AIMS
A new pressure algometer was used to quantify the pressure-pain threshold (PPT) in the human tongue.
METHODS
A custom-made device controlled by software and a personal computer was used to measure the PPT in the anterior part of the tongues of 14 young, healthy subjects. The PPT was measured at 3 different rates of pressure application on 3 occasions, 1 week apart. Data were evaluated with analysis of covariance and intraclass correlations.
RESULTS
The prototype device had linear output characteristics within the operational range. The mean PPT ranged from 18 to 44 g. The PPT appeared to increase approximately linearly with increasing rate of pressure application (P < 0.001). There were no significant differences in the PPT on different experimental occasions. In individual subjects, the PPT was reliable and uniform. There were significant inter-subject differences in the PPT (P < 0.001).
CONCLUSION
The PPT can be measured consistently in the anterior part of the tongue, provided the pressure rate is controlled. The new-pressure algometer appears to have potential clinical utility for quantifying sensation in the human tongue.
目的
使用一种新型压力痛觉计对人类舌头的压力疼痛阈值（PPT）进行量化。
方法
使用由软件和个人计算机控制的定制设备，对14名年轻健康受试者舌头前部的PPT进行测量。在三种不同的压力施加速率下，分三次测量PPT，每次间隔1周。数据采用协方差分析和组内相关性进行评估。
结果
该原型设备在工作范围内具有线性输出特性。平均PPT范围为18至44克。PPT似乎随着压力施加速率的增加而近似线性增加（P < 0.001）。不同实验场合下的PPT没有显著差异。在个体受试者中，PPT是可靠且一致的。受试者之间的PPT存在显著差异（P < 0.001）。
结论
只要控制好压力速率，就可以在舌头前部持续测量PPT。这种新型压力痛觉计似乎在量化人类舌头感觉方面具有潜在的临床应用价值。
