What is an Ergonomic Computer Keyboard?
In today’s world, using a computer keyboard is a part of everyday life for many. Computers form the center of most office workspaces, and many homes have at least one computer. For those away from work or home, laptop computers make it easy for people to bring a computer with them while on the go. The increased use of computer keyboards has led to an increase in repetitive stress injuries of the wrist, hand, and/or arm, such as carpal tunnel syndrome. While seemingly innocuous, the constant and repetitive motion of typing on a computer keyboard day after day can cause a tremendous amount of stress on the body and over time can lead to injury. An ergonomic computer keyboard is designed to work with the natural design of the human wrist, hand and arm to reduce the likelihood of an injury due to repetitive stress. The United States Centers for Disease Control (CDC), defines ergonomics as “a discipline that involves arranging the environment to fit the person in it. When ergonomics is appl
Computer keyboard manufacturers have started promoting certain keyboards as “ergonomic.” Although some of this is advertising hype, a number of innovative keyboard designs have been developed. Most serious efforts at redesigning keyboards have centered on minimizing wrist motions and awkward wrist postures. Such designs may reduce risk factors such as wrist deviation. Some of these keyboards have documented improvements in productivity (e.g.. typing rates), but little research has been conducted to demonstrate that “ergonomic” keyboards actually prevent injuries. Moreover, it is critical to remember that issues of work organization can significantly affect the amount of time spent keying, which may be the most important factor. Back to top.
