Lee S, Faroqi-Shah Y. A Meta-Analysis of Anomia Treatment in Bilingual Aphasia: Within- and Cross-Language Generalization and Predictors of the Treatment Outcomes. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2024; 67:1558-1600. [PMID: 38629966 PMCID: PMC11087086 DOI: 10.1044/2024_jslhr-23-00026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 09/15/2023] [Accepted: 01/14/2024] [Indexed: 05/09/2024]
Abstract
PURPOSE The present meta-analysis investigated the efficacy of anomia treatment in bilingual and multilingual persons with aphasia (BPWAs) by assessing the magnitudes of six anomia treatment outcomes. Three of the treatment outcomes pertained to the "trained language": improvement of trained words (treatment effect [TE]), within-language generalization of semantically related untrained words (WLG-Related), and within-language generalization of unrelated words (WLG-Unrelated). Three treatment outcomes were for the "untrained language": improvement of translations of the trained words (cross-language generalization of trained words [CLG-Tx]), cross-language generalization of semantically related untrained words (CLG-Related), and cross-language generalization of unrelated untrained words (CLG-Unrelated). This study also examined participant- and treatment-related predictors of these treatment outcomes. METHOD This study is registered in the International Prospective Register of Systematic Reviews (PROSPERO) under the number CRD42023418147. Nine electronic databases were searched to identify word retrieval treatment studies of poststroke BPWAs of at least 6 months postonset. Pre- and posttreatment single-word naming scores were extracted for each eligible participant and used to calculate effect sizes (within-case Cohen's d) of the six treatment outcomes. Random-effects meta-analyses were conducted to assess weighted mean effect sizes of the treatment outcomes across studies. Multiple linear regression analyses were used to examine the effects of participant-related variables (pretreatment single-word naming and comprehension representing poststroke lexical processing abilities) and treatment-related variables (type, language, and duration). The methodological quality of eligible studies and the risk of bias in this meta-analysis were assessed. RESULTS A total of 17 published studies with 39 BPWAs were included in the meta-analysis. The methodological quality of the included studies ranged from fair (n = 4) to good (n = 13). Anomia treatment produced a medium effect size for TE (M = 8.36) and marginally small effect sizes for WLG-Related (M = 1.63), WLG-Unrelated (M = 0.68), and CLG-Tx (M = 1.56). Effect sizes were nonsignificant for CLG-Related and CLG-Unrelated. TE was significantly larger than the other five types of treatment outcomes. TE and WLG-Related effect sizes were larger for BPWAs with milder comprehension or naming impairments and for treatments of longer duration. WLG-Unrelated was larger when BPWAs received phonological treatment than semantic and mixed treatments. The overall risk of bias in the meta-analysis was low with a potential risk of bias present in the study identification process. CONCLUSIONS Current anomia treatment practices for bilingual speakers are efficacious in improving trained items but produce marginally small within-language generalization and cross-language generalization to translations of the trained items. These results highlight the need to provide treatment in each language of BPWAs and/or investigate other approaches to promote cross-language generalization. Furthermore, anomia treatment outcomes are influenced by BPWAs' poststroke single-word naming and comprehension abilities as well as treatment duration and the provision of phonological treatment.

CLINICAL LINGUISTICS & PHONETICS 2024; 38:477-507. [PMID: 37303193 DOI: 10.1080/02699206.2023.2221374] [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: 10/11/2021] [Revised: 05/02/2023] [Accepted: 05/30/2023] [Indexed: 06/13/2023]
Abstract
The primary goal of this study was to evaluate the treatment effects of semantic feature analysis (SFA) and phonological components analysis (PCA) on word retrieval processing in persons with aphasia (PWAs). After identifying the locus of the breakdown in lexical retrieval processing, 15 monolingual native Persian speakers with aphasia were divided into two groups. After three naming trials, participants with dominant semantic deficits received SFA, and participants with primary phonological deficits were provided with PCA three times a week for eight weeks. Both approaches improved participants' naming and performance on language tests, including spontaneous speech, repetition, comprehension, and semantic processing. However, the correct naming of treated and untreated items was higher in mild-to-moderate participants, with mostly circumlocution and semantic paraphasias in the SFA group. The same holds for mild-to-moderate participants with mostly phonemic paraphasia who received PCA therapy. Moreover, the results showed that participants' baseline naming performance and semantic abilities could be associated with the treatment outcomes. Although limited by a lack of a control group, this study provided evidence supporting the possible benefits of focusing on the locus of the breakdown for treating anomia through SFA and PCA approaches, specifically in participants with mild to moderate aphasia. However, for those with severe aphasia, the treatment choice may not be as straightforward because several variables are likely to contribute to this population's word-finding difficulties. Replication with larger, well-stratified samples, use of a within-subjects alternating treatment design and consideration of treatments' long-term effects are required to better ascertain the effects of focusing on the locus of breakdown for treatment of anomia.

