Phantom Limb Pain
Phantom limb pain (PLP) is a complex phenomenon that includes a wide variety of symptoms ranging from tingling and itching to burning and aching. During the past twenty years researchers have advanced a number of theories to explain phantom limb pain. Three of the most prominent are: 1) maladaptive changes in the primary sensory cortex after amputation (maladaptive plasticity), 2) a conflict between the signals received from the amputated limb (proprioception) and the information provided by vision that serves to send motor commands to the missing limb, 3) vivid limb position memories that emerge after amputation.

Famous quotes containing the words phantom, limb and/or pain:
“It was a favor for which to be forever silent to be shown this vision. The earth beneath had become such a flitting thing of lights and shadows as the clouds had been before. It was not merely veiled to me, but it had passed away like the phantom of a shadow, skias onar, and this new platform was gained. As I had climbed above storm and cloud, so by successive days’ journeys I might reach the region of eternal day, beyond the tapering shadow of the earth.”
—Henry David Thoreau (1817–1862)
“should some limb of the devil
Destroy the view by cutting down an ash
That shades the road, or setting up a cottage
Planned in a government office, shorten his life,
Manacle his soul upon the Red Sea bottom.”
—William Butler Yeats (1865–1939)
“The human condition is such that pain and effort are not just symptoms which can be removed without changing life itself; they are the modes in which life itself, together with the necessity to which it is bound, makes itself felt. For mortals, the “easy life of the gods” would be a lifeless life.”
—Hannah Arendt (1906–1975)
