Computer stations get failing grade

Millions of youths may be at risk for musculoskeletal injury because computer workstations in schools are not designed for growing children, according to a New York study.

Investigators observed 95 third-through fifth-graders typing on school computers in 18 different settings. Using the Rapid Upper Limb Assessment (RULA), observers evaluated the postures of the upper and lower arm, wrist, neck, trunk and legs. They also measured the height of the keyboard, monitor, seat and chair back; seat width; chair back and seat angle; and whether the workstation was adjustable.

Investigators found all keyboards and most monitors were higher than recommended levels; none of the workstations was adjustable; and none of the keyboards had wrist or palm rests. Chair dimensions were closer to the standards, although some seat backs were too high.
