Development Of The Tagalog Version Of The Western Aphasia Battery-Revised, Carmina Ozaeta

Electronic Theses and Dissertations

There has been limited research done in the Philippines in the area of aphasia, a frequent concomitant symptom of strokes and presents as impairment in any area of the input and output of language. Diagnosis is generally conducted by clinicians based on sites of lesion of speakers with aphasia and clinical observations of language symptoms and unpublished translation of the WAB. The lack of relevant research and formal assessment tools in the Philippines motivated this current study. The development of this type of assessment battery for the Tagalog (pronounced /təˈɡɑːlɒɡ/ in English) speaking population will provide a means for differential …

A Single-Subject Study Examining The Effects Of A Behavioral Intervention For Verbal Recurrent Perserveration, Jenifer Juengling-Sudkamp

LSU Doctoral Dissertations

BACKGROUND: Approximately 1 million people in the United States suffer from aphasia and > 50% of those people may demonstrate recurrent perseverations. No consensus has been forthcoming on whether (1) a therapy that directly confronts clients with imminent pre-articulatory automatisms (the perseverations) or (2) a more typical neuropsychological therapy that eschews any direct confrontation with automatic behaviors works best. PURPOSE: The purpose of this study was to determine the treatment efficacy of a non-confrontational picture naming intervention on naming ability in individuals with aphasia and recurrent perseverations. METHODS: This is a prospective single-subject ABAB multiple baseline design replicated across 3 right-handed …

Comparing The Treatment Effect Of Conversational And Traditional Aphasia Treatments Based On Conversational Outcome Measures, Meghan Collins

LSU Doctoral Dissertations

This prospective Phase I single-subject (ABABA) study repeated across 4 participants with quasi-randomized treatment order investigated the treatment effects of conversation and traditional stimulation treatments on conversational outcomes. Treatment was administered for 10 sessions (2 one-hour weekly sessions) per treatment type. Primary conversational outcomes included 6-minute conversations coded for pragmatic behaviors and percent Correct Information Units (CIUs). Traditional stimulation probes included auditory comprehension, lexical retrieval, and syntax probe performance. Secondary outcome measures represented the domains of the ICF (WHO, 2001) model with the addition of quality of life. These included the Western Aphasia Battery (Kertesz, 2007), the American Speech Language …

Assessing Cortical Electrophysiologic And Behavioral Activity In Individuals With Aphasia And Participants With No Brain Damage Responding To Spoken Sentence Length Messages, Patricia Lara

Open Access Theses & Dissertations

In this study, six individuals with aphasia and twelve participants with no brain damage responded to spoken sentence length messages using a modified version of the Revised Token Test (McNeil & Prescott, 1978) while cortical activation was recorded using event related potentials (ERP). ERP is a non-invasive imaging procedure that measures cortical activation reflected in the electrical activity that is produced at the level of the cortex in response to internal or external stimulus.

Participants were presented with a visual display that provided eight different token arrangements per trial that were displayed on the computer screen. Spoken messages that increased …

Cerebral Perfusion In Chronic Stroke: Implications For Lesion-Symptom Mapping And Functional Mri, Jessica D. Richardson, Julie M. Baker, Paul S. Morgan, Chris Rorden, L. Bonilha, Julius Fridriksson

Faculty Publications

Lesion-symptom mapping studies are based upon the assumption that behavioral impairments are directly related to structural brain damage. Given what is known about the relationship between perfusion deficits and impairment in acute stroke, attributing specific behavioral impairments to localized brain damage leaves room for speculation, as impairments could also reflect abnormal neurovascular function in brain regions that appear structurally intact on traditional CT and MRI scans. Compared to acute stroke, the understanding of cerebral perfusion in chronic stroke is far less clear. Utilizing arterial spin labeling (ASL) MRI, we examined perfusion in 17 patients with chronic left hemisphere stroke. The …

Communicative Competence In Persons With Aphasia: The Impact Of Executive Function, Judy Marie Mikola

Wayne State University Dissertations

The purpose of this study was to examine the relationship between executive function and performance on selected linguistic tasks in persons with aphasia secondary to left frontal lesions.

