Talking About Aphasia: A Social Media Analysis Of What Individuals With Aphasia And Communication Partners Convey About Functional Discourse, Anna Williams

Graduate Theses and Dissertations

This study aimed to blend what we know about aphasia and functional communication. Specifically, how individuals with aphasia are functionalizing communication on the social media platform of YouTube. Extensive clinically significant literature exists on functional communication within speech-language pathology that provides practical guidance for clinical applications. Moreover, an emerging theoretical framework on functional communication and aphasia has sparked fresh insights, particularly from the perspective of individuals with aphasia. This perspective holds promise for exploring how individuals and their families leverage social media for functional communication. This study aims to integrate established clinical research findings on functional communication with the evolving …

Discourse- And Lesion-Based Aphasia Quotient Estimation Using Machine Learning, Nicholas Riccardi, Satvik Nelakuditi, Dirk B. Den Ouden, Chris Rorden, Julius Fridriksson, Rutvik H. Desai

Communication Sciences and Disorders Faculty Articles and Research

Discourse is a fundamentally important aspect of communication, and discourse production provides a wealth of information about linguistic ability. Aphasia commonly affects, in multiple ways, the ability to produce discourse. Comprehensive aphasia assessments such as the Western Aphasia Battery-Revised (WAB-R) are time- and resource-intensive. We examined whether discourse measures can be used to estimate WAB-R Aphasia Quotient (AQ), and whether this can serve as an ecologically valid, less resource-intensive measure. We used features extracted from discourse tasks using three AphasiaBank prompts involving expositional (picture description), story narrative, and procedural discourse. These features were used to train a machine learning model …

”To Be Or Not To Be – It’S Good”: Actor And Student Experiences In A Drama Club For People With Aphasia, Jade K. Hannan

Senior Theses

Individuals with aphasia, a disorder caused by damage to the brain’s language network, confront a variety of social and emotional struggles. While leaving their cognition largely intact, aphasia tremendously impacts a person’s ability to communicate confidently, fracturing their social network and contributing to feelings of loneliness and frustration. To address this persistent need in the chronic aphasia population, the Play on Words drama club at the University of South Carolina provides a forum for people with aphasia (PWA) to engage in dramatic exercises focused on non-verbal communication of emotions, ideas, and stories, culminating the production of an original devised play. …

Dissociating Reading And Auditory Comprehension In Persons With Aphasia, Rachel M. Harrington, Sigfus Kristinsson, Janina Wilmskoetter, Natalie Busby, Dirk Den Ouden, Chris Rorden, Julius Fridriksson Ph.D., Leonardo Bonilha

Faculty Publications

Language comprehension is often affected in individuals with post-stroke aphasia. However, deficits in auditory comprehension are not fully correlated with deficits in reading comprehension and the mechanisms underlying this dissociation remain unclear. This distinction is important for understanding language mechanisms, predicting long-term impairments and future development of treatment interventions. Using comprehensive auditory and reading measures from a large cohort of individuals with aphasia, we evaluated the relationship between aphasia type and reading comprehension impairments, the relationship between auditory versus reading comprehension deficits and the crucial neuroanatomy supporting the dissociation between post-stroke reading and auditory deficits. Scores from the Western Aphasia …

Visualizing Communication Disorders Through Art, Adriana Reyes

Mahurin Honors College Capstone Experience/Thesis Projects

This art series visualizes the signs, symptoms, and intervention strategies for various speech and language disorders. The illustrations were lightly sketched onto the canvas and oil-based paint was used as the medium. In the art series, the disorders depicted are childhood apraxia of speech, dysarthria, articulation disorder, and aphasia. The public and parents may be uninformed or have misconceptions about communication disorders. Therefore, it is important to educate others about communication disorders to construct a network of support, respect, and learning different ways to communicate since speech and language disorders can make a profound impact on a person’s life.

