256 patients with postural vertigo were examined clinically and neurootologically. Positioning nystagmus (PN) was detected in 209 (81.6%) of them. Postural vertigo arose as a result of inner ear diseases or traumas (n = 52), affection of cervical spine (n = 24), cardiovascular diseases (n = 97), organic impairment of the posterior cranial fossa (n = 20), endocrine disorders (n = 5), intoxication from chronic infection foci (n = 24), neuroses with vegetative dysfunction (n-34). PN emerged, as a rule, in patients having 2-3 of the above conditions. A genesis scheme of PN is outlined with regard to interaction of the main pathogenic factors influencing the vestibular system. Horizontal-rotatory or rotatory, vertical, diagonal, bilateral horizontal or multiple PN are characteristic for peripheral vestibular dysfunctions and central vestibular dysfunction, respectively. It is reasonable to perform position tests after assessment of the patients' nervous and cardiovascular systems, the condition of cervical spine.
对256例姿势性眩晕患者进行了临床和神经耳科学检查。其中209例（81.6%）检测到位置性眼震（PN）。姿势性眩晕由内耳疾病或外伤（n = 52）、颈椎病变（n = 24）、心血管疾病（n = 97）、后颅窝器质性损害（n = 20）、内分泌紊乱（n = 5）、慢性感染灶中毒（n = 24）、伴有自主神经功能障碍的神经症（n = 34）引起。PN通常出现在有上述2 - 3种情况的患者中。根据影响前庭系统的主要致病因素之间的相互作用，概述了PN的发生机制。水平旋转或旋转性、垂直性、斜向性、双侧水平性或多发性PN分别是外周前庭功能障碍和中枢前庭功能障碍的特征。在评估患者的神经和心血管系统、颈椎状况后进行位置试验是合理的。