A group of 15 persons with aphasia (PWA) completed three communication board tasks of varying levels of complexity and structure. The subject's functional use of the picture/word communication board was tested during a Story Retelling task. In addition, the PWA's executive function skills were examined using six nonverbal tests. The PWA group performance scores were compared to that of the neurologically healthy control group.

Results demonstrated that the control group performed significantly …

Neuroimaging And Recovery Of Language In Aphasia, Cynthia K. Thompson, Dirk B. Den Ouden

Faculty Publications

The use of functional neuroimaging techniques has advanced what is known about the neural mechanisms used to support language processing in aphasia resulting from brain damage. This paper highlights recent findings derived from neuroimaging studies focused on neuroplasticity of language networks, the role of the left and right hemispheres in this process, and studies examining how treatment affects the neurobiology of recovery. We point out variability across studies as well as factors related to this variability, and we emphasize challenges that remain for research.

Repetition Priming And Anomia: An Investigation Of Stimulus Dosage, Catherine A. Off

Speech, Language, Hearing, and Occupational Sciences Faculty Publications

In a recent review of anomia management, Maher & Raymer reported that 30% of aphasia intervention research from 1946 to 2001 focused on naming; however, "despite this proliferation of case reports and small group studies, there is still no clear agreement on how best to manage these deficits" (Maher & Raymer, 2004, p. 13). The inconsistency of acquisition, maintenance, and generalization effects observed across participants and types of treatment protocols is likely to stem from an inadequate knowledge base about how subject and treatment variables influence learning.

One treatment variable that has received increasing attention over the past two or …

The Investigation Of Treatment Outcomes For Adults With Chronic Brain Injury Following Intensive Multidisciplinary Treatment, Donna Mineo Fitzgerald-Dejean

LSU Doctoral Dissertations

Although communication sciences and disorders (COMD) research supports intensive treatment for individuals with chronic brain injury, funding to provide these services is limited. This study explored the use of interdepartmental university resources to provide an intensive, multidisciplinary chronic brain injury program. Methodologically, treatment regimes were designed with clinical faculty as practicum experiences for COMD master’s degree students. Subjects with a single onset head injury or cerebral vascular accident greater than one year were recruited to participate in the Intensive Treatment, Weekly Treatment or Control Groups. Pre, Post, and Post-Post Testing were used to measure cognitive-linguistic, quality of life and physical …

Examining The Effects Of Non-Intensive Therapy On Word Retrieval, Apraxic Errors And Quality Of Life Following Intensive Therapy, Erin Lofton Cain

LSU Master's Theses

The purpose of this study was to determine if given a period of intensive aphasia therapy a patient diagnosed with aphasia and an accompanying apraxia would maintain, gain, or lose skills during non-intensive therapy. A literature review revealed that intensive therapy has been shown to increase a patient's skill level in various areas. However, very little research was found that focused on how these patients' perform when reintroduced to typical aphasia therapy. This study proposed three specific questions: if the participant would retain her current level of word retrieval functioning evident after intensive therapy, if the participant would retain her …

Expectation In Visual Symbolic Processing Of Environmental Symbols In People With Fluent Aphasia, Amanda Stead

LSU Master's Theses

The purpose of this study was to examine aspects of visual symbolic processing in those individuals with fluent aphasia, and how it compares to that of their lexical ability. Two groups of participants were examined: a group with fluent aphasia, and a group of non-neurologically damaged controls. Participants were administered four computer based expectation tasks, two of which were symbolic, and two which were lexical. Each task contained a simple and a complex level. Participants were required to determine if the final stimulus, within a set of four, was congruent or incongruent. The measures taken included both reaction time and …

Expectation In Auditory Processing Of Environmental Sounds In People With Fluent Aphasia, Meghan Evelyn Collins

LSU Master's Theses

The purpose of this study was to examine the integrity of the nonverbal auditory system in subjects with fluent aphasia, and determine the relative preservation of the nonverbal auditory system in comparison to the lexical system. This was attempted through the task of expectation, a high level processing skill. Two groups of participants were examined: a group with fluent aphasia, and a group of non-neurologically damaged individuals. Participants were administered two nonverbal auditory conditions devoid of lexical information, a simple condition and a complex condition in which they were required to determine if the last sound heard in a sequence …

