Eight patients with atopic eczema and six healthy subjects were given hypnotic suggestion to feel pain in the upper part of the back and in one case on the palm. An average local increase in skin temperature of 0.6 degrees C (detected by thermovision) occurred under this condition. For some patients cutaneous pain threshold was increased before the experiment by means of repetitive hypnotic suggestion of analgesia. These subjects reported feeling no pain subjectively, but the local change in skin temperature was equal in both cases. The results suggest a central mechanism induced by measuring changes in pain threshold in the skin, which changes are independent of local changes in blood flow.
八名特应性皮炎患者和六名健康受试者接受催眠暗示，使其感到背部上方疼痛，有一例是手掌疼痛。在此条件下，通过热成像检测到皮肤温度平均局部升高0.6摄氏度。对于一些患者，在实验前通过反复的催眠镇痛暗示提高了皮肤疼痛阈值。这些受试者主观上报告没有疼痛，但两种情况下皮肤温度的局部变化是相同的。结果表明，通过测量皮肤疼痛阈值的变化可诱发一种中枢机制，这种变化与局部血流变化无关。
