Abstract
Aphasia is a manifestation of the impact of stroke disease that affects communication abilities and occurs due to damage to the brain area that regulates the language center, precisely in the Broca and Wernicke areas. Verbal communication disorders affect the life and quality of life of post-stroke patients, hence various rehabilitative therapies have been developed, one of which is using Constraint Induced Aphasia Therapy. This study aims to systematically review the influence of Constraint Induced Aphasia Therapy on the communication abilities of aphasia patients due to stroke. The systematic review design uses electronic data sources such as PubMed, Sciencedirect, and ASHA Publications. Selected journals used keywords such as "Constraint Induced Aphasia Therapy" and "aphasia and stroke" with the following inclusion criteria: articles published from 2013–2023, with full texts in English, consisting of randomized controlled trials (RCT), patients with aphasia (verbal communication disorders), and interventions of Constraint Induced Aphasia Therapy capable of restoring verbal communication disorders. The provision of communication card therapy intervention affects the verbal communication abilities of aphasia patients due to stroke. The clear changes are seen in the understanding of the messages conveyed and the pronunciation of what wants to be expressed. The duration and follow-up period of care affect the long-term impact of the expected effects. Constraint Induced Aphasia Therapy is effective in improving verbal communication abilities. Through standardized communication assessment instruments for aphasia, it shows optimal results in improving verbal communication.
