A group of 101 otologically normal infants and children were evaluated with low-frequency harmonic acceleration (HA) to determine the feasibility of use of this procedure in evaluation of vestibular function in a pediatric population. Ninety-six of the subjects were successfully tested and normative data are presented. A maturational trend was noted (in the presence of nystagmus) in subjects up to 10 months of age and in the phase-lag measurement up to approximately 4 years of age.