Phonetic And Acoustic Analyses Of Two New Cases Of Foreign Accent Syndrome, Rosalie Perkins

Electronic Theses and Dissertations

This study presents detailed phonetic and acoustic analyses of the speech characteristics of two new cases of Foreign Accent Syndrome (FAS). Participants include a 48-year-old female who began speaking with an "Eastern European" accent following a traumatic brain injury, and a 45-year-old male who presented with a "British" accent following a subcortical cerebral vascular accident (CVA). Identical samples of the participants' pre- and post-morbid speech were obtained, thus affording a new level of control in the study of Foreign Accent Syndrome. The speech tasks consisted of oral readings of the Grandfather Passage and 18 real words comprised of the stop …

Effects Of Gesture+Verbal Treatment For Noun And Verb Retrieval In Aphasia, Anastasia M. Raymer, Floris Singletary, Amy Rodriguez, Maribel Ciampitti, Kenneth M. Heilman, Leslie J. Gonzalez Rothi

Communication Disorders & Special Education Faculty Publications

Links between verbs and gesture knowledge suggest that verb retrieval may be particularly amenable to gesture+verbal training (GVT) in aphasia compared to noun retrieval. This study examines effects of GVT for noun and verb retrieval in nine individuals with aphasia subsequent to left hemisphere stroke. Participants presented an array of noun and verb retrieval deficits, including impairments of semantic and/or phonologic processing. In a single-participant experimental design, we investigated effects of GVT for noun and verb retrieval in two counterbalanced treatment phases. Effects were evaluated in spoken naming and gesture production to pictured objects and actions. Spoken naming improvements associated …

Word-Retrieval Treatment In Aphasia: Effects Of Sentence Context, Anastasia Raymer, Francine Kohen

Communication Disorders & Special Education Faculty Publications

Word-retrieval treatment studies in aphasia have reported the greatest influences on picture naming for trained words. To increase treatment effects to untrained words and sentence contexts, we investigated a sentence-reading treatment hierarchy that moves from errorless to generative production of sentences incorporating target nouns and verbs. In an individual with nonfluent aphasia, treatment resulted in improved picture naming for nouns and verbs and generalized increases in numbers of grammatical sentences and content words following noun therapy. A second individual with fluent aphasia improved little in picture-naming and sentence-generation tasks for both nouns and verbs. This sentence-based word-retrieval training, in which …

The Effects Of A Multimodality Approach On Sentence Production Using Response Elaboration Training With A Reading Component On Aphasic Patients., Sara E. Mccarthy

Electronic Theses and Dissertations

The effects of a multimodality treatment were investigated using a single subject experimental design across behaviors in two patients with different severity levels of Broca's aphasia. We hypothesized that Response Elaboration Training and an oral reading task would improve accuracy of sentence production, information content, and mean length of utterance. Results indicated that this treatment approach elicited significant improvement in the accuracy of sentence production and information content in the participant with very mild Broca's aphasia. Furthermore, the participant with severe Broca's aphasia demonstrated a very significant improvement in information content and mean length of utterance. The improvements support the …

Treatment Of Adynamia In Aphasia, Anastasia M. Raymer

Communication Disorders & Special Education Faculty Publications

Transcortical motor aphasia (TCMA) is an acquired impairment of language expression that occurs following neurologic damage that affects left frontal cortex and spares perisylvian regions. In some individuals with TCMA, verbal expression is rendered nonfluent due to difficulty spontaneously initiating and elaborating upon verbal messages. Nonfluency arises from impaired activation of intended messages and inhibition of competing verbal expressions. This impairment of the intentional aspects of language expression can be termed 'adynamia.' Because adynamic forms of TCMA occur infrequently, few systematic treatment investigations have been reported for this condition. Behavioral treatments have been proposed to engage intact frontal regions to …

Word Retrieval Behaviors Of Aphasic Adults In Conversational Speech : A Preliminary Study, Priscilla Jane Blake

Dissertations and Theses

Word retrieval difficulties are experienced by almost all aphasic adults. Consequently, these problems receive a substantial amount of attention in aphasia treatment. Because of the methodological difficulties, few studies have examined WRBs in conversational speech, focusing instead on confrontational naming tasks in which the client is asked to retrieve a specific word. These studies have left unanswered questions about the WRB processes.

