A multi‑dimensional framework for prosthetic embodiment: a perspective for translational research

Prosthetic embodiment is a complex phenomenon capturing how strongly a prosthesis is perceived to be part of our own body (ownership) and to what degree we are in control of the prosthesis (agency). We proposed a multi-dimensional framework to showcase that prosthetic embodiment depends heavily on which tasks a prosthesis is used for (degree of interaction with the environment) and which prosthetic technology is used to do so (more advanced prostheses offer more functionality and thus the basis for volition and multisensory input to be correctly integrated more frequently). This work provides the context required to better understand prosthetic embodiment research and thereby make its results more relevant and readily applicable to prosthetics outside the research laboratories.
