One aspect of the changes that occur when pain persists is that the proprioceptive representation of the painful body part in primary sensory cortex changes.[45–47] This may have implications for motor control because these representations are the maps that the brain uses to plan and execute movement.[48] If the map of a body part becomes inaccurate, then motor control may be compromised – it is known that experimental disruption of cortical proprioceptive maps disrupts motor planning.[49] The notion of distorted proprioceptive representation has been discussed with regard to its impact on motor control[50,51] and, more recently, in a theoretical way with regard to pain.[52] Although exceptions exist,[53] there is mounting evidence that changes in cortical representation occur in association with chronic pain, and it is feasible that these changes may become part of the problem.[46]
