Association between the Unterberger-Fukuda test and vectoelectronystagmography

ABSTRACT Purpose: to study and characterize anteroposterior and angular deviations in the Unterberger-Fukuda Test (UFT) in relation to the results of the caloric tests in patients complaining of dizziness or vertigo. Methods: 44 subjects-men and women between 20 and 79 years of age-who had symptoms of vertigo or dizziness and had been referred for vectoelectronystagmography were examined. The exclusion criteria were gait difficulties arising from orthopedic and/or spinal disorders, and syndromes or neurological diseases that affect balance. Two procedures were performed: vectoelectronystagmography and UFT. Results: the caloric test showed that 25.00% of the patients had hyporeflexia-the most frequent result. In the open-eyes UFT, only 2.30% presented altered results in anteroposterior displacement. In the closed-eyes test, the equivalent value was 31.80%. Anteroposterior deviation showed a greater correlation with age than the angular one. Abnormal results in the caloric test were associated with the UFT. Conclusion: the results of the closed-eyes UFT were associated with the caloric test. Anteroposterior deviation was correlated with age, while angular deviation was not.

摘要
目的：本研究旨在探讨并表征昂伯-福田试验（Unterberger-Fukuda Test, UFT）中的前后向与角度偏移特征，分析其与眩晕或头晕患者前庭冷热试验结果之间的关联。
方法：本研究共纳入44名年龄介于20至79岁的男女受试者，均存在眩晕或头晕症状且被转诊接受矢量眼震电图（vectoelectronystagmography）检查。排除标准包括：由骨科或脊柱疾病引发的步态障碍，以及影响平衡功能的综合征或神经系统疾病。所有受试者均完成两项检查：矢量眼震电图检查与昂伯-福田试验。
结果：前庭冷热试验结果显示，25.00%的患者存在前庭反射减退，此为该试验最常见的异常结果。睁眼昂伯-福田试验中，仅2.30%的受试者出现前后向位移异常；而闭眼昂伯-福田试验中，该异常比例达31.80%。前后向偏移与年龄的相关性强于角度偏移。前庭冷热试验结果异常与昂伯-福田试验结果异常存在关联。
结论：闭眼昂伯-福田试验结果与前庭冷热试验结果存在关联。前后向偏移与年龄呈相关关系，而角度偏移则未表现出此类关联。
