One third of the stroke sufferers experience long-term physical and/or cognitive disabilities, and stroke is considered to be the most common cause for severe disability and even death. Following a stroke incident, a significant proportion of patients can suffer from Apraxia and/or Action Disorganisation Syndrome (AADS) which, among other symptoms, is demonstrated by the impairment of cognitive abilities to carry out Activities of Daily Living (ADL) (Hermsdörfer, 2003; Goldenberg, 1998; Liepmann, 1908).
Most common rehabilitation systems are focused on treating physiological aspects of stroke, such as limb movement (Freeman, 2012), and are based on robot or virtual environment platforms which are expensive and not effective for a home base environment (Amirabdollahian, 2001; Kahn, 2001; Krebs, 2003; Shor, 2001). Furthermore, they are space dependent, requiring the patient to function within their working space rather than adapting to patient’s natural environment.
To date, most common rehabilitation systems that are based on Information and Communication Technologies (ICT) focus on treating physiological symptoms of stroke (e.g. muscle weakness) (Galiana, 2012; Kesner, 2011; Mao, 2010; Ueda, 2010). These systems are inappropriate for rehabilitation of the cognitive basis of AADS. Moreover, these systems tend to be expensive and so impractical for home installations. As a consequence, this affects the continuity of therapy and weakens its impact.
This paper presents a different solution whose contribution is part of a European project called CogWatch (http://www.cogwatch.eu/). The aim is to provide a rehabilitation system based on highly instrumented common objects and tools, wearable and ambient devices that are part of patients’ everyday environment and can be used to monitor behavior and progress as well as re-train them to carry out ADL through persistent multimodal feedback at home.
The document is divided into several sections. Section II presents a brief description of AADS patients and the effects of stroke. Once the main features of these patients are described, the physical description of the platform and how the system works are presented in section III and section IV in order to detail an experiment carried out to assess the solution adopted in section V. Finally, in section VI, a conclusion and brief summary of the general results are presented…
