 dB peSPL in adult ears and 128.7-138.2 dB peSPL in child ears. The model predicted the following 95% confidence interval for a 100 dB nHL 500 Hz TB stimulus: 122.2-128.2 dB peSPL in adult ears and 124.8-130.8 dB peSPL in child ears. CONCLUSIONS Our findings suggest that 1) when completing VEMP testing, the stimulus is approximately 3 dB higher in a child's ear, 2) a 500 Hz TB is recommended over a click as it has lower peSPL compared to the click, and 3) both duration and intensity should be considered when choosing VEMP stimuli. Calculating the total sound energy exposure for your chosen stimuli is recommended as it accounts for both duration and intensity. When using this calculation for children, consider adding 3 dB to the stimulus level.

Abstract
PURPOSE The aim of this study was to determine if there are factors that can predict whether a child with hearing loss will also have vestibular loss. METHOD A retrospective chart review was completed on 186 children with hearing loss seen at Boys Town National Research Hospital for vestibular testing from 1999 to 2015 through neurosensory genetics clinic or cochlear implant candidacy. Each child's medical chart was reviewed to obtain the following data: vestibular loss severity (classified as normal, bilateral, or mild to moderate), degree of hearing loss (bilateral pure-tone average [PTA]), imaging abnormalities (classified as "normal" or "abnormal"), parental concerns for gross motor delay (classified as "yes, there is concern" or "no, there is not a concern"), parent report of age when their child sat (months) and walked independently (months), comorbidities (classified as "yes" if there were 1 or more comorbidities or "no" if there were no comorbidities), and score on the Developmental Profile-3. RESULTS Children were grouped according to vestibular loss severity; 115 children had normal vestibular function, 31 had bilateral vestibular loss, and 40 had mild-to-moderate vestibular loss. As severity of vestibular loss increased, children (a) sat and walked later, (b) scored more poorly on the Developmental Profile-3 physical subscale, (c) had more severe hearing loss, (d) had parents who more frequently reported concern for gross motor delay, and (e) were more likely to have other comorbidities. Of these factors, age-to-sit, age-to-walk, PTA, and parental concerns for gross motor developmental delay had the greatest ability to differentiate children with vestibular loss from children with normal vestibular function. For age-to-sit, using a cutoff value of 7.25 months yielded a sensitivity of 62% and a specificity of 81%. For age-to-walk, a cutoff value of 14.5 months yielded a sensitivity of 78% and a specificity of 77%. For PTA for the neurosensory genetics group, a cutoff value of 40 dB yielded a sensitivity of 80% and a specificity of 55%; however, a cutoff value of 66 dB yielded a sensitivity of 33% and an improved specificity of 91%. CONCLUSIONS A referral for vestibular evaluation should be considered for children whose hearing loss is greater than 66 dB and particularly those who sit later than 7.25 months or walk later than 14.5 months or whose parents report concerns for gross motor development. Collectively, these factors appear to be more sensitive for identifying children with bilateral vestibular loss compared with children with mild-to-moderate vestibular loss. Because of the benefit of physical therapy, children identified with vestibular loss should then be referred to physical therapy for further evaluation and treatment.

Abstract
OBJECTIVES Hearing-impaired children are at risk for vestibular damage and delayed motor development. Two major causes of congenital hearing loss are cytomegalovirus (CMV) infection and connexin (Cx) 26 mutations. Comparison of the motor performance and vestibular function between these specific groups is still underexplored. The objective of this study was to investigate the impact of congenital (c)CMV and Cx26 on the motor performance and vestibular function in 6 months old infants. DESIGN Forty children (mean age 6.7 months; range 4.8 to 8.9 months) participated in this cross-sectional design and were recruited from the Flemish CMV registry. They were divided into five age-matched groups: normal-hearing control, asymptomatic cCMV, normal-hearing symptomatic cCMV, hearing-impaired symptomatic cCMV, and hearing-impaired Cx26. Children were examined with the Peabody Developmental Motor Scales-2 and cervical vestibular-evoked myogenic potential (cVEMP) test. RESULTS Symptomatic hearing-impaired cCMV children demonstrated a significantly lower gross motor performance compared with the control group (p = 0.005), the asymptomatic cCMV group (p = 0.034), and the Cx26 group (0.016). In this symptomatic hearing-impaired cCMV group, 4 out of 8 children had absent cVEMP responses that were related to the weakest gross motor performance. The Cx26 children showed no significant delay in motor development compared with the control children and none of these children had absent cVEMP responses. CONCLUSIONS The weakest gross motor performance was found in symptomatic hearing-impaired cCMV-infected children with absent cVEMP responses. These results suggest that abnormal saccular responses are a major factor for this delayed motor development, although more work is needed including comprehensive vestibular function testing to verify this.

