ETT findings in aphasia

Abstract

Smooth pursuit eye movements when tracking sine waveform target movements of 30° amplitude and 1/3 Hz frequency (eye tracking test : ETT) were quantitatively assessed in 18 patients with aphasia.Almost all old aphasic patients, mainly those with cerebro-vascular disorders, showed abnormal values.A few young aphasic patients, mainly those with brain trauma, also had abnormal values. The degree of the eye movement disorder seems to be independent of the degree of aphasia.
