目的：为探讨不同部位和局部皮肤温度对热阈的影响，对46名正常志愿者在鱼际隆起（TE）、手背（DH）、腕掌面（VW）和足背（DF）等部位的冷热觉和冷热痛阈进行了比较。TE比DH和VW对温热更敏感，但差异在临床上可忽略不计。DH和VW对温暖同样敏感。TE、DH和VW对冷却同样敏感。个体间方差在TE处最小。温阈值和冷阈值与局部皮肤温度无关（范围为27-37摄氏度）。TE是不太敏感的冷痛，但否则的手和脚同样敏感的热pain.Conclusion：正常受试者的热阈值测试可以充分进行在几个网站在手中，但是，TE是首选的小个体间变异。考虑到TE的阈值较高，TE可优选用于评估冷痛觉过敏。在常规临床评价中通常遇到的范围内，无需加热或冷却皮肤。(C)2000爱思唯尔科学爱尔兰有限公司版权所有。
Objective: To determine the effect of different sites and local skin temperature on thermal thresholds.Methods: Cool and warm detection and cold and heat pain thresholds were compared in 46 normal volunteers at the thenar eminence (TE), dorsum of the hand (DH), volar surface of the wrist (VW) and dorsum of the foot (DF).Results: The hand is more sensitive than the foot for cool and warm. TE is more sensitive for warm than DH and VW but the difference is clinically negligible. DH and VW are equally sensitive to warm. TE, DH, and VW are equally sensitive to cool. inter-individual variance is smallest at TE. Warm and cool thresholds are independent of local skin temperature (range of 27-37 degrees C). TE is less sensitive for cold pain but otherwise the hand and the foot are equally sensitive to thermal pain.Conclusion: Testing of thermal thresholds in normal subjects can be adequately conducted at several sites at the hand, however, TE is preferred given the small inter-individual variability. TE may be preferred for evaluating hyperalgesia to cold given its higher threshold. Warming or cooling of the skin is unnecessary within the range normally encountered in routine clinical evaluation.
