Abstract
PURPOSE This study aimed to evaluate the effects of symbolic gestural training on enhancing recovery of spoken naming in people with aphasia (PWA) using a systematic review and meta-analysis. METHOD Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, article search was conducted from four databases: Web of Science Core Collection, Medline, PsycINFO, and EBSCO. A total of 45 participants from four studies investigating the symbolic gestural training effects on PWA and outcome measures of spoken naming were included. RESULT The meta-analysis showed a medium overall effect of symbolic gestural training on enhancing recovery of spoken naming in PWA. Subgroup analysis also revealed that the training effect was more remarkable in the gesture + verbal training paradigm than in the gesture-only training paradigm. However, the differences in the training effects between short and long duration, and training supplied with and without feedback, were nonsignificant. CONCLUSION This study illustrates the current state of the literature on symbolic gestural training in PWA, and serves as a reference for clinicians, patients, and health policy-makers regarding the application of symbolic gestural training in clinical or rehabilitation programs.

Abstract
PURPOSE If language production is impaired, will gestures compensate? Evidence in favor of this prediction has often been argued to come from aphasia, but it remains contested. Here, we tested whether thought content not present in speech due to language impairment is manifested in gestures, in 20 people with dysfluent (Broca's) aphasia, 20 people with fluent (Wernicke's) aphasia, and 20 matched neurotypical controls. METHOD A new annotation scheme was created distinguishing types of gestures and whether they co-occurred with fluent or dysfluent/absent speech and were temporally aligned in content with coproduced speech. RESULTS Across both aphasia types, noncontent (beat) gestures, which by their nature cannot compensate for lost speech content, constituted the greatest proportion of all types of gestures produced. Content (i.e., descriptive, referential, and metaphorical) gestures were largely coproduced with fluent rather than dysfluent speech and tended to be aligned with the content conveyed in speech. They also did not differ in quantity depending on whether the dysfluencies were eventually resolved or not. Neither aphasia severity nor comprehension ability had an impact on the total amount of content gesture produced in people with aphasia, which was instead positively correlated with speech fluency. CONCLUSIONS Together, these results suggest that gestures are unlikely to have a role in compensating for linguistic deficits and to serve as a representational system conveying thought content independent of language. Surprisingly, aphasia rather is a model of how gesture and language are inherently integrated and aligned: Even when language is impaired, it remains the essential provider of content.

Abstract
Aphasia is an impairment of language caused by acquired brain damage such as stroke or traumatic brain injury, that affects a person’s ability to communicate effectively. The aim of rehabilitation in aphasia is to improve everyday communication, improving an individual’s ability to function in their day-to-day life. For that reason, a thorough understanding of naturalistic communication and its underlying mechanisms is imperative. The field of aphasiology currently lacks an agreed, comprehensive, theoretically founded definition of communication. Instead, multiple disparate interpretations of functional communication are used. We argue that this makes it nearly impossible to validly and reliably assess a person’s communicative performance, to target this behaviour through therapy, and to measure improvements post-therapy. In this article we propose a structured, theoretical approach to defining the concept of functional communication. We argue for a view of communication as “situated language use”, borrowed from empirical psycholinguistic studies with non-brain damaged adults. This framework defines language use as: (1) interactive, (2) multimodal, and (3) contextual. Existing research on each component of the framework from non-brain damaged adults and people with aphasia is reviewed. The consequences of adopting this approach to assessment and therapy for aphasia rehabilitation are discussed. The aim of this article is to encourage a more systematic, comprehensive approach to the study and treatment of situated language use in aphasia.

Abstract
One of the most debilitating symptoms of advanced Parkinson's disease is drooling. Currently, the main treatment that is offered for drooling is botulinum toxin injections to the saliva glands which have a number of side effects and do not treat the causes of drooling, such as impaired swallowing and lip closure. This study explored the effect of an alternative therapy approach for drooling that aimed at improving the swallow, expiratory muscle strength training (EMST). Sixteen participants received EMST over a 6- to 8-week period. Measurements were taken pre- and post-training for drooling (Sialorrhea Clinical Scale for Parkinson's Disease; SCS-PD), swallowing, lip strength and peak cough flow. Measures of drooling, swallowing and peak cough flow were stable over pre-training assessments and improved following training (p < 0.01). The most conservative estimate of the within-group change for SCS-PD was - 2.50 (95% confidence interval - 3.22 to - 1.22). No adverse effects were reported and participants gave high satisfaction ratings for the training. A programme of EMST offers promise as a therapy to reduce drooling for people with Parkinson's disease. Adequately powered randomised controlled trials of EMST are now needed.

