Additionally, the latency of the vestibulo-ocular reflex (VOR) has been reported to be as short as 5 to 7 msec.3,4 In contrast, ocular following mechanisms, such as smooth pursuit, generate slower eye velocities (∼60 deg/sec), have relatively long latencies (up to 100 msec),5,6 and fail at frequencies exceeding 1 Hz.7 For subjects with vestibular loss that has not been compensated adequately, head movements can significantly limit participation in activities of daily life.
