在10和100赫兹下测量热痛对绝对阈值、感觉幅度和幅度差阈值的影响。与之前的结果一致，与非疼痛状态相比，热诱导疼痛将绝对阈值提高了约8.0db，并降低了疼痛期间的触觉感觉。与这些效应相反，振动触觉刺激强度变化的辨别性不受疼痛的存在的影响，这表明疼痛对触觉感觉的影响更有可能是由于感觉过程而不是认知过程(即注意力)，并且与区分能力相比，触觉敏感性的潜在机制是不同的。
The effects of heat-induced pain on absolute thresholds, sensation magnitudes and amplitude-difference thresholds were measured at 10 and 100 Hz. Consistent with previous results, heat-induced pain elevated the absolute thresholds by approximately 8.0 dB and lessened the magnitudes of tactile sensations during pain as compared to the non-painful condition. In contrast to these effects, the discriminability of change in the intensity of the vibrotactile stimuli was unaffected by the presence of pain indicating that the effect of pain on tactile sensations is more likely due to sensory rather than cognitive processes (i.e., attention) and that the mechanisms underlying tactile sensitivity as compared to discriminability are different.
