It has been reported to occur in 80-100% of amputees, and typically has a chronic course, often resistant to treatment. That phenomenon occurs because the nerve trunks that connected the now absent limb to the brain still exist and are capable of being excited. "[22], Phantom sensations may also occur after the removal of body parts other than the limbs, e.g. The above-mentioned abnormal sensations have been named, perhaps incorrectly, phantom limb syndrome (PLS), as they are reminiscent of the symptoms reported by amputees who still report sensations in their missing limb. 0.

Most approaches to treatment over the past two decades have not shown consistent symptom improvement. [10], Despite a great deal of research on the underlying neural mechanisms of phantom limb pain there is still no clear consensus as to its cause. [12], Pain, temperature, touch, and pressure information are carried to the central nervous system via the anterolateral system (spinothalamic tracts, spinoreticular tract, spinomesencefalic tract), with pain and temperature information transferred via lateral spinothalamic tracts to the primary sensory cortex, located in the postcentral gyrus in the parietal lobe, where sensory information is represented somatotropically, forming the sensory homunculus.[13].
