“…Collectively, these studies demonstrate the need for more research to understand variables (ie, severity, stage of recovery) that influence use-dependent learning. Additionally, recent research has called into question 44 the assumption that the neuroplasticity principle of intensity is a fundamental component of CILT. Thus, further studies that systematically manipulate neuroplasticity principles such as intensity and repetition are needed to understand the active treatment components of CILT and their effect on brain structure and function.…”

Given the profound impact of language impairment after stroke (aphasia), neuroplasticity research is garnering considerable attention as means for eventually improving aphasia treatments and how they are delivered. Functional and structural neuroimaging studies indicate that aphasia treatments can recruit both residual and new neural mechanisms to improve language function and that neuroimaging modalities may hold promise in predicting treatment outcome. In relatively small clinical trials, both non-invasive brain stimulation and behavioural manipulations targeting activation or suppression of specific cortices can improve aphasia treatment outcomes. Recent language interventions that employ principles consistent with inducing neuroplasticity also are showing improved performance for both trained and novel items and contexts. While knowledge is rapidly accumulating, larger trials emphasising how to select optimal paradigms for individualised aphasia treatment are needed. Finally, a model of how to incorporate the growing knowledge into clinical practice could help to focus future research.

“…Both intensive and distributed therapy had a positive effect on word retrieval for treated items immediately post-therapy and treatment effects were maintained for 1 month post-therapy. number of studies that have previously investigated the effect of dosage-controlled, treatment intensity on word retrieval outcomes in adults with chronic aphasia (Dignam et al, 2015;Mozeiko, Coelho, & Myers, 2015;Ramsberger & Marie, 2007;Raymer et al, 2006;Sage et al, 2011). Together, the results of these studies provide evidence that a distributed therapy schedule does not reduce the efficacy of anomia therapy and that therapy outcomes for distributed treatment may be comparable, if not superior, to intensive therapy in individuals with chronic aphasia.…”

“…However, direct comparisons with equivalent treatments delivered less intensively are generally lacking (Mozeiko et al, 2015). Due to the inherent variability in aphasia severity, this research question may more appropriately be considered using a within-subjects design.…”

“…CIUs/min demonstrates sensitivity to group differences, 31 stability over time, 31,63 and is recommended to document treatment-induced change, clinical decision making, and group research studies. 63 This measure has been used in treatment studies in stroke-induced aphasia, 62,[71][72][73][74] PPA, 24 and group research in traumatic brain injury. 75 Impressively, CIUs/ min corresponds to measures of social validity in aphasia outcomes research, such as listener perception and listener comfort.…”

Moving Toward Non-transcription based Discourse Analysis in Stable and Progressive Aphasia

2019

Measurement of communication ability at the discourse level holds promise for predicting how well persons with stable (e.g., stroke-induced), or progressive aphasia navigate everyday communicative interactions. However, barriers to the clinical utilization of discourse measures have persisted. Recent advancements in the standardization of elicitation protocols and the existence of large databases for development of normative references have begun to address some of these barriers. Still, time remains a consistently reported barrier by clinicians. Non-transcription based discourse measurement would reduce the time required for discourse analysis, making clinical utilization a reality. The purpose of this article is to present evidence regarding discourse measures (main concept analysis, core lexicon, and derived efficiency scores) that are well suited to non-transcription based analysis. Combined with previous research, our results suggest that these measures are sensitive to changes following stroke or neurodegenerative disease. Given the evidence, further research specifically assessing the reliability of these measures in clinical implementation is warranted.
