The goal of this prospective cohort study is to investigate the vestibular function in children with unilateral or bilateral sensorineural hearing loss. The main hypothesis of the study is that abnormal vestibular test results will be found in 20-30 % of the children with sensorineural hearing loss. The participants will be children in the age of 3-10 years with sensorineural hearing loss. The test protocol consists of questionnaires and vestibular and postural assessments.
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.
In particular, children with sensorineural hearing loss are at risk of developing VD. Hence, VD has been reported in 14 % to 91 % of children with sensorineural hearing loss. The close anatomical and embryological relationship between the hearing system and the vestibular system may of course explain this correlation.
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 investigate the vestibular function in children with unilateral or bilateral sensorineural hearing loss.
Hypothesis: The investigators expect that abnormal vestibular test results will be found in 20-30 % of the children with sensorineural hearing loss.
Methods: The study is a prospective cohort study. Participants are a prospective, unselected group of children in the age of 3-10 years with either unilateral or bilateral sensorineural hearing loss. The participants are recruited at The Audiologic Clinic at Viborg Regional Hospital, Denmark.
All participants will go through a test protocol consisting of questionnaires and vestibular and postural assessments.
The primary endpoints are results of v-HIT, c and oVEMP, and posturography, which are compared to normative values. The secondary endpoints are prevalence of vestibular dysfunction 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.
170 studies on the registry are indexed under Vestibular Diseases; 41 are open to participants now.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

For v-HIT, the Synapsys v-HIT Ulmer device is used.

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.

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.

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.
