- Abstract
Purpose: The initial version of Constraint-Induced Aphasia Therapy (CIAT I) consisted of a single exercise. This study sought to evaluate the feasibility for future trials of an expanded and restructured protocol designed to increase the efficacy of CIAT I. Method: The subjects were 4 native English speakers with chronic stroke who exhibited characteristics of moderate Broca's aphasia. Treatment was carried out for 3.5 hr/day for 15 consecutive weekdays. It consisted of 3 components: (a) intensive training by a behavioral method termed shaping using a number of expressive language exercises in addition to the single original language card game, (b) strong discouragement of attempts to use gesture or other nonverbal means of communication, and (c) a transfer package of behavioral techniques to promote transfer of treatment gains from the laboratory to real-life situations. Results: Participation in speech in the life situation improved significantly after treatment. The effect sizes (i.e., d') in this domain were ≥ 2.2; d' values ≥ 0.8 are considered large. Improvement in language ability on a laboratory test, the Western Aphasia Battery—Revised (Kertesz, 2006), did not achieve statistical significance, although the effect size was large—that is, 1.3 (13.1 points). Conclusion: These pilot results suggest in preliminary fashion that CIAT II may produce significant improvements in everyday speech.
