“…There was no significant change in the number of facilitators for the group (minimal numerical increase from 33.7 to 35.7 on average in 5 min of conversation). This is a new finding and it stands alone as, while there are some well controlled case studies in the literature (Carragher et al, 2015), there is no research examining change at a group level in conversation behaviors after an intervention with a direct focus on conversation. The differing findings for the experimentally controlled case series are important in highlighting the variability between dyads making up the group.…”

“…Whilst there is evidence that grammatical ability in the clinical setting can be improved in this way, it has proved hard to detect carryover to everyday conversation; indeed there are few studies where this is explicitly evaluated. It may be that generalization occurs but much research has failed to capture it (Carragher et al, 2015). In the field of anomia therapy, there is evidence that work on retrieving single words can influence connected speech tasks and conversation (Conroy et al, 2009; Best et al, 2011).…”

Conversation therapies employing video for feedback and to facilitate outcome measurement are increasingly used with people with post-stroke aphasia and their conversation partners; however the evidence base for change in everyday interaction remains limited. We investigated the effect of Better Conversations with Aphasia (BCA), an intervention that is freely available online at https://extend.ucl.ac.uk/. Eight people with chronic agrammatic aphasia, and their regular conversation partners participated in the tailored 8 week program involving significant video feedback. We explored changes in: (i) conversation facilitators (such as multi-modal turns by people with aphasia); and (ii) conversation barriers (such as use of test questions by conversation partners). The outcome of intervention was evaluated directly by measuring change in video-recorded everyday conversations. The study employed a pre-post design with multiple 5 minute samples of conversation before and after intervention, scored by trained raters blind to the point of data collection. Group level analysis showed no significant increase in conversation facilitators. There was, however, a significant reduction in the number of conversation barriers. The case series data revealed variability in conversation behaviors across occasions for the same dyad and between different dyads. Specifically, post-intervention there was a significant increase in facilitator behaviors for two dyads, a decrease for one and no significant change for five dyads. There was a significant decrease in barrier behaviors for five dyads and no significant change for three dyads. The reduction in barrier behaviors was considerable; on average change from over eight to fewer than three barrier behaviors in 5 minutes of conversation. The pre-post design has the limitation of no comparison group. However, change occurs in targeted conversational behaviors and in people with chronic aphasia and their partners. The findings suggest change can occur after eight therapy sessions and have implications for clinical practice. A reduction in barrier behaviors may be easier to obtain, although the controlled case series results demonstrate a significant increase in conversation facilitators is also possible. The rehabilitation tool is available online and video technology was central to delivering intervention and evaluating change.

“…Aphasia classification was based on clinical consensus, grammatically impoverished output on picture description tasks, and performance on standardised language assessments (Table 1; for more details see Carragher et al, 2013, p. 852;Beeke, Maxim, Best, & Cooper, 2011, p. 228). Dyads took part in intervention studies (dyads 1-8: Carragher et al, 2013;Carragher, Sage, & Conroy, 2015;dyad 9: Best et al, 2016) and recorded weekly conversations prior to, during and after intervention. Analysis is based on pre-therapy recordings only and the nature of interventions is not relevant to the current study.…”

“I don’t know”: a usage-based approach to familiar collocations in non-fluent aphasia

et al. 2018

Background: Familiar collocations (e.g., "it's alright") are an important part of everyday conversation. Such word combinations are often retained in speakers with Broca's aphasia. However, only few investigations have studied the forms and functions of familiar collocations available to speakers with Broca's aphasia. Aims: We first apply a frequency-based perspective to word combinations produced by speakers with Broca's aphasia and their conversation partners (CPs), and compare the frequency characteristics of word combinations in dyadic and non-dyadic speech. Second, we investigate the conversational functions of one prominent familiar collocation, "I don't know" (IDK). Methods & Procedures: In the first analysis, speech samples from interactions of nine dyads (each a speaker with Broca's aphasia and their CP) were examined. Non-dyadic samples were selected from 39 speakers with Broca's aphasia from AphasiaBank (MacWhinney et al., 2011). The Frequency in Language Analysis Tool (FLAT; Zimmerer & Wibrow, 2015) was used to estimate collocation strength (the degree of association between words in a combination) of well-formed bigrams (two-word combinations) and trigrams (three-word combinations). The second analysis presents a qualitative investigation of uses of IDK in dyadic exchanges. Outcomes & Results: Analysis 1 revealed that residual trigrams in Broca's aphasia were more strongly collocated in comparison to language produced by CPs. There was no difference in frequency-based profiles between dyadic and non-dyadic aphasic speech. Analysis 2 indicated that speakers with Broca's aphasia and CPs used IDK to achieve a variety of communicative functions. However, patterns specific to each participant group were found. Conclusions: These findings highlight that frequency-based analysis is useful in explaining residual, grammatically well-formed word combinations in Broca's aphasia. This study provides evidence that IDK can aid turn construction in aphasia.

“…A 2002 study (48) reported that gains in generalization are limited, as observed in some of the selected studies (24,36,37,39,42) . However, findings from some studies of this review have shown that participants treated within this approach had gains in generalization to untrained items (13,15,19,28,32) .…”

RESUMO Introdução Por meio da intervenção fonoaudiológica, é possível diminuir os sintomas da afasia. Objetivos Verificar os métodos de intervenção fonoaudiológica na afasia expressiva. Estratégia de pesquisa Trata-se de uma revisão integrativa da literatura. Realizou-se a busca nas bases SciELO, PubMed e PsycINFO, no período de fevereiro a abril de 2018. Para as bases de dados PubMed e PsycINFO foram estabelecidos os descritores em inglês “non-fluent aphasia”, OR “broca” OR “transcortical motor aphasia” OR “motor aphasia” OR “amnestic aphasia” OR “semantic aphasia” OR “dymanic aphasia” OR “anomi*” AND “intervention” OR “therapy” OR “rehabilitation” OR “treatment”. Para base SciELO, apenas o descritor “aphasia”. Critérios de seleção Artigos publicados nos últimos dez anos (de 2009 a 2018) em português, inglês ou espanhol foram incluídos, sendo ou não de periódicos de acesso livre, além de estudos com indivíduos com idade superior a 19 anos. Foram excluídos artigos não relacionados à terapia tradicional, estudos que não apresentassem indivíduos com afasia expressiva e aqueles que tratavam de distúrbios motores de fala, como disartria e apraxia pura. Estudos de revisão de literatura e que envolvessem participantes bilíngues também foram excluídos. Resultados Um total de 174 artigos foram encontrados. Após análise e aplicação dos critérios de seleção estabelecidos, foram selecionados 32 artigos completos. Entre as terapias tradicionais encontradas, observaram-se: terapia de recuperação de palavras, terapia melódica e terapia conversacional. Conclusão A terapia de recuperação de palavras foi o método tradicional mais utilizado.