Abstract
OBJECTIVES To assess potential risk factors for vertigo and dizziness in adolescents and to evaluate their variability by different vertigo types. The role of possible risk factors for vertigo and dizziness in adolescents and their population relevance needs to be addressed in order to design preventive strategies. STUDY DESIGN The study population consisted of 1482 school-children between the age of 12 and 19 years, who were instructed to fill out a questionnaire on different vertigo types and related potential risk factors. The questionnaire specifically asked for any vertigo, spinning vertigo, swaying vertigo, orthostatic dizziness, and unspecified dizziness. Further a wide range of potential risk factors were addressed including gender, stress, muscular pain in the neck and shoulder region, sleep duration, migraine, coffee and alcohol consumption, physical activity and smoking. RESULTS Gender, stress, muscular pain in the neck and shoulder region, sleep duration and migraine were identified as independent risk factors following mutual adjustment: The relative risk was 1.17 [1.10-1.25] for female sex, 1.07 [1.02-1.13] for stress, 1.24 [1.17-1.32] for muscular pain, and 1.09 [1.03-1.14] for migraine. The population attributable risk explained by these risk factors was 26%, with muscular pain, stress, and migraine accounting for 11%, 4%, and 3% respectively. CONCLUSION Several established risk factors in adults were also identified in adolescents. Risk factors amenable to prevention accounted for 17% of the total population risk. Therefore, interventions targeting these risk factors may be warranted.

Abstract
AIMS The functional reach test (FRT) and lateral reach test (LRT) provide important measures of postural stability. The aims of this study were to (1) establish the normative values for FRT and LRT, and (2) examine the effects of age, gender, and various anthropometric measurements on FRT and LRT. METHODS Two hundred eighty children, aged 6-12 years, completed the study. One hundred fifty-two subjects were females. The mean age was 9.0 ± 2.0 years. Each child performed two trials of FRT and LRT. RESULTS No significant differences were detected in any age group between males and females. The normal values of FRT ranged between 23.0 and 36.5 cm, and that of LRT between 18.0 and 28.0 cm. Height, length of upper and lower extremity, and arm span had a higher correlation with FRT. Age and weight showed a good correlation with FRT. Age, height, weight, length of upper and lower extremity, and arm span showed good correlation with LRT. CONCLUSIONS These normative data will be useful for clinicians in the assessment of balance of individual children and in the diagnosis of potential balance deficits at an early age in the Turkish population.

Abstract
STUDY DESIGN Case report. BACKGROUND Dizziness is a common and debilitating condition across the lifespan. Patients with this complaint must be carefully examined to determine the cause of dizziness, rule out the presence of central nervous system dysfunction, and determine the appropriateness of physical therapy intervention. CASE DESCRIPTION A 90-year-old male was referred to physical therapy six months after the onset of dizziness. A thorough history was taken and examination was performed. Signs consistent with central nervous system dysfunction and peripheral vestibular dysfunction were observed. The patient was treated for the peripheral vestibular disorder and referred back to his physician for further testing. Imaging revealed that the patient had idiopathic normal pressure hydrocephalus. DISCUSSION This case illustrates the need for physical therapists to perform thorough examinations of patients with a primary complaint of dizziness and properly interpret positive central signs, indicating a potential need for referral to a physician or other healthcare provider when they appear.