Abstract
PURPOSE The influential relationship between executive functioning and aphasia rehabilitation outcomes has been addressed in a number of studies, but few have studied the effect of adding executive function training to linguistic therapies. The present study aimed to measure the effects of combining, within therapy sessions, executive function training and anomia therapy on naming and discourse abilities in people with chronic aphasia. METHOD A single-case experimental design with multiple baselines across participants was used. Four persons with chronic post-stroke aphasia received 12 sessions of a tailored treatment combining executive function training and semantic feature analysis (SFA) therapy. Naming accuracy of treated items was examined over the course of the treatment while control naming scores of untreated items and discourse measures were collected pre-treatment, immediately post-treatment, and 4 weeks post-treatment, in order to investigate the multidimensional effects of the treatment and their maintenance. RESULT Naming skills improved in all participants for treated and untreated items, were maintained over time, and were accompanied by improved discourse abilities. Visual and statistical analyses showed a significant treatment effect for naming skills in three out of the four participants. CONCLUSION A combination of executive function training and SFA treatment in people with chronic aphasia may improve both naming skills and discourse efficiency. Further studies are needed to substantiate these promising preliminary results.

Abstract
In this randomized, double-blind, sham-controlled trial of Cerebellar Stimulation for Aphasia Rehabilitation (CeSAR), we will determine the effectiveness of cathodal tDCS (transcranial direct current stimulation) to the right cerebellum for the treatment of chronic aphasia (>6 months post stroke). We will test the hypothesis that cerebellar tDCS in combination with an evidenced-based anomia treatment (semantic feature analysis, SFA) will be associated with greater improvement in naming untrained pictures (as measured by the change in Philadelphia Picture Naming Test), 1-week post treatment, compared to sham plus SFA. We will also evaluate the effects of cerebellar tDCS on naming trained items as well as the effects on functional communication, content, efficiency, and word-retrieval of picture description, and quality of life. Finally, we will identify imaging and linguistic biomarkers to determine the characteristics of stroke patients that benefit from cerebellar tDCS and SFA treatment. We expect to enroll 60 participants over five years. Participants will receive 15, 25-minute sessions of cerebellar tDCS (3-5 sessions per week) or sham tDCS combined with 1 hour of SFA treatment. Participants will be evaluated prior to the start of treatment, one-week post-treatment, 1-, 3-, and 6-months post treatment on primary and secondary outcome variables. The long-term aim of this study is to provide the basis for a Phase III randomized controlled trial of cerebellar tDCS vs sham with concurrent language therapy for treatment of chronic aphasia. Trial registration: The trial is registered with ClinicalTrials.gov NCT05093673.

Abstract
INTRODUCTION The purpose of the study was to pilot a working memory (WM) - and modified Semantic Feature Analysis (SFA) approach to treat word finding deficits in a group of people with aphasia (PwA). Two research questions were posed: 1. Will the group of PwA be able to complete the WM tasks used in the approach? 2. Will the approach improve naming performance in PwA? METHOD Three individuals with mild - moderate aphasia participated in this singlesubject multiple baseline treatment design. Pre-treatment assessments of language, and pre- to post-treatment assessments of WM abilities were carried out. The treatment protocol incorporated WM and linguistic tasks in order to improve naming accuracy across two treatment lists. Probes were carried out prior to treatment on each list, and at one-month following completion of treatment. Two outcome measures were obtained: Percent accuracy in completing the WM steps, and treatment effect sizes (Beeson & Robey, 2006). Additionally, modified t-tests (Crawford & Garthwaite, 2012; Crawford & Howell, 1998), were calculated in which post-treatment WM measures were compared against neurotypical control groups to detect any improvements in WM functions. RESULTS All three participants completed the WM steps with a high degree of accuracy. A range of small to large ESs were obtained for all three participants across the two treated lists, while no meaningful ESs were obtained for the control (untreated) list. All three participants demonstrated improved scores across most of the WM measures with significant improvements noted on certain WM assessments. CONCLUSIONS The findings revealed that the WM - SFA approach can be used successfully in individuals with mild - moderate aphasia. The proposed approach holds promise as feasible intervention designed to remediate anomia in PwA.