Abstract
Purpose The purpose of this study was to investigate the effectiveness of verbal-gestural treatment on verb production in patients with acute aphasia. Method Treatment was delivered during inpatient stay to four participants using a single-subject design. Results All patients demonstrated improvements in verbal expression. Some patients' improvements generalized to untrained verbs and nouns. Conclusions This study indicates verbal-gestural treatment can be an effective treatment model for acute aphasia in a hospital environment. Concurrent deficits resulting from stroke may impact the success with verbal-gestural treatment at this acute phase of recovery.

Caute A, Dipper L, Roper A. The City Gesture Checklist: The development of a novel gesture assessment. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2021; 56:20-35. [PMID: 33051977 DOI: 10.1111/1460-6984.12579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 09/02/2020] [Accepted: 09/08/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND People with aphasia rely on gesture more than healthy controls to get their message across, but use a limited range of gesture types. Gesture therapy is thus a potential avenue of intervention for people with aphasia. However, currently no gesture assessment evaluates how they use gesture. Such a tool could inform therapy targets and measure outcomes. In gesture research, many different coding categories are used to describe gesture forms and functions. These coding methods are prohibitively time-consuming to use in clinical practice. There is therefore a need for a 'quick and dirty' method of assessing gesture use. AIMS To investigate current practice among UK-based clinicians (speech and language therapists) in relation to gesture assessment and therapy, to synthesize gesture-coding frameworks used in aphasia research, to develop a gesture checklist based on the synthesized coding frameworks suitable for use in clinical practice, and to investigate the interrater reliability (IRR) of the checklist among experienced and unfamiliar users. METHODS & PROCEDURES The research team synthesized seven gesture-coding frameworks and trialled three resulting prototype checklists at a co-design workshop with 20 clinicians. Attending clinicians were also consulted about their current clinical gesture practice using a questionnaire. A final City Gesture Checklist (CGC) was developed based upon outcomes and feedback from the workshop. The IRR of the CGC was evaluated between the research team and 11 further clinicians within a second workshop. Both groups used the CGC to count gestures in video clips of people with aphasia talking to a conversation partner. MAIN CONTRIBUTION A total of 18 workshop attendees completed the current practice questionnaire. Of these, 10 reported assessing gesture informally and five also used formal assessment. Gesture-coding synthesis highlighted six main categories of gesture form. Clinicians at the co-design workshop provided feedback on prototype checklists regarding the relevance and usability of the gesture categories, layout, use of images and instructions. A final version of the CGC was created incorporating their recommendations. The IRR for the CGC was moderate between both the researchers and clinicians. CONCLUSIONS & IMPLICATIONS The CGC can be used to assess the types of gesture that people with aphasia produce. The IRR was moderate amongst both experienced users and new users who had received no training. Future research directions include investigating how to improve IRR, evaluating intra-rater reliability and sensitivity to change, and exploring use of the CGC in clinical practice. What this paper adds What is already known on the subject People with aphasia rely on gesture more than healthy speakers, yet use a more limited range of gesture types. Gesture therapy is used by clinicians with the aim of helping people with aphasia to compensate for their language impairment and/or to facilitate speech. What this paper adds to existing knowledge This study explores current gesture assessment practice among UK-based clinicians and synthesizes the coding categories used in the literature about gesture research in aphasia. It describes the development of a novel outcome measure, the CGC, and preliminary testing of its IRR. What are the potential or actual clinical implications of this work? This 'quick and dirty' tool enables clinicians to analyse and record the types of gesture produced by people with aphasia without the need for gesture coding. Preliminary findings suggest that clinicians can use it with a fair degree of reliability by following the checklist's written instructions.

