Pain is in the eyes of the beholder
Date:11/25/2008

By manipulating the appearance of a chronically achy hand, researchers have found they could increase or decrease the pain and swelling in patients moving their symptomatic limbs. The findingsreported in the November 25th issue of Current Biology, a Cell Press publicationreveal a profound top-down effect of body image on body tissues, according to the researchers.

"The brain is capable of many wonderful things based on its perception of how the body is doing and the risks to which the body seems to be exposed," said G. Lorimer Moseley, who is now at the Prince of Wales Medical Research Institute in Australia. (The work was done at the University of Oxford.)

In the study, the researchers asked ten right-handed patients with chronic pain and dysfunction in one arm to watch their own arm while they performed a standardized set of ten hand movements. The participants repeated the movements under four conditions: with no visual manipulation, while looking through binoculars with no magnification, while looking through binoculars that doubled the apparent size of their arm, and while looking through inverted binoculars that reduced the apparent size of their arm.

While the patients' pain was always worse after movement than it was before, the extent to which the pain worsened depended on what people saw. Specifically, the pain increased more when participants viewed a magnified image of their arm during the movements, andperhaps more surprisinglythe pain became less when their arm was seen through inverted binoculars that minimized its size.

The degree of swelling too was less when people watched a "minified" image of their arm during movements than when they watched a magnified or normal image, the researchers reported.

They aren't yet sure how this phenomenon works at the level of neurons. However, the researchers said, a possible philosophical explanation comes from the notion that protective responsesincluding t
