Thus, this application aims to provide a support tool in ergonomic investigations of jobs where there are overloads reports in upper limbs. This application is based on RULA method developed by McAtamney, L. and Corlett, E.N. (1993) RULA: The survey method for the investigation of upper limb work-related disorders. Applied Ergonomics, 24 (2), 91-99
