Abstract
Persons with severe non-fluent aphasia would benefit from using gestures to substitute for their absent powers of speech. The use of gestures, however, is challenging for persons with aphasia and concomitant limb apraxia. Research on the long-term recovery of gestures is scant, and it is unclear whether gesture performance can show recovery over time. This study evaluated the recovery of emblems and tool use pantomimes of persons with severe non-fluent aphasia and limb apraxia after a left hemisphere stroke. The Florida Apraxia Screening Test-Revised (FAST-R) was used for measurements. The test includes 30 gestures to be performed (i) after an oral request, (ii) with the aid of a pictorial cue, or (iii) as an imitation. The gestures were rated on their degree of comprehensibility. The comprehensibility of gestures after an oral request improved significantly in five out of seven participants between the first (1-3 months after the stroke) and the last (3 years after) examination. Improvement continued for all five in the period between six months and three years. The imitation model did improve the comprehensibility of gestures for all participants, whereas the pictorial cue did so just slightly. The skill of producing gestures can improve even in the late phase post-stroke. Because of this potential, we suggest that gesture training should be systematically included in the rehabilitation of communication for persons with severe non-fluent aphasia.

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.

INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2022; 57:403-421. [PMID: 34967962 DOI: 10.1111/1460-6984.12691] [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: 12/30/2020] [Revised: 11/15/2021] [Accepted: 11/18/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Unaided communication behaviours may provide communication support for persons with severe cerebrovascular accidents (CVA), as these individuals often experience severe communication difficulties, regardless of the aetiology. Though often subtle, these behaviours are present during all stages of recovery, and therefore communication partners need to know not only which unaided strategies are used as communication attempts, but also what their function is (i.e., what the person aims to achieve with the communication). AIM To identify the unaided communication behaviours that adults with severe CVA and little or no functional speech use to communicate, and to determine the communication functions addressed by these behaviours. METHODS & PROCEDURES The study used a scoping review methodology and included articles on communication partners of persons with CVA published between 1986 and 2020. Initially the searches yielded 732 studies from which 211 duplicates were identified. The remaining studies (n = 531) were then screened on title, abstract and full-text level resulting in a final inclusion of 18 studies. Of the 18 studies, five were qualitative and 13 consisted of quantitative methodologies. MAIN CONTRIBUTION The subtle communication behaviours used by persons with CVA (and resultant severe communication difficulties) are often misinterpreted or overlooked by their partners. If partners are trained to recognise such subtle or unaided communication behaviours, they can provide adequate support to access a range of communication functions. The unaided communication behaviours, which include 13 primary behaviours ranging from non-linguistic to linguistic, were utilised to convey 31 communication functions classified into four main communication categories. CONCLUSIONS & IMPLICATIONS Although unaided communication behaviours often appear as limiting, they can be utilised to communicate various communication functions. The findings of this review support the training of partners to identify these behaviours and improve person-partner communication. WHAT IS KNOWN?: Unaided communication has been widely researched. However, a summary is needed of the various unaided communication behaviours and of the different communication functions addressed by these behaviours. What the paper adds… This paper emphasises that unaided communication behaviours range from non-linguistic to linguistic, and they can support unintentional, pre-intentional and intentional communication functions. Clinical implications Even though aided communication is preferred, unaided communication behaviours are generally used in contexts with limited resources, as well as among culturally and linguistically diverse populations. This study advocates the identification of unaided communication behaviours by partners as well as the support and provision of access to communication strategies for persons with severe CVA. Future research should include more untrained communication partners.

