This work aims at providing a tool for supporting cognitive
rehabilitation. This is a wide field, that includes a variety of diseases and
related clinical pictures; for this reason the need arises to have a tool
available that overcomes the difficulties entailed by what currently is the most
common approach, that is, the so-called pen and paper rehabilitation. METHODS: We
first organized a big number of stimuli in an ontology that represents concepts,
attributes and a set of relationships among concepts. Stimuli may be words,
sounds, 2D and 3D images. Then, we developed an engine that automatically
generates exercises by exploiting that ontology. The design of exercises has been
carried on in synergy with neuropsychologists and speech therapists. Solutions
have been devised aimed at personalizing the exercises according to both
patients' preferences and performance. RESULTS: Exercises addressed to
rehabilitation of executive functions and aphasia-related diseases have been
implemented. The system has been tested on both healthy volunteers (n = 38) and
patients (n = 9), obtaining a favourable rating and suggestions for improvements.
CONCLUSIONS: We created a tool able to automate the execution of cognitive
rehabilitation tasks. We hope the variety and personalization of exercises will
allow to increase compliance, particularly from elderly people, usually neither
familiar with technology nor particularly willing to rely on it. The next step
involves the creation of a telerehabilitation tool, to allow therapy sessions to
be undergone from home, thus guaranteeing continuity of care and advantages in
terms of time and costs for the patients and the National Healthcare System
(NHS). Implications for rehabilitation Cognitive impairments can greatly impact
an individual's existence, appreciably reducing his abilities and autonomy, as
well as sensibly lowering his quality of life. Cognitive rehabilitation can be
used to restore lost brain function or slow down degenerative diseases.
Computerization of rehabilitation entails many advantages, but patients -
especially elderly people - might be less prone to the use of technology and
consequently reluctant towards this innovative therapeutic approach. Our software
system, CoRe, supports a therapist during the administration of rehabilitation
sessions: exercises can be generated dynamically, thus reducing repetitivity, and
patients' performance trends automatically analysed to facilitate the assessment
of their progress. Tests performed on both healthy subjects and patients provided
useful information that allowed us to define an implementation strategy able to
reduce patients' resistance to computerized rehabilitation as much as possible.