Abstract
Aphasia is a serious consequence of stroke that results in a breakdown in communication. The course of aphasia recovery differs between afflicted individuals, and responsiveness to treatment cannot be predicted. Aphasiologists continue to investigate numerous behavioral treatment protocols that have shifted their focus to complimentary rehabilitation strategies. The aim of this study is threefold. First, to summarize the different categories of aphasia interventions post-stroke, considering their respective protocols, and present available evidence on the effectiveness of those protocols. Second, to document the challenges regarding the prediction of aphasia treatment response post-stroke in individual patients. Third, to report the challenges faced by researchers in recruiting people with aphasia (PWA) for treatment studies, and provide recommendations on how to increase participant recruitment and retention. This study provides up-to-date information on (i) effective therapies and aphasia recovery processes, and (ii) research recruitment hurdles together with potential strategies for overcoming them.

Incorporating Metacognitive Strategy Training Into Semantic Treatment Promotes Restitutive and Substitutive Gains in Naming: A Single-Subject Investigation. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2023; 32:1979-2020. [PMID: 37433115 PMCID: PMC10561971 DOI: 10.1044/2023_ajslp-22-00230] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 10/22/2022] [Accepted: 02/17/2023] [Indexed: 07/13/2023]
Abstract
PURPOSE This study tested the effectiveness of a modified semantic feature analysis (SFA) treatment protocol that incorporated metacognitive strategy training (MST). Regarding its restitutive component, SFA most reliably results in improved word retrieval for treated items and untreated, semantically related items, but evidence of response generalization is often small/inconsistent. Regarding its substitutive component, SFA is thought to facilitate successful communication via habituation of the SFA circumlocution strategy. However, repeated practice with SFA's strategy in the absence of direct MST may not result in independent strategy use and/or generalization. Furthermore, people with aphasia's independent use of the SFA strategy in moments of anomia is presently underreported. To address these limitations, we incorporated MST into SFA and directly measured substitutive outcomes. METHOD Four people with aphasia participated in 24 treatment sessions of SFA + MST in a single-subject, A-B experimental design with repeated measurements. We measured word retrieval accuracy, strategy use, and explicit strategy knowledge. We calculated effect sizes to measure changes in word retrieval accuracy and strategy use and used visual inspection to assess gains in explicit strategy knowledge from pre- to posttreatment and retention. RESULTS Participants achieved marginally small to medium effects in word retrieval accuracy for treated; untreated, semantically related; and untreated, semantically unrelated items and marginally small to large effects in independent strategy use. Explicit strategy knowledge was variable. CONCLUSIONS Across participants, SFA + MST yielded positive changes in word retrieval accuracy or strategy use, or both. Positive changes in word retrieval accuracy were comparable to other SFA studies. Positive changes in strategy use demonstrate preliminary evidence of this treatment's ability to yield restitutive and substitutive gains. Overall, this study offers preliminary evidence of SFA + MST's effectiveness and highlights the importance of directly measuring SFA's substitutive outcomes, which showed that people with aphasia can respond to this treatment in multiple successful ways-not just improved target word production.

Abstract
OBJECTIVES Aphasia is an acquired language-cognitive disorder that highly affects an individual's speech, language, and communication skills. Recovery from aphasia requires attentive treatment since it is a long and dynamic process. This study aimed to show interactive benefits of combining classical intervention strategies with new technological approaches and demonstrating their effectiveness. MATERIALS AND METHODS A total of 40 individuals with Broca's aphasia were included in the study. The participants were divided into Application-1 Speech and Language Therapy, Application-2 Transcranial Magnetic Stimulation, Application-3 (consecutive Transcranial Magnetic Stimulation and Speech and Language Therapy), and Application-4 (Control Group) experimental groups, with 10 participants in each group. RESULTS Analysis indicated that individuals in the group in which Transcranial Magnetic Stimulation and Speech and Language Therapy were applied consecutively had further increases in speech fluency, repetition, and naming scores from pre-test to post-test (p<0.01). Picture naming and quality-of-life communication scores of individuals in the group in which Speech and Language Therapy was performed increased further from pre-test to post-test (p<0.01). CONCLUSIONS The results of the study showed a positive effect on language skills, naming scores, and participation in social life of Turkish-speaking aphasic individuals with the Speech and Language Therapy and Transcranial Magnetic Stimulation methods. The use of Transcranial Magnetic Stimulation alone is insufficient in this context. Although Speech and Language Therapy alone is effective in naming ability, Transcranial Magnetic Stimulation in addition to Speech and Language Therapy significantly increases the gain obtained with therapies.