Abstract
OBJECTIVES Children differ from adults in the expression of dizziness symptoms and the causes of dizziness. In several studies, benign paroxysmal vertigo of childhood (BPVC) and vestibular migraine (VM) were seen exclusively in children with vertigo, but the age threshold used to define 'children' varies, and there are few reported studies about adolescents with dizziness. In this study, we investigated the prevalence of vestibular and balance disorders according to age category in a multi-center study (otolaryngology departments of 11 hospitals) of children and adolescents. METHODS Children and adolescents aged under 18 who visited the otolaryngology departments of 11 hospitals for dizziness were included. We classified the patients into three categories: preschool (up to and including 6-year-olds), school age (7- to 12-year-olds), and adolescents (13- to 18-year-olds). These patients were reviewed retrospectively based on their clinical charts. RESULTS In the preschool age group, BPVC was most common, followed by VM. In the school-age group, BPVC and VMs were most common, followed by psychogenic vertigo and benign paroxysmal positional vertigo (BPPV). In adolescents, VM was the most common, and Ménière's disease, cardiogenic vertigo, and BPVC, which are seen primarily in adults, were also seen in some adolescents. CONCLUSION In children and adolescents with dizziness, VM and BPVC were the most common diseases, and prevalence of disease by age showed differing distributions. These findings will help in diagnosing and managing children and adolescents with vertigo.

Abstract
BACKGROUND Uncompensated vestibular hypofunction results in postural instability, visual blurring with head movement, and subjective complaints of dizziness and/or imbalance. We sought to answer the question, "Is vestibular exercise effective at enhancing recovery of function in people with peripheral (unilateral or bilateral) vestibular hypofunction?" METHODS A systematic review of the literature was performed in 5 databases published after 1985 and 5 additional sources for relevant publications were searched. Article types included meta-analyses, systematic reviews, randomized controlled trials, cohort studies, case control series, and case series for human subjects, published in English. One hundred thirty-five articles were identified as relevant to this clinical practice guideline. RESULTS/DISCUSSION Based on strong evidence and a preponderance of benefit over harm, clinicians should offer vestibular rehabilitation to persons with unilateral and bilateral vestibular hypofunction with impairments and functional limitations related to the vestibular deficit. Based on strong evidence and a preponderance of harm over benefit, clinicians should not include voluntary saccadic or smooth-pursuit eye movements in isolation (ie, without head movement) as specific exercises for gaze stability. Based on moderate evidence, clinicians may offer specific exercise techniques to target identified impairments or functional limitations. Based on moderate evidence and in consideration of patient preference, clinicians may provide supervised vestibular rehabilitation. Based on expert opinion extrapolated from the evidence, clinicians may prescribe a minimum of 3 times per day for the performance of gaze stability exercises as 1 component of a home exercise program. Based on expert opinion extrapolated from the evidence (range of supervised visits: 2-38 weeks, mean = 10 weeks), clinicians may consider providing adequate supervised vestibular rehabilitation sessions for the patient to understand the goals of the program and how to manage and progress themselves independently. As a general guide, persons without significant comorbidities that affect mobility and with acute or subacute unilateral vestibular hypofunction may need once a week supervised sessions for 2 to 3 weeks; persons with chronic unilateral vestibular hypofunction may need once a week sessions for 4 to 6 weeks; and persons with bilateral vestibular hypofunction may need once a week sessions for 8 to 12 weeks. In addition to supervised sessions, patients are provided a daily home exercise program. DISCLAIMER These recommendations are intended as a guide for physical therapists and clinicians to optimize rehabilitation outcomes for persons with peripheral vestibular hypofunction undergoing vestibular rehabilitation.Video Abstract available for more insights from the author (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A124).

