BALANCED GROWTH: The Involvement of the Vestibular System in a Child's Cognitive and Motor Development
An observational study of Vestibular Disorder and Neurodevelopmental Disorders, run by University Ghent at 1 site in Belgium.
Trial summary
When a vestibular dysfunction occurs at birth or in early stages of life, one might expect that this may have an enormous impact on a child's development. It is known that a severe congenital or early acquired vestibular deficit in children results in delayed psychomotor milestones. Read more about this study

About this study
When a vestibular dysfunction occurs at birth or in early stages of life, one might expect that this may have an enormous impact on a child's development. It is known that a severe congenital or early acquired vestibular deficit in children results in delayed psychomotor milestones. Later in life, children with a vestibular dysfunction may have difficulties with several balance tasks and additional cognitive, motor and/or psychosocial performances. While a few authors have suggested that there is indeed an influence of a vestibular dysfunction upon these different developmental domains (cognitive, motor, educational and psychosocial development), which can be supported by findings in clinical practice as well, literature concerning this topic remains fairly limited. On the other hand, several studies have shown that children with known difficulties in motor and/or cognitive functions have more difficulties in vestibular performances in comparison with their unaffected peers. Although more frequently discussed, the literature on this population is rather scarce too.
Therefore, the current project aims to investigate the relationship with and the involvement of the vestibular system in the motor and cognitive development of school-aged children.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
When a vestibular dysfunction occurs at birth or in early stages of life, one might expect that this may have an enormous impact on a child's development. It is known that a severe congenital or early acquired vestibular deficit in children results in delayed psychomotor milestones. Later in life, children with a vestibular dysfunction may have difficulties with several balance tasks and additional cognitive, motor and/or psychosocial performances. While a few authors have suggested that there is indeed an influence of a vestibular dysfunction upon these different developmental domains (cognitive, motor, educational and psychosocial development), which can be supported by findings in clinical practice as well, literature concerning this topic remains fairly limited. On the other hand, several studies have shown that children with known difficulties in motor and/or cognitive functions have more difficulties in vestibular performances in comparison with their unaffected peers. Although more frequently discussed, the literature on this population is rather scarce too.
Therefore, the current project aims to investigate the relationship with and the involvement of the vestibular system in the motor and cognitive development of school-aged children.

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 5 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 30 Nov 2023. 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 Belgium. 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 Ruth Van Hecke, Msc (00329 332 22 96, ruth.vanhecke@ugent.be), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
