Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Knowledge about the prevalence of vestibular impairment and normative data of vestibular function in the Danish pediatric population is missing.
The investigators aim for a child friendly and reliable vestibular test protocol in the study. According to the investigators studies as well as international reports, the investigators have chosen a vestibular test protocol with Video Head Impulse Test (v-HIT), cervical and ocular Vestibular Evoked Myogenic Potential (c and oVEMP) as the tests are feasible, valid, and child friendly. To evaluate overall balance ability, the children are tested on a Computerized Dynamic Posturography.
The aim of the study is to provide normative data of vestibular function in the general Danish pediatric population. Thus, the investigators will be able to compare patient data with norms, allowing for more precise diagnostics.
Methods: The study is an age-based cohort study. Participants are children in the age of 6 months to 10 years, without any known hearing or balance problems. The participants are recruited in local nurseries, kinder gardens, and schools. All participants will go through a test protocol consisting of questionnaires, hearing screening and vestibular and postural assessments.
The primary endpoints are age-based norms for v-HIT, c and oVEMP, and posturographic results. The secondary endpoints are number of subjects with successful results of the vestibular test protocol and mean total Dizziness Handicap Inventory for patient caregivers (DHI-PC) score. A number of variables are collected such as demographics, developmental milestones, family history with focus on hearing and balance.

Healthy children without hearing or balance problems
Healthy children in the age of 6 months to 10 years, without any known hearing or balance problems and with normal gross motor development are recruited in local nurseries, kinder gardens, and schools.
video Head Impulse Test
For v-HIT, the Synapsys v-HIT Ulmer device is used.
Cervical Vestibular Evoked Myogenic Potential
For cVEMP, the Eclipse (Interacoustic, Middelfart, Denmark) is used. To bypass the frequent middle ear problems bone conduction stimuli (B-81, Interacoustic, Middelfart, Denmark) are administrated. The bone conductor is placed on the mastoid process and two trials at 70 dB nHL are conducted to check waveform reproducibility. 500 Hz short tone bursts (2-2-2 ms) are applied at 5 per second stimulus repetition rate.
Ocular Vestibular Evoked Myogenic Potential
For oVEMP, the Eclipse (Interacoustic, Middelfart, Denmark) is used. To bypass the frequent middle ear problems bone conduction stimuli (B-81, Interacoustic, Middelfart, Denmark) are administrated. The bone conductor is placed on the mastoid process and two trials at 70 dB nHL are conducted to check waveform reproducibility. 500 Hz short tone bursts (2-2-2 ms) are applied at 5 per second stimulus repetition rate.
Computerized Dynamic Posturography
To evaluate functional balance of the children and the relative contributions of the vision, proprioception, and vestibular system a CDP from Virtualis (Virtualis, Montpellier, France) is used.
Dizziness Handicap Inventory for patient caregivers
DHI is a caregiver-reported 21-item questionnaire. It is designed to evaluate the perceived quality of life and handicap resulting from dizziness and unsteadiness for the pediatric population. For each question there are three possible answers: yes, sometimes or no. Each answer provides respectively 4, 2 and 0 points. The total DHI scores range from 0 to 84 with higher score being consistent with more limitation and more severe handicap. Scores under 16 are characterized as no limitation or handicap. A score from 16-26 present a mild perceived handicap and mild limitations. A DHI-score between 26-43 is classified as a moderate problem, and a score above 43 describes a severe perceived handicap and severe limitations.
