What Is Ergonomics?

Ergonomics is the study of the relationship between humans and the objects that we use. The term is derived from two Greek words: ergon, meaning “work,” and nomoi, meaning “natural laws.” Ergonomists study human anatomy in order to determine how the objects that we use can be made safer, more comfortable, and more efficient.

Ergonomists do more than recommend how to sit at a computer. They are becoming increasingly involved in product design. Some ergonomists believe that product manufacturers are too far removed from the users of their products. In other words, these ergonomists believe that when manufacturers plan the design of their products, they often do not take into account the users’ physical limitations or comfort. If you have ever sat on a chair that was uncomfortable or used a vacuum cleaner that required you to stoop constantly, then you have come across a product that perhaps was attractive or worked well, but that did not incorporate ergonomics into its design.

Ergonomists want to help manufacturers use product design that prevents discomfort and injury. Manufacturers of computer-related products have begun to offer a wide array of ergonomically-designed accessories, including ergonomic computer chairs, mice, mouse pads, arm rests, foot rests, keyboards, and writing instruments. The design of all of these ergonomic products attempt to reduce the forces that act upon the body.

Why Use Ergonomics?

Injuries that are related to poorly designed tools or work environments are not only painful, they are costly. According to the Bureau of Labor Statistics, nearly half of all worker-compensation costs each year are due to ergonomic-related injuries. Such injuries can lead to cumulative-trauma disorders, which occur because muscles are repeatedly stressed, nerves are pinched, or blood flow is restricted. The body parts that are most vulnerable to cumulative-trauma are the back, hand, wrist, forearm, and neck. Protecting these body parts will not only help you avoid pain, but it might also help both you and your company avoid costly medical expenses.