It's Day To Day Problems: Experiences Of People With Aphasia Who Live Alone, Deborah Hersh, Clare Williamson, Emily Brogan, Mandy Stanley

Research outputs 2022 to 2026

Purpose: Living alone is increasing and associated with health and social risks. Aphasia compounds these risks but there is little research on how living alone interacts with aphasia. This study is a preliminary exploration of this issue. Method: Five people with aphasia who lived alone participated in two supported semi-structured interviews, with the second interview including sharing an artefact that held significance for living alone with aphasia. Interviews were recorded, transcribed verbatim, and analysed through reflexive thematic analysis. Result: Four themes encompassed meaning-making about living alone with aphasia: relationships and reliance on others; risk, vulnerability, and uncertainty; loneliness and time …

Understanding And Addressing The Individualized Emotional Impact Of Aphasia: A Framework For Speech-Language Pathologists, Tyson G. Harmon

Faculty Publications

Emotion plays an integral role in communication and has long been considered relevant to aphasia rehabilitation. Speech-language pathologists (SLPs), however, may sometimes wonder how or whether to address emotional responses. The purpose of the present tutorial was to (1) present a framework that clinicians can use to understand individualized emotional responses in aphasia and (2) discuss examples of how the framework informs practical strategies that SLPs can use to provide emotional support to PWA. Drawing upon a cognitive-motivational-relational theory of emotions perspective combined with emerging research in aphasia, I show that emotion impacts and is impacted by both language processing …

Effects Of Cognitive And Social Demands On Linguistic Production For People With Moderate, Mild, Or No Aphasia, Tyson G. Harmon, Emily Mcdonald, Kyle Steele

Faculty Publications

Background

Most everyday communication occurs in situations where cognitive and social demands are present. These types of situations may compound language deficits for people with aphasia (PWA). An understanding of the language interference that may occur from cognitive and social demands is an important precursor for assessment and intervention that addresses everyday communication situations.

Aims

To determine how cognitively and socially demanding conditions affect micro- and macrolinguistic production for people with moderate, mild, or no aphasia during narrative discourse and to compare effects among groups.

Method

Thirty participants with mild (n = 9), moderate (n = 9), or no (n …

The Impact Of Treatment Dosage On Cognitive-Linguistic Outcomes Of Patients With Aphasia: An Investigation Of Three Service Delivery Models, Adele J. Derendinger

Graduate Student Theses, Dissertations, & Professional Papers

This study addresses the gap in literature by directly comparing the effectiveness of Intensive Comprehensive Aphasia Programs (ICAPs) and modified ICAPs (mICAPs) to usual care service delivery models for people with aphasia. Through a prospective study design, cognitive-linguistic function change scores across different service delivery models were examined. The findings reveal significant within-group improvements in cognitive-linguistic function for participants in ICAPs, with some improvement seen in mICAPs and usual care conditions. Intensive models demonstrated greater improvement compared to non-intensive usual care models, particularly evident in the Western Aphasia Battery – Revised and the Boston Naming Test – Second Edition. …

The Influence Of Intensive Treatment In A Cohort Model On Psychosocial Well-Being Of Patients With Aphasia: An Investigation Of Patients’ Quality Of Life Across Three Service Delivery Models, Helena Riley

Graduate Student Theses, Dissertations, & Professional Papers

Aphasia, a common communication disorder following a stroke, significantly impacts psychosocial wellbeing and quality of life. Despite advancements in rehabilitation frameworks, traditional impairment-based interventions prevail, leaving gaps in addressing holistic needs. This study aims to compare patient-reported outcome measures (PROMs) between intensive comprehensive aphasia programs (ICAP), modified ICAPs (mICAPs) and individual usual care (UC) service delivery models for aphasia intervention. Eighteen participants with aphasia were broadly recruited for this study. Each completed a series of PROMs pre-and post-treatment examining psychosocial wellbeing, communicative participation, and health related quality of life. Results indicate that intensive programs show potential for greater gains in …

Impact Of Covid-19 On Individuals With Aphasia: Effects On Quality Of Life And Communication, Kaci L. Gammon

Honors College Theses

Speech-language pathologists (SLPs) help people with aphasia (PWA) manage their communication symptoms and become more independent by supporting them linguistically and emotionally. During COVID-19, speech and language services were not as readily available to PWA due to quarantine restrictions resulting in isolation within this population. Individuals with aphasia had to redirect and find a new way to function daily. This study explored factors that affected quality of communication and quality of life for PWA during the pandemic, including technology, living situation, timing of stroke, and speech-language pathology services. Through an online survey, PWA from across the country expressed how their …

Feasibility Of An Abstract Verb Naming Treatment For Aphasia, Dallin J. Bailey, Lisa Bunker, Julie L. Wambaugh

Faculty Publications

Purpose

Verb production impairments in aphasia have important implications for sentence production and communication in general. Verbs with low concreteness may be especially important for certain functional uses, and yet limited data regarding their response to treatment are available. This study was designed to examine a novel behavioral treatment approach to improve low concreteness verb naming in persons with aphasia.

