Twenty-five emotionally disturbed children were tested on the Lafayette Clinic Cognitive Perceptual Motor (CPM) battery. The children were next examined for vestibular function by measuring ocular nystagmus for three different rotation rates. Under conditions of eye closure, children found to have two or more marked CPM deficits demonstrated a significantly reduced amplitude of postrotatory nystagmus as compared to CPM nondeficit children, and for the slowest rate of rotation (30 degrees/sec), a significantly decreased duration of nystagmus.
对25名情绪失调儿童进行了拉法叶诊所认知感知运动（CPM）成套测试。接下来，通过测量三种不同旋转速率下的眼震来检查这些儿童的前庭功能。在闭眼条件下，与CPM无缺陷儿童相比，被发现有两个或更多明显CPM缺陷的儿童在旋转后眼震的幅度明显降低，并且对于最慢的旋转速率（30度/秒），眼震持续时间明显缩短。