Abstract
Semantic therapy in post-stroke aphasia typically focusses on strengthening links between conceptual representations and their lexical-articulatory forms to aid word retrieval. However, research has shown that semantic deficits in this group can affect both verbal and non-verbal tasks, particularly in patients with deregulated retrieval as opposed to degraded knowledge. This study, therefore, aimed to facilitate semantic cognition in a sample of such patients with post-stroke semantic aphasia (SA) by training the identification of both strong and weak semantic associations and providing explicit pictorial feedback that demonstrated both common and more unusual ways of linking concepts together. We assessed the effects of this training on (i) trained and untrained items; and (ii) trained and untrained tasks in eleven individuals with SA. In the training task, the SA group showed improvement with practice, particularly for trained items. A similar untrained task using pictorial stimuli (Camel and Cactus Test) also improved. Together, these results suggest that semantic training can be beneficial in patients with SA and may show some degree of generalization to untrained situations. Future research should seek to understand which patients are most likely to benefit from this type of training.

Abstract
INTRODUCTION Anomia affects numerous persons with aphasia. Treatment effects of anomia group therapy have been reported, but the evidence is not comprehensive. This study aimed to explore treatment effects of a naming treatment compared with a non-naming treatment delivered in a group setting. METHODS In a randomized controlled trial, 17 participants with chronic poststroke aphasia underwent group therapy, 2 hours a session, 3 times per week, for a total of 20 hours. The treatment given in the naming group was modified semantic feature analysis (SFA). Treatment content in the non-naming group comprised auditory comprehension, copying text, and reading. The primary outcome measure was accuracy in confrontation naming of participant-selected trained nouns and verbs. Generalization effects were evaluated in single-word naming, connected speech, and everyday communication. RESULTS Participants in both groups significantly improved their naming of trained items. There were no differences between the groups. The treatment effect did not remain at follow-up 10 weeks after therapy. No other statistically significant changes occurred in either group. CONCLUSIONS Group intervention can improve naming ability in individuals with chronic aphasia. However, similar treatment effects can be achieved using a non-naming treatment as using a naming treatment, such as modified SFA. Further research is warranted to identify the most important elements of anomia group therapy.

Abstract
In this study, we compared the orthographic and semantic preferences of healthy adults and age and gender matched adults with aphasia, an acquired language disorder. Previous research in word retrieval and word associations has addressed semantic and phonological connections, but it has not as often included analyses of orthographic skills. We matched (on age and gender) 10 neurotypical adults and 11 older adults with aphasia and administered to both groups a lexical discrimination task requiring them to select, from 18 choices, those words that were most different from three words (daughter, laughter, son). Among the choices were foil words (e.g., daughter), orthographic similarities (laughter) and semantic similarities (son). Results revealed that individuals with aphasia focused on orthographic differences, while healthy adults chose semantic differences. Further studies should further explore this orthographic focus to develop treatment strategies, using behavioral and objective measures, for word-finding deficits in aphasia.

Abstract
There is a long history of behavioral interventions for poststroke aphasia with hundreds of studies supporting the benefits of aphasia treatment. However, interventions for aphasia are complex with many interacting components, and no one treatment is appropriate for all persons with aphasia. We present a novel, simple framework for classifying aphasia interventions. The framework is incorporated within the overarching International Classification of Functioning, Disability, and Health (ICF) model and is consistent with the commonly-held definition that aphasia is a multimodality disorder that impairs, in varying degrees, the understanding and expression of both oral and written language modalities. Furthermore, within the language impairment level, it distinguishes between the linguistic areas of phonology, semantics, and syntax that may be impaired individually or in combination. We define the terminology of the proposed framework and then categorize some common examples of behavioral interventions for post-stroke aphasia. We describe some of these interventions in greater detail to illustrate the extensive toolbox of evidence-based treatments for aphasia. We address some key issues that clinicians, usually speech-language pathologists, consider when selecting interventions for their specific patients with aphasia, including dose. Finally, we address various models of service delivery for persons with aphasia such as Intensive Comprehensive Aphasia Programs (ICAPs) and Aphasia Centers.

