Abstract
ABSTRACT Objective: to develop a multi-platform mobile application for the prevention of musculoskeletal risk factors related to nursing work in a hospital unit and to evaluate the usability criteria with nurses and computer professionals. Method: technological production study for the development of a mobile application, following the phases of software engineering: analysis of requirements, design and specification, construction, internal tests, maintenance and external evaluation. The product was evaluated for usability by nurses from public hospital units in the city of Rio de Janeiro (Brazil). The System Usability Scale instrument was used for the evaluation of the nurses and the instrument of heuristics of compliance of digital interfaces was used with the informational technology professionals. The application development period lasted from November 2017 to March 2018 and the usability assessment from March to May 2018. Results: the evaluation data showed that the application shows agreement and compliance with the principles of usability in the criteria of effectiveness, efficiency and user satisfaction, however, the evaluators suggest that the application's functionalities should be simplified. Conclusion: the application was designed as a care strategy for the nursing professional, considering the musculoskeletal risks which they are exposed to in their professional activities. The development and evaluation methods were satisfactory and the proposed objectives were achieved.

Summary
With the recognition and applicability of digital information and communication technologies in the various areas of knowledge, it is necessary to rethink the possibilities and demands in this complex global space for health actions. With the spread of the wireless internet via mobile devices, especially cell phones, eHealth has evolved into a new field, mHealth (mobile health),[2] which, due to its mobility, portability, functionality and connectivity, has become a technology that brings together a growing variety of health, operational, managerial and decision support applications, in conversation networks for prevention, promotion, disease control, surveillance, and monitoring.[3,4,5] The potential of mobile digital technologies applied to health care, both from the point of view of citizens and from the point of view of institutions, is critically important as it broadens the design of the care environment, a mobile space of interactions interconnecting contexts, subjects and knowledge, where care and education walk together gaining prominence and relevance In this context, combining the categories of work, worker and health, studies carried out in several countries, show a prevalence of work-related musculoskeletal disorders among nursing professionals[6,7,8,9] such as injuries to muscles, tendon, nerves, joints and ligament and have a complex multifactorial origin. In the last ten years, it has been the top disease which has received the most welfare aid.[11]
