The study investigated the differences in pain perception in highly (Highs) and low (Lows) hypnotizable patients with chronic benign pain undergoing hypnotic suggestions of analgesia. Self reports of pain intensity were collected in different groups of fibromyalgic patients: (1) Highs and Lows during pre-hypnosis, neutral hypnosis, suggestions for analgesia, posthypnotic conditions; (2) Lows during suggestions for analgesia administered after a mental stress instead of neutral hypnosis; (3) healthy Lows receiving nociceptive stimulation during hypnotic relaxation and suggestions of analgesia. The results showed that Highs and Lows differed in their response to suggestions, but significant analgesia was reported also by Lows. These individuals did not report any difference in pain perception between the sessions including mental stress and hypnotic relaxation. No change in pain perception was observed in healthy Lows during nociceptive stimulation associated with relaxation and suggestions for analgesia. In conclusion, the presence of chronic pain seems to be responsible for the paradoxical response of non hypnotizable patients to hypnotic suggestions.
该研究调查了在接受镇痛催眠暗示的慢性良性疼痛的高（Highs）催眠性和低（Lows）催眠性患者中疼痛感知的差异。在不同组的纤维肌痛患者中收集疼痛强度的自我报告：（1）高催眠性和低催眠性患者在催眠前、中性催眠、镇痛暗示、催眠后状态下；（2）低催眠性患者在精神应激后而非中性催眠下接受镇痛暗示时；（3）健康的低催眠性患者在催眠放松和镇痛暗示期间接受伤害性刺激时。结果表明，高催眠性和低催眠性患者对暗示的反应不同，但低催眠性患者也报告了显著的镇痛效果。这些个体在包括精神应激和催眠放松的各阶段之间未报告疼痛感知有任何差异。在与放松和镇痛暗示相关的伤害性刺激期间，健康的低催眠性患者未观察到疼痛感知的变化。总之，慢性疼痛的存在似乎是导致非催眠性患者对催眠暗示产生矛盾反应的原因。
