Although many studies investigate the automatic adaptation in serious games with the goal to improve the user's motivation, the most part of Affective Computing approaches requires a high development cost and usually does not consider an intervention of health professionals in the control of adaptations that will be executed in a game. This paper describes an approach to enable affective adaptation in serious games for motor rehabilitation with the involvement of physiotherapists. Our approach includes the definition and the implementation of a framework, whose architecture allows reducing the cost of implementation of a game with affective adaptation while enables physiotherapists to configure adaptations in a game according to patients' profile. An experiment was conducted with physiotherapists and the results show that the system presents a high level of acceptance.