Abstract
PURPOSE In persons living with aphasia, we will explore the relationship between iconic gesture production during spontaneous speech and discourse task, spoken language, and demographic information. METHOD Employing the AphasiaBank database, we coded iconic gestures in 75 speakers with aphasia during two spoken discourse tasks: a procedural narrative, which involved participants telling the experimenter how to make a sandwich ("Sandwich"), and a picture sequence narrative, which had participants describe the picture sequence to the experimenter ("Window"). Forty-three produced a gesture during both tasks, and we further evaluate data from this subgroup as a more direct comparison between tasks. RESULTS More iconic gestures, at a higher rate, were produced during the procedural narrative. For both tasks, there was a relationship between iconic gesture rate, modeled as iconic gestures per word, and metrics of language dysfluency extracted from the discourse task as well as a metric of fluency extracted from a standardized battery. Iconic gesture production was correlated with aphasia duration, which was driven by performance during only a single task (Window), but not with other demographic metrics, such as aphasia severity or age. We also provide preliminary evidence for task differences shown through the lens of two types of iconic gestures. CONCLUSIONS While speech-language pathologists have utilized gesture in therapy for poststroke aphasia, due to its possible facilitatory role in spoken language, there has been considerably less work in understanding how gesture differs across naturalistic tasks and how we can best utilize this information to better assess gesture in aphasia and improve multimodal treatment for aphasia. Furthermore, our results contribute to gesture theory, particularly, about the role of gesture across naturalistic tasks and its relationship with spoken language.

Abstract
Purpose When we speak, we gesture, and indeed, persons with aphasia gesture more frequently. The reason(s) for this is still being investigated, spurring an increase in the number of studies of gesture in persons with aphasia. As the number of studies increases, so too does the need for a shared set of best practices for gesture research in aphasia. After briefly reviewing the importance and use of gesture in persons with aphasia, this viewpoint puts forth methodological and design considerations when evaluating gesture in persons with aphasia. Method & Results We explore several different design and methodological considerations for gesture research specific to persons with aphasia, such as video angle specifications, data collection techniques, and analysis considerations. The goal of these suggestions is to develop transparent and reproducible methods for evaluating gesture in aphasia to build a solid foundation for continued work in this area. Conclusions We have proposed that it is critical to evaluate multimodal communication in a methodologically robust way to facilitate increased knowledge about the relationship of gesture to spoken language, cognition, and to other aspects of living with aphasia and recovery from aphasia. We conclude by postulating future directions for gesture research in aphasia.

Abstract
Limb apraxia is evident in approximately 50% of patients after left hemisphere cerebral vascular accident (LCVA) and increases disability and caregiver dependence. Individuals with apraxia exhibit abnormalities in spatio-temporal aspects of gesture production and/or in knowledge of tool-related actions (action semantics). This preliminary study of three LCVA participants aimed to (i) explore the efficacy of a novel Action Network Treatment (ANT) that focused on improving the semantic association between tool actions and other types of tool knowledge, an intervention inspired by successful semantic network treatments in aphasia (e.g., Edmonds et al., 2009), and (ii) explore whether there are individuals with apraxia who benefit from ANT relative to a version of a comparatively well-studied existing apraxia treatment (Smania et al., 2006; Smania et al., 2000) that shapes gesture via focus on practicing the spatio-temporal aspects of gesture production (Tool Use Treatment or TUT). One participant demonstrated treatment benefits from both ANT and TUT, while another only benefited from TUT. These findings indicate that our novel semantic network strengthening approach to gesture training may be efficacious in at least some individuals with apraxia, and provide a foundation for future study of the characteristics of people with apraxia who benefit from each approach.

Abstract
Apraxia is widely used to describe one of the more disabling deficits following left strokes. The role of rehabilitation in treating apraxic stroke patients remains unclear. This systematic review was conducted to study the impacts of various rehabilitation interventions on the limb apraxia post-stroke. PubMed, SCOPUS, PEDro, CINAHL, MEDLINE, REHABDATA, and Web of Science were searched for the experimental studies that investigated the effects of the rehabilitation interventions on apraxia in patients with stroke. The methodological quality was rated using the Physiotherapy Evidence Database scale (PEDro). Six studies met our inclusion criteria in this systematic review. Four were randomized controlled trials, pilot (n = 1), and case study (n = 1). The scores on the PEDro scale ranged from two to eight, with a median of seven. The results showed some evidence for the effects of strategy training and gesture training interventions on the cognitive functions, motor activities, and activities of daily livings outcomes poststroke. The preliminary findings showed that the effects of the strategy training and the gesture training on apraxia in patients with stroke are promising. Further randomized controlled trials with long-term follow-ups are strongly needed.

