This international, multi-center, double-blind, randomized, controlled clinical trial aims to evaluate the efficacy of Phantom Motor Execution (PME) and Phantom Motor Imagery (PMI) as treatments of Phantom Limb Pain (PLP). In PME, myoelectric pattern recognition (MPR) is used to predict motor volition and then use the decoded movements to control virtual and augmented reality environments (VR/AR), along with serious gaming (SG). The same device and VR/AR environments are used in PMI with the difference that subjects will imagine rather than execute phantom movements. Electromyography is used to monitor for no muscular activity in PMI.
