PainSci notes on Moseley 2008:
In this small, unusual study, six patients with low back pain were asked to draw their perceptions of their back and spine. For comparison, a group of ten patients with no recent back pain were asked to do the same exercise. They were encouraged to “draw what it feels like” rather than how it actually looked.
“All the patients, and none of the controls, showed disrupted body image of the back” on the same side and level as the pain. For instance, they did not have a clear sense of the outline of their trunk.
Most intriguingly, patients with back pain on just one side illustrated vertebrae deviated towards the painful side (without any obvious actual deviation).

The conscious sense of our body, or body image, is often taken for granted, but it is disrupted in many clinical states including complex regional 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 absence 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 or phantom limb pain.
