Abstract
Phantom limb pain (PLP) is not only a physical pain experience but also poses a significant challenge to mental health and quality of life. Currently, the mechanism of PLP treatment is still unclear, and there are many methods with varying effects. This article starts with the application research of extended reality technology in PLP treatment, through describing the application of its branch technologies (virtual reality, augmented reality, and mixed reality technology), to lay the foundation for subsequent research, in the hope of finding advanced and effective treatment methods, and providing a basis for future product transformation.
