Abstract

Aphasia as a common consequence of stroke, is an acquired neurologic communication disorder that can affect symbol language processing. Different types of intervention approaches have been introduced. Multimodal Communication Program (MCP) is a new augmentative alternative communication approach in chronic aphasia. The aim of this study was to investigate the effect of MCP on communication skills of patients with chronic aphasia. This prospective, single subject, A-B-A design study was done during 2016 in Semnan, Iran. Participants were two patients with severe aphasia with a single left-hemisphere stroke. Three phases, including baseline, intervention and follow-up were administered. The patients received nine-hour intervention, over 10 working days. Three different scores were calculated for each patient: verbal efforts, the frequency of each modality and the accuracy of switching between modalities and the reaction time. The frequency of verbal modality increased for both patients. They could switch between modalities more successfully than before the intervention. The results for the reaction time, however were challenging. The onset reaction time decreased for patient 1, and increased during switching between modalities, a...Continue Reading
