“…These are apparent in the types of aphasia listed in Table 1, assuming adequate comprehension for the VNeST protocol (with cueing, see Edmonds, 2014). The findings also suggest that those with more severe forms of aphasia, concomitant AOS, and jargonistic and characteristic Wernicke's output can improve with VNeST (see Edmonds & Babb, 2011;Furnas & Edmonds, 2014;Edmonds, Mammino, et al, 2014;Edmonds, Obermeyer, et al, 2014 [P7 and P9]). The addition of writing in Step 1 (and potentially…”

This article examines Verb Network Strengthening Treatment (VNeST), a relatively new treatment approach for anomia in people with aphasia. The VNeST protocol aims to promote generalization to increased lexical retrieval of untrained words across a hierarchy of linguistic tasks, including single-word naming of nouns and verbs, sentence production, and discourse. The concept of the verb network relates to the centrality of the verb to the semantics and syntax of a sentence. The VNeST protocol elicits diverse agents (e.g., musician) and patients (e.g., tambourine) around trained verbs (e.g., shake) to activate a range of semantic concepts and personal responses to potentially facilitate generalization to a multitude of lexical items. The pre-and posttreatment generalization results for the 19 participants reported in English are analyzed. Participants represent a range of aphasia severities and types, including Broca's, transcortical motor, anomic, Wernicke's, and conduction aphasia. A previous study that evaluated 3 monolingual Korean speakers on a modified version of VNeST that accommodated Korean's verb final word order is also summarized. The findings across the 5 English studies and the Korean study revealed increased noun and verb naming and lexical retrieval in sentences and discourse on untrained items and tasks for more than half of the participants, suggesting preliminary efficacy for VNeST. Potential predictors and mechanisms of improvement are explored, and clinical implications, including consideration of goals, outcome measures, dosage, inclusion and evaluation of writing, and verb selection, are discussed. W ORD-FINDING difficulties (anomia) are widely prevalent in aphasia. They impact single-word-, sentence-, and discourselevel communication and all grammatical

Background: A number of computerised treatments have been developed for aphasia, but few have remediated typing, an important functional task, and/or been implemented over the Internet via teletherapy, which can increase access to therapeutic services. The current study created a computerised version of Verb Network Strengthening Treatment (VNeST) and administered it via telerehabilitation over the Internet. VNeST is a semantic treatment which seeks to improve lexical retrieval of words through the conceptual connection between verbs and thematic roles. Previous iterations of VNeST have shown improvement in both spoken and written lexical retrieval for people with moderate and moderate-to-severe aphasia. Aims: This study investigates changes to lexical retrieval with four hierarchical outcome measures. The research questions were: Does treatment using Computerised VNeST (VNeST-C) result in pre-to post-treatment increases in: (1) spoken and typed lexical retrieval of trained (e.g., The farmer is weighing the apples.) and untrained words (e.g., The carpenter is measuring the lumber.) in a picture description task, (2) untreated singleword naming accuracy of nouns and verbs in spoken and typed modalities, (3) spoken and typed lexical retrieval as measured by informative words, efficiency of production and complete utterances within discourse, and (4) standardised measures of cognitive and language abilities? Methods & Procedures: Two people with aphasia were treated three times per week for 8 weeks using the VNeST-C program. A single-subject experimental design was used to evaluate changes in trained and untrained stimuli and tasks. Additional pre-treatment and post-treatment testing was also conducted. Outcomes & Results: Results indicate improvements on lexical retrieval during sentence production of trained and untrained stimuli. Additional improvement was observed for single-word naming of untrained nouns and verbs in spoken and typed modalities and standardised measures of aphasia and writing-by-hand. Limited generalisation to discourse was also observed, including a general increase in word output and decrease in typed neologisms.

Effect of Verb Network Strengthening Treatment (VNeST) in Persons With Aphasia: Extension and Replication of Previous Findings

Abstract: The results of this study replicate previous findings and provide evidence that VNeST may promote specific and generalized lexical retrieval abilities and affect basic syntax production in both constrained and discourse production tasks.