Abstract
Vestibular end organ impairment is highly prevalent in children who have sensorineural hearing loss (SNHL) rehabilitated with cochlear implants (CIs). As a result, spatial perception is likely to be impacted in this population. Of particular interest is the perception of visual vertical because it reflects a perceptual tilt in the roll axis and is sensitive to an imbalance in otolith function. The objectives of the present study were thus to identify abnormalities in perception of the vertical plane in children with SNHL and determine whether such abnormalities could be resolved with stimulation from the CI. Participants included 53 children (15.2 ± 4.0 years of age) with SNHL and vestibular loss, confirmed with vestibular evoked myogenic potential (VEMP) testing. Testing protocol was validated in a sample of nine young adults with normal hearing (28.8 ± 7.7 years). Perception of visual vertical was assessed using the static Subjective Visual Vertical (SVV) test performed with and without stimulation in the participants with cochleovestibular loss. Trains of electrical pulses were delivered by an electrode in the left and/or right ear. Asymmetric spatial orientation deficits were found in nearly half of the participants with CIs (24/53 [45%]). The abnormal perception in this cohort was exacerbated by visual tilts in the direction of their deficit. Electric pulse trains delivered using the CI shifted this abnormal perception towards center (i.e., normal; p = 0.007). Importantly, this benefit was realized regardless of which ear was stimulated. These results suggest a role for CI stimulation beyond the auditory system, in particular, for improving vestibular/balance function.

Abstract
OBJECTIVES There is a high incidence of vestibular loss in children with cochlear implants (CCI). However, the relationship between vestibular loss and various outcomes is unknown in children. The objectives of this study are to (1) determine whether age-related changes in peripheral vestibular tests occur; (2) quantify peripheral vestibular function in children with normal hearing and CCI; and (3) determine whether amount of vestibular loss predicts visual acuity and balance performance. DESIGN Eleven CCI and 12 children with normal hearing completed the following tests of vestibular function: ocular and cervical vestibular-evoked myogenic potential to assess utricle and saccule function and the video head impulse test to assess semicircular canal function. The relationship between amount of vestibular loss and the following balance and visual acuity outcomes was assessed: dynamic gait index, single-leg stance, the sensory organization test, and tests of visual acuity, including dynamic visual acuity and the gaze stabilization test. RESULTS (1) There were no significant age-related changes in peripheral vestibular testing with the exception of the n23 cervical vestibular-evoked myogenic potential latency, which was moderately correlated with age. (2) CCI had significantly higher rates of vestibular loss for each test of canal and otolith function. (3) Amount of vestibular loss predicted performance on single-leg stance, the dynamic gait index, some conditions of the sensory organization test, and the dynamic visual acuity test. Age was also a contributing factor for predicting the performance of almost all outcomes. CONCLUSIONS Preliminarily, children with vestibular loss do not recover naturally to levels of their healthy peers, particularly with activities that utilize vestibular input; they have poorer visual acuity and balance function.

Abstract
OBJECTIVE To study national prevalence of dizziness and balance problems in US children and explore associated risk factors and patterns of healthcare utilization. STUDY DESIGN A multistage, nationally representative, probability sample of children (n = 10,954; aged 3-17 years) was examined based on the 2012 National Health Interview Survey Child Balance Supplement. Parents were asked if during the past year their child was bothered by symptoms of dizziness and balance problems: vertigo (motion sensation), light-headedness/fainting, clumsiness/poor coordination, poor balance/unsteadiness when standing-up or walking, frequent falls, or other dizziness and balance problems. Logistic regression was used to examine associations with sociodemographic information, birth weight, developmental delays, and significant health conditions. RESULTS Prevalence of dizziness and balance problems was 5.3% (3.3 million US children); females, 5.7%, males, 5.0%. Non-Hispanic white (6.1%) had increased prevalence compared with Hispanic (4.6%) and non-Hispanic black (4.3%) children, P = .01. Prevalence increased with age, from 4.1% for children aged 3-5 years to 7.5% for children aged 15-17 years, P < .001. Even though the majority had symptoms rated as "no problem" or "a small problem," 18.6% (600,000 US children) had symptoms rated as "moderate," "big," or "very big" problems. Overall, 36.0% of children with dizziness and balance problems were seen by healthcare professionals during the past year and 29.9% received treatment. Among children with dizziness and balance problems rated as moderate/big/very big problems, 71.6% had seen healthcare professionals and 62.4% received treatment for dizziness and balance problems. CONCLUSIONS The risk factors identified provide useful epidemiologic information about dizziness and balance problems in children and will be used in tracking the Healthy People 2020 goal to increase utilization of healthcare services for these children.

