Acquired Brain Injury (ABI) is becoming an epidemic problem in our society, especially among older adults, being known as “the Silent Epidemic”. People with ABI demand solutions in research that offer them with a relearning process such that they can recover not only their physical skills but also their cognitive abilities. In this context, the inherent characteristics of Ambient Intelligence (AmI), transparency and intelligence, have turned it into one of the best approaches to square up to the impairment that ABI can cause. As AmI proposes the development of context-aware systems that integrate different devices to recognize the context and act accordingly, these systems can react promptly to the needs of people with ABI while they carry out their rehabilitation process. Moreover, the exploitation of a Multi-Agent architecture emerges as a natural solution to develop AmI systems, since agents are reactive, proactive and exhibit an intelligent and autonomous behavior. Therefore, in this paper, a Multi-Agent architecture (MAS) for healthcare AmI systems is presented. It contributes to treat people with ABI by using specific devices to control the patient's movements and some physiological responses, such as the variation of the heart rate, during her rehabilitation process. In this way, the natural relationship between AmI and MAS is exploited. Finally, how this system is used to both design and execute therapies for people with ABI is presented. [ABSTRACT FROM AUTHOR]

Tele-rehabilitation is one of the main domains where Information and Communication Technologies (ICT) have been proven useful to move healthcare from care centers to patients' home. Moreover, patients, especially those carrying out a physical therapy, cannot use a traditional Window, Icon, Menu, Pointer (WIMP) system, but they need to interact in a natural way, that is, there is a need to move from WIMP systems to Post-WIMP ones. Moreover, tele-rehabilitation systems should be developed following the context-aware approach, so that they are able to adapt to the patients' context to provide them with usable and effective therapies. In this work a model-based approach is presented to assist stakeholders in the development of context-aware Post-WIMP tele-rehabilitation systems. It entails three different models: (i) a task model for designing the rehabilitation tasks; (ii) a context model to facilitate the adaptation of these tasks to the context; and (iii) a bio-inspired presentation model to specify thoroughly how such tasks should be performed by the patients. Our proposal overcomes one of the limitations of the model-based approach for the development of context-aware systems supporting the specification of non-functional requirements. Finally, a case study is used to illustrate how this proposal can be put into practice to design a real world rehabilitation task. [ABSTRACT FROM AUTHOR]
