Tactile thresholds were measured with the focused ultrasound in 21 healthy subjects and 30 patients with various neurological diseases. All patients in spite of the level and origin of the disorder in the tactile--conducting pathways exhibited increased thresholds which were the most evident with 0.1--1 msec stimulus duration. This method allows not only to confirm the disorder of the tactile sensation, but to characterize it quantitatively including "subclinical" degree as well.
在21名健康受试者和30名患有各种神经系统疾病的患者中，使用聚焦超声测量触觉阈值。所有患者，无论触觉传导通路中疾病的程度和起源如何，均表现出阈值升高，在刺激持续时间为0.1 - 1毫秒时最为明显。这种方法不仅可以确认触觉感觉障碍，还可以对其进行定量表征，包括“亚临床”程度。