The purposes of this study were to: (1) develop profiles of WRB for moderately impaired aphasic adult clients and examine these profiles for evidence that reflects the level of breakdown in the word retrieval process, and (2) determine …

Sixteen subjects with a CVA to the right hemisphere of the brain were compared to an equal number of left hemisphere damaged subjects. Subjects were selected after they had demonstrated an adequate level of functioning on the Short Porch Index of Communicative Ability (SPICA), a test which measures communicative efficiency, to perform the tasks required in this study. All subjects were administered the revised version of the Nelson Reading Skills Test (NRST). …

Coverbal Behavior Of Aphasic And Right Hemisphere Damaged Subjects In Conversation, Jill Duvall

Dissertations and Theses

The frequency and duration of six coverbal behaviors were examined in two experimental groups and one control group. Conversational samples of ten aphasic subjects, ten right hemisphere damaged (RHD) subjects, and ten matched, non-brain damaged (NBD) control subjects were scored for frequency and duration of eye contact, head nod, head shake, head tilt, smile and eyebrow raise. Only the frequency of smile was found to differ significantly; the RHD subjects smiled less often than either of the other two groups.

A Comparison Of Motoric And Linguistic Features In Graphic Samples Of Fluent And Nonfluent Aphasic Persons Over Three Time Intervals, Babette Fisher

Dissertations and Theses

University of the Pacific Theses and Dissertations

The purpose of this study was to determine whether correlations existed between a measure of linguistic complexity in spontaneous speech and performance on the four verbal subtests of the PICA.

The Effects Of Morning And Afternoon Scheduling On The Clinical Performance Of Severe Aphasic Adults, Judith Ann Fisher

Dissertations and Theses

Concern regarding variables which influence the performance of aphasic adults has been demonstrated in the literature. Marshall et al. (1978) found that one such variable, scheduling of intervention, influenced significantly the test performance of their subjects. They determined that the aphasic subjects performed better in the morning than in the afternoon. The purpose of the present study was to determine if performance of severe aphasic adults on easy and difficult, single-word picture-identification tasks, presented in a clinically reinforcing manner, is differentially affected by morning and afternoon scheduling.

The questions posed in this investigation were: 1) Does morning versus afternoon scheduling …

Twenty subjects from the greater Portland metropolitan area were selected to be included in this study. The ages or the subjects ranged from forty-two through sixty-five years with a mean of fifty-four years.

The test material consisted of two paragraphs controlled for fourth grade grammar and vocabulary and two paragraphs controlled for sixth grade grammar and vocabulary. A normally written and a telegraphically written paragraph were used for each of the four paragraphs for …

Effects Of Verbal And Pantomime Stimulus Input On The Short Term Sequential Recall Of Aphasic Adults, Lauryl Suzanne Ivers Grotting

Dissertations and Theses

The question posed in this investigation was: Which stimulus input mode, verbal, pantomime, or combined verbal and pantomime, is more effective in facilitating short term sequential recall of language material with aphasic adults?

Effects Of Semantic Associational Strength And Verbal Sequence Length On The Auditory Comprehension Of Aphasic Adults, Laurel J. Brown

Dissertations and Theses

The purpose of this study was to investigate the effects of semantic associational strength (SAS) upon adult aphasics' auditory comprehension abilities. Twenty-eight adult aphasics (25 males and 3 females) and 12 normal control subjects were presented three experimental tasks, each containing 45 items. Experimental task 1 contained single word picture sets of high SAS, moderate SAS, and low SAS words. Experimental task 2 contained two word picture sets of high, moderate, and low SAS words, and experimental task 3 contained three word picture sets of high, moderate, and low SAS words. Subjects heard one, two, and three word verbal sequences …

Childhood Aphasia, Beatrice O. L. Williams

Graduate Student Research Papers

Childhood Aphasia is not to be confused with mental retardation, deafness, hard of hearing nor the socially and emotionally disturbed, although the symptomology is comparative in nature. Only through differential diagnosis, involving the services and cooperation of specialists in these various fields is it properly diagnosed.