Abstract
Neurorehabilitation and brain stimulation studies of post-stroke patients suggest that action-observation effects can lead to rapid improvements in the recovery of motor functions and long-term motor cortical reorganization. Apraxia is a clinically important disorder characterized by marked impairment in representing and performing skillful movements [gestures], which limits many daily activities and impedes independent functioning. Recent clinical research has revealed errors of visuo-motor integration in patients with apraxia. This paper presents a rehabilitative perspective focusing on the possibility of action observation as a therapeutic treatment for patients with apraxia. This perspective also outlines impacts on neurorehabilitation and brain repair following the reinforcement of the perceptual-motor coupling. To date, interventions based primarily on action observation in apraxia have not been undertaken.

Abstract
BACKGROUND This study explores the psychometric properties of The Scenario Test UK, a culturally adapted version of the Dutch original (The Scenario Test) developed by van der Meulen et al. in 2010, which evaluates functional, daily-life communication in aphasia. The Scenario Test assesses communication in an interactive context with a supportive communication partner. AIMS To evaluate the reliability (internal consistency, interrater and test-retest reliability) and construct validity (convergent, discriminant and known-groups validity) of The Scenario Test UK. METHODS & PROCEDURES The Scenario Test UK and other language, cognition and praxis assessments were administered to persons with aphasia after stroke (3+ months post-stroke) and to non-aphasic controls. Participants were recruited primarily through community stroke groups. Measures were completed in an interview format. Standard psychometric criteria were used to evaluate reliability and construct validity. OUTCOMES & RESULTS A total of 74 participants with aphasia and 20 participants without aphasia took part in The Scenario Test UK. The test showed high levels of reliability. Internal consistency (Cronbach's α = 0.92), interrater reliability (ICC = 0.95) and test-retest reliability (ICC = 0.96) were excellent. Interrater agreement in scores on the individual items ranged from good to excellent (κ = 0.41-1.00) for all but two items (item 4c κ = 0.38, item 6c κ = 0.36). The test demonstrated good levels of convergent (ρ = 0.37-0.75) and discriminant validity (ρ = -0.04 to 0.23). There was strong evidence for known groups validity (U = 132.50, p < .001), with those with aphasia scoring significantly lower [median (interquartile range-IQR) = 47 (39.8-51.0)] than those without aphasia [53 (52-54)]. CONCLUSIONS & IMPLICATIONS The data support the reliability and validity of the Scenario Test UK as an assessment of functional, daily-life communication for persons with aphasia. Further testing is needed in independent samples on the measure's psychometric properties, including its sensitivity to change. Pending this testing, The test can be used as an assessment tool to evaluate communication skills with people with aphasia, to guide goal setting for therapy and to measure outcomes in response to therapy.

Abstract
Communicative gestures can compensate incomprehensibility of oral speech in severe aphasia, but the brain damage that causes aphasia may also have an impact on the production of gestures. We compared the comprehensibility of gestural communication of persons with severe aphasia and non-aphasic persons and used voxel based lesion symptom mapping (VLSM) to determine lesion sites that are responsible for poor gestural expression in aphasia. On group level, persons with aphasia conveyed more information via gestures than controls indicating a compensatory use of gestures in persons with severe aphasia. However, individual analysis showed a broad range of gestural comprehensibility. VLSM suggested that poor gestural expression was associated with lesions in anterior temporal and inferior frontal regions. We hypothesize that likely functional correlates of these localizations are selection of and flexible changes between communication channels as well as between different types of gestures and between features of actions and objects that are expressed by gestures.

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
Autism is a developmental disability characterized by atypical social interaction, interests or body movements, and communication. Our review examines the empirical status of three communication phenomena believed to be unique to autism: pronoun reversal (using the pronoun you when the pronoun I is intended, and vice versa), echolalia (repeating what someone has said), and a reduced or even reversed production-comprehension lag (a reduction or reversal of the well-established finding that speakers produce less sophisticated language than they can comprehend). Each of these three phenomena has been claimed to be unique to autism; therefore, each has been proposed to be diagnostic of autism, and each has been interpreted in autism-centric ways (psychoanalytic interpretations of pronoun reversal, behaviorist interpretations of echolalia, and clinical lore about the production-comprehension lag). However, as our review demonstrates, none of these three phenomena is in fact unique to autism; none can or should serve as diagnostic of autism, and all call into question unwarranted assumptions about autistic persons and their language development and use.

