Visual responsiveness in the somatosensory cortex diminishes significantly following mirror therapy for phantom limb pain. Before therapy, researchers discovered a strong, unexpected activation in the sensorimotor foot region of amputees to visually presented images of the foot. This response was no longer present following mirror therapy.
Researchers present a new theory which states, following amputation, the neural circuitry connected to the missing limb becomes entangled with other neural networks, specifically ones responsible for pain perception.
A new study reports transcranial magnetic stimulation can significantly reduce phantom limb pain.
A new method of treating phantom limb pain which utilizes several technologies is providing successful.
