目的：探讨眼震电图在前庭功能损伤、代偿及恢复不同阶段的变化特征、相互联系和意义。方法：对１５０例一侧前庭周围性损伤病人进行系列眼震电图试验，并对其中１５例进行至少半年的跟踪观测。结果：在一侧可逆性前庭周围性损伤后，前庭功能存在一个由功能损伤失衡→功能代偿→功能恢复失衡→恢复平衡的复杂病程变化过程。而不可逆性损伤后，前庭功能仅存在由功能损伤失衡→功能代偿的简单病程过程。在不同病程阶段，眼震电图各项结果呈特征性改变，具有多样性、不统一性及表现形式的矛盾性。结论：以全面系统、动态变化的新观点对眼震电图进行综合分析，不但能判断前庭损伤侧别，还可以判定、监测前庭损伤后的病程变化、中枢代偿情况及评估预后，对监测前庭损伤后临床治疗和前庭习服训练有帮助。
OBJECTIVE: To investigate the changes of nystagmography in different stages of vestibular dysfunction, compensatory and recovery, and their relationship and significance. Methods: A series of electronystagmography tests were performed on 150 cases of peripheral unilateral vestibular injury, and 15 cases were followed up for at least six months. Results: After one-sided reversible vestibular circumflex injury, there was a complex process of vestibular function from the imbalance of functional impairment → functional compensation → functional recovery imbalance → recovery balance. Irreversible injury, vestibular function exists only by the functional imbalance → functional compensation of the simple course of the process. In different stages of disease, the results of the electro-acupuncture showed a characteristic change, with the diversity, non-unity and the form of contradiction. Conclusion: A comprehensive and systematic review of the electronystagmography can not only determine the side of the vestibular injury, but also determine and monitor the changes of the course of the vestibular injury, the central compensation and the prognosis of the vestibular injury, Clinical treatment of vestibular injury and vestibular clothing training help.
