Deep pressure pain threshold (PPT) and pressure pain tolerance (PPtol) were measured by pressure algometry at the mastoid processes, external malleoli, and sternum in 24 healthy volunteers. The algometer consisted of a force displacement transducer with a 0.25 cm2 pressure tip linked to a recorder. The rate of force application was approximately 1kg/sec/0.25cm2. High intersubject variation was noted at all sites for both PPT and PPtol. Mean PPT and PPtol values at the sternum were 5.2kg +/- 2.1 and 8.1kg +/- 2.4, respectively, and significantly higher than at the other sites. PTT did not differ significantly between the sexes or between dominant and nondominant sides. PPtol, on the other hand, was lower in the women, but significantly so only at the malleoli. On repeat examination, comparison between the mean values at each site showed no statistical differences in any instance. Pressure algometry, as used in this study in healthy subjects, proved a reliable technique for the estimation of deep PPT and PPtol values. It may possibly serve for screening the response to experimental pain in various groups of pain patients.
在24名健康志愿者的乳突、外踝和胸骨处，通过压力痛觉测定法测量深部压痛阈值（PPT）和压力痛耐受度（PPtol）。痛觉测定仪由一个压力尖端面积为0.25平方厘米的力位移传感器与一台记录仪相连组成。施加力的速率约为1千克/秒/0.25平方厘米。在所有部位，PPT和PPtol的受试者间差异均很大。胸骨处的平均PPT和PPtol值分别为5.2千克±2.1和8.1千克±2.4，显著高于其他部位。PTT在性别之间以及优势侧和非优势侧之间无显著差异。另一方面，女性的PPtol较低，但仅在外踝处差异显著。再次检查时，各部位平均值之间的比较在任何情况下均无统计学差异。本研究中在健康受试者身上使用的压力痛觉测定法，证明是一种用于估计深部PPT和PPtol值的可靠技术。它可能可用于筛查各类疼痛患者对实验性疼痛的反应。