Abstract
Background Upper limb apraxia is a common disorder associated with stroke that can reduce patients’ independence levels in activities of daily living and increase levels of disability. Traditional rehabilitation programs designed to promote the recovery of upper limb function have mainly focused on restorative or compensatory approaches. However, no previous studies have been completed that evaluate a combined intervention method approach, where patients concurrently receive cognitive training and learn compensatory strategies for enhancing daily living activities. Methods/Design This study will use a two-arm, assessor-blinded, parallel, randomized controlled trial design, involving 40 patients who present a left- or right-sided unilateral vascular lesion poststroke and a clinical diagnosis of upper limb apraxia. Participants will be randomized to either a combined functional rehabilitation or a traditional health education group. The experimental group will receive an 8-week combined functional program at home, including physical and occupational therapy focused on restorative and compensatory techniques for upper limb apraxia, 3 days per week in 30-min intervention periods. The control group will receive a conventional health education program once a month over 8 weeks, based on improving awareness of physical and functional limitations and facilitating the adaptation of patients to the home. Study outcomes will be assessed immediately postintervention and at the 2-month follow-up. The primary outcome measure will be basic activities of daily living skills as assessed with the Barthel Index. Secondary outcome measures will include the following: 1) the Lawton and Brody Instrumental Activities of Daily Living Scale, 2) the Observation and Scoring of ADL-Activities, 3) the De Renzi Test for Ideational Apraxia, 4) the De Renzi Test for Ideomotor Apraxia, 5) Recognition of Gestures, 6) the Test of Upper Limb Apraxia (TULIA), and 7) the Quality of Life Scale For Stroke (ECVI-38). Discussion This trial is expected to clarify the effectiveness of a combined functional rehabilitation approach compared to a conservative intervention for improving upper limb movement and function in poststroke patients. Trial registration Clinical Trial Gov number NCT02199093. The protocol registration was received 23 July 2014. Participant enrollment began on 1 May 2014. The trial is expected to be completed in March 2016.

Abstract
BACKGROUND Gesticulation (gestures accompanying speech) and pantomime (gestures in the absence of speech) can each be comprehensible. Little is known about the differences between these two gesture modes in people with aphasia. AIMS To discover whether there are differences in the communicative use of gesticulation and pantomime in QH, a person with severe fluent aphasia. METHODS & PROCEDURES QH performed two tasks: naming objects and retelling a story. He did this once in a verbal condition (enabling gesticulation) and once in a pantomime condition. For both conditions, the comprehensibility of gestures was analysed in a forced-choice task by naïve judges. Secondly, a comparison was made between QH and healthy controls for the representation techniques used. OUTCOMES & RESULTS Pantomimes produced by QH for naming objects were significantly more comprehensible than chance, whereas his gesticulation was not. For retelling a story the opposite pattern was found. When naming objects QH gesticulated much more than did healthy controls. His pantomimes for this task were simpler than those used by the control group. For retelling a story no differences were found. CONCLUSIONS & IMPLICATIONS Although QH did not make full use of each gesture modes' potential, both did contribute to QH's comprehensibility. Crucially, the benefits of each mode differed across tasks. This implies that both gesture modes should be taken into account separately in models of speech and gesture production and in clinical practice for different communicative settings.

Abstract
Some people with cerebral palsy have motor and associated impairments that may hinder verbal and gestural expression to various extents. This study explores whether the ability to produce verbal or gestural expressions may be related to the comprehension of verbal communications and gestures. The influence of severity of motor impairment, general cognitive performance, and age on comprehension ability was also explored. Forty people with cerebral palsy were assigned to different groups according to their verbal and gestural expression abilities. A neuropsychological assessment of comprehension abilities and general cognitive performance was carried out. Multiple linear regression analysis was applied to identify the possible influence of expression abilities on comprehension abilities and also to detect the possible contribution of severity of motor impairment, general cognitive performance, and age. Results indicate that verbal and gestural comprehension was mainly predicted by general cognitive performance. Severity of motor impairment and age did not contribute to predicting comprehension abilities. Only verbal grammar comprehension was significantly predicted by verbal expression ability. Verbal expression ability may be an important marker for cerebral palsy therapies. In non-ambulant patients with bilateral cerebral palsy, impaired gestural expression should not be taken as an indicator of impaired gestural comprehension.

