OBJECTIVE
To investigate the intra- and inter-rater reliability of three measurements on painful and pain-free sides in participants with chronic low back pain (CLBP) at different ages.
METHODS
We recruited 60 participants with CLBP and divided them equally into a group of younger participants with chronic low back pain (18 ≤ age ≤ 35, Y-CLBP) and a group of older participants with chronic low back pain (36 ≤ age ≤ 65, O-CLBP). Participants were assessed by two testers within the same day (10 min interval), and one of the testers repeated the assessment program 24 h later. The intraclass correlation coefficient (ICC) was used to assess reliability. The Pearson correlation coefficient was used to analyze the correlation between tactile acuity and age, waistline, and pain-related variables.
RESULTS
In the Y-CLBP group, the intra-rater reliability of two-point discrimination (TPD), point-to-point test (PTP), and two-point estimation (TPE) on the painful and pain-free sides was good (ICC range: 0.74-0.85), whereas the inter-rater reliability of TPD, PTP, and TPE on the painful and pain-free sides was moderate to good (ICC range: 0.65-0.76). In the O-CLBP group, the intra-rater reliability of TPD, PTP, and TPE on the painful and pain-free sides was good (ICC range: 0.75-0.85), whereas the inter-rater reliability of TPD, PTP, and TPE on the painful and pain-free sides was moderate to good (ICC range: 0.70-0.85). Age, waistline, duration of pain, maximum pain, general pain, and unpleasant score caused by pain were positively correlated with tactile acuity thresholds (D-TPD, A-TPD, PTP, and TPE) ( > 0.365, < 0.05). When BMI was controlled, age, waistline, and pain-related variables were positively correlated with tactile acuity thresholds (r > 0.388; < 0.05).
CONCLUSION
In the participants of Y-CLBP and O-CLBP groups, TPD, PTP, and TPE have moderate-to-good intra- and inter-rater reliability on the painful and pain-free sides of the fifth lumbar vertebrae.
目的
研究不同年龄慢性下腰痛（CLBP）患者疼痛侧与非疼痛侧三项测量指标的评分者内信度和评分者间信度。
方法
招募60例CLBP患者，将其平均分为年轻慢性下腰痛组（18≤年龄≤35岁，Y-CLBP）和老年慢性下腰痛组（36≤年龄≤65岁，O-CLBP）。在同一天内由两名测试者对参与者进行评估（间隔10分钟），其中一名测试者在24小时后重复评估程序。使用组内相关系数（ICC）评估信度。采用Pearson相关系数分析触觉敏锐度与年龄、腰围及疼痛相关变量之间的相关性。
结果
在Y-CLBP组中，疼痛侧与非疼痛侧两点辨别（TPD）、点对点测试（PTP）和两点估计（TPE）的评分者内信度良好（ICC范围：0.74 - 0.85），而疼痛侧与非疼痛侧TPD、PTP和TPE的评分者间信度为中等至良好（ICC范围：0.65 - 0.76）。在O-CLBP组中，疼痛侧与非疼痛侧TPD、PTP和TPE的评分者内信度良好（ICC范围：0.75 - 0.85），而疼痛侧与非疼痛侧TPD、PTP和TPE的评分者间信度为中等至良好（ICC范围：0.70 - 0.85）。年龄、腰围、疼痛持续时间、最大疼痛程度、总体疼痛程度以及疼痛引起的不适感评分与触觉敏锐度阈值（D-TPD、A-TPD、PTP和TPE）呈正相关（>0.365，<0.05）。在控制体重指数后，年龄、腰围和疼痛相关变量与触觉敏锐度阈值呈正相关（r>0.388；<0.05）。
结论
在Y-CLBP组和O-CLBP组参与者中，第五腰椎疼痛侧与非疼痛侧的TPD、PTP和TPE具有中等至良好的评分者内信度和评分者间信度。
