Repetitive stress injuries can be bad news for business. And the misuse of the computer is a factor. Even when companies go the extra step of providing ergonomic workstations, that doesn’t enforce good work habits among employees. Poor posture and overlong sessions in front of the computer can lead to pain in the wrists, arms, and back. One way to fight back is to take frequent breaks when using the computer. If you can’t rely on your own sense of the clock (or personal discomfort!), there are a host of applications that can help remind you when it’s time to step away from the keyboard. Here are four that received high marks on Download.com (one of our sister sites at CNET).
