Slouching better than sitting upright
CHICAGO (UPI) -- Research presented in Chicago has suggested that sitting up straight is more stressful on the back than slouching. Dr. Waseem Amir Bashir, who led the study at Woodend Hospital in Aberdeen, Scotland, said at the meeting of the Radiological Society of North America in Chicago sitting with a straight back and thighs parallel to the floor increases the stress on the lower back's lumbar discs, the Chicago Tribune reported Tuesday. "Really the best position is what you get in a La-Z-Boy, although that wouldn't work well for someone using a computer," Bashir said. Bashir and his colleagues based their findings on magnetic resonance imaging data from 22 healthy volunteers who were asked to pose in various sitting positions. They found that leaning forward in a chair, as computer users often to, is even more stressful on the spine than sitting upright. "A 135-degree body-thigh sitting posture was demonstrated to be the best bio-mechanical sitting position, as opposed to a 90-degree posture, which most people consider normal," Bashir said.
