Abstract

Thermal threshold testing is important for evaluating the thermal function of small-fibre nerve types C and A-delta. This study investigated the reliability and validity of a novel nerve testing device (NNTD) in evaluating thermal detection and thermal pain thresholds. Test-retest reliability of the NNTD and its concurrent validity compared to the current technology (Medoc TSA-2, Advanced Thermosensory Stimulator, Israel) were investigated among 10 healthy participants. Each participant was tested for the warm detection threshold (WDT), cold detection threshold (CDT), hot pain threshold (HPT) and cold pain threshold (CPT) on the medial forearm with NNTD for two trials and the Medoc TSA-2 for one trial over two consecutive days. Intraclass Correlation Coefficient values, Standard Error of Measurement and Bland Altman plots were calculated for test-retest reliability. One-way ANOVA and Bland Altman plots were calculated for validity. The test-retest reliability of the NNTD was good for CPT (ICC = 0.88), moderate for WDT (ICC = 0.545) and HPT (ICC = 0.710). The NNTD was valid for both trials of HPT and CPT and one trial for WDT compared to the Medoc TSA-2. In conclusion, the NNTD showed good to moderate reliability and was found to be valid compared to the Medoc TSA-2.

新型热检测和热痛阈值神经测试装置的重测信度和并发效度。

热阈值测试是评价C型和a型δ小纤维神经热功能的重要手段。本研究探讨了一种新型神经测试装置(NNTD)在评估热检测和热痛阈值方面的信度和效度。在10名健康受试者中调查了NNTD的重测信度及其与当前技术(Medoc TSA-2, Advanced Thermosensory Stimulator, Israel)的并发效度。在连续两天的时间内，对每位受试者分别进行两组NNTD前臂内侧的热检测阈值(WDT)、冷检测阈值(CDT)、热痛阈值(HPT)和冷痛阈值(CPT)测试，其中一组为Medoc TSA-2测试。计算类内相关系数值、测量标准误差和Bland Altman图来计算重测信度。采用单因素方差分析和Bland Altman图计算效度。NNTD对CPT的重测信度较好(ICC = 0.88)，对WDT (ICC = 0.545)和HPT (ICC = 0.710)的重测信度中等。与Medoc TSA-2相比，NNTD对HPT和CPT的两项试验都有效，对WDT的一项试验也有效。综上所述，NNTD具有良好到中等的信度，与Medoc TSA-2相比是有效的。
