1. Innocuous (mechanoreception) and noxious (nociception) prosthesis sensing and discrimination in an amputee.
Innocuous (mechanoreception) and noxious (nociception) prosthesis sensing and discrimination in an amputee. (A) The amputee could discriminate which region of his phantom hand was activated, if at all. (B) Perception of pain increases with decreasing radius of curvature (i.e., increase in sharpness) for the objects presented to the prosthetic hand. (C) Discrimination accuracy shows the participant’s ability to reliably identify each object presented to the prosthesis based purely on the sensory feedback from the neuromorphic stimulation. (D) Results from the PDT during user-controlled movements, with pain reflex enabled.