Abstract
It has been suggested that gesture can play a role in the treatment of naming impairments in aphasia, however investigation is still sparse, especially when compared to research on verbal treatments. Critically, previous studies have included either verbal or gesture production in the training. However, while in speakers without language impairment, action naming is facilitated by gesture observation, no study has yet systematically determined whether gesture observation alone influences word retrieval in people with aphasia. This is the aim of the research presented here. In a gesture priming experiment, participants with aphasia named actions that were preceded by the observation of videos of congruent or unrelated gestures or a non-gesture control condition. At the group-level, action naming was facilitated by observation of congruent gestures. However, single-case analyses revealed variability in the extent to which the participants benefited from gesture cueing. The potential mechanisms underlying the effects of gesture observation on action picture naming in people with aphasia were examined by exploring participant-related and item-related predictors of improvement. It is concluded that gesture observation may facilitate verb retrieval at either semantic or lexical levels. In addition, and despite variability across individuals, gesture observation seems more likely to facilitate action naming in people with spared gesture semantics and mild-moderate deficits in lexical-semantic or post-semantic processing.

Abstract
PURPOSE Visuographic supports in the form of images are utilized during assessment and treatment for individuals with aphasia to supplement speech, language, and cognitive losses limiting communication. Clinicians rely on prior experience and intuition to make decisions regarding image-based support design and selection (e.g., augmentative and alternative communication strategies). Researchers have begun to focus on the relationship between the images and the benefits they provide for adults with aphasia. METHOD The aim of this review-resulting from a roundtable discussion at the 2016 Clinical Aphasiology Conference-was to disseminate summaries of current and past researches regarding image use by individuals with aphasia and to highlight areas of need within research and practice. RESULTS Review of the literature illuminated 4 major themes: (a) image creation, capture, and sharing; (b) image characteristics; (c) image use across linguistic domains and contexts; and (d) implications for clinical and research practices. CONCLUSIONS Reviewing current knowledge and practice regarding the use of visual supports for individuals with aphasia is essential to advancing therapeutic practices and providing evidence-based protocols for creating, selecting, and implementing images within augmentative and alternative communication strategies. Several gaps in knowledge were identified as future research needs (e.g., caregiver training and enhanced image feature investigation).

Abstract
Pantomime, gesture in absence of speech, has no conventional meaning. Nevertheless, individuals seem to be able to produce pantomimes and derive meaning from pantomimes. A number of studies has addressed the use of co-speech gesture, but little is known on pantomime. Therefore, the question of how people construct and understand pantomimes arises in gesture research. To determine how people use pantomimes, we asked participants to depict a set of objects using pantomimes only. We annotated what representation techniques people produced. Furthermore, using judgment tasks, we assessed the pantomimes' comprehensibility. Analyses showed that similar techniques were used to depict objects across individuals. Objects with a default depiction method were better comprehended than objects for which there was no such default. More specifically, tools and objects depicted using a handling technique were better understood. The open-answer experiment showed low interpretation accuracy. Conversely, the forced-choice experiment showed ceiling effects. These results suggest that across individuals, similar strategies are deployed to produce pantomime, with the handling technique as the apparent preference. This might indicate that the production of pantomimes is based on mental representations which are intrinsically similar. Furthermore, pantomime conveys semantically rich, but ambiguous, information, and its interpretation is much dependent on context. This pantomime database is available online: https://dataverse.nl/dataset.xhtml?persistentId=hdl:10411/QZHO6M. This can be used as a baseline with which we can compare clinical groups.

