“…Our findings also carry interesting clinical implications. Gesture has been successfully deployed in a number of word finding treatments for PWA (e.g., Caute et al, 2013;Kroenke, Kraft, Regenbrecht, & Obrig, 2013;Marshall et al, 2012;Rose, Raymer, Lanyon, & Attard, 2013). This study may highlight its facilitative role in naturally occurring conversation.…”

The use and function of gestures in word-finding difficulties in aphasia Background: Gestures are spontaneous hand and arm movements that are part of everyday communication. The roles of gestures in communication are disputed. Most agree that they augment the information conveyed in speech. More contentiously, some argue that they facilitate speech, particularly when word finding difficulties occur. Exploring gestures in aphasia may further illuminate their role. Aims: This study explored the spontaneous use of gestures in the conversation of participants with aphasia (PWA) and neurologically healthy participants (NHP). It aimed to examine the facilitative role of gesture by determining whether gestures particularly accompanied word finding difficulties and whether or not those difficulties were resolved. Methods & Procedures: Spontaneous conversation data were collected from 20 PWA and 21 NHP. Video samples were analysed for gesture production, speech production, and word-finding difficulties. The first analysis examined whether the production of semantically rich gestures in these conversations was affected by whether the person had aphasia, and/or whether there were difficulties in the accompanying speech. The second analysis identified all word finding difficulties in the data and examined whether these were more likely to be resolved if accompanied by a gesture, again for both groups of participants. Outcomes & Results: Semantically rich gestures were frequently employed by both groups of participants, but with no effect of group. There was an effect of the accompanying speech, with gestures occurring most commonly alongside resolved word finding difficulties. An interaction showed that this was particularly the case for PWA. NHP, on the other hand, employed semantically rich gestures most frequently alongside fluent speech. The second analysis showed that word finding difficulties were common in both groups of participants. Unsurprisingly, these were more likely to be resolved for NHP than PWA. For both groups, resolution was more likely if the word finding difficulty was accompanied by a gesture. Conclusions: These findings shed light on the different functions of gesture within conversation. They highlight the importance of gesture during word finding difficulties, both in aphasic and neurologically healthy language, and suggest that gesture may facilitate word retrieval.

“…A third perspective is the use of gestures in the absence of speech: pantomime. Studies have shown that PWA are able to produce pantomimes (Hogrefe et al, 2013;van Nispen, van de Sandt-Koenderman, Mol, & Krahmer, 2014, 2016 and that PWA can be trained to produce a set of pantomimes (Caute et al, 2013;Kroenke, Kraft, Regenbrecht, & Obrig, 2013;Marshall et al, 2012;Rose & Douglas, 2006;Rose, Raymer, Lanyon, & Attard, 2013). The present study focuses on all gestures that PWA produced during a semistructured interview.…”

Part of the message comes in gesture: how people with aphasia convey information in different gesture types as compared with information in their speech

et al. 2017

Background: Studies have shown that the gestures produced by people with aphasia (PWA) can convey information useful for their communication. However, the exact significance of the contribution to message communication via gesture remains unclear. Furthermore, it remains unclear how different gesture types and representation techniques impact message conveyance. Aims: The present study aimed to investigate the contribution of gesture to PWA's communication. We specifically focussed on the degree to which different gesture types and representation techniques convey information absent in the speech of PWA. Methods & Procedure: We studied the gestures produced by 46 PWA and nine non-brain-damaged participants (NBDP) during semi-structured conversation. For each of the different types of gestures and representation techniques we identified whether these conveyed essential information, that is information that was absent in speech. Rather than looking at information that was either similar to information in speech or additional to information in speech, we focused on the essential gestures only. Outcomes & Results: For PWA, a fifth of their gestures were Essential. Despite individual differences between PWA, the majority produced more Essential gestures than NBDP, who produced limited amounts of Essential gestures. Essential information was mostly conveyed by specific gesture types: Pointing, Emblems and Iconic gesture. Within the group of iconic gestures, not only Handling and Enact but also Object and Shape gestures, were often Essential. Conclusions: Our findings suggest that a great proportion of gestures produced by most PWA convey information essential for understanding their communication. In their communication advice, speech language therapists could draw attention to specific gesture types to make sure that interlocutors pay more attention to these gestures when communicating with PWA.

