Mobile application KneeCare to support knee rehabilitation

The main goal of this paper is to report on the research and development of a mobile solution KneeCare, which supports knee rehabilitation. We carried out an in-depth analysis of the common causes of knee injuries and the types of knee rehabilitation, as well as the state-of-the-art mobile technology and the usability aspects of a mobile application. This helped to structure the solution by providing a set of functional and nonfunctional requirements. They were evaluated in view of healthcare professionals, whose opinion was obtained from interviews and questionnaires. A design solution was formulated by creating a low fidelity and a high fidelity prototype. A number of tools and techniques were used to help implement a design solution such as Eclipse IDE. A number of tests such as black box and usability testing were carried out to evaluate if the user requirements have been met. A number of informal interviews were conducted to ensure that the application met the user´s needs. The results showed a positive reaction. The results from the usability tests showed the application has met 8 out of the 10 heuristics rules set by Nielsen.
