We aimed to determine the diagnostic value of electronystagmography (ENG) in a community-based sample of dizzy subjects over 65 years old. A total of 96 asymptomatic controls and 149 dizzy subjects underwent ENG. Clinical diagnoses were made on standardized criteria. ENG results were classed as normal or abnormal, according to reference ranges derived from the controls. Rates of ENG abnormality in different diagnostic categories, sensitivities, specificities and predictive values were calculated. Central vascular disease was common (105 out of 149 subjects); peripheral vestibular disease was not (14). Spontaneous nystagmus had a positive predictive value of 95% for central vascular disease, but was only 18%-sensitive, and was usually detectable clinically. ENG had no other significant diagnostic value. ENG failed to discriminate dizzy subjects from controls and failed to differentiate various dizziness syndromes. ENG was of no practical value in this community-derived sample of dizzy elderly subjects.
我们旨在确定眼震电图（ENG）在65岁以上社区头晕患者样本中的诊断价值。共有96名无症状对照者和149名头晕患者接受了ENG检查。根据标准化标准做出临床诊断。ENG结果根据对照组得出的参考范围分为正常或异常。计算了不同诊断类别中ENG异常的发生率、敏感性、特异性和预测值。中枢血管疾病很常见（149名受试者中有105名）；外周前庭疾病则不然（14名）。自发性眼震对中枢血管疾病的阳性预测值为95%，但敏感性仅为18%，且通常在临床上可检测到。ENG没有其他显著的诊断价值。ENG无法区分头晕患者和对照者，也无法区分各种头晕综合征。在这个来自社区的头晕老年患者样本中，ENG没有实际价值。
