Abstract

Aphasia, a typically chronic language impairment that impacts expressive and receptive language but does not impact intelligence, occurs in approximately 30 - 40% of stroke survivors. Chronic aphasia negatively impacts functional communication, communicative participation, and psychosocial well-being in stroke survivors. Access to care during the post-acute phase of recovery is limited, requiring novel models of rehabilitation that are person-centered and holistic. The intensive comprehensive aphasia program (ICAP) model has shown proof-of-concept, feasibility, and acceptability to improve patient cognitive-linguistic outcomes, psychosocial well-being, and communicative participation. However, outcomes from an ICAP have not been compared to usual care aphasia therapy or to a new model of treatment known as the modified intensive comprehensive aphasia program (mICAP). This study investigated three models of service delivery for stroke survivors with post-acute aphasia: a 4-week, 84-hour ICAP; a 2-week, 24-hour mICAP; and an 8-week, 24-hour usual care condition. A sample of 18 participants with aphasia was recruited for this study (i.e., eight participants in the ICAP, six participants in the mICAP, and four participants in the usual care group). Comparisons were made to capture individual, within-group, and between group changes on standardized measures that represent constructs of language, functional communication, psychosocial well-being, and quality of life across each of the three conditions. Individual, within, and between-group differences are described. Results of this Phase I pilot study reveal more substantial positive changes present for the ICAP and mICAP groups compared to the usual care condition.
