A computerised communication aid for people with aphasia.

PURPOSE: To develop a portable computerised communication aid for aphasic people to support communication in everyday life. METHOD: A multidisciplinary team of aphasiologists, augmentative and alternative communication specialists, speech and language therapists and technicians developed a portable, modular system, PCAD (portable communication assistant for people with dysphasia), running on a commercially available handheld computer. The system was tested in a multiple case study. Aphasia therapy services In the UK, Portugal and The Netherlands referred 28 people with aphasia, who were considered eligible for a computerised communication aid. Participants were trained following a protocol and used the device in self-chosen real life settings. RESULTS: Six of the 28 selected aphasic patients decided not to test the device; 22 participated in the training. All 22 learned to operate the aid, 17 used it functionally, in everyday life. Five people did not use the aid outside the therapy room, although they were able to operate the aid and to use it in role play. These unsuccessful clients were younger, and tended to have a shorter duration of the aphasia. CONCLUSIONS: Carefully selected aphasic patients may benefit from a computerised communication aid, using it functionally in everyday communicative settings.
