People with global aphasia (PwGA) post stroke have little to no meaningful communication abilities (ie limited comprehension, spoken language, reading and writing abilities).A proportion of PwGA will also have limited abilities to use any alternative means of communication e.g. gesture, pictures or computer devices. There is a suggestion in the literature that this is because of co-occurring cognitive deficits. The consequence is that these clients are unable to reliably communicate even their basic needs.This is commonly known as having no functional communication abilities. Such PwGA tend not to respond to standard speech and language therapy interventions.

This research will investigate the effect of a new cognitive intervention designed to improve basic functional communication abilities. The treatment will be nonverbal and involve computer and paperbased tasks ordered hierarchically from basic to more complex tasks. Six to eight participants will take part. All their sessions will take place in their own home. For some this may be a care home. They will first complete a diagnostic communication assessment in order for baseline abilities to be established. Further formal language and cognitive assessments will be conducted over a period of 6 weeks. A relative/friend will complete a questionnaires about mood/communication. The PwGA will also be videoed interacting with the research student e.g. looking at a magazine, completing a jigsaw, answering questions and making choices non-verbally.

The participants then receive the new intervention 3 times a week for 6 consecutive weeks. All intervention sessions will be videoed. Then participants will be reassessed over 2 weeks using the same assessments as prior to the intervention. The questionnaire with their relative/friend and videoed activity session will also be repeated. After a twelve week break the participant will be videoed interacting with the research student complete some of the assessments again and their relative will re-complete the questionnaires.
