If phantom limb pain is a referred pain syndrome similar to sciatica, specific changes in physiology such as blood flow, nerve conduction, and muscle tension that influence neural activity in the periphery ought to affect phantom pain. On the other hand, if the impulses responsible for phantom pain originate exclusively in the CNS, such correlates might not be found or might be only very indirectly associated with changes in the pain.
