Three hundred and nine patients, whose chief complaint was dizziness following a flexion-extension type of acceleration neck injury, were examined in the Neurosensory Laboratory of Temple University Health Sciences Center between 1965 and 1972. Specific attention was devoted to vestibular tests, including a search for latent and positional nystagmus, bithermal calorics, and rotatory tests. All tests were performed with the aid of electronystagmography; latent nystagmus was present in 29 percent of the patients, caloric tests were abnormal in 57 percent, and rotatory tests were abnormal in 51 percent. These findings suggest that many of these patients have a verfiable objective vestibular disturbance as a cause of dizziness, even though the neurologic examination may be normal. Furthermore, in order to detect this objective vestibular dysfunction, the patient should be tested with aid of electronystagmography since nystagmus may be inhibited by visual fixation.
1965年至1972年间，在天普大学健康科学中心神经感觉实验室对309例主要因屈伸型加速性颈部损伤后出现头晕的患者进行了检查。特别关注了前庭测试，包括寻找潜在性和位置性眼球震颤、冷热试验以及旋转试验。所有测试均借助眼震电图进行；29%的患者存在潜在性眼球震颤，57%的冷热试验异常，51%的旋转试验异常。这些发现表明，尽管神经系统检查可能正常，但这些患者中有许多人存在可证实的客观性前庭功能障碍，这是头晕的原因。此外，为了检测这种客观性前庭功能障碍，应借助眼震电图对患者进行测试，因为视觉注视可能会抑制眼球震颤。
