Evidensbaserad logopedisk intervention vid nedsatt hörförståelse hos personer med afasi : Ett systematiskt kunskapsunderlag

Sammanfattning: Among Swedish speech and language pathologists there is a need for extended knowledge of existing treatment methods for aphasia. Currently, there is an ongoing process to develop clinical guidelines for aphasia rehabilitation. Therefore, a knowledge base is needed, including a description of existing treatment methods, their theoretical foundation and evidence base. The aim of the present study was to compose an evidence-based summation of treatment methods for auditory comprehension disorder in people with aphasia. A systematic literature search was conducted using the following databases: PubMed, PsycINFO, Cochrane Library, CINAHL and Speechbite. Additionally, several studies were found by manual searches. Twenty-three articles were chosen and assessed. A total of 13 different treatment methods were described. Most of the included studies had a poor quality and few participants. The majority of the treatment methods were found to have an insufficient evidence base, with the exception of CIAT and Hand-action observation treatment. They were found to have moderate and limited evidence. Most of the included studies have shown a significant improvement of auditory comprehension following speech and language therapy. Although, for speech and language pathologists to be able to choose a specific treatment method based on evidence, larger studies with higher quality will be needed.
