title: [Measure of the slow phase angular speed by the trigonometric method].
abstract: We compare trigonometric and traditional systems for nystagmus slow phase speed measures. Results are detailed in Table I. Mean difference between both procedures is 0.88 +/- 0.51 degree/sec. so we conclude that trigonometric system is a reliable method for these measures.
