Abstract

  Pain is a subjective sensation that is difficult to measure and/or assess. Methods of pain intensity measurement that have been presented in the past, including the visual analogue scale (VAS) , are all subjective. A device for quantitative analysis of perception and pain sensation has now been devised which quantitatively assesses a patient's pain by replacing it with another sensation that does not accompany pain. This device will enable a more objective measurement of pain intensity as well as a comparison and evaluation of pain intensities among different patients or that of a patient over a long period of time. Presented is a part of our clinical data in comparison with VAS.
