Extracting a design specification for a mHealth application for supporting adolescents in managing their ongoing onset knee pain, a qualitative exploration with low-fidelity prototypes.

The aim of this study is to explore how to design mHealth core-features which adolescents with knee pain will experience as useful, meaningful and an inspiration for self-management. Through a synthesis of findings from previous interventions, this study will use digital fidelity prototypes and think aloud usability testing to i) pinpoint different barriers for adolescents adapting the design and ii) identify current and latent information needs of adolescents with knee pain. The extracted insights will be synthesized to inform the formulation of a design principle for informing future mHealth designs, which can be tested with patients in clinical trials.
