Longitudinal posturography and rotational testing in children three to nine years of age: normative data.

Abstract

To obtain normative longitudinal vestibulo-ocular and balance test data in children from ages three to nine years with normal middle ear status. Prospective, longitudinal cohort. Tertiary care pediatric hospital. Three-year-old children were entered and tested yearly. Subjects underwent earth vertical axis rotation testing using sinusoidal and constant velocity stimuli and performed the Sensory Organization Test. One hundred forty-eight children were entered, and usable data were collected on 127 children. A linear increase in the vestibulo-ocular reflex gain as children aged was found, without a change in the phase of the response. An age-related linear increase in equilibrium scores, indicating reduced postural sway, was also observed. These normative data can be used in the evaluation of dizziness and balance disorders in children.
