Ergonomics is an applied science focused upon designing and arranging objects people use so they interact most efficiently and safely. Ergonomic techniques and products—and even the ideas that inspired them—used in other fields, by NASA, NASCAR, etc., are showing more prominence in the regular office workplace.

What doesn’t get done on a computer these days? The more time we spend clicking and dragging a regular mouse, the more strain we inflict on our hands and wrists. For those who spend long hours at the office, developing “mouse arm,” or the tech world equivalent of tennis elbow, is a risk.

Few people start out using a computer with an ergonomic mouse. Wrist pain is a frequent consequence. Though it sometimes sounds trivial wrist pain can be excruciating, and can be worsened if your job requires use of a computer for most of the day. Ergonomic mice can help alleviate existing wrist, hand, and arm pain by correcting improper mousing techniques.
