本研究的目的是探讨是否可以通过使用一种名为“压力控制触诊”(PCP)的新技术来提高压痛评估的可靠性。这项技术是通过一种新发明的设备实现的，这种设备被称为指压计，通过连接在食指上的压敏塑料薄膜来记录施加的压力。在15名慢性紧张型头痛患者和15名健康志愿者中，2名研究人员使用常规触诊和压力控制触诊研究了肌肉筋膜压痛。在每个被检查的颅骨周围区域，按4分的惊吓评分进行压痛评分。两个观察者使用常规触诊记录的压痛评分总和有显著差异(p=0.0003)，而使用压力控制触诊的观察者之间的结果没有差异(p=0.89)。在七种不同压力强度的触诊中，发现压力与疼痛强度呈线性正相关(p=0.00006)。受试者报告的疼痛强度与观察者的压痛评分高度相关(r(S)=0.95p<；0.0001)。这些结果首次表明，如果触诊压力被控制，观察者之间的压痛评分可以进行比较。压力控制触诊是对当前触诊技术的重大改进，应该成为未来肌肉筋膜疼痛障碍研究的标准。
The objective of the present study was to investigate whether the reliability of tenderness evaluation can be increased by using a new technique called ''pressure-controlled palpation'' (pcp). The technique has been made possible by a newly invented piece of equipment called a palpometer, with which a pressure-sensitive plastic film attached to the index finger records the pressure exerted. In 15 patients with chronic tension-type headache and in 15 healthy volunteers, 2 investigators studied myofascial tenderness using conventional palpation and pressure-controlled palpation. Tenderness was scored on a 4-point scare in each of the examined pericranial regions. The sum of tenderness scores recorded by two observers using conventional palpation differed significantly (p = 0.0003), while results did not differ between observers using pressure-controlled palpation (p = 0.89). During palpation with seven different pressure intensities a positive and linear relation between pressure and pain intensity was found (p = 0.00006). Pain intensity reported by the subjects correlated highly with tenderness scored by the observer (r(s) = 0.95, p < 0.0001). These results demonstrate for the first time that tenderness scores can be compared between observers if palpation pressure is controlled pressure-controlled palpation represents a major improvement on current palpation techniques and should be standard in future research on myofascial pain disorders.