Abstract
PURPOSE Repetition priming has been suggested as a method for targeting implicit processes in anomia treatment. Prior studies have used masked priming for this purpose. This study extends that work with visible primes, a more clinically feasible approach. METHOD This study used a single-subject design across three participants with aphasia. Treatment involved repeated exposure to identity primes (trained condition) or sham primes (untrained condition) paired with pictures. Analyses assessed acquisition effects for trained items and untrained items that were seen during the training period, generalization to untrained items that had not been seen, and generalization to broader language skills, immediately and 3 months post-treatment. RESULTS All participants improved in naming trained items immediately after treatment, with greater improvements for trained than for untrained items. All participants maintained some degree of improvement on trained items 3 months post-treatment, although the degree differed across participants. Inconsistent generalization occurred to unexposed items. Improvements were noted in some areas of broader language ability, although these varied. CONCLUSIONS These data suggest a repetition priming treatment paradigm may increase naming accuracy for individuals with anomia and may benefit other aspects of language. Participant factors may have influenced response to treatment. Directions for future investigation are discussed.

INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2021; 56:1114-1131. [PMID: 34260119 DOI: 10.1111/1460-6984.12637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 05/11/2021] [Accepted: 05/14/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Treatment fidelity (TF), that is, the degree to which the treatment delivery has adhered to protocol, is an important aspect of establishing treatment validity and reliability. Research has shown that establishing TF is only done in a small percentage of aphasia treatment studies. AIMS This project supports the work of the CommuniCATE study, which explored the benefits of technology-enhanced aphasia therapy on participants' reading, writing, speech and conversation skills. It examines the TF of the Reading strand of the CommuniCATE project by assessing whether the therapy adhered to the protocol. The following research questions were asked: Does treatment delivery adhere to treatment protocol? Does the degree of TF vary according to the person delivering the therapy (i.e. student therapist or qualified therapist)? Does the degree of TF vary over time (early treatment sessions compared with later treatment sessions)? Was the checklist tool reliable? METHODS & PROCEDURES This study assessed the fidelity of 38 retrospective video recordings of therapy. It used a checklist measure of criteria to which the delivery of the sessions should adhere, and against which the sessions were rated. Participants were the people with aphasia receiving therapy, the students and qualified speech and language therapists delivering therapy, and the independent raters assessing the sessions. A sample of sessions was randomly chosen, including sessions delivered by qualified therapists and by students, and sessions from different time points in the treatment process. The fidelity was rated by the first author, and the fidelity rating calculated as a percentage. Comparisons in fidelity scores for the different variables were drawn using Mann-Whitney tests. The reliability of the checklist was assessed through inter and intra-rater reliability testing, and the results were analysed using Kappa statistics. OUTCOMES & RESULTS High fidelity was found across all therapy conditions with a mean score of 98.2%. Fidelity scores were not affected by the administrator of therapy; sessions delivered by qualified and student therapists were rated equally highly. There was a small but significant effect of time, with later treatment sessions scoring more highly than earlier sessions. However, scores across both periods > 90%. Inter-rater reliability found a high percentage agreement of 93.3% and a Poor Kappa agreement level. Intra-rater agreement found a high percentage agreement of 97.3% and a Fair Kappa agreement level. CONCLUSIONS & IMPLICATIONS The CommuniCATE reading therapy was implemented as per the protocol across time points, and withstood delegation to students. The high fidelity and good reliability scores have positive implications for the study's validity and reliability, and for the study's replication. WHAT THIS PAPER ADDS What is already known on the subject TF refers to the degree to which the delivery of core components of a treatment matches the implementation guidelines, that is, the adherence to protocol. Despite the acknowledged importance of TF reporting, this is often neglected in the literature. What this paper adds to existing knowledge This paper shows that the TF assessment of the CommuniCATE study (reading strand) found a 98.2% fidelity score, and that high fidelity was not compromised across treatment conditions. This paper outlines the principles of TF and highlights the need for measures to be in place to establish TF, for example, manuals, training and supervision; and to monitor TF, for example, via the use of checklists. This paper also underlines the scarcity of TF measures and checks in aphasia research. This paper therefore serves as a model of TF practice in aphasia therapy research. What are the potential or actual clinical implications of this work? This study contributes to the findings of the CommuniCATE project (reading strand), and the high fidelity findings enhance the validity of the project and indicate that the therapy manual and training enable accurate implementation of delivery. This paper also contributes to the literature on TF evaluation in aphasia studies, which is presently lacking, and highlights the need for increased focus on the optimum strategies of TF reporting.

