An Age Comparison of the Vestibulo-Ocular Counterroll Reflex.
Abstract
This report examines the relationship between age and a measure considered to be related to static otolith function; vis., the amplitude of ocular counterroll under conditions of static whole body tilts. Amount of counterroll was measured for two groups of subjects (22-34 years, and 50-74 years) to whole body tilts to the right and left. It was found that the young group exhibited more counterroll to tilt than the older group, but this difference was small. In addition, head tilts to the right produced larger counterrolls than tilts to the left in both groups. It is concluded that, because of the considerable variability in the responses from subject to subject, the potential contribution of the static counterroll response to the establishment of age-free biomedical standards is limited.
