Constraint-Induced Aphasia Therapy (CIAT) has been found to be effective for treating persons with chronic aphasia. Modifications to the traditional activities of the CIAT protocol have been found to be successful using Constraint-Induced Aphasia Therapy Plus (CIAT II of CIAT-plus). Current literature lacks information on dosage parameters and feasibility of the CIAT protocol with caregiver participation in the acute phase of aphasia. The purpose of this investigation was to examine the effect of the CIAT II protocol on language deficits in individuals with acute aphasia.
