Conscientização ergonômica e saúde do trabalhador: avaliação dos aplicativos de ergonomia e elaboração de protótipo de aplicativo ergonômico informativo

Abstract

The accession of work ergonomic practices acts in the prevention of work-related musculoskeletal diseases (MSDs), which are among the most frequent occupational diseases in Social Security statistics. Ergonomics awareness is a way of health education at work that promotes health, prevente injuries, increases workers autonomy in their care and encourages managers to fit work situation with ergonomic risk. Objectives: assess whether ergonomic mobile apps have content suitable for use in ergonomic awareness and design a prototype ergonomic awareness app. Methods: In the exploratory phase, informative or instructive apps selected from the apps listed in the search with the keywords ergonomics and ergonomics app in Portuguese, English and Spanish, on the Operating Systems (OS) Android and iOS. It was included in this study apps in these three languages, free or paid, with ergonomics for workers information or instruction. In the assessment phase, selected apps content were compared to the items of Regulatory Standard 17 (NR 17), considered the minimum parameters for ergonomic adequacy by Labor Secretary. In the prototyping phase, an app was created based on the working conditions approached in NR 17. Results: 42 ergonomics apps were found, the majority of which were designed to carry out ergonomic evaluations. Five of these apps were selected for the comparative assessment to NR 17, as they are informative. Two apps - ILO - Verification of Ergonomic Points and ErgoOffice, have the content of general work situations and only the first is in Portuguese. The analyzes between the content of these five apps and the items approached in NR 17, ILO apps – Verification of Ergonomic Points and Agriculture Checkpoints, show greater similarity to NR 17 with 54% and 42% of related themes, respectively. Sergomater, ErgoOffice and Automotive Design apps follow, with 38%, 19% and 12% of similarity. These analyzes indicate that the ILO - Verification of Ergonomic Points app is the one that showed greater similarity with the aspects approached in NR 17, however 46% of the recommendations of NR 17 items were not addressed, in addition to the fact that this app contains other information besides the Ergonomics. Conclusions: ILO Ergonomic Points Verification app was the most appropriate informational app for ergonomic awareness in production activities, as it is in Portuguese, addressing general conditions of productive activities and presenting more similarities with the aspects covered by NR 17. The results show that there is a lack of informational or instructional apps in Ergonomics, especially when related to the NR 17 parameters. For this reason, this study developed an instructive app prototype based on NR 17. The app aims to provide information and instructions for the ergonomic awareness of workers and companies, especially those that have difficulty to access this information.
