Abstract: Proprioception is the body’s sense of limb position and movement and is a vital part of motor planning. When an amputation occurs, proprioception in the missing limb is lost and previously simple motor tasks can become much more difficult. Because of this, proprioceptive feedback is highly desired by prosthesis users. In this talk, I present data which characterizes proprioceptive percepts in a patient with trans-radial limb loss. I compare it to another participant who did not experience proprioceptive sensation in his phantom hand. Then, I develop a model of how electrical stimulation interacts with the sensory systems responsible for proprioception to explain the differences between the two patients. I provide background supporting this model and finally, I expand on future experiments to test it.
