Abstract
Background/Objectives: Aphasia is a neurological condition affecting the ability to understand and/or express language fluently and accurately, and can occur following stroke, traumatic injuries, or other brain pathologies. The aim of the following study was to provide clinicians and researchers information regarding the existing assessment tools to assess aphasia. Methods: For this Systematic Review, PubMed, CINAHL, Web of Science, and Scopus were searched for articles published up to August 2024. Authors independently identified eligible studies based on predefined inclusion criteria and extracted data. The study quality and risk of bias were assessed using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist. Results: Of the 1278 publications identified and screened, 238 studies fell within the inclusion criteria and were critically reviewed, and 164 assessment tools were found and divided into 8 main domains; the most used tools were the Language Screening Test (LAST), the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39), the Oxford Cognitive Screen (OCS), and the Token test. Conclusions: This review has emphasized the need for agreement among researchers as to which tool must be studied or adapted to other national contexts to develop universal norms and standards.
