尽管需要评估敏感性以进行准确的诊断，并且需要记录在术后期间实现的感觉程度，但临床医生一直没有准确测量人的压力感知的能力。 传统上，Semmes-Weinstein单丝用于测量静态单点辨别阈值。 使用一种新的感觉测试仪器，压力感知感觉装置，从35名年龄从16岁到83岁没有已知神经功能障碍的人的优势手的食指和小指获得规范性数据。 记录静态单点和两点辨别力（s1 PD，s2 PD）和运动单点和两点辨别力（m1 PD，m2 PD）的压力感觉。 食指上的s1 PD、s2 PD、m1 PD和m2 PD的平均值（+/-SD）分别为0.13 +/- 0.06、0.24 +/- 0.12、0.22 +/- 0.10和0.26 +/- 0.13 gm/mm 2，食指上的s1 PD、s2 PD、m1 PD和m2 PD的平均值（+/-SD）分别为0.07 +/- 0.05、0.16 +/- 0.12、0.26 +/-0.13 gm/mm 2。小指的s1 PD、s2 PD、m1 PD和m2 PD分别为0.17 ± 0.07和0.21 ± 0.14 gm/mm 2。 小指的敏感性显著高于食指（p < 0.001）。 随着年龄的增长，压力感知没有显着变化。
Despite the need to evaluate sensibility for accurate diagnosis and the need to record the degree of sensation achieved in the postoperative period, the clinician has been without the ability to measure human pressure perception accurately. Traditionally, the Semmes-Weinstein monofilaments were used to measure the static one-point discrimination threshold. A new sensory testing instrument, the Pressure-Specifying Sensory Device, was used to obtain normative data from the index and little finger of the dominant hand in 35 people ranging in age from 16 to 83 with no known neurologic impairment. Pressure perceptions for static one- and two-point discrimination (s1PD, s2PD) and moving one- and two-point discrimination (m1PD, m2PD) were recorded. The mean values (+/-SD) were 0.13 +/- 0.06, 0.24 +/- 0.12, 0.22 +/- 0.10, and 0.26 +/- 0.13 gm/mm2 for s1PD, s2PD, m1PD, and m2PD, respectively, on the index finger and 0.07 +/- 0.05, 0.16 +/- 0.12, 0.17 +/- 0.07, and 0.21 +/- 0.14 gm/mm2 for s1PD, s2PD, m1PD, and m2PD, respectively, for the little finger. The little finger was significantly more sensitive than the index finger (p < 0.001). There was no significant change in pressure perception with increasing age.
