Normative Data of Vestibular and Postural Function in Danish Children

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.

Inclusion Criteria: * Children in the age of 6 months -10 years * Normal hearing * No history of dizziness or balance problems * Written informed consent from the parents. Exclusion Criteria: * Premature birth * Existing or previous inner ear disease(s) or previous inner ear surgery * Cholesteatoma or previous middle ear surgery * Known or previous vestibular disorder (Vestibular schwannoma, Mb Meniere, vestibular neuritis or other known) * Delayed gross motor development evaluated through milestones. * Visual impairment to such a degree that the child is not able to maintain fixation on a dot one meter away. * Congenital nystagmus * Compromised eye muscle mobility * A diagnose of any neurological disease. * A diagnose of any psychiatric disease. * VEMP-electrode allergy * History of symptomatic head or neck trauma * Prescription of medicine which alters vestibular outputs (for instance sedative antihistamines)