Abstract
BACKGROUND Congenital cytomegalovirus (cCMV) infection is the most important etiology of non-hereditary childhood hearing loss and an important cause of neurodevelopmental delay. The current study aimed to investigate the early motor development of symptomatic and asymptomatic cCMV infected children with and without sensorineural hearing loss (SNHL). METHODS Sixty-four children with a cCMV infection, without cerebral palsy, were compared to a control group of 107 normal hearing children. They were assessed around the ages of 6, 12, and 24 months with the Peabody Developmental Motor Scales-2 (PDMS-2), Alberta Infant Motor Scales (AIMS), and Ghent Developmental Balance Test (GDBT). The cCMV infected children were subdivided into a symptomatic (n=26) and asymptomatic cCMV group (n=38) but also into a cCMV group with SNHL (n=19) and without SNHL (n=45). RESULTS Symptomatic cCMV infected children and cCMV infected children with SNHL performed significantly weaker for all gross motor outcome measures. CONCLUSION A congenital CMV infection is a risk factor for a delay in the early motor development. Follow-up will be necessary to gain insight into the exact cause of this motor delay and to define the predictive value of early motor assessment of cCMV infected children.

Abstract
This chapter gives an overview of the epidemiology of dizziness, vertigo, and imbalance, and of specific vestibular disorders. In the last decade, population-based epidemiologic studies have complemented previous publications from specialized settings and provided evidence for the high burden of dizziness and vertigo in the community. Dizziness (including vertigo) affects about 15% to over 20% of adults yearly in large population-based studies. Vestibular vertigo accounts for about a quarter of dizziness complaints and has a 12-month prevalence of 5% and an annual incidence of 1.4%. Its prevalence rises with age and is about two to three times higher in women than in men. Imbalance has been increasingly studied as a highly prevalent complaint particularly affecting healthy aging. Studies have documented the high prevalence of benign paroxysmal positional vertigo (BPPV) and vestibular migraine (VM), as well as of comorbid anxiety at the population level. BPPV and VM are largely underdiagnosed, while Menière's disease, which is about 10 times less frequent than BPPV, appears to be overdiagnosed. Risk factor research is only at its beginning, but has provided some interesting observations, such as the consistent association of vertigo and migraine, which has greatly contributed to the recognition of VM as a distinct vestibular syndrome.

Abstract
OBJECTIVE To develop and validate the Pediatric Vestibular Symptom Questionnaire (PVSQ) and quantify subjective vestibular symptom (ie, dizziness, unsteadiness) severity in children. STUDY DESIGN One hundred sixty-eight healthy children (female, n = 91) and 56 children with postconcussion dizziness or a vestibular disorder (female, n = 32), between ages 6 and 17 years, were included. The PVSQ contains questions regarding vestibular symptom frequency during the previous month. The Strengths and Difficulties Questionnaire (SDQ), a brief behavioral screening instrument, was also completed. RESULTS The PVSQ showed high internal consistency (10 items; Cronbach α = 0.88). A significant between-group difference was noted with higher (ie, worse) PVSQ scores for children with vestibular symptoms (P < .001); no significant differences were noted between patient groups. The optimal cut-off score for discriminating between individuals with and without abnormal levels of vestibular symptoms was 0.68 out of 3 (sensitivity 95%, specificity 85%). Emotional and hyperactivity SDQ subscale scores were significantly worse for patients compared with healthy participants (P ≤ .01). A significant relationship was noted between mean PVSQ and SDQ (parent-rated version) hyperactivity and total scores for patients (P ≤ .01) and the SDQ (self-rated) emotional, hyperactivity, and total score (P ≤ .01) in healthy controls. However, mean SDQ subscale and total scores were within normal ranges for both groups. CONCLUSIONS Self-reported vestibular symptoms, measured by the PVSQ, discriminated between children presenting with vestibular symptoms and healthy controls and should be used to identify and quantify vestibular symptoms that require additional assessment and management.

