Vestibular evaluation of infants and preschool children
Insights
Vestibular testing using harmonic acceleration (HA) in children aged 3 months to 6 years showed no significant maturational differences between full-term and premature infants. This study refined HA methods for pediatric vestibular evaluation.
Area of Science:
- Pediatric Vestibular Assessment
- Auditory and Vestibular Sciences
- Child Communication Disorders
Background:
- Vestibular function assessment is crucial for diagnosing balance disorders in children.
- Established vestibular testing protocols require adaptation for pediatric populations.
- Boys Town National Institute has experience in modifying vestibular tests for children.
Purpose of the Study:
- To present updated vestibular test modifications used at the Boys Town National Institute.
- To report results of vestibular evaluations in a pediatric cohort.
- To investigate age-related maturational differences in vestibular function in infants.
Main Methods:
- Utilized harmonic acceleration (HA) for vestibular evaluations.
- Evaluated 104 children (3 months to 6 years), including premature infants and postmeningitic patients.
- Adapted infrared video technology for continuous head and eye monitoring in a darkened enclosure.
Main Results:
- No age-related maturational differences were found in harmonic acceleration (HA) gain, phase, or symmetry at 0.08 Hz.
- Comparison between full-term and premature infants revealed no significant differences.
- Infrared video monitoring provided continuous visual data during testing.
Conclusions:
- Harmonic acceleration (HA) testing is reliable for assessing vestibular function in young children, irrespective of prematurity.
- The adapted HA methodology and video monitoring enhance pediatric vestibular assessment.
- Findings support the use of HA for evaluating vestibular function in diverse pediatric groups.
Abstract:
This article presents an updated summary of vestibular test modifications employed at the Boys Town National Institute for Communication Disorders in Children. In addition, we report the results of vestibular evaluations of 104 full-term and premature children (47 male and 57 female) ranging in age from 3 months to 6 years, including a group of postmeningitic patients. The evaluations utilized harmonic acceleration (HA). No age-related maturational differences in HA gain, phase, or symmetry for an 0.08 Hz screening frequency were found when full-term and premature infants were compared. Infrared video technology was adapted to provide continuous visual monitoring of head and eye position in the totally darkened test enclosure.
