How does phantom limb syndrome pain work? Phantom limb pain is pain that is felt in the area where an arm or leg has been amputated. Although the limb is gone, the nerve endings at the site of the amputation continue to send pain signals to the brain that make the brain think the limb is still there.
How does phantom limb pain happen? Experts believe phantom pain results from a mix-up in nervous system signals, specifically between the spinal cord and brain. When a body part is amputated, the nerve connections from the periphery to the brain remain in place.
What happens in the brain during phantom limb pain? A popular theory of the cause of phantom limb pain is faulty ‘wiring’ of the sensorimotor cortex, the part of the brain that is responsible for processing sensory inputs and executing movements. In other words, there is a mismatch between a movement and the perception of that movement.
What mechanism is responsible for phantom limb pain? Sensory experiences create a unique neuromatrix, which is imprinted on the brain. When the limb is removed, the neuromatrix tries to reorganise, but the neurosignature remains due to the chronic pain experienced prior to the amputation. This causes phantom limb pain after amputation.
