Using codesign to develop a mobile application for pelvic floor muscle training with an intravaginal device (femfit (R))

Aims The aim of this project was to use codesign to develop a mobile application (app) for pelvic floor muscle training, with an intravaginal device (femfit (R)). The objective was to obtain user feedback to guide the design and development of a mobile app, consistent with the Mobile Application Rating Scale (MARS) framework. Methods Twenty-six women (22-62 years) provided mobile app feedback using a Design Thinking framework and grounded theory approach. Four focus groups (2 h each) and two sets of one-to-one interviews (1 h each) were held from May 2018 to October 2019. The researchers debriefed the focus groups and interviews, and undertook analysis based on project objectives and key questions. Results Recurring themes throughout the study aligned with sections of the MARS: (A) engagement (e.g., progress tracking), (B) functionality (e.g., intuitive interface), (C) aesthetics (e.g., smart graphics and colors), (D) information (e.g., clear, concise information). An internal preliminary assessment determined a MARS Quality Mean Score of 4.1 of 5 (engagement: 3.6 of 5; functionality: 4 of 5; aesthetics: 4.3 of 5: information: 4.4 of 5). Conclusions The development of the mobile app is on track to meet MARS requirements, and to be a fun, motivating app for women. Future work is required to investigate its efficacy.