Abstract
Outcomes for patients with lower-grade gliomas (LrGGs) continue to improve with advances in molecular characterization and treatment. However, cognitive sequela from the tumor and its treatment leave a significant impact on health-related quality of life for these patients. Several factors affect each patient's cognition, such as tumor location, treatment, medication, and comorbidities. However, impairments of processing speed, attention, concentration, working memory, and executive function are common across LrGG patients. Cognitive rehabilitation strategies, well established in traumatic brain injury and stroke populations, are based on neural plasticity and functional reorganization. Adapting these strategies for implementation in patients with brain tumors is an active area of research. This article provides an overview of cognitive domains commonly impaired in LrGG patients and evidence for the use of cognitive rehabilitation strategies to address these impairments with the goal of improving health-related quality of life in this patient population.

Convergence of heteromodal lexical retrieval in the lateral prefrontal cortex. Sci Rep 2021; 11:6305.

Abstract
Lexical retrieval requires selecting and retrieving the most appropriate word from the lexicon to express a desired concept. Few studies have probed lexical retrieval with tasks other than picture naming, and when non-picture naming lexical retrieval tasks have been applied, both convergent and divergent results emerged. The presence of a single construct for auditory and visual processes of lexical retrieval would influence cognitive rehabilitation strategies for patients with aphasia. In this study, we perform support vector regression lesion-symptom mapping using a brain tumor model to test the hypothesis that brain regions specifically involved in lexical retrieval from visual and auditory stimuli represent overlapping neural systems. We find that principal components analysis of language tasks revealed multicollinearity between picture naming, auditory naming, and a validated measure of word finding, implying the existence of redundant cognitive constructs. Nonparametric, multivariate lesion-symptom mapping across participants was used to model accuracies on each of the four language tasks. Lesions within overlapping clusters of 8,333 voxels and 21,512 voxels in the left lateral prefrontal cortex (PFC) were predictive of impaired picture naming and auditory naming, respectively. These data indicate a convergence of heteromodal lexical retrieval within the PFC.

Abstract
Although the treatment for lexical anomia in individuals with aphasia (IWA) was shown effective, little is known about the optimal treatment intensity required. The aim of this study was to verify whether intensive and non-intensive treatments led to different outcomes when parameters of intensity are rigorously controlled. Six IWA with post-stroke lexical anomia received phonological treatment at two distinct frequencies: intensive (four times a week) and non-intensive (once a week). Results showed that both treatments were equally effective. This finding is especially relevant in contexts in which speech-language therapy delivery services are limited.

Abstract
Purpose Aphasia research demonstrates increasing interest in the treatment of verb retrieval deficits. This systematically conducted scoping review reports on the level and fidelity of the current evidence for verb treatments; on its effectiveness regarding the production of trained and untrained verbs, functional communication, sentences, and discourse; and on the potential active ingredients. Recommendations to guide clinical decision making and future research are made. Method The computerized database search included studies from January 1980 to September 2018. The level of evidence of each study was documented, as was fidelity in terms of treatment delivery, enactment, and receipt. Studies were also categorized according to the treatment methods used. Results Thirty-seven studies were accepted into the review, and all but 1 constituted a low level of evidence. Thirty-three studies (89%) described treatment in sufficient detail to allow replication, dosage was poorly reported, and the fidelity of treatment was rarely assessed. The most commonly reported treatment techniques were phonological and semantic cueing in 25 (67.5%) and 20 (54%) studies, respectively. Retrieval of trained verbs improved for 80% of participants, and improvements generalized to untrained verbs for 15% of participants. There was not sufficient detail to evaluate the impact of treatment on sentence production, functional communication, and discourse. Conclusions The evidence for verb treatments is predominantly of a low level. There are encouraging findings in terms of treatments being replicable; however, this is tempered by poor monitoring of treatment fidelity. The quality of verb treatment research would be improved by researchers reaching consensus regarding outcome measures (including generalization to, e.g., sentences and discourse) by manualizing treatment to facilitate implementation and exploring the opinions of participants. Finally, while treatment is largely effective in improving production of trained verbs, lack of generalization to untrained items leads to the recommendation that personally relevant verbs are prioritized.

