Here we describe the results of non-painful stimulation in cortical and subcortical lateralization and reorganization and also examine the involvement of subcortical structures in phantom limb telescoping perception.
What is neuroplasticity and what does phantom limb syndrome tell us about it?
In the 1990s researchers found that neuroplasticity—the ability of neurons in the brain to modify their connections and behaviour—could explain pain phenomena that had been observed in association with phantom limb syndrome.
What is mirror therapy for phantom limb pain?
Mirror therapy is a type of therapy that uses vision to treat the pain that people with amputated limbs sometimes feel in their missing limbs.