Abstract
BACKGROUND Human communication occurs through both verbal and visual/motoric modalities. Simultaneous conversational speech and gesture occurs across all cultures and age groups. When verbal communication is compromised, more of the communicative load can be transferred to the gesture modality. Although people with aphasia produce meaning-laden gestures, the communicative value of these has not been adequately investigated. AIMS To investigate the communicative effectiveness of pantomime gesture produced spontaneously by individuals with aphasia during conversational discourse. METHODS & PROCEDURES Sixty-seven undergraduate students wrote down the messages conveyed by 11 people with aphasia that produced pantomime while engaged in conversational discourse. Students were presented with a speech-only, a gesture-only and a combined speech and gesture condition and guessed messages in both a free description and a multiple-choice task. OUTCOMES & RESULTS As hypothesized, listener comprehension was more accurate in the combined pantomime gesture and speech condition as compared with the gesture- or speech-only conditions. Participants achieved greater accuracy in the multiple-choice task as compared with the free-description task, but only in the gesture-only condition. The communicative effectiveness of the pantomime gestures increased as the fluency of the participants with aphasia decreased. CONCLUSIONS & IMPLICATIONS These results indicate that when pantomime gesture was presented with aphasic speech, the combination had strong communicative effectiveness. Future studies could investigate how pantomimes can be integrated into interventions for people with aphasia, particularly emphasizing elicitation of pantomimes in as natural a context as possible and highlighting the opportunity for efficient message repair.

Abstract
Gestures have a central role in speaking and thinking about spatial information. The goal of the present study is to examine the function of gestures in Williams Syndrome (WS), a genetic disorder characterized by spatial impairments and a preservation of communication. The study's subjects were 11 WS individuals and 22 typically-developing controls who performed a narrative task. We analyzed offline gesture production and its relation with language and spatial information. Compared to the control groups, WS individuals produced more representational gestures that anticipated, supplemented, or gesture-only communication. Gestures produced by WS participants serve a compensatory role particularly in representing spatial contents.

Abstract
Aphasia intervention has made increasing use of technology in recent years. The evidence base, which is largely limited to the investigation of spoken language outcomes, indicates positive treatment effects for people with mild to moderate levels of aphasia. Outcomes for those with severe aphasia, however, are less well documented and – where reported – present less consistent gains for measures of spoken output. This study investigates the effects of a purpose-built gesture therapy technology for people with severe aphasia: GeST+. Study outcomes show significant improvement in gesture production abilities for adults with severe aphasia following computer intervention. They indicate no transfer of effects into naming gains or interactive gesture. Outcomes offer encouraging results for computer therapy methods within this hitherto under-researched population but indicate a need for further refinement of interventions in order to maximize persistence of effects and generalization into everyday communication.

Abstract
PURPOSE The present article aimed to inform clinical practice on whether people with aphasia (PWA) deploy pantomime techniques similarly to participants without brain damage (PWBD) and if not, what factors influence these differences. METHOD We compared 38 PWA to 20 PWBD in their use of 6 representation techniques (handling, enact, object, shape, deictic, and other) when pantomiming objects, and determined whether PWA used the same defaults as PWBD. We assessed the influence of (non-)dominant arm use, ideomotor apraxia, semantic processing, aphasia severity, and oral naming. RESULTS PWA used various pantomime techniques. Enact, deictic, and other were used infrequently. No differences were found for the use of shape techniques, but PWA used fewer handling and object techniques than PWBD and they did not use these for the same objects as PWBD did. No influence was found for (non-)dominant arm use. All other variables correlated with the use of handling, object, and defaults. CONCLUSION In our study, PWA were able to use various pantomime techniques. As a group, they used these techniques differently from PWBD and relied more heavily on the use of shape techniques. This was not influenced by a hemiparesis, but seemed dependent on semantic processing. Clinical implications are discussed.

Abstract
BACKGROUND Individuals with aphasia often receive therapy from a speech-language pathologist during acute rehabilitation. The literature demonstrates that group-based therapy provides a natural, social environment for language rehabilitation in mild-moderate and/or chronic aphasia; however, the communication of persons with acute, severe non-fluent aphasia during group treatment has not been fully explored. OBJECTIVE This observational study investigated patient communication during acute rehabilitation. The primary objective was to determine whether participants initiate more communication during group therapy sessions when compared to individual therapy sessions. METHOD Ten participants with severe non-fluent aphasia were observed during one individual and one group session during their stay in an acute, inpatient rehabilitation facility. Communicative initiations were tallied and categorized based on type, target, and purpose. RESULTS Participants initiated communication more often during group sessions than during individual sessions. During groups, participants used more vocalizations and facial expressions to communicate, and the purpose was more often for social closeness than in individual sessions. Participants produced fewer different, real words in group vs. individual sessions, but other measures of communication skill did not differ significantly between the two settings. CONCLUSION In the aphasia group treatment described in this study, participants initiated more communication, with greater diversity of expressive modalities and more varied communicative purposes. Participants in group therapy also showed an increased tendency to communicate for the purpose of social closeness. These findings suggest that there are important differences in the communication of patients participating in group vs. individual speech therapy for treatment of acute, severe non-fluent aphasia.