Abstract
Purpose The ultimate goal of anomia treatment should be to achieve gains in exemplars trained in the therapy session, as well as generalization to untrained exemplars and contexts. The purpose of this study was to test the efficacy of phonomotor treatment, a treatment focusing on enhancement of phonological sequence knowledge, against semantic feature analysis (SFA), a lexical-semantic therapy that focuses on enhancement of semantic knowledge and is well known and commonly used to treat anomia in aphasia. Method In a between-groups randomized controlled trial, 58 persons with aphasia characterized by anomia and phonological dysfunction were randomized to receive 56-60 hr of intensively delivered treatment over 6 weeks with testing pretreatment, posttreatment, and 3 months posttreatment termination. Results There was no significant between-groups difference on the primary outcome measure (untrained nouns phonologically and semantically unrelated to each treatment) at 3 months posttreatment. Significant within-group immediately posttreatment acquisition effects for confrontation naming and response latency were observed for both groups. Treatment-specific generalization effects for confrontation naming were observed for both groups immediately and 3 months posttreatment; a significant decrease in response latency was observed at both time points for the SFA group only. Finally, significant within-group differences on the Comprehensive Aphasia Test-Disability Questionnaire (Swinburn, Porter, & Howard, 2004) were observed both immediately and 3 months posttreatment for the SFA group, and significant within-group differences on the Functional Outcome Questionnaire (Glueckauf et al., 2003) were found for both treatment groups 3 months posttreatment. Discussion Our results are consistent with those of prior studies that have shown that SFA treatment and phonomotor treatment generalize to untrained words that share features (semantic or phonological sequence, respectively) with the training set. However, they show that there is no significant generalization to untrained words that do not share semantic features or phonological sequence features.

Abstract
Purpose This meta-analysis synthesizes results from published studies that used semantic feature analysis (SFA) treatment to improve naming for people with aphasia. It examines how both person- and treatment-related variables affected the likelihood of correct naming responses in individual probe sessions for both acquisition (treated) and generalization (untreated) stimuli. Method The meta-analysis compiled data from 12 studies analyzing a total of 35 participants with aphasia. It used mixed-effects models as a novel statistical tool to examine the effects of 2 sets of variables on naming performance: treatment-related variables, including treatment phase (baseline vs. treatment), dosage (number of treatment sessions), and stimulus type (treated vs. untreated, semantically related vs. unrelated items), and person-specific variables, including degree of language impairment and demographic variables (age, time poststroke). Results Results of the meta-analysis revealed that SFA intervention promoted increased naming accuracy during naming probes when comparing baseline and treatment phases. In addition, increased dosages of SFA were associated with increased naming accuracy, and treatment-related gains were larger for acquisition (treated) than generalization (untreated) stimuli, likewise for related versus unrelated generalization stimuli. Furthermore, a subset of person-specific variables was predictive of SFA-related gains: Language impairment variables were related to treatment-related changes in naming performance, but demographic variables were not. Conclusion These results provide group-level evidence for the efficacy of SFA as well as preliminary estimates of how much naming performance benefit is engendered by varying dosages of SFA. The results also provide promising and previously unobserved evidence of potential person-level predictors of SFA treatment response.

Abstract
BACKGROUND Aphasia is an acquired language disorder that occurs secondary to brain injury, such as stroke. It causes communication difficulties that have a significant impact on quality of life and social relationships. Although the efficacy of speech-language therapy has been clearly demonstrated in this population, long-term services are currently limited due to logistical and financial constraints. In this context, the potential contribution of technology, such as smart tablets, is worth exploring, especially to improve vocabulary that is relevant in daily life. AIMS The main aim was to investigate the efficacy of a self-administered treatment using a smart tablet to improve naming of functional words in post-stroke anomia. METHODS & PROCEDURES Four adults with post-stroke aphasia took part in the study. An ABA design with multiple baselines was used to compare naming performances for four equivalent lists: (1) trained with functional words chosen with the participant; (2) trained with words randomly chosen from a picture database; (3) exposed but not trained; and (4) not exposed (control). OUTCOMES & RESULTS For all participants, the treatment self-administered at home (four times/week for 4 weeks) resulted in a significant improvement for both sets of trained words that was maintained 2 months after the end of treatment. Moreover, in two participants, evidence of generalization to conversation was found. CONCLUSIONS & IMPLICATIONS This study confirms the efficacy of using smart tablets to improve naming in post-stroke aphasia. Although more studies are needed, the use of new technologies is unquestionably a promising approach to improve communication skills in people with aphasia, especially by targeting vocabulary that is relevant to them in their daily lives.

