The purpose of this study is to explore crowdsourcing as a research paradigm for creating evidence-based practice research in the field of speech pathology. Using an Internet survey, respondents provided de-identified information about one patient with aphasia they had treated in the previous year. The respondents were then asked to rate the success of treatment. Analysis and grading of the responses was performed to identify which responses were usable for the purpose of planning a treatment for a patient with similar demographics and diagnostic make-up. Results showed that crowdsourcing is a viable research method; however, further refinements to the collection and analysis are required before it can be an effectively used. / text

Background: Performance stability is an implicit assumption within theoretical explanations of aphasia. The assumption being that when completing language processing tasks, performance will be stable from moment to moment and day to day. Theoretically, aphasia is most commonly viewed within a modular framework. that is, language processing is carried out by specific, specialised language processing modules. Aphasia is thought to result when one of these modules is dammed leading to a unique pattern of performance results. Implicit to this view of aphasia is stability, once damaged, the module will no longer be accessed and any process using the module will be impaired. This theory of aphasia is widely held within both research and clinical communities and underlies many of our approaches to the assessment and treatment of aphasia. However more recently researchers have been expressing doubts about the validity of assuming stability in aphasia performance. Instead variability in performance is being reported and alternative explanations of aphasia are being provided. One of these considers aphasia to result from a reduction in or the inefficient allocation of cognitive resources. Aims: This research explored variability in aphasic performance, with the aim to examine variability over a range of tasks and time periods. Methods and Procedures: Eight aphasic and ten non-brain damaged individuals participated in eight sessions. Within these sessions they completed a spontaneous language task; which contained four different narrative genres. a lexical decision task and a simple reaction task.\ / Performance on these tasks was examined for three different levels of variability; inter session variability (across session means for time measures), intra session variability (across items for time measures) and inter session variability (item to item accuracy for lexical decision). The three different levels of variability examined performance on the same task across days and within the same task on the same day. To determine whether the change in the performance of aphasic individuals was in the same range and followed the same pattern of change and variation demonstrated by the non-brain damaged participants, the pooled results of the non-bruin damaged individuals' performance developed a 'normal' range of performance. Using the group's data the results of each of the aphasic individual was then converted to a z- score. Outcomes and results: The results demonstrate that for all aphasic individuals, across the three tasks and three time periods examined, variability is a regular, if not universal feature of aphasia. Conclusions: Stability in aphasic performance cannot be assumed. Instead research and clinical approaches must establish stability or consider the impact of variability before conclusions about performance can be drawn. The presence of variability also calls into questions the traditionally held view that aphasia results from the selective impairment of specialised language processing modules. Instead an alternative mechanism for impairment must be considered. The resource allocation view of aphasia was explored and found to explain the performance of aphasic individuals within this study.

To suffer from aphasia could mean that a most important ability of human nature is lost and could therefore restrict the patient's communication ability. Therefore a higher standard is of importance in the non-verbal communication. Health professionals describe difficulties in understanding this form of communication. This causes disturbance in the interaction and nursing care cannot be adapted to the unique human being. The purpose of this literature review is to highlight and summarize existing research, describing how the various non-verbal communication channels are integrated, in nursing care to patients affected by stroke and aphasia. In the method of this literature review searches were made from the databases Cinahl and Medline. The 12 articles that were included has been quality examined and analyzed according to Friberg (2006). The results describe how the speaking body, support for the unique human being, bodily contact and relationships are important for the understanding of the nonverbal communication. The discussion revolves around how this understanding is formed in the interaction, to be able to see the unique human being and create relationships that provide external support for the human needs here and now. The four categories that are presented in this study may increase the knowledge of the studied phenomena and could also be the ground for further studies in this area.

Att drabbas av afasi kan innebära att en högst mänsklig förmåga går förlorad, vilket kan begränsa patientens kommunikationsmöjligheter. Därmed ställs högre krav på den icke verbala kommunikationen. Vårdpersonal beskriver svårigheter att skapa förståelse i denna form av kommunikation. Till följd av detta blir samspelet lidande och omvårdnaden kan därför inte anpassas till den unika människan. Syftet med denna litteraturöversikt är att belysa och sammanställa befintlig forskning, som beskriver hur olika icke verbala kommunikationsvägar integreras, i omvårdnaden till patienter som drabbats av stroke med afasi som följd. I metoden genomfördes sökningar i databaserna Cinahl och Medline. De 12 artiklar som inkluderats har kvalitetsgranskats och analyserats enligt Friberg (2006). I resultatet beskrivs hur den talande kroppen, stödet till den unika människan, kroppslig beröring och relationen har betydelse för förståelsen i den icke verbala kommunikationen. Diskussionen kretsar kring hur denna förståelse kommer i samspelet, för att se den unika människan och skapa relationen som ger stöd utifrån människans förutsättningar här och nu. De fyra kategorier som framläggs i denna studie kan öka kunskapen inom det fenomen som studerats och lägga grunden för vidare studier på området. / To suffer from aphasia could mean that a most important ability of human nature is lost and could therefore restrict the patient's communication ability.

Functional neuroimaging research on language recovery in patients with aphasia due to left hemisphere damage has generated some intriguing results. However, it is still not clear what role the right hemisphere plays in supporting language functions in chronic phase for patients with different site and size of lesion when different tasks are used. The present study was aimed at exploring the role of perilesional, ipsilesional and contralesional regions in neural recovery in participants with aphasia with different site and size of lesion using three different language tasks. All patients in the present study were in the chronic stage who had achieved high levels of recovery. Functional magnetic resonance imaging (fMRI) was used to characterize cortical activation in eight stroke patients and eight age/gender matched controls during lexical decision, semantic judgment and picture naming. An event related design using jittered interstimulus intervals (ISIs) was employed to present the stimuli. The fMRI scans revealed differences in activation patterns across the three tasks. Normal control participants and participants with aphasia mainly activated the left perisylvian region during the lexical decision task and the semantic judgment task. However, during the picture naming task, all participants activated bilateral posterior regions irrespective of the site or size of lesion. Subsequent regions of interest analysis and laterality index analysis revealed that patients with larger lesions produced greater right hemisphere activation than patients with smaller lesions during the picture naming task. The results of this study demonstrate that recovery is task, lesion site and lesion size specific. Further, the findings of the present study indicate a role for both homologous contralesional cortex and perilesional and ipsilesional regions as efficient mechanisms for supporting language functions in chronic stroke patients. / text
