The Trail Making Test (TMT) is a useful measure of executive dysfunction in elderly subjects. This study aims to investigate the discriminative validity of the oral version of the TMT (OTMT), which can be administered to subjects with visual or motor disabilities, in elderly patients with Mild Cognitive Impairment (MCI; n = 30), Alzheimer's disease (AD; n = 30), and healthy controls (HCs; n = 25). The WAIS-R Digit Span Backwards Subscale, written form of the Trail Making Task, the Clock Drawing Test, the AD Assessment Scale-Cognitive Subscale, and the OTMT were also administered to all participants in order to examine the concurrent validity of the OTMT. The OTMT part B discriminated between patients with MCI, AD, and HC correctly. The OTMT completion time was not correlated with age, but was negatively correlated with education. In conclusion, the OTMT (mostly part B) is a valid and practical measurement tool for different levels of cognitive impairment, especially for patients with visual or motor disabilities for whom the classical written form is not feasible.
连线测验（TMT）是一种用于评估老年人执行功能的有效方法。本研究旨在探讨可用于视力或运动障碍受试者的连线测验口述版（OTMT）的判别效度，该测验用于评估轻度认知障碍（MCI；n=30）、阿尔茨海默病（AD；n=30）和健康对照（HC；n=25）老年患者。韦氏智力测验数字广度倒背分测验、书面形式的连线测验、画钟测验、AD 评估量表认知分量表和 OTMT 也被用于所有参与者，以检验 OTMT 的同时效度。OTMT 部分 B 正确地区分了 MCI、AD 和 HC 患者。OTMT 的完成时间与年龄无关，但与教育程度呈负相关。总之，OTMT（主要是部分 B）是一种针对不同认知障碍程度的有效且实用的测量工具，特别是对于无法进行经典书面形式测试的视力或运动障碍患者。
