Abstract: Prosthetic liner apparatus for improving suspension and rotation control between a residual limb and a socket of a prosthesis include a liner body having a shape configured to receive the residual limb and having an outer surface that fits within the socket. The liner body may have a plurality of raised elastomeric grips located on its outer surface and a proximal end of the outer surface of the liner body includes at least an exposed smooth elastomeric region that fits within and seals with the socket. Further disclosed is a prosthetic sock having raised elastomeric grips on its inner and outer surfaces which is for use with a liner body that is smooth or textured and that may or may not include raised elastomeric grips, and that when used together with the liner body ay form a liner apparatus.

Abstract: A system to perform neurorehabilitation includes a display that is visible to a user. The system also includes a camera operatively coupled to the display and configured to capture a walking surface upon which the user is walking. The system further includes a processor operatively coupled to the display and to the camera. The processor is configured to project a virtual object onto the walking surface such that the virtual object is visible to the user on the display. The processor is also configured to monitor user movement relative to the virtual object.