Abstract
People often use spontaneous gestures when communicating spatial information. We investigated focal brain-injured individuals to test the hypotheses that (1) naming motion event components of manner-path (represented by verbs-prepositions in English) are impaired selectively, (2) gestures compensate for impaired naming. Patients with left or right hemisphere damage (LHD or RHD) and elderly control participants were asked to describe motion events (e.g., running across) depicted in brief videos. Damage to the left posterior middle frontal gyrus, left inferior frontal gyrus, and left anterior superior temporal gyrus (aSTG) produced impairments in naming paths of motion; lesions to the left caudate and adjacent white matter produced impairments in naming manners of motion. While the frequency of spontaneous gestures were low, lesions to the left aSTG significantly correlated with greater production of path gestures. These suggest that producing prepositions-verbs can be separately impaired and gesture production compensates for naming impairments when damage involves left aSTG.

Perception of co-speech gestures in aphasic patients: a visual exploration study during the observation of dyadic conversations. Cortex 2014; 64:157-68. [PMID: 25461716 DOI: 10.1016/j.cortex.2014.10.013] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2014] [Revised: 07/07/2014] [Accepted: 10/20/2014] [Indexed: 01/09/2023]
Abstract
BACKGROUND Co-speech gestures are part of nonverbal communication during conversations. They either support the verbal message or provide the interlocutor with additional information. Furthermore, they prompt as nonverbal cues the cooperative process of turn taking. In the present study, we investigated the influence of co-speech gestures on the perception of dyadic dialogue in aphasic patients. In particular, we analysed the impact of co-speech gestures on gaze direction (towards speaker or listener) and fixation of body parts. We hypothesized that aphasic patients, who are restricted in verbal comprehension, adapt their visual exploration strategies. METHODS Sixteen aphasic patients and 23 healthy control subjects participated in the study. Visual exploration behaviour was measured by means of a contact-free infrared eye-tracker while subjects were watching videos depicting spontaneous dialogues between two individuals. Cumulative fixation duration and mean fixation duration were calculated for the factors co-speech gesture (present and absent), gaze direction (to the speaker or to the listener), and region of interest (ROI), including hands, face, and body. RESULTS Both aphasic patients and healthy controls mainly fixated the speaker's face. We found a significant co-speech gesture × ROI interaction, indicating that the presence of a co-speech gesture encouraged subjects to look at the speaker. Further, there was a significant gaze direction × ROI × group interaction revealing that aphasic patients showed reduced cumulative fixation duration on the speaker's face compared to healthy controls. CONCLUSION Co-speech gestures guide the observer's attention towards the speaker, the source of semantic input. It is discussed whether an underlying semantic processing deficit or a deficit to integrate audio-visual information may cause aphasic patients to explore less the speaker's face.

Abstract
PURPOSE For many individuals with aphasia, gestures form a vital component of message transfer and are the target of speech-language pathology intervention. What remains unclear are the participant variables that predict successful outcomes from gesture treatments. The authors examined the gesture production of a large number of individuals with aphasia-in a consistent discourse sampling condition and with a detailed gesture coding system-to determine patterns of gesture production associated with specific types of aphasia. METHOD The authors analyzed story retell samples from AphasiaBank (TalkBank, n.d.), gathered from 98 individuals with aphasia resulting from stroke and 64 typical controls. Twelve gesture types were coded. Descriptive statistics were used to describe the patterns of gesture production. Possible significant differences in production patterns according to aphasia type were examined using a series of chi-square, Fisher exact, and logistic regression statistics. RESULTS A significantly higher proportion of individuals with aphasia gestured as compared to typical controls, and for many individuals with aphasia, this gesture was iconic and was capable of communicative load. Aphasia type impacted significantly on gesture type in specific identified patterns, detailed here. CONCLUSION These type-specific patterns suggest the opportunity for gestures as targets of aphasia therapy.

