温度阈值的确定在临床上用于评估周围神经系统的功能。这项研究的目的是评估一种新的、低成本的设备用于确定皮肤温度敏感性的水平方法的可靠性。19名男性受试者参加了这项研究。分别在右侧前臂中部掌侧表面、上臂中部外侧表面和大腿中部前部进行温度阈值测试。热测试采用水平法，初始温度步长为2℃。温度阈值的变异性用第二次测试和第一次测试之间的比率、变异系数(CV)、重复性系数(CR)、组内相关系数(ICC)、两次测试之间的平均差(S1-S2diff)、测量标准误差(SEM)和最小可检测变化(MDC)来表示。在热阈值或冷阈值之间，或在热阈值和冷阈值之间，没有统计上的显著变化。受试者内部的简历是可以接受的。热阈值的CR估计范围为0.74°C至1.06°C，冷阈值的CR估计范围为0.67°C至1.07℃。评分者内信度的ICC值温阈值为0.41~0.72，冷阈值为0.67~0.84。S_1-S_2diff温阈值为−0.15℃~0.07℃，冷阈值为−0.08℃~0.07℃。扫描电子显微镜的温阈值为0.26℃至0.38℃，冷阈值为0.23℃至0.38℃。温暖阈值的MDC估计值在0.60°C到0.88°C之间，冷阈值的MDC值在0.53°C到0.88°C之间。皮肤温度敏感度的水平法具有较好的可靠性。
Determination of the thermal thresholds is used clinically for evaluation of peripheral nervous system function. The aim of this study was to evaluate reliability of the method of levels performed with a new, low cost device for determining cutaneous temperature sensitivity. Nineteen male subjects were included in the study. Thermal thresholds were tested on the right side at the volar surface of mid-forearm, lateral surface of mid-upper arm and front area of mid-thigh. Thermal testing was carried out by the method of levels with an initial temperature step of 2°C. Variability of thermal thresholds was expressed by means of the ratio between the second and the first testing, coefficient of variation (CV), coefficient of repeatability (CR), intraclass correlation coefficient (ICC), mean difference between sessions (S1-S2diff), standard error of measurement (SEM) and minimally detectable change (MDC). There were no statistically significant changes between sessions for warm or cold thresholds, or between warm and cold thresholds. Within-subject CVs were acceptable. The CR estimates for warm thresholds ranged from 0.74°C to 1.06°C and from 0.67°C to 1.07°C for cold thresholds. The ICC values for intra-rater reliability ranged from 0.41 to 0.72 for warm thresholds and from 0.67 to 0.84 for cold thresholds. S1-S2diff ranged from −0.15°C to 0.07°C for warm thresholds, and from −0.08°C to 0.07°C for cold thresholds. SEM ranged from 0.26°C to 0.38°C for warm thresholds, and from 0.23°C to 0.38°C for cold thresholds. Estimated MDC values were between 0.60°C and 0.88°C for warm thresholds, and 0.53°C and 0.88°C for cold thresholds. The method of levels for determining cutaneous temperature sensitivity has acceptable reliability.
