The threshold to touch was tested in hands and feet of normal persons using Semmes-Weinstein graded monofilament nylons. The minimum stimulus to which response could be elicited was nylon number 3.61 in palms and 4.31 in soles. These numbers relate to the logarithm of the force applied, 3.61 corresponding to 0.217 gm force and 4.31 to 2.35 gm force respectively. The area of pain insensitivity complained by the patient more or less corresponds to that revealed by objective testing. It was interesting to observe that loss of pain sensitivity was confined to a smaller area compared to touch and thermal insensibility in the part innervated by the same nerve trunk.
使用Semmes-Weinstein分级单丝尼龙对正常人的手和脚进行触觉阈值测试。能够引发反应的最小刺激是手掌为3.61号尼龙丝，脚底为4.31号尼龙丝。这些数字与施加力的对数相关，3.61分别对应0.217克力，4.31对应2.35克力。患者主诉的疼痛不敏感区域与客观测试显示的区域大致相符。有趣的是，观察到与由同一神经干支配部位的触觉和热觉不敏感相比，疼痛敏感性丧失局限于较小区域。
