摘要
目的：调查≥80岁老人的听、前庭及视动功能变化。方法：用纯音测听及听性脑干反应测试听力功能；用眼震电图及姿势图测试半规管、机动及平衡功能。结果：①语频听力异常者占84．1％；②半规管功能和平衡功能异常者分别为38．5％和74．4％，与60岁组比较，重心晃动的轨迹长，速度大；③视动功能检查，≥80岁老人扫视潜伏期延长，跟踪失真度加大。结论：随着年龄老化，≥80老人半规管、视动、平衡功能，均有不同程度减退，可能是老年人易摔倒的重要原因。
Objective:To investigate audio-vestibular and oculomotor functions of octogenarian. Method: Theaudition were measured with audiometry and auditory brainstem response. The semiccular, oculomotor and bal-ance functions were examinated by e lectronys tagmograp hy and posturography. Result: ①The hearing abnormalityof speech frequency were 84. 1 percent by audiometry; ②The abnormal rats of seedircular function and posturo-gram were 38. 5% and 74. 4% respectively. The body sway locus and velocity of octogenarians have increased ascompared with the group of 60 years old in the post urography; ③The latency of saccade was prolongrd and totalhearmonic distortion of pusuit was increased than that of 60 years old in the oculomotor test. Conclusion: Theeasily falling of octogenarians may be related to disturbing of sendcircular oculomotor and equilibrational functions.
