目的　评价眩晕患者在前庭末梢病变中前庭功能代偿能力。与增龄的关系方法　将 95例一侧前庭功能低下者分为四组 ,Ⅰ组 <30岁 ,Ⅱ组 30～ 49岁 ,Ⅲ组 5 0～ 5 9岁 ,Ⅳ组≥ 6 0岁。对这些病例分别行低频谐波加速度试验和姿态图检查 ,就相位和增益以及总包络面积和长度等指标观察前庭功能的代偿能力。结果　姿态图的正常率为 5 6 % ,低频谐波加速度试验的正常率为 39% ,随年龄的增长 ,患者姿态图正常率逐渐减低。结论　在前庭末梢病变中 ,老年人在前庭眼反射和前庭脊髓反射水平的代偿能力较对照组明显减低 Objective To evaluate the vestibular function compensatory ability in vertigo patients with vertigo. 95 cases of unilateral vestibular dysfunction were divided into four groups, Ⅰ group <30 years old, Ⅱ group 30 to 49 years old, Ⅲ group 50 to 59 years old, Ⅳ group ≥ 60 years old. Perform low-frequency harmonic acceleration tests and attitude map examinations on these cases, and observe the compensatory ability of vestibular function in terms of phase and gain, total envelope area and length. Results The normal rate of attitude map was 56%. The normal rate of low-frequency harmonic acceleration test was 39%. With the increase of age, the normal rate of posture decreased gradually. Conclusion In the vestibular lesions, the compensatory ability of the elderly in the vestibular reflex and the vestibular spinal reflex was significantly lower than that in the control group
