Virtual reality reduces phantom pain in paraplegics

Virtual reality reduces phantom body pain in paraplegics and creates the illusion that they can feel their paralyzed legs being touched again. The results could one day translate into therapies to reduce chronic pain in paraplegics. In breakthrough research led by neuroscientist Olaf Blanke and his team at EPFL, Switzerland, the scientists show that phantom body pain can be reduced in paraplegics by creating a bodily illusion with the help of virtual reality. The results are published in today's printed issue of Neurology . "We managed to provoke an illusion: the illusion that the subject's legs were being lightly tapped, when in fact the subject was actually being tapped on the back, above the spinal cord lesion," explains Blanke, lead author of the study and holder of the Foundation Bertarelli Chair in Cognitive Neuroprosthetics. "When we did this, the subjects also reported that their pain had diminished." Paraplegics suffer from no longer feeling their legs again, but the condition is often accompanied by neuropathic pain due to the spinal cord lesion. The patient feels pain originating from the legs, even though nothing else can be felt below the lesion.
