Abstract
Focusing on the extension of lower limb sensation, we asked a patient with right lower extremity prosthesis to do a sensation assignment, and examined the sensation condition and analyzed conscious experience from a self-assessment report. The subject was an 81-year-old man who had experienced right below-knee amputation. For four weeks, as a sensation assignment, we asked the subject to distinguish 4 items, material, configuration, hardness and weight on the left sole, right stump, right prosthesis sole, and analyzed the correct answer percentages in the self-assessment report. The highest percentages of correct answers were hardness, material, configuration and weight (weight on left sole and the right prosthesis sole) in this order. In the self-assessment report description, a temporal change was seen, compared to the other items, with a shift from passive to active contact, but a big change was not seen in hardness and weight.
