糖尿病是一组由于胰腺或代谢功能问题而导致高血糖的代谢性疾病。糖尿病患者的主观症状很少，可能会在不知不觉中出现感觉减退。通常进行的感觉障碍测试本质上是定性的。作者注意到触觉灵敏度的下降，并开发了一种利用形状记忆合金线的新型微振动执行器来检测触觉水平的非侵入性方法。此前，我们进行了一项试点研究，将该设备应用于 15 名糖尿病患者，并证实与健康受试者相比，糖尿病患者的触觉显着降低。在这项研究中，我们重点关注与糖尿病相关的感觉减退的无症状发展。目的是使用定量触觉测量装置检查未意识到感觉异常或减弱的糖尿病患者，并确定与健康对照相比，患者的触觉是否减弱。手指法用于使用新设备测量食指和中指的触觉感觉阈值（TST）得分，并采用以下三个程序：TST-1、TST-4和TST-8。比较两组之间的 TST 评分范围为 1 至 30。糖尿病患者的TST评分显着较高（P < 0.05）。糖尿病患者和健康对照者左手手指的 TST 评分，TST-1 为 5.9 ± 6.2 和 2.7 ± 2.9，TST-4 为 15.3 ± 7.0 和 8.7 ± 6.4，TST-8 为 19.3 ± 7.8 和 12.7 ± 9.1。我们的数据表明，使用新的定量触觉测量装置能够检测糖尿病患者的触觉下降，这些患者与对照组相比没有意识到感觉异常或下降。关键词: 形状记忆合金丝, 微振动模式, 糖尿病, 触觉, 感觉阈值
Diabetes mellitus is a group of metabolic diseases that cause high blood sugar due to functional problems with the pancreas or metabolism. Diabetic patients have few subjective symptoms and may experience decreased sensation without being aware of it. The commonly performed tests for sensory disorders are qualitative in nature. The authors pay attention to the decline of the sensitivity of tactile sensations, and develop a non-invasive method to detect the level of tactile sensation using a novel micro-vibration actuator that employs shape-memory alloy wires. Previously, we performed a pilot study that applied the device to 15 diabetic patients and confirmed a significant reduction in the tactile sensation in diabetic patients when compared to healthy subjects. In this study, we focus on the asymptomatic development of decreased sensation associated with diabetes mellitus. The objectives are to examine diabetic patients who are unaware of abnormal or decreased sensation using the quantitative tactile sensation measurement device and to determine whether tactile sensation is decreased in patients compared to healthy controls. The finger method is used to measure the Tactile Sensation Threshold (TST) score of the index and middle fingers using the new device and the following three procedures: TST-1, TST-4, and TST-8. TST scores ranged from 1 to 30 were compared between the two groups. The TST scores were significantly higher for the diabetic patients (P < 0.05). The TST scores for the left fingers of diabetic patients and healthy controls were 5.9 ± 6.2 and 2.7 ± 2.9 for TST-1, 15.3 ± 7.0 and 8.7 ± 6.4 for TST-4, and 19.3 ± 7.8 and 12.7 ± 9.1 for TST-8. Our data suggest that the use of the new quantitative tactile sensation measurement device enables the detection of decreased tactile sensation in diabetic patients who are unaware of abnormal or decreased sensation compared to controls. key words: shape-memory alloy wires, micro-vibration patterns, diabetes mellitus, tactile sensation, sensory threshold
