Uso de modelos formais em sistemas pervasivos de cuidados de saúde: um estudo de caso em auxílio à prática de exercícios físicos.

Abstract

Several software solutions have been developed for the healthcare area. In this area, we high light the area of physical exercise that has received great attention from World Health Organization for helping decreasing risk of various diseases and improving the quality of life of people affected by some of them. However, there are three main problems with such solutions developed for monitoring of physical exercises: i) only physiological variables are supported, ii) professional attention is required during the exercise, and iii) customized recommendations are not given. In this work,we present a method to provide accordance maintenance between individuals actions and recommendations from health care professional, during the exercise execution, without the presence of himin loco. Such a method makes it possible to build a finite automaton model. Such an automaton, called reference model, describes how an individual must behave aiming to follow recommendations from the health care professional. As it is obtained by means of composition from smaller models, the model evolution is accomplished and properties are guaranteed by means of building process. Besides, liveness and safety properties are checked in the model by the model checking technique,making the model more reliable. Some tasks were performed during the evaluation process and showed that: the building process of the reference model is according to the clinical procedure; the generated reference model is able to represent the knowledge of the health care professional by providing appropriate recommendations; the presented solution is technically feasible to be developed and executed; and such a method can be used in real scenarios, since individuals are not under stress conditions.