“…This result is consistent with others from the literature showing similar benefits across types of facilitation techniques (Greenwald et al, 1995;Holland et al, 2018;Neumann, 2018;Stimley & Noll, 1991;Wambaugh, 2003;Wambaugh et al, 2001). This does not mean that all types of facilitation are equally effective for PwA with different kinds of impairment (although relationships are not always transparent; see Boo & Rose, 2011;Kroenke et al, 2013;Lorenz & Ziegler, 2009). In a mixed group, however, it is not surprising to see no differences in average benefits.…”

“…However, both naming therapies focused on phonological and semantic cueing have shown to be effective, probably because both of them help to strengthen links between phonological and semantic representation in lexical networks (for phonological therapies, see Hillis, 1993Hillis, , 1998Nickels, 2002;Raymer, Thompson, Jacobs, & Le Grand, 1993; for semantic therapies, see Boyle, 2004;Coelho et al, 2000;Nickels, 2002;Raymer et al, 1993; for a review of the efficacy of semantic feature analysis to improve picture naming, see also Maddy et al, 2014). There is also some evidence that practicing picture naming in association with gestures (observed or carried out) is effective, especially for PwA with lexical retrieval difficulties (Boo & Rose, 2011;Kroenke, Kraft, Regenbrecht, & Obrig, 2013;Marangolo et al, 2010;Rose, 2013;Rose & Douglas, 2008;Rose, Douglas, & Matyas, 2002) and that PwA can use gestures to self-cue while naming (Hanlon, Brown, & Gerstman, 1990;Lanyon & Rose, 2009). Gestures may help naming because of possible relationships between lexical representations and associated motor patterns (see embodied cognition; e.g., Jirak, Menz, Buccino, Borghi, & Binkofski, 2010;Pulvermüller, 2005).…”

Playing a team game improves word production in poststroke aphasia

Background: High intensity, one-to-one rehabilitation therapy is effective in the treatment of poststroke aphasia, but it can put strain on public health providers, as well as lead to high attrition. Working within a group of peers may be efficient for professional speech and language therapists, as well as reduce feelings of isolation and lack of confidence in patients, which can negatively affect progress. Evidence-based, structured group-based approaches, however, are lacking. Aims: We wanted to assess the feasibility a new group-delivered game-based intervention, designed to provide efficacious wordretrieval rehabilitation, in a cost-effective and motivating environment. Method & Procedure: Two cohorts of six participants took part. Each was split into two teams to play language games where pictures were named with the help of team members and facilitation from a speech and language therapist. Facilitation was varied in three different cueing conditions: phonemic, gesture + phonemic, and semantic + phonemic. Overall, 180 words were practiced (90 nouns and 90 verbs). Therapy was delivered 3 days per week, for 6 weeks (for a total of 54 hr). Outcomes & Results: Our intervention was equally effective across the three cueing conditions and for nouns and verbs. Gains were demonstrated in naming the pictures used in training, but also in the description of pictured scenes designed to elicit the same words. With these tasks, there were improvements of 25% and 18% from base-line accuracy, which compares well with gains reported in the literature using individually delivered speech and language therapy based on picture naming. Improvements were mostly maintained at both 4-7 weeks and 6-months post-therapy and were significant in all but the two most severely affected participants. There was some generalization of gains to narrative production, but not to other language tasks, nor to untreated words in picture naming. These positive language outcomes were combined with a high level of engagement and satisfaction (with participants stating a preference for games over standard therapy). Conclusions: Our results support embedding theoretically and empirically based techniques for aphasia rehabilitation within games with a strong social aspect, which may promote linguistic ARTICLE HISTORY
