The purpose of this project was to test the within-day and between-days reproducibility of a new and inexpensive algometer. Twelve symptom-free men and nine women participated. Pressure pain thresholds (PPTs) of the bilateral masseter and temporalis muscles were assessed during four sessions (mornings and afternoons of days 1 and 3). During each session, each palpation point of the masticatory muscles was measured four times. There was an interval of only a few seconds between measurements 1 and 2, and between measurements 3 and 4, respectively, while at least 5 minutes of rest were allowed between measurements 2 and 3. The PPT values between the morning and afternoon sessions and between days 1 and 3 were not significantly different. When the within-session reproducibility for all muscles was considered, only the PPT values between measurements 2 and 4 were not significantly different. Analysis of variance showed that the interindividual variability of PPT was 1.4 to 6.8 times higher than the variability observed within or between sessions and days. No gender difference was found.
本项目的目的是测试一种新型廉价压痛计的日内和日间重复性。12名无症状男性和9名女性参与了研究。在四个时间段（第1天和第3天的上午和下午）评估双侧咬肌和颞肌的压痛阈值（PPT）。在每个时间段内，咀嚼肌的每个触诊点测量4次。测量1和测量2之间以及测量3和测量4之间的间隔仅为几秒，而测量2和测量3之间至少允许休息5分钟。上午和下午时间段之间以及第1天和第3天之间的PPT值无显著差异。当考虑所有肌肉的日内重复性时，仅测量2和测量4之间的PPT值无显著差异。方差分析表明，PPT的个体间变异性比在时间段内、日间或不同天数之间观察到的变异性高1.4至6.8倍。未发现性别差异。