Abstract
Although there is a substantive body of research about the language used by individuals with aphasia, relatively little is known about their spontaneous iconic gesture. A single case study of LT, an individual with conduction aphasia indicated qualitative differences between the spontaneous iconic gestures produced alongside fluent speech and in tip of the tongue states. The current study examined the iconic gestures produced by another individual with conduction aphasia, WT, and a group of 11 control participants. Comparisons were made between iconic gestures produced alongside normal language and those produced alongside word-searching behaviour. Participants recounted the Tweety and Sylvester cartoon Canary Row. All gesture produced was analysed qualitatively and quantitatively. WT produced more iconic gestures than controls accompanying word searching behaviour, whereas he produced a similar frequency of iconic gestures to control participants alongside normal language. The iconic gestures produced in the two language contexts also differed qualitatively. Frequency of iconic gesture production was not affected by limb apraxia. This study suggests that there are differences between iconic gestures that are produced alongside normal language and those produced alongside word-searching behaviour. Theoretical and clinical implications of these findings are discussed.

Abstract
PURPOSE To study the independence of gesture and verbal language production. The authors assessed whether gesture can be semantically compensatory in cases of verbal language impairment and whether speakers with aphasia and control participants use similar depiction techniques in gesture. METHOD The informativeness of gesture was assessed in 3 forced-choice studies, in which raters assessed the topic of the speaker's message in video clips of 13 speakers with moderate aphasia and 12 speakers with severe aphasia, who were performing a communication test (the Scenario Test). Both groups were compared and contrasted with 17 control participants, who either were or were not allowed to communicate verbally. In addition, the representation techniques used in gesture were analyzed. RESULTS Gestures produced by speakers with more severe aphasia were less informative than those by speakers with moderate aphasia, yet they were not necessarily uninformative. Speakers with more severe aphasia also tended to use fewer representation techniques (mostly relying on outlining gestures) in co-speech gesture than control participants, who were asked to use gesture instead of speech. It is important to note that limb apraxia may be a mediating factor here. CONCLUSIONS These results suggest that in aphasia, gesture tends to degrade with verbal language. This may imply that the processes underlying verbal language and co-speech gesture production, although partly separate, are closely linked.

Abstract
PURPOSE In this study, the authors (a) investigated whether a group of people with severe aphasia could learn a vocabulary of pantomime gestures through therapy and (b) compared their learning of gestures with their learning of words. The authors also examined whether gesture therapy cued word production and whether naming therapy cued gestures. METHOD Fourteen people with severe aphasia received 15 hr of gesture and naming treatments. Evaluations comprised repeated measures of gesture and word production, comparing treated and untreated items. RESULTS Baseline measures were stable but improved significantly following therapy. Across the group, improvements in naming were greater than improvements in gesture. This trend was evident in most individuals' results, although 3 participants made better progress in gesture. Gains were item specific, and there was no evidence of cross-modality cueing. Items that received gesture therapy did not improve in naming, and items that received naming therapy did not improve in gesture. CONCLUSIONS Results show that people with severe aphasia can respond to gesture and naming therapies. Given the unequal gains, naming may be a more productive therapy target than gesture for many (although not all) individuals with severe aphasia. The communicative benefits of therapy were not examined but are addressed in a follow-up article.

