This has led to the development of a number of tools for the self-assessment of PROs with validated questionnaires. However, there is no tool that overcomes the constraints of standard tests such as the QMG while allowing for the collection of objective data and PROs between visits.\n\nME\\&MG is a standalone software (digital solution) running on patients smartphones, connected to a web portal for physicians.
