About this trial

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.

This trial accepts healthy volunteers

Qualifiers

None

Disqualifiers

Having a (permanent) hearing loss

Having a (permanent) vestibular loss

IQ < 70

Trial population

Typically developing children were used for establishing normative data of the protocol and to achieve objective 2 (convenience sampling; primary schools). Vestibular-impaired patients, established by extensive vestibular assessment for objective 3 (recruited at the Ghent University Hospital). The neurodevelopmental group was needed to establish objective 4 (recruited at schools for special education and/or care facilities).

Trial outcomes

Primary outcomes

1

video Head Impulse Test gain (%)

Gain of the vestibulo-ocular reflex (high frequency function of the three semicircular canals)

Time frame
This parameter will be assessed once during one of both testmoments (the motor/vestibular appointment), and is part of the vHIT assessment (vestibular) which will take 5 minutes.
2

video Head Impulse Test asymmetry (%)

Asymmetry of the vestibulo-ocular reflex between the left en right horizontal/anterior/posterior semicircular canals

Time frame
This parameter will be assessed once during one of both testmoments (the motor/vestibular appointment), and is part of the vHIT assessment (vestibular) which will take 5 minutes.
3

video Head Impulse Test presence of saccades (overt/covert)(n)

Absolute amount of corrective saccades during head impulse testing

Time frame
This parameter will be assessed once during one of both testmoments (the motor/vestibular appointment), and is part of the vHIT assessment (vestibular) which will take 5 minutes.
4

video Head Impulse Test presence of saccades (overt/covert)(% of the performed HITs)

Relative occurance of corrective saccades (with reference to the total amount of performed HITs) during head impulse testing

Time frame
This parameter will be assessed once during one of both testmoments (the motor/vestibular appointment), and is part of the vHIT assessment (vestibular) which will take 5 minutes.

Secondary outcomes

1

Score of the short version (4 subtest form) (Aubry & Bourdin, 2018) of the Wechsler Intelligence Scale for Children-VNL; WISC-V-NL

Estimated intelligence score based on the subtests "matrix reasoning", "similarities", "vocabulary", and "block design"; with a higher score indicating a higher intelligence quotient

Time frame
This parameter will be assessed once during one of both testmoments (the cognitive appointment), and is an outcome parameter of the intelligence assessment which will take 20 minutes.
2

Static visual acuity

The smallest optotype that can be correctly identified while the head is fixed

Time frame
This parameter will be assessed once during one of both testmoments (the motor/vestibular appointment), and is an outcome parameter of the ophtalmologic assessment which will take 5 minutes.
3

Dynamic visual acuity

The smallest optotype that can be correctly identified while moving the head

Time frame
This parameter will be assessed once during one of both testmoments (the motor/vestibular appointment), and is an outcome parameter of the ophtalmologic assessment which will take 5 minutes.
4

The difference between static visual acuity and dynamic visual acuity

This parameter results in the contribution of the vestibulo-ocular reflex during head movements

Time frame
This parameter will be assessed once during one of both testmoments (the motor/vestibular appointment), and is an outcome parameter of the ophtalmologic assessment which will take 5 minutes.
