This study was designed to establish the intra-rater and inter-rater reliability of measurements of trigger point sensitivity using a commercially available pressure threshold meter. Fifty healthy adult volunteers (25 men and 25 women, aged 20 to 51 years) underwent repeated pressure threshold readings from two separate trigger point locations in the trapezius muscle, TP2 (left) and TP3 (right) by two independent examiners. Pressure threshold readings, using a 1.0 kg/s application, were done alternately by each experimenter. Measurements from each trigger point were completed 5 minutes apart. Intraclass correlation coefficients (ICC) revealed the inter-rater reliability to be high for both the first (ICC = 0.82) and second trial (ICC = 0.90) of TP2 and for the first (ICC = 0.86) and second trial (ICC = 0.92) of TP3. Intra-rater reliabilities for TP3 (ICC = 0.91) were higher than for TP2 (ICC1 = 0.80; (ICC2 = 0.83). These results show that the pressure threshold meter is highly reliable in measuring trigger point sensitivity, between and within experimenters, and may be useful in the diagnosis and monitoring of treatment of myofascial pain syndrome.
本研究旨在使用市售压力阈值计确定触发点敏感性测量的评分者内信度和评分者间信度。五十名健康成年志愿者（25名男性和25名女性，年龄20至51岁）接受了两名独立检查者对斜方肌中两个不同触发点位置TP2（左侧）和TP3（右侧）的重复压力阈值读数。使用1.0 kg/s的施加速率，由每位实验者交替进行压力阈值读数。每个触发点的测量相隔5分钟完成。组内相关系数（ICC）显示，TP2的第一次（ICC = 0.82）和第二次试验（ICC = 0.90）以及TP3的第一次（ICC = 0.86）和第二次试验（ICC = 0.92）的评分者间信度都很高。TP3的评分者内信度（ICC = 0.91）高于TP2（ICC1 = 0.80；ICC2 = 0.83）。这些结果表明，压力阈值计在测量实验者之间和实验者内部的触发点敏感性方面具有高度可靠性，可能有助于肌筋膜疼痛综合征的诊断和治疗监测。
