Using Complex Biomechanics Models to Communicate Simple Messages

Most people understand that lifting with the knees bent is better than lifting from the waist, but they have trouble comprehending how much better it is, or why. Using biomechanical analysis tools to provide objective proof that one specific method is better than another can help people understand the how and why. Unfortunately, biomechanical models output very complex information. Therefore, a way to succinctly express the difference between the two methods is needed. This presentation reviews the use of data from biomechanical analyses to help workers to choose biomechanically advantageous work methods, and suggests how to present these concepts effectively.
