Abstract
Disclosed is a pain measurement system and method that make possible the quantitative measurement of human clinical pain. The perception of the pain generated by the subject's source of preexisting pain is compared with a pseudo pain feeling which is produced by a gradual change in an electric stimulus generated by the system. This device measures the point at which the subject's perception of actual pain approximates the intensity of the pseudo pain feeling generated by the system. In this way the magnitude of the source of pain [x] is estimated quantitatively. The minimum perception level of a subject is also determined and a ratio of current level for actual pain to current level for minimum perception level is taken to quantify the pain.
