Abstract：
To characterize differences in vestibular testing results among patients presenting with balance-related complaints; to stratify patterns of testing abnormalities by age.
Retrospective chart review.
Academic Balance Center at a Tertiary Referral Center.
All patients who underwent vestibular testing in a 1-year period from 2017 to 2018.
Balance function test results.
We reviewed 1,116 patients with age ranging from 11 to 94 years, including 521 patients ≥60 years. Most patients had at least 1 abnormal result, with only 21% of patients ≥60 years and 43% of patients <60 years yielding no test abnormalities (p < 0.001). Among 754 individuals with abnormal testing results, caloric testing did not show any significant difference between age groups. Patients ≥60 years of age were more likely to demonstrate abnormalities on saccadic and horizontal tracking eye movements (p < 0.01; sacc 20.8% vs 6.3%; HT 9.2% vs 4.7%), as well as positional and Dix-Hallpike testing with videonystagmography (p < 0.001; pos 52.3% vs 37.5%, DH 14.4% vs 6.8%). On computerized dynamic posturography, there were significantly more abnormal composite scores in the older group for both sensory organization and motor control testing (p < 0.001; SOT 31.8% vs 8.8%, MCT 7.6% vs 1.8%).
Among patients presenting balance-related complaints, a majority demonstrate at least one abnormality on vestibular testing. While caloric abnormalities occur across the life span, patients ≥60 years of age are more likely to have abnormal results in random saccades, positional, Dix-Hallpike testing, and posturography, with greater effect sizes in tests of central function. While the causes of imbalance and vertigo remain multifactorial, vestibular dysfunction can be considered a major contributor to balance dysfunction in the elderly population and should be thoroughly evaluated.

摘要：
描述患有平衡相关主诉的患者前庭测试结果的差异；按年龄对测试异常的模式进行分层。
回顾性图表回顾。
第三级转诊中心的学术平衡中心。
在2017年至2018年的1年内接受前庭检查的所有患者。
平衡功能测试结果。
我们回顾了1,116名年龄在11至94岁之间的患者，包括521例≥60岁的患者。大多数患者至少有1个异常结果，只有21%的≥60岁的患者和43%的<60岁的患者没有检测异常(p<0.001)。在754名检测结果异常的人中，热量测试未显示年龄组之间的任何显着差异。年龄≥60岁的患者更有可能在扫视和水平跟踪眼动方面表现出异常（p<0.01；sacc20.8％vs6.3％；HT9.2％vs4.7％），以及带有视频眼震描记术的位置和Dix-Hallpike测试（p<0.001；pos52.3％vs37.5％，DH14.4%对6.8%）。关于计算机动态姿势描记术，在感觉组织和运动控制测试中，老年组的综合评分异常明显（p<0.001；SOT31.8％vs8.8％，MCT7.6%对1.8%）。
在出现平衡相关投诉的患者中，大多数在前庭测试中至少有一个异常。虽然在整个生命周期中都会发生热量异常，年龄≥60岁的患者更有可能在随机扫视中出现异常结果，位置,Dix-Hallpike测试,和姿势描记术,在中心功能测试中具有更大的效果大小。虽然失衡和眩晕的原因仍然是多方面的，前庭功能障碍可被认为是老年人群平衡功能障碍的主要原因，应进行全面评估。
