Computer Use Can Harm Your Health
A digital malady called “iPad shoulder” joins computer vision syndrome, BlackBerry thumb and E-thrombosis on the list of odd—and often painful—disorders afflicting our increasingly wired society.
In a new study, researchers at Harvard’s School of Public Health report that the millions of Americans who use tablet computers, such as the iPad, risk shoulder and neck injuries because of the way they hold the high-tech devices. In the study, 15 experienced users performed a range of simulated tasks on an iPad 2 and Motorala Xoom while their postures were analyzed with a 3-D motion analysis system.
While using the tablets, the volunteers bent their necks more, compared to using a desktop or laptop device, especially when the tablet was in their lap. That hunched posture strains the neck and shoulders, the researchers say. They advise tablet devotees to change positions every 15 minutes, move their neck around to release tension, and to use a case to prop the iPad at the preferred angle of 30 degrees.
