About this study
Official title: Vestibular ASsessment In Children - Balance Function in Normal Children and Specific Risk Groups (VASIC)
The goal of this age-based cohort 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. The participants will be children in the age of 6 months to 10 years, without any known hearing or balance problems. The test protocol consists of questionnaires, hearing screening and vestibular and postural assessments.
Read the detailed description
Balance problems in children are an overlooked issue in the Danish healthcare system. Dysfunction of the vestibular system, i.e. vestibular dysfunction (VD), can have significant consequences for children's development and quality of life.
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
video Head Impulse TestDiagnostic test
Also called vHIT
For v-HIT, the Synapsys v-HIT Ulmer device is used.
Cervical Vestibular Evoked Myogenic PotentialDiagnostic test
Also called cVEMP
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 PotentialDiagnostic test
Also called oVEMP
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 PosturographyDiagnostic test
Also called CDP
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 caregiversOther
Also called DHI-PC
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Children, Only and Vestibular Function, run by Gødstrup Hospital at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 11 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Signe F Bønløkke, PhD student (+4541405064, siband@rm.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
video Head Impulse Test (vHIT) (time frame: Measured at baseline.). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2026.
