To analyze the profiles of pressure pain threshold (PPT) and pressure pain tolerance (PTO) of healthy undergraduates so as to establish the normal reference ranges of PPT and PTO.
The levels of PPT and PTO were measured at lateral brachioradialis of lateral elbow joint with a pressure algometer in 113 healthy undergraduates. Then the influencing factors of tenderness thresholds were analyzed and the normal reference ranges of PPT and PTO established.
The females exhibited a lower PPT than the males (P < 0.01). And the gender differences of PTO were statistically insignificant (P > 0.05). Meanwhile, there was no significant difference in either PPT or PTO between the right and left sides (P > 0.05). The normal reference ranges (kg/cm(2)) of PPT and PTO were obtained at the measuring spot of all subjects. As a result, the ranges of PPT were 1.19 - 4.63 in the males and 0.37 - 3.63 in the females. And the range of PTO was 1.80 - 8.50 in all subjects.
This survey establishes the normal reference ranges of tenderness thresholds at the specific measuring spot for some specific population. These ranges may serve as a reference for the sensitivity of individual tenderness safely, accurately and simply.
分析健康大学生的压力痛阈（PPT）和压力耐痛阈（PTO）特征，以建立PPT和PTO的正常参考范围。
用压力痛觉计测量113名健康大学生肘关节外侧肱桡肌处的PPT和PTO水平。然后分析压痛阈值的影响因素并建立PPT和PTO的正常参考范围。
女性的PPT低于男性（P<0.01）。PTO的性别差异无统计学意义（P>0.05）。同时，左右两侧的PPT和PTO均无显著差异（P>0.05）。在所有受试者的测量点获得了PPT和PTO的正常参考范围（kg/cm²）结果，男性的PPT范围为1.19 - 4.63，女性为0.37 - 3.63。所有受试者的PTO范围为1.80 - 8.50。
本调查建立了特定人群在特定测量点压痛阈值的正常参考范围。这些范围可为安全、准确、简便地评估个体压痛敏感性提供参考。