Method

Three persons with nonfluent aphasia participated in a single-subject experimental design research study examining the feasibility of the novel treatment. The treatment was based on approaches that target the verb as the central node of meaning during sentence construction. …

Grammatical Parallelism In Aphasia: A Lesion-Symptom Mapping Study, William Matchin, Dirk B. Den Ouden, Alexandra Basilakos, Brielle Caserta Stark, Julius Fridriksson, Gregory Hickok

Communication Sciences and Disorders Faculty Articles and Research

Sentence structure, or syntax, is potentially a uniquely creative aspect of the human mind. Neuropsychological experiments in the 1970s suggested parallel syntactic production and comprehension deficits in agrammatic Broca’s aphasia, thought to result from damage to syntactic mechanisms in Broca’s area in the left frontal lobe. This hypothesis was sometimes termed overarching agrammatism, converging with developments in linguistic theory concerning central syntactic mechanisms supporting language production and comprehension. However, the evidence supporting an association among receptive syntactic deficits, expressive agrammatism, and damage to frontal cortex is equivocal. In addition, the relationship among a distinct grammatical production deficit in aphasia, …

Physiological Arousal, Attentiveness, Emotion, And Word Retrieval In Aphasia: Effects And Relationships, Tyson G. Harmon, Angela Johnson, Vivian Ward, Shawn Nissen

Faculty Publications

Purpose: To (a) compare physiological arousal and attentiveness during a confrontational naming task between participants with aphasia and a control group across four conditions that varied according to emotionality of presented stimuli and (b) explore relationships among physiological arousal, attentiveness, perceived arousal, and naming performance. We hypothesized that participants with aphasia would show lower levels of arousal and attentiveness than control participants and that emotional conditions would lead to increased physiological arousal and attentiveness.

Method: Eight participants with aphasia and 15 control participants completed a confrontational naming task under positive, negative, and neutral conditions and rated their perceived arousal after …

Telling Stories In Noise: The Impact Of Background Noises On Spoken Language For People With Aphasia, Tyson G. Harmon, Brenna Scadden Nelson, Christopher Dromey, Kirsten Dixon Clawson

Faculty Publications

Purpose: Determine how different background noise conditions affect the spoken language of participants with aphasia during a story retell task.

Method: Participants included 11 adults with mild to moderate aphasia and 11 age- and gender-matched controls. Participants retold stories in a silent baseline and five background noise conditions (conversation, monologue, phone call, cocktail, pink noise). Dependent measures of speech acoustics (fundamental frequency, mean intensity), speech fluency (speech rate, disfluent words), and language production (correct information units, lexical errors, lexical diversity, and cohesive utterances) were compared between groups and across conditions.

Results: Background noise resulted in higher fundamental frequency (F_{0 …}

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

The Effect Of Visual Feedback On Vocal Compensation Abilities In Individuals With Post-Stroke Aphasia, Marissa Rylee Olson

Theses and Dissertations

Speech production is a complex and highly organized process comprised of various sensory and perceptual components. Post-stroke aphasia can impair speech production abilities by interrupting individuals’ ability to detect and correct speech errors and produce their targeted behavior. Contemporary models of speech production aim to understand the relationship between sensory systems and the human ability to produce perceptually accurate speech. This study seeks to understand the relationship between visual feedback and vocal compensation abilities in individuals with post-stroke aphasia to determine the effectiveness of incorporating visual feedback into therapeutic expressive language intervention. It was hypothesized that that the multi-sensory experimental …

Benefit Of Visual Speech Information For Word Comprehension In Post-Stroke Aphasia, Anna Krason, Gabriella Vigliocco, Marja-Liisa Mailend, Harrison Stoll, Rosemary Varley, Laurel J. Buxbaum

Moss-Magee Rehabilitation Papers

Aphasia is a language disorder that often involves speech comprehension impairments affecting communication. In face-to-face settings, speech is accompanied by mouth and facial movements, but little is known about the extent to which they benefit aphasic comprehension. This study investigated the benefit of visual information accompanying speech for word comprehension in people with aphasia (PWA) and the neuroanatomic substrates of any benefit. Thirty-six PWA and 13 neurotypical matched control participants performed a picture-word verification task in which they indicated whether a picture of an animate/inanimate object matched a subsequent word produced by an actress in a video. Stimuli were either …

Verb Tense Production Differences Across Various Discourse Tasks In People With Fluent And Nonfluent Aphasia, Madeline Ann Zurbrugg

