This study investigated the frequency of vestibular disorders in developmentally disabled preschoolers who did and who did not have a history of otitis media. Fifteen children with a history of otitis media and fifteen children with no history of otitis media were given two tests for vestibular functioning: the Southern California Postrotary Nystagmus Test (SCPNT) and the Lateral Labyrinthine Righting Reaction (LLRR), acting on the head. The scores on these tests were dichotomized, and a correlation between these two tests as measures of vestibular function was obtained. Because this correlation did not reach a satisfactory level, two a satisfactory level, two separate chi-square analyses were performed to examine the frequency of vestibular disorders with otitis media. Both tests showed a statistically significant difference in the incidence of vestibular disorders between the two groups of children; the group having otitis media demonstrated more vestibular disorders. The SCPNT demonstrated more striking results than did LLRR. This finding is related to the two tests measuring different aspects of vestibular functioning; the separate chi-square analyses were performed to examine the frequency of vestibular disorders with otitis media. Both tests showed a statistically significant difference in the incidence of vestibular disorders between the two groups of children; the group having otitis media demonstrated more vestibular disorders. The SCPNT demonstrated more striking results than did LLRR. This finding is related to the two tests measuring different aspects of vestibular functioning; the SCPNT reflects semicircular canal functioning, and the LLRR reflects utricular and saccular functioning. The criteria used for LLRR (four seconds) also may have influenced the results obtained using this test.
本研究调查了有中耳炎病史和无中耳炎病史的发育障碍学龄前儿童前庭疾病的发生率。对15名有中耳炎病史的儿童和15名无中耳炎病史的儿童进行了两项前庭功能测试：南加州旋转后眼震试验（SCPNT）和作用于头部的外侧迷路翻正反应（LLRR）。这些测试的分数被二分法处理，并得出这两项测试作为前庭功能指标之间的相关性。由于这种相关性未达到令人满意的水平，因此进行了两项独立的卡方分析，以检查中耳炎患者前庭疾病的发生率。两项测试均显示两组儿童在前庭疾病发生率上存在统计学显著差异；有中耳炎的组表现出更多的前庭疾病。SCPNT的结果比LLRR更显著。这一发现与两项测试测量前庭功能的不同方面有关；SCPNT反映半规管功能，而LLRR反映椭圆囊和球囊功能。LLRR使用的标准（四秒）也可能影响了使用该测试获得的结果。
