医疗保健的最新进展促进了中风或交通相关伤害患者的生存。然而，此类患者可能会出现较高程度的脑功能障碍；即，根据先验知识计划和执行行为的能力受损。追踪测试（TMT）是一项认知任务，用于评估额叶损伤引起的高级脑功能障碍。 TMT由两个任务组成； TMT-A涉及连续数字连接，TMT-B涉及数字和字母交替连接。在这项研究中，我们利用近红外光谱（NIRS）和成绩值（TMT分数），研究了三个因素对TMT表现的影响：TMT知识、TMT-A和TMT-B表现的顺序以及性别。研究对象为48名健康成年人，包括大学毕业生和本科生（年龄：22.8±2.5岁，文化程度：16.0±1.2岁，男性24名，女性24名）。我们使用 NIRS 测量了氧合血红蛋白 (oxy-Hb) 水平的变化，结果表明，不了解 TMT 的受试者比了解 TMT 的受试者的氧合血红蛋白 (oxy-Hb) 水平增加得更高。在 TMT-A 和 TMT-B 中，执行第一项任务的受试者表现出较高的氧合血红蛋白水平。此外，男性的氧合血红蛋白水平高于女性。相比之下，只有 TMT 表现顺序对 TMT 得分有显着影响。在本研究中，我们使用 NIRS 表明，TMT 知识、TMT 顺序或性别都会影响 TMT 表现，为解释 TMT 结果提供了宝贵的信息。
Recent advances in medical care have facilitated the survival of patients with stroke or traffic-related injuries. However, such patients may suffer from higher brain dysfunction; i.e., an impaired ability to plan and perform behaviors based on prior knowledge. The Trail Making Test (TMT) is a cognitive task that is used to evaluate higher brain dysfunction caused by frontal lobe injury. TMT consists of two tasks; TMT-A involves connecting consecutive numbers, and TMT-B involves connecting numbers and letters alternately. In this study, using near-infrared spectroscopy (NIRS) and the achievement value (TMT score), we investigated the effects of three factors on TMT performance: knowledge of the TMT, the order of TMT-A and TMT-B performance, and gender. The subjects were 48 healthy adults, consisting of college graduates and undergraduates (age: 22.8 ± 2.5 years, education: 16.0 ± 1.2 years, 24 males and 24 females). We measured the changes in oxygenated hemoglobin (oxy-Hb) levels using NIRS, showing that the increase in oxy-Hb was higher in subjects who had no knowledge of the TMT than those who had prior knowledge. In both TMT-A and TMT-B, the subjects who performed their first task displayed higher oxy-Hb levels. Moreover, the oxy-Hb level in males was higher than that in females. In contrast, only the order of TMT performance showed noticeable effect on the TMT score. In the present study, using NIRS we have shown that either knowledge of the TMT, the order of the TMT, or gender affects TMT performance, providing invaluable information for interpreting TMT results.
