Ergonomic Principles - The Big Three

Ergonomic analysis requires consideration of three (3) main risk factors: Force; Repetition; & Posture. Each of these factors alone poses a risk of injury. However, it is the "Critical Combo" between all three (3) factors that poses the greatest risk of injury. Optimizing your working posture, controlling the frequency (repetition) rate, and minimizing forces can decrease the risk of injury and enhance your task performance. The next few slides will provide some information on these key ergonomics principles as they relate to office work.