Abstract
PURPOSE The purpose of the present investigation was to develop a psychometrically sound dizziness disability/handicap outcome measure for use with a pediatric population between 5 and 12 years of age. METHODS Items comprising Phase 1 of the DHI-PC were created based on reports from parents, providers and patients. This version was administered to the caregivers (mean age 31.6 years, sd 5 years, 74 female) of 86 pediatric patients (mean age 9 years, sd=2.83 years, 45 female). The caregiver's responses to each item were limited to "yes" (scored as 4 points), "sometimes" (scored as 2 points) or "no" (scored as zero points). RESULTS A factor analysis for Phase 1 of the scale showed there to be a single factor (eigenvalue of 11.51) that explained 29% of the total variance. The results of Cronbach's alpha analysis enabled us to eliminate 15 items reducing the scale to 25 items (i.e. Phase 2 of the DHI-PC). Following elimination of the items with low item-total coefficients, the second phase of the DHI-PC was administered to 56 legal guardians (mean patient age 8 years, sd 4.65 years, 37 female). The analysis of this data again showed there to be a single factor (eigenvalue of 8.30) that explained 33% of the variance. Four items demonstrated item-total correlations less than 0.40. The final version of the DHI-PC has 21 items and a maximum score of 84%. Short-term test-retest reliability (i.e. three week interval between test and retest) of this DHI-PC was assessed for a subset of 10 patients (caregivers, mean age 38 years, sd=7 years, 10 female). The results indicated the short-term, test-retest reliability to be strong (r=0.98, p≤0.001). CONCLUSION The DHI-PC represents a new tool for assessing the impact of pediatric dizziness on the patient (as viewed through the perspective of the caregiver). This tool may be incorporated into the comprehensive evaluation of children suffering from dizziness.

Abstract
Background Vertigo/Dizziness in childhood is not a rare cause of visits to the emergency department (ED). We analyzed a selected group with vertigo/dizziness to identify signs and symptoms that may help to guide the diagnostic approach and management. Methods A total of 616 children admitted for vertigo to the ED over a five-year period were retrospectively reviewed. Their medical history, clinical characteristics, laboratory and neuroimaging tests, final diagnoses and management were analyzed. Results Migraine and syncope were the most frequent causes. Two patients were affected by life-threatening cardiac syncope, while structural life-threatening central nervous system diseases were found in 15 patients, none of whom presented with vertigo as an isolated clinical finding. Conclusions Most cases of vertigo/dizziness in childhood that consist mainly of migraine and syncope are of benign origin. The prompt identification of neurological or cardiological signs or symptoms associated with vertigo in children is mandatory to rule out life-threatening conditions.

Video head impulse testing (VHIT) in the pediatric population. Int J Pediatr Otorhinolaryngol 2015; 79:1283-7. [PMID: 26066850 DOI: 10.1016/j.ijporl.2015.05.033] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2015] [Revised: 05/12/2015] [Accepted: 05/16/2015] [Indexed: 11/23/2022]
Abstract
OBJECTIVES VHIT is the first vestibular test to evaluate all six semicircular canals. This test has advantages over the rotary chair and caloric tests in evaluating children since it does not require fear-inducing darkness or provocation of dizziness. The goal of this study was to review our initial experience with VHIT in children and adolescents at a pediatric vestibular program. METHODS Results using the ICS Impulse VHIT device in 33 patients <20 years of age were retrospectively reviewed. Rotary chair testing was used to designate 26 subjects into groups with normal (n=20) and abnormal (n=6) lateral semicircular canal (LSC) function for comparison. RESULTS Ages ranged from 3 to 19 years (mean 13±4.3) with no statistically significant difference in mean lateral canal gains between age groups (3-10, 11-14, 15-19 years, respectively) by one-way ANOVA, p=0.111. LSC VHIT gain of <0.7 demonstrated sensitivity of 66.7%, specificity of 100%, positive predictive value of 100%, negative predictive value of 90.9% for detecting abnormal LSC function. Corrective saccades demonstrated 100% sensitivity and 100% specificity for detecting abnormal LSC function. VHIT gain <0.7 in an anterior (n=7) or posterior (n=9) canal was only found in subjects with a clinical history and abnormal findings on other tests indicative of a diagnosis involving the affected canal (e.g. benign paroxysmal positioning vertigo, vestibular neuritis, etc.). CONCLUSION VHIT is an effective test for evaluating semicircular canal function in children and offers major potential advantages over rotary chair and caloric testing.

