Phantom Limb Pain Treatment Based on Augmented Reality and Gaming

Many treatments have been used to alleviate phantom limb pain (PLP) with varying success. Researchers at Sweden's Chalmers University of Technology and Sahlgrenska University Hospital have developed a treatment in which the virtual limb responds directly to myoelectric activity at the stump, while the illusion of a restored limb is enhanced through augmented reality (AR). Further, phantom motions are facilitated and encouraged through gaming. This successful case study of a chronic PLP patient demonstrates the new treatment. The study, led by biomedical engineer Max Ortiz-Catalan, was published in Frontiers in Neuroscience.
