Interventions
The study involves a surgical implant of cuff electrodes on the nerves in the amputated limb, and muscle recording electrodes the remaining muscles. These will be connected to an implanted stimulator. The stimulator will connect wirelessly to an advanced prosthesis. This may allow a user to move the prosthetic hand intuitively and feel what your prosthesis is touching.