Abstract
OBJECTIVE To characterize the prevalence and recovery of pediatric patients with concussion who manifest clinical vestibular deficits and to describe the correlation of these deficits with neurocognitive function, based on computerized neurocognitive testing, in a sample of pediatric patients with concussion. METHODS This was a retrospective cohort study of patients ages 5-18 years with concussion referred to a tertiary pediatric hospital-affiliated sports medicine clinic from July 1, 2010 to December 31, 2011. A random sample of all eligible patient visits was obtained, and all related visits for those patients were reviewed. RESULTS A total of 247 patients were chosen from 3740 eligible visits for detailed review and abstraction; 81% showed a vestibular abnormality on initial clinical examination. Those patients with vestibular signs on the initial examination took a significantly longer time to return to school (median 59 days vs 6 days, P=.001) or to be fully cleared (median 106 days vs 29 days, P=.001). They additionally scored more poorly on initial computerized neurocognitive testing, and it took longer for them to recover from neurocognitive deficits. Those patients with 3 or more previous concussions had a greater prevalence of vestibular deficits, and it took longer for those deficits to resolve. CONCLUSION Vestibular deficits in children and adolescents with a history of concussion are highly prevalent. These deficits appear to be associated with extended recovery times and poorer performance on neurocognitive testing. Further studies evaluating the effectiveness of vestibular therapy on improving such deficits are warranted.

Abstract
OBJECTIVE Evaluation and management of vertigo in children vary between institutions and medical specialties. The aim of this study is to describe the characteristics of vertigo in children presenting to a pediatric neurology referral center and to investigate the relationship between vertigo and migraine. STUDY DESIGN Patients <18 years old presenting with vertigo to Hacettepe University Ihsan Dogramaci Children's Hospital Neurology Unit between January 1996-January 2012 were included (n = 100). Data were obtained from patient files and phone interviews. RESULTS Mean age was 7.5 years. The most common etiological groups were benign paroxysmal vertigo of childhood (BPVC) (39%), psychogenic vertigo (21%), epileptic vertigo (15%), and migraine-associated vertigo (MAV) (11%). BPVC was the most common diagnosis in children ≤5 years of age while psychogenic vertigo prevailed in children >5 years. Staring episodes characterized epileptic vertigo patients (p = 0.021) while headache was more often described by MAV patients (p < 0.001). Vertigo attacks >5 min were uncommon in BPVC patients compared to others (p = 0.013). Twenty percent of BPVC patients contacted through phone interviews were experiencing migraine type headaches that started at a median age of 7.5 years. An algorithm for evaluation of children with vertigo was formed based on data obtained from this study and the literature. When this algorithm was applied to 100 cases of this series, 88 (88%) were correctly diagnosed. CONCLUSION While most vertigo cases in children can be diagnosed accurately by a detailed medical history, physical and neurological examination, a standard algorithm can help with the correct classification.

Abstract
Although much of children's motor skills have a heredity component, at least half of the variance is likely to be influenced by the environment. It is important to ascertain features of the environment that are responsible so that toxins can be avoided, children at risk can be identified, and beneficial interventions initiated. This review outlines the results of published studies and recommends the areas where further research is required. We found much confusion with little comparability concerning the ages or measures used. Few studies had sufficient power and few allowed for confounders. We found that research to date implicates associations with prenatal drinking ≥4 drinks of alcohol per day; diabetes; taking antidepressant drugs; being deficient in iodine or iron; dietary fish; and postnatal depression. The child appearing to be most at risk was born of low birth weight (but not due to preterm delivery) or with neonatal problems.

Abstract
OBJECTIVES To systematically review and discuss the main pathologies associated with vertigo and dizziness in children, paying particular attention to recent advances in diagnosis and therapy. METHODS One appropriate string was run on PubMed to retrieve articles dealing with the topics mentioned above. A cross-check was performed on citations and full-text articles found using the selected inclusion and exclusion criteria. A non-comparative meta-analysis concerning the rate of singular vertiginous forms was performed. RESULTS Ten articles were identified comprising a total of 724 subjects. Overall, the articles we analyzed indicated benign paroxysmal vertigo of childhood (18.7%) and migraine-associated vertigo (17.6%) as the two main entities connected with vertigo and dizziness in children. Head trauma (14%) was the third most common cause of vertigo. The mean (95% CI) rate of every vertiginous form was also calculated in relation to the nine studies analyzed with vestibular migraine (27.82%), benign paroxysmal vertigo (15.68%) and vestibular neuritis (9.81%) being the three most common forms. There appeared to be a paucity of recent literature concerning the development of new diagnostic methods and therapies. CONCLUSIONS On the basis of the literature study, when evaluating a young patient with vertigo and dizziness, the otolaryngologist should be aware that, in children, these symptoms are often connected to different pathologies in comparison to the entities observed in the adult population.

