Virtual reality could be the answer to treating phantom pain

The team had test subjects wear VR goggles showing live feed from a camera filming a set of dummy legs. Since the camera was positioned to mimic a person’s POV in relation to their legs, the VR provided the illusion that the dummy legs were truly theirs. So, when the scientists simultaneously tapped the dummy legs and the area above the subjects’ spinal lesions caused by their injury, the subjects eventually felt like it was their own legs being tapped. They told the researchers that the sensation diminished the neuropathic pain they felt.

Team leader Olaf Blanke said that “it takes about a minute of simultaneously tapping for the illusion to take place.” He explained that “the tapping on the back gets translated onto the legs because the visual stimulus dominates over the tactile one.” His researchers are now developing what they’re calling an immersive digital therapy that automates visuo-tactile stimulations for spinal injury patients and people suffering from chronic pain conditions.

EPFL didn’t say whether it could also work for amputees and people who have other types of conditions, but this is far from the first time scientists thought of using virtual reality in medicine. There’s a team of researchers from Duke University who developed a VR system that helped paralyzed patients regain some movement. Another team from Europe is exploring the use of VR to fight depression, while a group from Oxford University conducted experiments that used VR to help paranoia patients confront their fears.
