An Analog Technique for Nystagmus Display

An Analog Nystagmus Analyser for Clinical Routine

“…Torok and N ykiel (18) measured automatically the rate o f nys tagmus beats in the caloric test. By an analog technique, Voots (19) and McClure et al (12) determined the cumulative slow-phase displacements, which, in turn, allowed them to derive the slow-phase velocity. As an average value, Voots gives the slow-phase displacement in a 10-sec interval.…”
