本文测定了25例正常人和73例各种前庭周围性疾病患者立位和侧卧位的主观视觉垂直（SV）。前庭神经切断组和Ramsay Hunt综合征组SV明显偏向患耳，前庭神经炎组SV明显偏向患耳（89%），良性阵发性位置性眩晕组SV明显偏向患耳（0%）。SV的偏差逐渐消失，在发病后的几个星期内的疾病在所有患者中，除了在那些与全VII神经切除。SV是类似于前庭自发性眼震的两个前庭之间的紧张性传入差异的参数，但由内耳的其他部分（可能是耳石器官）介导，因此提供了关于前庭功能的额外信息。然而，在90度侧位测量的SV并没有显示不对称的前庭敏感性，这与前庭神经切除术后患者离心旋转期间测试的SV相反。
The subjective visual vertical, SV, was measured in the upright and side positions in 25 normal subjects and in 73 patients with various peripheral vestibular disorders. Significant deviations of SV (toward the affected ear) were found in 100% of the patients with vestibular nerve section and with Ramsay Hunt syndrome, in 89% of the patients with vestibular neuritis, and in 0% of the patients with benign paroxysmal positional vertigo. The deviation of SV gradually disappeared within a few weeks of the onset of the disease in all patients except in those with total VIIth nerve resection. SV is a parameter of tonic afferent differences between the two labyrinths similar to vestibular spontaneous nystagmus but is mediated by other parts of the inner ear (probably the otolith organs) and thus provides additional information on the labyrinthine function. SV measured in 90 degrees side positions, however, did not reveal asymmetric vestibular sensitivity, which is in contrast to SV tested during eccentric rotation in patients after vestibular neurectomy.