Abstract
Upper limb apraxia, a disorder of higher motor cognition, is a common consequence of left-hemispheric stroke. Contrary to common assumption, apraxic deficits not only manifest themselves during clinical testing but also have delirious effects on the patients' everyday life and rehabilitation. Thus, a reliable diagnosis and efficient treatment of upper limb apraxia is important to improve the patients' prognosis after stroke. Nevertheless, to date, upper limb apraxia is still an underdiagnosed and ill-treated entity. Based on a systematic literature search, this review summarizes the current tools of diagnosis and treatment strategies for upper limb apraxia. It furthermore provides clinicians with graded recommendations. In particular, a short screening test for apraxia, and a more comprehensive diagnostic apraxia test for clinical use are recommended. Although currently only a few randomized controlled studies investigate the efficacy of different apraxia treatments, the gesture training suggested by Smania and colleagues can be recommended for the therapy of apraxia, the effects of which were shown to extend to activities of daily living and to persist for at least 2 months after completion of the training. This review aims at directing the reader's attention to the ecological relevance of apraxia. Moreover, it provides clinicians with appropriate tools for the reliable diagnosis and effective treatment of apraxia. Nevertheless, this review also highlights the need for further research into how to improve diagnosis of apraxia based on neuropsychological models and to develop new therapeutic strategies.

Abstract
OBJECTIVES To assess whether production of communicative gestures can be ameliorated by therapy, to explore factors that might influence individual variability of therapeutic success and to find out whether therapy effects generalize to unpractised gestures. SETTING Hospital department specializing in rehabilitation of patients with neuropsychological disorders. SUBJECTS Twenty-three consecutive severely aphasic patients received therapy; ten were tested repeatedly without interpolated therapy. DESIGN Twenty-four communicative gestures were divided into three sets of eight gestures. In the therapy group one set was practised during each of three consecutive periods and after that period changes in proficiency were assessed for all three sets. Comparisons were made between changes of practised and unpractised gestures during each therapy period within the therapy group, and between changes of unpractised gestures in the therapy group, and the changes brought forward by repeated testing in the control group. INTERVENTIONS Therapy was centred on familiarizing patients with the communicative functions of gestures and on improving the spatial precision of their gestures. MAIN MEASURE Scoring of gestures considered their accuracy and the necessity of assistance. RESULTS Therapy led to substantial improvement of practised gestures. There was also improvement of unpractised gestures which was significantly smaller than that of practised gestures but greater than the improvement induced by repeated testing in the control group. CONCLUSIONS In view of the limited generalization, gesture therapy should concentrate on gestures that are relevant for communication in daily living of the individual patients.

Abstract
A new instrument for the assessment of the different levels of gesture processing, as identified by recent cognitive models of apraxia, is presented. The battery comprises thirteen tasks -- eight assess the production of meaningful gestures both on command and on imitation, four tasks assess the ability to recognize and identify gestures, and one task assesses imitation of meaningless gestures. The battery encompasses a novel test of gesture production on visual command. A total of 60 healthy British volunteers were tested with the entire battery. On the whole, participants made more errors with pantomimes than with other tasks. Their scores served as norms.

Abstract
Apraxic phenomena occur in various neurological conditions. Selective motion control is viewed as the basic capacity to make fine and precise, isolated or independent face or limb movements. Its deficit can indicate limb-kinetic apraxia if it is not explained by paresis, somatosensory deafferentation, or ataxia. The core deficit in ideomotor apraxia could be deficient movement representations, i.e. the combination of invariant features of intrinsic and extrinsic coding for a given movement, which are most important when movements have to be performed outside their typical context. Ideational apraxia would be defined by a semantic deficit related to action. Frontal apraxia is characterised by an action-sequencing deficit. A detailed model is proposed regarding processes relevant to praxis.

Abstract
Apraxias are deficits in higher motor behaviour that are not primarily caused by elementary deficits of the sensorimotor system, communication problems, or dementia. These patients present with deficits such as imitating meaningful or meaningless gestures and in dexterity or purposeful use of objects. The different forms of apraxia originate from lesions of different levels/structures of the motor system, reflecting its complexity. Apraxias are caused by deficits in motor programmes generated in the frontal motor areas, in modality-specific higher sensorimotor control, or at the highest level of motor planning and motor conception. The types of apraxia differentially affect activities of daily living and hence show marked differences in the prognosis of recovery and the physiotherapeutic treatment required. Therefore, appropriate diagnosis and treatment of the different forms are of foremost clinical importance.

