Book excerpt: In order to elucidate the critical factors that bring about treatment-induced language improvements, researchers have investigated many predictors of aphasia recovery; however, the evidence is often mixed. The mechanisms underlying differential responses to therapy have yet to be delineated. In this dissertation, it was hypothesized that factors which stimulate access to- and induce (re)learning of linguistic content may hold important predictive value. Chapter 1 is a review of existing research on three such factors, i) responsiveness to cues, ii) during-treatment improvement with repeated practice of the treatment protocol, and iii) executive control (EC). Chapter 2 presents treatment data from ten individuals with chronic post-stroke aphasia, who received a structured, phonological therapy for anomia. Group analyses revealed significant short- and long-term treatment gains and generalization. Computational modelling of speech error production pre- to post-treatment suggests that generalization was mediated by a strengthening of lexical-phonological connections. Individual treatment outcomes additionally demonstrated differential response to treatment among participants. The predictors of these outcomes were subsequently examined. Responsiveness to cues emerged as a significant predictor of overall naming improvements immediately post-treatment, while early improvement in therapy was predictive of generalization at follow-up. In Chapter 3, current evidence on the predictive value of EC in aphasia treatment outcomes was systematically reviewed. The studies reviewed (N =15) were heterogeneous with respect to the treatment approaches taken, and the EC tasks used. In addition, EC was poorly defined; EC task selection was broad and often lacking theoretical rationale. Nevertheless, EC abilities emerged as important indicators of treatment outcomes, especially in studies using specific EC tasks and structured treatment approaches. In Chapter 4, the predictive value of EC on treatment outcomes was investigated in the same sample of ten individuals from Chapter 2. Addressing some of the limitations identified in the existing literature, EC was defined and measured based on a theoretical framework and using a large battery of specific tasks. EC emerged as a robust predictor of treatment maintenance, suggesting a critical role for EC in encoding and consolidating treatment-related (re)learning. In Chapter 5 these findings are summarized and their broader implications for aphasia rehabilitation are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports behavioral and neurological results of a novel form of aphasia therapy---based on imitation of audiovisual speech---that was motivated by neurophysiological findings in human and non-human primates. The six-week intensive therapy program was completed by nineteen participants with post-stroke aphasia.Participants demonstrated significant improvement on the practiced repetition task and generalization to other tasks. Measures included subtests of the Western Aphasia Battery-Revised (Aphasia Quotient, Cortical Quotient, Repetition, Naming and Word Finding) and specific characteristics of narrative production (number and percent correct information units).This research investigated the role of performance variability within individuals during repetition to predict improvement with practice. We found that individuals demonstrating greater variability at baseline made greater improvement following treatment. Additionally, changes in variability over the course of treatment were negatively correlated with changes in performance. The more participants improve, the more consistent (less variable) their performance.On the narrative task, significant improvement was positively correlated with the number of therapy sessions that were completed, a result not explained by other traits that are often associated with aphasia recovery, such as lesion size and time since onset. The imitation therapy generalizes to other tasks, and more practice confers greater benefit.With functional neuroimaging during the resting state, we discovered two inter-related functional predictors of improvement in narrative production. Using a sliding window approach, we investigated the dynamic nature of resting state networks (RSNs) as they change over the course of therapy. An increase in the amount of time spent in one of the states---a state characterized by minimal correlation among the identified RSNs---predicted improvement on the narrative task. We interpreted this finding as evidence for adaptive segregation among the RSNs.Using a graph theoretical approach, we found a second functional predictor. By grouping the RSNs into communities, we examined network changes representative of segregation in the brain, and found increased RSN modularity to be positively correlated with behavioral improvement.These findings of previously unexplored behavioral and neurological changes and predictors associated with post-therapy recovery are consistent with an emerging approach to personalized (precision) aphasia treatment.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Aphasia affects 21-38% of acute stroke patients and is associated with low functional improvement. Most studies investigate the presence of aphasia, as a predictor of functional recovery, without analysing the nature and the severity of the linguistic impairment.Goal: The aim of the study is to investigate the predictors of functional recovery in post-stroke aphasic patients after intensive motor and speech rehabilitation. In particular, specific linguistic deficits and their severity were taken into account.Study design and population: 556 left hemispheric stroke patients were admitted from 2010 to 2016 to our intensive rehabilitation unit. 254 patients, with a complete functional assessment at admission, were included in this observational retrospective study.Methods: Clinical, functional, linguistic and rehabilitative features were considered as predictors. The outcome variable was defined as the achievement of the Minimal Clinical Important Difference (MCID) in the motor domain of the Functional Independence Measure (mFIM), defined as: discharge-mFIM u2013 admission-mFIM u2265 17. Univariate analysis (Pearsonu2019s chi-squared test or Mann-Whitney U test) was used to compare variables between the group of patients who reached a clinical significant improvement (MCID+) and the group who did not (MCIDu2013). Logistic regression analysis was performed for the statistically significant variables.Results: 50.7% of patients (129/254) were MCID+. Admission FIM scores were significantly higher in the MCID+ group (mFIM, p=0.019; cFIM, p=0.001). The groups were significantly different regarding the proportion of patients who were during the subacute stage of stroke3 (chi2=4.54; p

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary studies have highlighted initial severity of aphasia as an important determinant of aphasia recovery. Objective of the present study was to explore the predictors of initial aphasia severity after stroke. Bengali version of western aphasia battery (WAB), a validated scale, was used for language assessment. All patients underwent language examination during first week following stroke. Severity was assessed by calculating aphasia quotient (AQ) and taking into account the severity scale as in WAB. Lesion assessment was done by using Magnetic resonance imaging (3T) for ischemic stroke (if not contraindicated) and computed tomography for hemorrhagic stroke. Demographic factors (age, gender and number of years of formal education), lesion-related factors (type of stroke, lesion volume, cortical versus sub-cortical location and site of lesion) and initial aphasia type were independent variables while initial severity of aphasia (non-severe, AQ=50 or more; severe, AQ

Download or read book Collaborative capacity development to complement stroke rehabilitation in Africa written by Quinette Louw and published by AOSIS. This book was released on 2020-12-31 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: This scholarly book focuses on stroke in Africa. Stroke is a leading cause of disability among adults of all ages, contributing significantly to health care costs related to long term implications, particularly if rehabilitation is sub-optimal. Given the burden of stroke in Africa, there is a need for a book that focuses on functioning African stroke survivors and the implications for rehabilitation within the African context. In addition, there is a need to progress with contextualised, person-centred, evidence-based guidance for the rehabilitation of people with stroke in Africa, thereby enabling them to lead socially and economically meaningful lives. The research incorporated in the book used a range of primary and secondary methodological approaches (scoping reviews, systematic reviews, meta-analyses, descriptive studies, surveys, health economics, and clinical practice guideline methodology) to shed new insights into African-centred issues and strategies to optimise function post-stroke.
