The article summarizes updated vestibular test modifications used at the Boys Town National Institute for Communication Disorders in Children. The study evaluated 104 full‑term and premature children aged 3 months to 6 years using harmonic acceleration and infrared video monitoring of head and eye position in a darkened enclosure. No age‑related maturational differences in HA gain, phase, or symmetry at 0.08 Hz were observed between full‑term and premature infants.
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.
