Persistent chronic pain leads to cortical changes in areas involved in the recognition of emotions. Wand et al. suggest a close correlation between the affective pain component and the extent to which these changes occur. As a consequence, the emotion profile may be influenced and difficulties in emotional communication may arise.
A total of 49 patients with chronic low back pain (CLBP) were classified as grade 1 + 2 or 3 + 4 using the Graded Chronic Pain Scale (GCPS) questionnaire. In all patients, the ability to recognize basic emotions coded through facial expression was assessed using the Facially Expressed Emotion Labeling (FEEL) test. Furthermore, the Toronto Alexithymia Scale-26 (TAS-26) was used to assess if the patients showed signs of alexithymia. Data of the GCPS grade 3 + 4 (n = 35) group were analyzed.
Findings of the FEEL test indicate that the GCPS grade 3 + 4 group recognized the basic emotion 'surprise' significantly more often (p = 0.001) and showed a higher level of currently perceived anger than unaffected subjects. The TAS-26 showed that 28.5 % of the patients with CLBP were alexithym.
The results suggest changes in the recognition of emotions and that patients with CLBP show signs of alexithymia. Further studies with larger sample sizes are required to confirm the detected trends.
持续性慢性疼痛会导致参与情绪识别的脑区发生皮质变化。万德等人指出情感性疼痛成分与这些变化发生的程度之间存在密切关联。因此，情绪特征可能会受到影响，进而可能出现情绪交流困难的情况。
使用分级慢性疼痛量表（GCPS）问卷将49例慢性下腰痛（CLBP）患者分为1 + 2级或3 + 4级。对所有患者，使用面部表情情绪识别（FEEL）测试评估其识别通过面部表情编码的基本情绪的能力。此外，使用多伦多述情障碍量表-26（TAS-26）评估患者是否表现出述情障碍的迹象。对GCPS 3 + 4级（n = 35）组的数据进行分析。
FEEL测试结果表明，GCPS 3 + 4级组识别基本情绪“惊讶”的频率显著更高（p = 0.001），且与未受影响的受试者相比，当前感知到的愤怒水平更高。TAS-26显示，28.5%的CLBP患者存在述情障碍。
结果表明情绪识别存在变化，且CLBP患者表现出述情障碍的迹象。需要进一步开展更大样本量的研究以证实所检测到的趋势。
