We adopted the estimate of the intraclass coefficient of reliability, R, to evaluate the reliability of smooth pursuit eye movement quantitative analysis. At a one-week interval, we recorded twice smooth pursuit eye movements from fifteen healthy subjects by means of the binocular electrooculographic technique. R was computed for the constant and the slope of the target velocity/gain relationships. R values were rated good for the slope and excellent for the constant. Finally, we computed for each parameter the maximum variability value according to two differing methods; on the basis of the within-subjects mean square values, we defined the normal range of biological test-retest variability for the two parameters.
我们采用组内相关系数R来评估平稳跟踪眼球运动定量分析的可靠性。在一周的间隔时间内，我们通过双眼眼电图技术对15名健康受试者的平稳跟踪眼球运动进行了两次记录。计算了目标速度/增益关系的常数和斜率的R值。R值对于斜率评定为良好，对于常数评定为优秀。最后，我们根据两种不同方法计算了每个参数的最大变异性值；基于受试者内均方值，我们定义了这两个参数生物重测变异性的正常范围。
