Computer analysis of electronystagmographic data

Manual calculation of the parameters of nystagmus is imprecise and time consuming. Therefore, a computer program for analysis of nystagmus has been built up in our laboratory. The program is based on automatic extraction of the minimum and maximum values nystagmus. These values are stored for calculations of duration, amplitude and velocity of the fast and slow phase. The distinction between the slow and fast phase is based on the duration of the phases. The program is thus able to accept nystagmus in different directions.
