There are many simple, inexpensive ways to control awkward postures. Change, modify, or redesign the tool. Oftentimes, control measures from all three of these categories are necessary. Let's start with a student writing on a desk, an employee typing on a computer, a parent cooking dinner, and an assembler gluing parts together. While these may seem like very diverse tasks, they all use worksurfaces that may cause problems if they are not at the right height and oriented properly.
Different tasks require different workstation setups.
However, they all have similar reference points. This serves as a guideline to determine the height of the workstation. For instance, the majority of work is done 2-3 inches below elbow height. This includes tasks like writing, some computer work, stirring dinner, and light assembly. Thus, all of our examples above can use this guideline to setup their workstations.
