Hyperalgesia in outpatients with dermal injury: quantitative sensory testing versus a novel simple technique.

Objective: Dermal inflammation from many causes may produce a reversible period of hyperalgesia (increased sensitivity to pain perception) or allodynia (pain from innocuous stimuli). Hyperalgesia and allodynia have received relatively little attention in clinical trials of acute pain. We sought to quantitate tactile allodynia and thermal hyperalgesia in outpatients presenting with acute dermal injuries.
