Abstract
Twenty normal persons were studied by elec-tronystagmography (ENG) for spontaneous, positional, and caloric nystagmus. In addition, a pendulum test was performed. Spontaneous nystagmus was demonstrated in 3 persons. Another 6 had positional nystagmus in 1-4 positions, with a maximum angular velocity of 7.5/scc. The parameters (duration, frequency, and angular velocity) after caloric stimulation were analysed statistically. The duration parameter showed least relative standard deviation. There was no sign of a correlation between sex, age, and the data measured. No abnormal curves were found in the pendulum test. On the basis of examples of centrally and peripherally conditioned nystagmus, the pendulum test appears well-suited for distinguishing between these types of nystagmusKeywords
