背景下行疼痛调节系统控制脊髓水平伤害性信息的传递，并且它们的活动可以通过认知和情绪过程来改变。因此，有可能学习使用认知情感策略来专门针对下行通路，以实现减轻疼痛。 方法本研究使用伤害性屈肌反射（RIII反射）的视觉反馈来训练健康受试者经过三个疗程，通过自我选择的认知情感策略来减少他们的脊柱伤害性感受（RIII反射大小）。该研究包括两个反馈组（固定刺激间隔与随机刺激间隔）和一个没有反馈的对照组（每组 15 名受试者）。结果虽然所有三组都成功降低了 RIII 反射（p
BackgroundDescending pain modulatory systems control transmission of nociceptive information at the spinal level, and their activity can be modified by cognitive and emotional processes. Thus, it may be possible to learn using cognitive-emotional strategies to specifically target descending pathways in order to achieve pain reduction.MethodsThe present study used visual feedback of the nociceptive flexor reflex (RIII reflex) to train healthy subjects over three sessions to reduce their spinal nociception (RIII reflex size) by self-selected cognitive-emotional strategies. The study included two feedback groups (fixed vs. random stimulation intervals) and a control group without feedback (15 subjects each).ResultsWhile all three groups successfully reduced their RIII reflexes (p
