The objective of this work was to evaluate the inter-rater and intra-rater reliability and minimal detectable difference (MDD) of pressure pain thresholds (PPTs) in pain-free participants with two examiners over two consecutive days in a cross-sectional study design. Examiners used a standardized method to measure and locate a specific testing site over tibialis anterior for PPT testing with a hand-held algometer. The mean of each examiner's three PPT measurements was used to calculate the intraclass correlation coefficient, inter-rater reliability, and intra-rater reliability. The minimal detectable difference (MDD) was calculated. Eighteen participants were recruited (11 female). The inter-rater reliability was 0.94 and 0.96 on day 1 and day 2, respectively. Intra-rater reliability for the examiners was 0.96 and 0.92 on day 1 and day 2, respectively. The MDD on day 1 was 1.24 kg/cm (CI: 0.76-2.03) and the MDD on day 2 was 0.88 kg/cm (CI: 0.54-1.43). This study demonstrates high inter- and intra-rater reliability and the MDD values for this method of pressure algometry.
在一项横断面研究设计中，本研究的目的是评估在无痛参与者中，由两名检查者在连续两天内测量压力疼痛阈值（PPTs）时的评分者间和评分者内信度以及最小可检测差异（MDD）。检查者使用标准化方法，通过手持压力痛觉计在胫骨前肌上测量并定位一个特定的测试部位，以进行PPT测试。每位检查者的三次PPT测量结果的平均值用于计算组内相关系数、评分者间信度和评分者内信度。计算最小可检测差异（MDD）。招募了18名参与者（11名女性）。第1天和第2天的评分者间信度分别为0.94和0.96。检查者在第1天和第2天的评分者内信度分别为0.96和0.92。第1天的MDD为1.24 kg/cm（CI：0.76 - 2.03），第2天的MDD为0.88 kg/cm（CI：0.54 - 1.43）。本研究证明了这种压力测痛法的评分者间和评分者内具有高信度以及MDD值。