Abstract
OBJECTIVES To determine the frequency of manual and oral apraxia in acute stroke and to examine the influence of these symptoms on functional outcome. DESIGN Seven hundred seventy six unselected, acute stroke patients who were admitted within seven days of stroke onset with unimpaired consciousness were included. If possible, the patients were assessed for manual and oral apraxia on acute admission. Neurologic stroke severity including aphasia was assessed with the Scandinavian Stroke Scale, and activities of daily living function was assessed with the Barthel Index. All patients completed their rehabilitation in the same large stroke unit. RESULTS Six hundred eighteen patients could cooperate with the apraxia assessments. Manual apraxia was found in 7% of subjects (10% in left and 4% in right hemispheric stroke; chi2 = 9.0; P = 0.003). Oral apraxia was found in 6% (9% in left and 4% in right hemispheric stroke; chi2 = 5.4; P = 0.02). Both manual and oral apraxia were related to increasing stroke severity, and manual, but not oral, apraxia was associated with increasing age. There was no gender difference in frequency of apraxia. Patients with either type of apraxia had temporal lobe involvement more often than patients without. When analyzed with multiple linear and logistic regression analyses, neither manual nor oral apraxia had any independent influence on functional outcome. CONCLUSION Apraxia is significantly less frequent in unselected patients with acute stroke than has previously been assumed and has no independent negative influence on functional outcome.

Abstract
OBJECTIVE To assess the effectiveness of a rehabilitative training program for patients with limb apraxia. DESIGN Randomized, controlled trial. SETTING Neurologic rehabilitation unit of a university hospital. PATIENTS Thirteen patients with acquired brain injury and limb apraxia (lasting more than 2 months) as a result of lesions involving the left cerebral hemisphere. Patients were assigned to a study group or to a control group following a randomization scheme. The study group underwent an experimental training for limb apraxia. The control group received conventional treatment for aphasia. INTERVENTION A behavioral training program consisting of gesture-production exercises. The rehabilitative program was made up of 3 sections dedicated to the treatment of gestures with or without symbolic value and related or nonrelated to the use of objects. Thirty-five experimental sessions, each lasting 50 minutes, were given. MAIN OUTCOME MEASURES Neuropsychologic tests for assessment of aphasia, verbal comprehension, "general intelligence," oral apraxia, constructional apraxia, and 3 tests concerning limb praxic function (ideational apraxia, ideomotor apraxia, gesture recognition). Scores related to each test were used to measure the outcome. Video recordings of ideational and ideomotor apraxia tests allowed us to register type and number of praxic errors. All outcome measures, except the aphasia test, were recorded before and after the experimental (or control) treatment time interval. RESULTS The patients in the study group achieved a significant improvement of performance in both ideational (p = .039) and ideomotor (p = .043) apraxia tests. They also showed a significant reduction of errors in ideational (p = .001) and ideomotor (p < .001) apraxia tests. A trend toward improvement was found in the gesture comprehension test (p = .058), while other outcome measures did not show any significant amelioration. Control patients did not show any significant change in performance. CONCLUSIONS The results show the possible effectiveness of a specific training program for the treatment of limb apraxia.

Abstract
Because language and praxis each require the activation and selection of knowledge structures in long-term memory (MacKay, 1985, 1987), it is reasonable to consider whether hemisphere asymmetries for such processes span both domains. Language and skilled movement are thought to be strongly lateralized to the left hemisphere in most individuals. Yet, although recent evidence suggests that the right hemisphere also contributes to language use in context, few similar arguments have been made for the right hemisphere's involvement in motor planning. In this paper, we review some of the evidence for a right hemisphere role in language and action processing and propose that within each domain the right hemisphere activates a range of relevant knowledge structures without selection.

Abstract
Neurobehavioral studies of gesturing have been largely limited to left hemisphere damaged (LHD) patients. We compared spontaneous gesturing in seven right hemisphere damaged (RHD) patients, seven LHD patients, and seven normal controls (NHD) during videotaped interviews. Two judges coded symbolic, expressive, grooming, and fidgeting gestures in 120 10-sec intervals of videotape per patient. We found that RHD patients made significantly more total gestures and grooming gestures with the hand ipsilateral to their lesion than did LHD patients. Furthermore, RHD patients made more total and grooming gestures with their right hand than NHD subjects did with either hand. There were no differences in gesture production between the right and left hands of NHD patients. These results suggest that RHD produces enhanced gesturing, particularly involving grooming behavior.
