Evidensbaserad logopedisk intervention vid nedsatt ordmobilisering hos personer med afasi : Ett systematiskt kunskapsunderlag för behandlingsmetoder

Sammanfattning: Background: In Sweden there is currently no comprehensive information with in-depth descriptions, as well as degree of evidence, of treatment methods for word-finding difficulties, in aphasia. Clinical speech-language pathologists therefore often lack knowledge about the treatment methods that exist, their theoretical basis, how to perform the treatment, for what patients the methods are appropriate and what evidence they have. Aim: The aim of this study was to compose an evidence-based summation with descriptions of treatment methods targeting word-finding difficulties for people with aphasia. Method: A systematic literature search for studies evaluating methods for treating word finding difficulties was conducted in September - October 2019. Searches were conducted in several databases and on the websites of the American Speech-Language-Hearing Association (ASHA) and Australian Aphasia Rehabilitation Pathway (AARP). Moreover, additional articles were hand searched. Articles that met the inclusion criteria were quality checked and the evidence strength for each method was assessed. Results: The majority of the included studies showed improved word-finding ability of the participants. However, most of the studies had few participants and were of a design that made it difficult to generalize the results and thus lower the evidence level. The assessment resulted in two treatment methods with moderately strong degree of evidence, one with limited evidence and four treatment methods with insufficient evidence. For one of the methods, the authors found no research and the evidence for that method could therefore not be assessed. Conclusion: To increase the degree of evidence of treatment methods for people with aphasia, more and larger studies with RCT design must be carried out.
