Developing a User-Centered Mobile Application Prototype: Bridging Lower-Limb Fracture Care from Skilled Nursing...

This study is part of the OsteoPorotic fracTure preventION System (OPTIONS) project which aims to develop an evidence-based mobile application for older adults transitioning from skilled nursing facilities (SNFs) back to the community after lower limb fractures. The app promotes exercise, nutrition, and bone health medications to prevent future fractures. Using a Design science framework, app requirements were identified by synthesizing scientific knowledge, clinical expertise, and end-user needs. An initial mockup was developed based on these specifications and iteratively refined through design sessions incorporating end-user feedback. The final OPTIONS app features four core functions: (1) task-based self-management support, (2) personalized exercises and education, (3) motivational messaging, and (4) progress tracking allowing users to monitor their progress through visualizations. By addressing usability challenges for older adults, the app provides a personalized, engaging experience for continuous health management.
