    Co-Authors: Wallace, Sarah J., Power Emma, Brandenburg Caitlin, Baker Caroline, Bryant Lucy, Le Dorze Guylaine, Pritchard Madeleine, Rose, Miranda L., Rose Tanya, Ryan Brooke
    Abstract:

    Background: This article recognises Professor Linda Worrall’s contribution to Aphasiology and discusses research themes which have grown from her work. Aims: To review, summarise, and discuss literature relating to four themes which have emerged from the work of Professor Worrall: (1) Research capacity building; (2) Implementation of research evidence in clinical practice; (3) Meaningful outcome measurement; and (4) Improvement of psychological and emotional outcomes. Main contribution: A review of the literature, with examples of practical applications. Conclusions: The work of Professor Worrall has greatly influenced the field of aphasia; her legacy is the research capacity she has built in Australia and around the worl

  • Closing the evidence-practice gaps in aphasia management: are we there yet? Where has a decade of implementation research taken us? A review and guide for clinicians
    ePublications@SCU, 2018
    Co-Authors: Shrubsole Kirstine, Worrall Linda, Power Emma
    Abstract:

    Background: There are evidence-practice gaps in all areas of aphasia management across the continuum of care. Despite the recognition that effective implementation strategies are needed to improve the consistency of speech pathologists’ aphasia management practices, there have been few studies investigating this important issue. Therefore, little is known about the effectiveness of implementation strategies in the field of Aphasiology. In light of the developing field of knowledge translation, it is important to review the aphasia implementation literature to highlight current trends, draw together findings, and determine future implementation research needs. Aims: To critically review, summarise, and discuss the implementation literature in the field of Aphasiology to date, in order to guide clinical aphasiologists to work towards closing the evidence-practice gaps in aphasia management. Main contribution: A review of the literature in this developing area of expertise in the field of Aphasiology, with examples of practical applications. Conclusions: Only six implementation studies have been published in aphasia (related to conversation partner training, discourse analysis, information provision, and collaborative goal-setting practices), showing there is a need for capacity building in this area. Therefore, we are not yet able to state what interventions are effective in which context, nor fully understand how behaviour change occurs for clinicians providing aphasia management. Implications for speech-language pathologists are discussed. An overarching call to action is the need for clinicians and researchers to work together to drive future implementation efforts that can succeed in closing the aphasia management evidence-practice gaps

  • an aphasia database on the internet a model for computer assisted analysis in Aphasiology
    Brain and Language, 2000
    Co-Authors: Hubertus Axer, Jan Jantzen, Diedrich Graf V. Keyserlingk
    Abstract:

    A web-based software model was developed as an example for data mining in Aphasiology. It is used for educating medical and engineering students. It is based upon a database of 254 aphasic patients which contains the diagnosis of the aphasia type, profiles of an aphasia test battery (Aachen Aphasia Test), and some further clinical information. In addition, the cerebral lesion profiles of 147 of these cases were standardized by transferring the coordinates of the lesions to a 3D reference brain based upon the ACPC coordinate system. Two artificial neural networks were used to perform a classfication of the aphasia type. First, a coarse classification was achieved by using an assessment of spontaneous speech of the patient which produced correct results in 87% of the test cases. Data analysis tools were used to select four features of the 30 available test features to yield a more accurate diagnosis. This classifier produced correct results in 92% of the test cases. The neural network approach is similar to grouping performed in group studies, while the nearest-neighbor method shows a design more similar to case studies. It finds the neurolinguistic and the lesion data of patients whose AAT profiles are most similar to the user's input. This way lesion profiles can be compared to each other interindividually. The Aphasia Diagnoser is available on the Web address http://fuzzy.iau.dtu.dk/aphasia.nsf and thus should facilitate a discussion about the reliability and possibilities of data-mining techniques in Aphasiology.

  • the aphasia database on the web description of a model for problems of classification in medicine
    2000
    Co-Authors: Hubertus Axer, Jan Jantzen, Georg Berks, D Südfeld
    Abstract:

    In Aphasiology many inconsistencies exist in the definition and interpretation of aphasic syndromes. These syndromes are the co-occurrence of a set of symptoms. Thus, ambiguities in these clinical, aphasic categories are suited to be generalized to many problems of classification in medicine. In this paper the aphasia database is launched as a model for data mining in medicine. Nominal and topological data about 265 aphasic patients is collected in this database, which is a model for benchmarking different methods of soft computing.

  • sigmund freud and the diagram maker school of Aphasiology
    Brain and Language, 1992
    Co-Authors: Victor W Henderson
    Abstract:

    Published 100 years ago, Freud's monograph on aphasia, Zur Auffassung der Aphasien, is an incisive analysis of the so-called diagram-makers, those aphasiologists who would reduce brain and language to simple schemes of circumscribed cortical centers linked by unidirectional subcortical pathways. Chief architects of the diagram-maker school were Wernicke and Lichtheim, and their formulations of conduction aphasia and the transcortical aphasias were particular targets of Freud's trenchant criticism. Freud argued against functional differentiation within left hemisphere perisylvian language regions, and he suggested that traditional aphasic syndromes were artifacts of lesions that included cortical language regions and deeper white matter pathways not directly involved with language. He provided an innovative classification of aphasia based on types of associations presumed to be affected. Freud, however, failed to adduce new clinical or pathological observations; he was perhaps unnecessarily harsh in challenging authorities in the field of aphasia; and his theory had to compete with a straightforward and already entrenched anatomical view of language representation. Despite Freud's lucid argumentation, his carefully crafted monograph was never widely noted.
