Constraint-induced or multi-modal personalized aphasia rehabilitation (COMPARE): A randomized controlled trial for stroke-related chronic aphasia

Abstract

Rationale: The comparative efficacy and cost-effectiveness of constraint-induced and multi-modality aphasia therapy in chronic stroke are unknown. Aims and hypotheses: In the COMPARE trial, we aim to determine whether Multi-Modal Aphasia Treatment (M-MAT) and Constraint-Induced Aphasia Therapy Plus (CIAT-Plus) are superior to usual care (UC) for chronic post-stroke aphasia. Primary hypothesis: CIAT-Plus and M-MAT will reduce aphasia severity (Western Aphasia Battery-Revised Aphasia Quotient (WAB-R-AQ)) compared with UC: CIAT-Plus superior for moderate aphasia; M-MAT superior for mild and severe aphasia. Sample size estimates: A total of 216 participants (72 per arm) will provide 90% power to..