Abstract
Gestures accompany speech and enrich human communication. When aphasia interferes with verbal abilities, gestures become even more relevant, compensating for and/or facilitating verbal communication. However, small-scale clinical studies yielded diverging results with regard to a therapeutic gesture benefit for lexical retrieval. Based on recent functional neuroimaging results, delineating a speech-gesture integration network for lexical learning in healthy adults, we hypothesized that the commonly observed variability may stem from differential patholinguistic profiles in turn depending on lesion pattern. Therefore we used a controlled novel word learning paradigm to probe the impact of gestures on lexical learning, in the lesioned language network. Fourteen patients with chronic left hemispheric lesions and mild residual aphasia learned 30 novel words for manipulable objects over four days. Half of the words were trained with gestures while the other half were trained purely verbally. For the gesture condition, rootwords were visually presented (e.g., Klavier, [piano]), followed by videos of the corresponding gestures and the auditory presentation of the novel words (e.g., /krulo/). Participants had to repeat pseudowords and simultaneously reproduce gestures. In the verbal condition no gesture-video was shown and participants only repeated pseudowords orally. Correlational analyses confirmed that gesture benefit depends on the patholinguistic profile: lesser lexico-semantic impairment correlated with better gesture-enhanced learning. Conversely largely preserved segmental-phonological capabilities correlated with better purely verbal learning. Moreover, structural MRI-analysis disclosed differential lesion patterns, most interestingly suggesting that integrity of the left anterior temporal pole predicted gesture benefit. Thus largely preserved semantic capabilities and relative integrity of a semantic integration network are prerequisites for successful use of the multimodal learning strategy, in which gestures may cause a deeper semantic rooting of the novel word-form. The results tap into theoretical accounts of gestures in lexical learning and suggest an explanation for the diverging effect in therapeutical studies advocating gestures in aphasia rehabilitation.

Abstract
PURPOSE There is a 40-year history of interest in the use of arm and hand gestures in treatments that target the reduction of aphasic linguistic impairment and compensatory methods of communication (Rose, 2006). Arguments for constraining aphasia treatment to the verbal modality have arisen from proponents of constraint-induced aphasia therapy (Pulvermüller et al., 2001). Confusion exists concerning the role of nonverbal treatments in treating people with aphasia. The central argument of this paper is that given the state of the empirical evidence and the strong theoretical accounts of modality interactions in human communication, gesture-based and multimodality aphasia treatments are at least as legitimate an option as constraint-based aphasia treatment. METHOD Theoretical accounts of modality interactions in human communication and the gesture production abilities of individuals with aphasia that are harnessed in treatments are reviewed. The negative effects on word retrieval of restricting gesture production are also reviewed, and an overview of the neurological architecture subserving language processing is provided as rationale for multimodality treatments. The evidence for constrained and unconstrained treatments is critically reviewed. CONCLUSION Together, these data suggest that constraint treatments and multimodality treatments are equally efficacious, and there is limited support for constraining client responses to the spoken modality.

Abstract
PURPOSE In this study, the authors investigated whether gesture, naming, and strategic treatment improved the communication skills of 14 people with severe aphasia. METHOD All participants received 15 hr of gesture and naming treatment (reported in a companion article [Marshall et al., 2012]). Half the group received a further 15 hr of strategic therapy, whereas the remaining 7 participants received no further input. The effects of therapy on communication were assessed with 2 novel measures. These measures required each participant to convey simple messages and narratives to his or her communication partner. In both assessments, a subset of the stimuli featured items that had been targets in gesture or naming treatment. RESULTS Performance on the communication measures was stable over 2 baseline assessments but improved after gesture and naming treatment. Those participants who received additional strategic therapy made further gains on the message but not on the narrative task. Communication gains were not specific to the stimuli featuring trained items. CONCLUSIONS This study suggests that gesture and naming treatments can benefit interactive communication. The additional benefits of strategic therapy were less clear-cut but did have an impact on the transmission of simple messages. Gains seem to reflect the development of general communication skills rather than the use of trained gestures and/or words.
