我们对身体或身体意象的意识通常被认为是理所当然的，但它在许多临床状态中被破坏，包括复杂的疼痛综合征和幻肢痛。慢性背痛也是如此吗？通过参与者的绘画，对6名慢性背痛患者和10名健康对照者的身体形象进行了评估。详细评估触觉阈值和两点辨别阈值（TPD）。所有的患者，没有一个对照组，显示出背部的身体形象被破坏。5名患者无法清楚描绘躯干轮廓，并表示他们无法“找到”。在体像缺失或破坏的同一区域，TPD大大增加，但在其他方面与对照组相似。尽管没有异常性疼痛，并且静息痛水平与TPD之间没有关系，但体像障碍和触觉敏锐度下降符合疼痛的正态分布。患者和对照组的触觉阈值无显著差异。这些初步数据表明，在慢性背痛患者的常见疼痛区域，身体形象被破坏，触觉敏锐度降低。这一发现提出了一种可能性，即训练身体意象或触觉敏锐度可能有助于慢性脊柱疼痛患者，就像它在幻肢痛的复杂区域疼痛综合征患者中所做的那样。(C)2008年国际疼痛研究协会。Elsevier B.V.出版，保留所有权利。
The conscious sense of our body, or body image, is often taken for granted, but it is disrupted in many clinical states including complex regimal pain syndrome and phantom limb pain. Is the same true for chronic back pain? Body image was assessed, via participant drawings, in six patients with chronic back pain and ten healthy controls. Tactile threshold and two-point discrimination threshold (TPD) were assessed in detail. All the patients, and none of the controls, showed disrupted body image of the back. Five patients were unable to clearly delineate the outline of their trunk and stated that they could not "find it". TPD was greatly increased in the same zone as the absense or disruption of body image, but was otherwise similar to controls. The disturbance of body image and decrease in tactile acuity coincided with the normal distribution of pain, although there was no allodynia and there was no relationship between resting pain level and TPD. Tactile threshold was unremarkable for patients and controls. These preliminary data indicate that body image is disrupted, and tactile acuity is decreased, in the area of usual pain, in patients with chronic back pain. This finding raises the possibility that training body image or tactile acuity may help patients in chronic spinal pain, as it has been shown to do in patients with complex regional pain syndrome of phantom limb pain.
