Abstract

Introduction: Patients with chronic pain and high-level catastrophic thoughts often do not respond to acupuncture. This may be related to hypofunctioning of the dorsolateral prefrontal cortex and the descending pain inhibitory system. Therefore, we examined the relationship between the level of catastrophic thinking and the analgesic effect of electroacupuncture using the pain catastrophizing scale (PCS). We also evaluated the descending pain inhibitory system using conditioned pain modulation (CPM) and offset analgesia (OA). The relationship between catastrophic thinking and the descending pain inhibitory system was also examined.

Materials and methods: After testing the hospital anxiety and depression scale and the PCS in 14 healthy adults, the current pain threshold (CPT), CPM, and OA were measured, in order, before the intervention. Thereafter, electroacupuncture was applied to 3 limbs (the dominant hand and both lower extremities) at 4 Hz, and to the scalp at 100 Hz, for 30 minutes, and the CPT was measured again immediately after the intervention. The difference in the CPT before and after the intervention was taken as the analgesic effect.

Results: The participants were divided into 2 groups, the H-PCS group (≥16 points) and the L-PCS group (≤15 points), according to the PCS score, and the analgesic effects of electroacupuncture were significantly different (P = 0.04). However, no relationship was found between the PCS score and the CPM (r = -0.02, P = 0.94) and OA effects (r = -0.19, P = 0.49).

Conclusion: It was suggested that people with high-level catastrophic thinking may find it difficult to obtain the analgesic effects of electroacupuncture.

灾难性思维对电针镇痛效果的影响
简介患有慢性疼痛和高度灾难性思想的患者往往对针灸没有反应。这可能与背外侧前额叶皮层和下行疼痛抑制系统功能低下有关。因此,我们使用疼痛灾难化量表(PCS)研究了灾难性思维水平与电针镇痛效果之间的关系。我们还使用条件性疼痛调节(CPM)和偏移镇痛(OA)评估了降序疼痛抑制系统。我们还研究了灾难性思维与降痛抑制系统之间的关系:在对 14 名健康成年人进行医院焦虑抑郁量表和 PCS 测试后,在干预前依次测量了当前疼痛阈值(CPT)、CPM 和 OA。然后,以 4 赫兹的频率对 3 个肢体(惯用手和双下肢)进行电针,以 100 赫兹的频率对头皮进行电针,持续 30 分钟,并在干预后立即再次测量 CPT。干预前后的 CPT 差值即为镇痛效果:结果:根据 PCS 评分将受试者分为两组,即 H-PCS 组(≥16 分)和 L-PCS 组(≤15 分),电针镇痛效果有显著差异(P = 0.04)。然而,PCS评分与CPM(r = -0.02,P = 0.94)和OA效果(r = -0.19,P = 0.49)之间没有关系:结论:有高度灾难性思维的人可能难以获得电针的镇痛效果。