Honors Theses

Background: Fluent and nonfluent aphasia are both seen to exhibit varying degrees of morphosyntactic difficulties, with particular difficulties in verb tense production. There is disagreement regarding why tense is particularly impaired, which type of aphasia is more impaired and why, and whether some tense forms are more impaired than others. There is also evidence that language elicitation tasks affect language production measures because they require different linguistic and cognitive processes. This is likely also true for verb tense production. To date, no studies have examined discourse elicitation task effect on verb tense production in both fluent and nonfluent aphasia. The …

The Relationship Between Communicative Confidence And Identity In Everyday Life For People With Aphasia, Karina Escobar

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

Aphasia is primarily a neurological language disorder, which can also affect cognition, attention, and executive functioning skills. In recent years, researcher has taken an interest in understanding quality of life for people with aphasia, specifically communicative confidence, social relationships, and identity. The aim of this study was to determine how communicative confidence and social relationships affect a person’s identity, as well as the importance of therapy groups. We designed and used confidence and independence survey scales pre-aphasia, post-aphasia but before attending aphasia therapy groups, and post-aphasia and after having attended aphasia therapy groups. We also asked clarifying questions based on …

Students' Understanding Of Self-Management In Aphasia Treatment, Maryse Azer

Honors College Theses

Aphasia is a neurogenic language disorder caused by damage to the language areas of the brain in the left hemisphere, resulting in speech and language impairments. People with aphasia (PWA) often receive services from speech-language pathologists (SLPs) who provide screening, assessment, diagnosis, and treatment to address communication deficits. Aphasia is a chronic condition and PWA experience symptoms throughout their lives. Healthcare costs related to aphasia account for $46 billion annually. Provider shortages, lack of transportation, insurance constraints, and travel expenses can leave PWA without adequate care. One possible solution to the costs and access issues is the implementation of self-management …

Publications and Research

Studies on the efficacy of language treatment for multilingual people with post-stroke aphasia and its generalization to untreated languages have produced mixed results. We conducted a systematic review and a meta- analysis to examine within- and cross-language treatment effects and the variables that affect them. We searched PubMed, PsycINFO, CINAHL, and Google Scholar (February 2020; January 2023), identifying 40 studies reporting on 1573 effect sizes from 85 individuals. We synthesized effect sizes for treatment outcomes using a multi-level model to correct for multiple observations from the same individuals. The results showed significant treatment effects, with robust within-language treatment effects and …

Precision Rehabilitation For Aphasia By Patient Age, Sex, Aphasia Severity, And Time Since Stroke? A Prespecified, Systematic Review-Based, Individual Participant Data, Network, Subgroup Meta-Analysis, Release Collaborators, Jacqueline Hinckley

HPD Articles

BACKGROUND: Stroke rehabilitation interventions are routinely personalized to address individuals' needs, goals, and challenges based on evidence from aggregated randomized controlled trials (RCT) data and meta-syntheses. Individual participant data (IPD) meta-analyses may better inform the development of precision rehabilitation approaches, quantifying treatment responses while adjusting for confounders and reducing ecological bias. AIM: We explored associations between speech and language therapy (SLT) interventions frequency (days/week), intensity (h/week), and dosage (total SLT-hours) and language outcomes for different age, sex, aphasia severity, and chronicity subgroups by undertaking prespecified subgroup network meta-analyses of the RELEASE database. METHODS: MEDLINE, EMBASE, and trial registrations were systematically …

Brain Age Predicts Long-Term Recovery In Post-Stroke Aphasia, Sigfus Kristinsson, Natalie Busby, Christopher Rorden, Roger Newman-Norlund, Dirk B. Den Ouden, Sigridur Magnusdottir, Haukur Hjaltason, Helga Thors, Argye E. Hillis, Olafur Kjartansson, Leonardo Bonilha, Julius Fridriksson

Communication Sciences and Disorders Faculty Articles and Research

The association between age and language recovery in stroke remains unclear. Here, we used neuroimaging data to estimate brain age, a measure of structural integrity, and examined the extent to which brain age at stroke onset is associated with (i) cross-sectional language performance, and (ii) longitudinal recovery of language function, beyond chronological age alone. A total of 49 participants (age: 65.2 ± 12.2 years, 25 female) underwent routine clinical neuroimaging (T1) and a bedside evaluation of language performance (Bedside Evaluation Screening Test-2) at onset of left hemisphere stroke. Brain age was estimated from enantiomorphically reconstructed brain scans using a machine …
