1. A method of using diagnostic apparatus for measuring the relationship between distress level and physiological force due to pain developed by a live being, that comprises the steps ofproviding a force plate system comprising at least one force plate to receive said physiological forces supporting at least some portion of a live being on said at least one force plate operable to produce an analog output signal comprising a dc component and an ac component;

  • providing analyzer means connected to said analog output signal distinguishing between the dc component and the ac component thereby to produce an output signal derived from the ac component that quantifies said distress level;

    including the further step of preparing from the output signal a force amplitude hisogram over a predetermined time interval having a width indicating the level of distress due to pain.
