Ergonomics.

Ergonomics is the application of natural laws governing human work in order to maximize safety and efficiency in the workplace. Ergonomic assessment includes job analysis from the biomechanical, physiologic, and physical viewpoints. The three most commonly described categories of ergonomic intervention are worker training, worker selection, and job redesign. In the last analysis, workplace redesign, using both engineering and administrative methods, is likely to be the most effective intervention.
