Tools to aid ergonomic analysis are often used when there is need for evaluation of musculoskeletal risks at work. Of these tools, one of the most known is the REBA (Rapid Entire Body Assessment) tool. Its wide use has changed its form of distribution and application by several authors to try to find its best way of application. In addition, with the advent of cell phones and tablets, several versions of this tool’s apps were made. Few researches can be found about the usability of this method; also which version is most appropriate in terms of usability. The objective of this article is to evaluate the usability of the REBA tool in two different versions to verify the influence that such usability has on the results generated by it. It is believed that any type of tool that will be used for an ergonomic evaluation must, intrinsically, be usable, since its usability has a direct influence on its reliability and replicability. Thus, a comparative usability analysis of the tool on paper and app versions was performed with eight subjects to verify this usability. We found a better usability for the application, but similar reliability for the two versions. Thus, both can be used for REBA evaluation.
