Table 2

Proposed theoretical mechanisms to explain phantom limb pain.

(1) Pheripheral mechanism
 Stump and neuroma hyperactivity

(2) Central neural mechanisms
 Spinal cord sensitization and changes
 Cortical reorganization and cortical-motor sensory dissociation
 Body schema, neuromatrix and neurosignature hypothesis

(3) Psychogenic mechanism