Abstract
Currently, public services in speech-language pathology for primary progressive aphasia (PPA) are very limited, although several interventions have been shown to be effective. In this context, new technologies have the potential to enable people with PPA to improve their communication skills. The main aim of this study was to investigate the efficacy of a self-administered therapy using a smart tablet to improve naming of functional words and to assess generalization to an ecological conversation task. Five adults with PPA completed the protocol. Using an ABA design with multiple baselines, naming performance was compared across four equivalent lists: (1) trained with functional words; (2) trained with words from a picture database; (3) exposed but not trained; and (4) not exposed (control). Treatment was self-administered four times a week for a period of four consecutive weeks. A significant improvement for trained words was found in all five participants, and gains were maintained two months post-treatment in four of them. Moreover, in three participants, evidence of generalization was found in conversation. This study supports the efficacy of using a smart tablet to improve naming in PPA and suggests the possibility of generalization to an ecological context.

Abstract
PURPOSE The purpose of this study was to review treatment studies of semantic feature analysis (SFA) for persons with aphasia. The review documents how SFA is used, appraises the quality of the included studies, and evaluates the efficacy of SFA. METHOD The following electronic databases were systematically searched (last search February 2017): Academic Search Complete, CINAHL Plus, E-journals, Health Policy Reference Centre, MEDLINE, PsycARTICLES, PsycINFO, and SocINDEX. The quality of the included studies was rated. Clinical efficacy was determined by calculating effect sizes (Cohen's d) or percent of nonoverlapping data when d could not be calculated. RESULTS Twenty-one studies were reviewed reporting on 55 persons with aphasia. SFA was used in 6 different types of studies: confrontation naming of nouns, confrontation naming of verbs, connected speech/discourse, group, multilingual, and studies where SFA was compared with other approaches. The quality of included studies was high (Single Case Experimental Design Scale average [range] = 9.55 [8.0-11]). Naming of trained items improved for 45 participants (81.82%). Effect sizes indicated that there was a small treatment effect. CONCLUSIONS SFA leads to positive outcomes despite the variability of treatment procedures, dosage, duration, and variations to the traditional SFA protocol. Further research is warranted to examine the efficacy of SFA and generalization effects in larger controlled studies.

Abstract
OBJECTIVE The aim is to update our clinical recommendations for evidence-based language rehabilitation of people with aphasia, based on a systematic review of the literature from 1999 to 2015. DATA SOURCES Articles referred to in this systematic review of the Medline and PubMed published in English language literatures were from 1998 to 2015. The terms used in the literature searches were aphasia and evidenced-based. STUDY SELECTION The task force initially identified citations for 51 published articles. Of the 51 articles, 44 studies were selected after further detailed review. Six articles, which were not written in English, and one study related to laryngectomy rehabilitation interventions, were excluded from the study. This study referred to all the important and English literature in full. RESULTS Aphasia is the linguistic disability, which usually results from injuries to the dominant hemisphere of the brain. The rehabilitation of aphasia is until in the process of being debated and researched. Evidence-based medicine (EBM), EBM based on the clinical evidence, promotes the practice of combining the clinicians' first-hand experience and the existing objective and scientific evidence encouraging making decisions based on both empirical evidence and the scientific evidence. Currently, EBM is being gradually implemented in the clinical practice as the aim of the development of modern medicine. CONCLUSIONS At present, the research for the aphasia rehabilitation mainly focuses on the cognitive language rehabilitation and the intensive treatment and the precise treatment, etc. There is now sufficient information to support evidence-based protocols and implement empirically-supported treatments for linguistic disability after traumatic brain injury and stroke, which can be used to develop linguistic rehabilitation guidelines for patients with aphasia.
