Perceiving the size, shape, position and movement of our limbs is essential to help us interact adequately with our environment. An extensive literature shows that chronic pain conditions are often accompanied by various distortions in body perception, which can include changes in perception of the size, shape and temperature of the painful limb11,17,18,22,36. In addition, alterations of the sense of limb position (assessed with the limb in a static posture) have also been observed1,11,33. For example, individuals with Complex Regional Pain Syndrome (CRPS) were shown to overestimate the angular position of their painful wrist on active and passive movements but passive movement elicited the greatest disparity1.
