[A simple measuring device for nystagmus amplitude. A contribution to rapid, exact and inexpensive evaluation of electronystagmograms].
Different parameters in use for quantitative analysis of ENG recordings are being discussed. Special importance can be attributed to the slow-phase velocity of the nystagmus and above all to the total amplitude. However, measurement of the total amplitude via digital computers is very expensive. Hence we present a device to measure amplitudes by means of a potentiometer. This is easy to handle, works accurately and is inexpensive.
