[Computer analysis of electronystagmograms. First report: the normal pendular test ENG (author's transl)]

In an attempt to standardize the interpretation of electronystagmograms the results of computerized analysis of pendular test nystagmograms have been statistically evaluated. All the nystagmus components show marked dependance on age. The range of normal reactions is determined by means of double standard deviation. The cumulogram of the nystagmus slow phase demonstrates the smallest deviation of all the analysed parameters, and this makes it suitable in the pendular test for diagnostic estimation. The cumulogram provides information on nystagmus slow phase duration, amplitude, symmetry or irregularity.
