One hundred sixty-six youngsters (3 to 19 years of age) with severe-to-profound hearing impairments underwent vestibular evaluations with electronystagmography as part of a comprehensive medical and psychoeducational test battery. Twenty-two percent of the children had unilateral or bilateral labyrinthine weakness in response to caloric stimulation, and 21% demonstrated spontaneous or positional nystagmus. The tandem Romberg test was most predictive of those patients with caloric labyrinthine weakness. The performance of mental alerting tasks (using sign language when appropriate) by the patients during testing proved essential in overcoming a marked tendency toward central suppression of nystagmus.
166名3至19岁的重度至极重度听力障碍青少年接受了眼震电图前庭评估，这是综合医学和心理教育测试组合的一部分。22%的儿童对冷热刺激有单侧或双侧迷路功能减退，21%表现出自发性或位置性眼球震颤。串联罗姆伯格试验对那些冷热迷路功能减退的患者预测性最强。测试过程中患者执行心理警觉任务（必要时使用手语）对于克服眼球震颤明显的中枢抑制倾向至关重要。
