A Cornell university researcher is looking for ways to reduce IT-related repetitive motion injuries. Alan Hedge is evaluating a vibrating mouse, as well as an LCD monitor on an adjustable arm to determine whether these devices can reduce computer-related injuries to office workers.

So far, Hedge's observations are mixed. The vibrating mouse does remind users to remove their hands from the device when they're not using it, however, test subjects tended to hover directly over the mouse using a hand position that could create injuries that are just as serious or perhaps worse than those created by holding onto a mouse.

The LCD monitor mounted to an adjustable arm, however shows promise. Users reported a reduction in neck and back pain when using the mounted monitors.
