Therapists who evaluate the sensorimotor functions of autistic children have become increasingly interested in monitoring their responses to vestibular stimulation. In this study, the duration of the nystagmus reflex is visually monitored and then measured by means of a stop-watch. Each of 7 autistic subjects received 18 sessions (36 trials) of horizontal semicircular canal stimulation during a period of 25 days. In each trial a graduated acceleration in a hand operated rotating chair preceded an abrupt stop, with a rapid deceleration from 180 degrees/second to 0 degree/second. Although subject option (intentional response) imposes limitations on the data interpretation, inspection of the nystagmus functions over time suggests the following: substantial trial-to-trial variability; substantial subject-to-subject variability; greater scores following trials to the subjects' left (the direction of the second trial in each session) than to the right (the direction of the first); and no evidence of consistent change for most subjects in nystagmus duration across the 36 trials. Implications for clinical evaluation of nystagmus are discussed.
评估自闭症儿童感觉运动功能的治疗师越来越关注监测他们对前庭刺激的反应。在这项研究中，通过肉眼监测眼球震颤反射的持续时间，然后用秒表进行测量。7名自闭症受试者在25天内每人接受了18次（36次试验）水平半规管刺激。在每次试验中，手动旋转椅先进行逐渐加速，然后突然停止，从180度/秒快速减速至0度/秒。尽管受试者的选择（有意反应）对数据解释有一定限制，但随着时间推移对眼球震颤功能的检查表明：试验间存在显著差异；受试者间存在显著差异；受试者向左（每组第二次试验的方向）的试验得分高于向右（第一次试验的方向）；并且大多数受试者在36次试验中眼球震颤持续时间没有一致变化的证据。文中讨论了对眼球震颤临床评估的意义。
