本研究的主要目的是研究年龄对热痛阈和反应时的影响，并分析反应时的年龄相关变化对热痛阈和热痛阈的影响。用极限法评价热阈值（温/冷）和热痛阈值（热/冷）。视觉反应时间通过定制的计算机程序以类似的方式进行评估。共招募了274名正常受试者（23-87岁）。热阈值、热痛阈值和反应时间均与年龄有关。热痛阈随年龄增长而降低，冷痛阈、热痛阈随年龄增长而升高。反应时间的年龄相关变化不足以解释热痛阈和热痛阈的年龄相关变化。总之，年龄影响热和热痛阈值独立的反应时间。(C)2009爱思唯尔有限公司版权所有。
The main goals of this study were to investigate the effect of age on thermal and thermal pain thresholds and reaction time, and to analyze the influence of age-related changes in reaction time on thermal and thermal pain thresholds. Thermal thresholds (warm/cold) and thermal pain thresholds (hot/cold) were evaluated by the method of limits. Visual reaction time was evaluated in a similar way by a customized computer program. In total, 274 normal subjects (23-87 years old) were recruited. Thermal thresholds, thermal pain thresholds, and reaction time were all related to age. While warm and cold thresholds and cold pain thresholds increased with age, hot pain thresholds decreased with age. The age-related change in reaction time was insufficient to explain the age-related changes in thermal and thermal pain thresholds. In conclusion, age affects thermal and thermal pain thresholds independently of reaction time. (C) 2009 Elsevier Ltd. All rights reserved.
