The rehabilitation department of the Mobile Hospital Team at Region Skåne Malmö wants to convert the current traditional training programs, given to patients on a piece of paper, into something digital. For the following purpose, an online cross-platform web application called WeeDo was implemented. This thesis researched to what extent this tool can replace traditional forms of rehabilitation, how well physiotherapists can track the improvement and engagement of their patients from a distance, and what functionalities are important to make the system effective and useful. A field study along with a semi-structured interview and questionnaires were invoked to conduct data from the users of the application. 32 patient proxy users participated in the questionnaires and 1 physiotherapist in the interview. The results from the questionnaires found that a visual representation of exercises is valuable and important. 91.3% of the patient respondents felt that WeeDo can replace the traditional form of physiotherapy. The interview results found that WeeDo will not only be similarly effective as the traditional physiotherapy but WeeDo will also let physiotherapists to track patients' improvement and engagement from a distance. However the study includes some limitations and recommendations for future research to validate similar conclusions that can be drawn from this study.
