Evidensbaserad logopedisk intervention vid strokeorsakad afasi hos vuxna : En verksamhetsknuten litteraturstudie
Background: The speech- and language deficit aphasia affects 12 000 persons annually in Sweden. Aphasia is caused by injury in the brain and the most common etiology is stroke. According to the tool for describing and assessing aphasia, A-FROM (Kagan et al., 2008), the four following aspects of aphasia need to be considered: severity of aphasia, participation in life situations, communication and language environment and personal factors. Several different interventions and treatments can be performed in every domain. There is scientific evidence for interventions performed by speech and language pathologists; however, the question is yet being discussed since results are unambiguous.
Purpose: The main purpose of this study is to investigate which aphasia interventions performed by speech and language pathologists that are supported by evidence. A further purpose is to visit clinical practices to obtain data concerning how speech and language pathologists work with persons with aphasia. Method: Systematic search for literature was executed in seven medical databases. Articles that met certain criteria were graded regarding evidence. The authors additionally made visits to speech and language pathologists at a hospital Svealand, Sweden, for observation and interviewing of speech and language pathologists.
Results and conclusions: The level of evidence for interventions varies. No intervention is investigated in more than three included studies and the number of participants is often small. Recommendations for clinical work can be given based on evidence from the included studies. The one intervention that was being studied by the most studies is CIAT/CILT. Interventions targeting expressive language, in particular word retrieval, have the strongest support in evidence.