Abstract
PURPOSE To determine reliability, diagnostic values, and minimal detectable change scores, 90% confidence (MDC90) of pediatric clinical tests of vestibular function. METHODS Twenty children with severe to profound bilateral sensorineural hearing loss and 23 children with typical development, aged 6 to 12 years, participated. The Head Thrust Test, Emory Clinical Vestibular Chair Test, Bucket Test, Dynamic Visual Acuity, Modified Clinical Test of Sensory Interaction on Balance, and Sensory Organization Test were completed twice for reliability. Reference standard diagnostic tests were rotary chair and vestibular evoked myogenic potential. Reliability, sensitivity, specificity, predictive values, likelihood ratios, and MDC90 scores were calculated. RESULTS Reliability ranged from an intraclass correlation coefficient of 0.73 to 0.95. Sensitivity, specificity, and predictive values, using cutoff scores for each test representing the largest area under the curve, ranged from 63% to 100%. The MDC90 for Dynamic Visual Acuity and Modified Clinical Test of Sensory Interaction on Balance were 8 optotypes and 16.75 seconds, respectively. CONCLUSIONS Clinical tests can be used accurately to identify children with vestibular hypofunction.

Abstract
As part of the National Institutes of Health Toolbox initiative, we developed a low-cost, easy-to-administer, and time-efficient test of vestibular and visual function. A computerized test of dynamic visual acuity (cDVA) was used to measure the difference in visual acuity between head still and moving in yaw. Participants included 318 individuals, aged 3 to 85 years (301 without and 17 with vestibular pathology). Adults used Early Treatment of Diabetic Retinopathy Study (ETDRS) optotypes; children used ETDRS, Lea, and HOTV optotypes. Bithermal calorics, rotational chair, and light box testing were used to validate the cDVA. Analysis revealed that the cDVA test is reliable for static (intraclass correlation coefficient [ICC] >/= 0.64) and dynamic (ICC >/= 0.43-0.75) visual acuity. Children younger than 6 years old were more likely to complete cDVA with Lea optotypes, but reliability and correlation with ETDRS was better using HOTV optotypes. The high correlation between static acuity and light box test scores (r = 0.795), significant difference of cDVA scores between those with and without pathology (p </= 0.04), and the good to excellent sensitivity (73%) and specificity (69%) establish that the cDVA is a valid and reliable measure of visual acuity when the head is still and moving, as well as a good proxy of vestibular function to yaw rotation.

Abstract
Objectives. To describe the characteristics and outcome of vertigo in a pediatric population. Patients. All children and adolescents presenting with vertigo to a tertiary otoneurology clinic between the years 2003–2010 were included in the study. Results. Thirty-seven patients with a mean age of 14 years were evaluated. The most common etiology was migraine-associated vertigo (MAV) followed by acute labyrinthitis/neuritis and psychogenic dizziness. Ten patients (27%) had pathological findings on the otoneurological examination. Abnormal findings were documented in sixteen of the twenty-three (70%) completed electronystagmography evaluations. Twenty patients (54%) were referred to treatment by other disciplines than otology/otoneurology. A follow-up questionnaire was filled by twenty six (70%) of the study participants. While all patients diagnosed with MAV had continuous symptoms, most other patients had complete resolution. Conclusions. Various etiologies of vertigo may present with similar symptoms and signs in the pediatric patient. Yet, variable clinical courses should be anticipated, depending on the specific etiology. This is the reason why treatment and follow up should be specifically tailored for each case according to the diagnosis. Close collaboration with other medical disciplines is often required to reach the correct diagnosis and treatment while avoiding unnecessary laboratory examinations.
