vHIT can be used to successfully measure the function of the lateral SCC in children as young as 4 years of age. Our results provide normative gain values that can be used when testing children with lateral vHIT. Care must be taken to obtain the most accurate measures and reduce variability when testing children, particularly with LARP and RALP. Our data would suggest that lower gain cutoffs should be used for LARP and RALP testing in children than the cutoffs used for lateral vHIT. Further research is warranted to study LARP and RALP response reliability and validity in children because of the highly variable VOR gains found in this population. Pediatric modifications for successfully administering vHIT and obtaining reliable results are discussed.
