The psychophysical attributes of pain that relate to pathophysiological pain have been characterized using several measurement methods, including direct scaling methods. These include thresholds for pain, adaptation, noxious stimulus intensity-pain intensity relationships, discri-minability, and temporal and spatial summation of suprathreshold pain. Here we focus on a few tests that we consider to be simple and yet the most useful in characterizing hyperalgesia and allodynia in pain patients, including neuropathic pain, fibromyalgia, and IBS patients. Responses to these tests have been useful in characterizing the variability in severity of these pain conditions and their central pathophysiological mechanisms.
