Filter by:The purpose of this study is to determine whether the effect of treatment for acquired speech impairment can be enhanced by combining effective behavioral treatment with non-invasive brain stimulation. Transcranial direct current stimulation (tDCS), which delivers low-intensity current to the scalp, and is a safe and well-tolerated approach that poses a non-significant risk to participants. tDCS provides low intensity neural stimulation which has been shown to facilitate motor learning in other domains of stroke rehabilitation such as arm motor learning but the potential to enhance speech motor learning has not been explored. This will be examined with a series of single-case experimental designs.
This protocol is designed to enable access to intravenous infusions of banked umbilical cord blood (CB), that is thawed and not more than minimally manipulated, for children with various brain disorders. Children with cerebral palsy, congenital hydrocephalus, apraxia, stroke, hypoxic brain injury and related conditions will be eligible if they have normal immune function and do not qualify for, have previously participated in, or are unable to participate in an active cell therapy clinical trial at Duke Medicine. For the purpose of this protocol the term children refers to patients less than 26 years of age. Cord blood is administered as a cellular infusion without prior treatment with chemotherapy or immunosuppression. The mechanism of action is through paracrine signaling of cord blood monocytes inducing endogenous cells to repair existing damage.
The purpose of this study is to identify and distinguish two different types of Progressive Apraxia of Speech through clinical imaging and testing.
The purpose of the proposed research is to examine the effects of two treatment approaches on speech production involving speakers with chronic apraxia of speech (AOS) and aphasia. The planned investigation is designed to examine the acquisition, maintenance and generalization effects of each treatment. One approach, electropalatography (EPG) uses visual biofeedback in conjunction with articulatory-kinematic treatment and the other approach, sound production treatment (SPT) is one of the most systematically studied articulatory-kinematic treatments for AOS.
A growing neurorehabilitation literature suggests that intense treatment may be desired to maximize the effects of therapy following neurologic injury. This investigation is designed to facilitate the development of efficacious, clinically applicable treatment for acquired apraxia of speech by examining the effects of intensity of treatment (e.g., 9 hours per week vs. 3 hours per week, while holding total number of sessions constant) with a group of speakers who have chronic apraxia of speech and aphasia.
Impaired speech production is a major obstacle to full participation in life roles by stroke survivors with aphasia and apraxia of speech. The proposed study will demonstrate the short-term effects of auditory masking on speech disfluencies and identify individual factors that predict a positive response, enabling future work to develop auditory masking as a treatment adjuvant targeting long-term improvement in speech. Providing an additional treatment option for adults with aphasia and apraxia of speech will have the clear benefit of improving quality of life and allowing individuals to participate more actively in their health care decisions through improved communication.
In order to determine if speech-language therapy has positive effect, reliable measurement tools are required to document outcomes. Currently, there is very limited information concerning the measurement of changes in speech production as a result of treatment for acquired apraxia of speech and aphasia. This study will obtain information concerning the reliability of several speech production measures over time. Thirty persons with chronic aphasia and apraxia of speech will be asked to provide speech samples in response to commonly used assessment tools on three sampling occasions so that the stability of measurements may be examined. After establishment of appropriate outcome measures, a small, pilot treatment study will be conducted with four participants. The participants will receive a new treatment for aphasia and acquired apraxia of speech and outcomes will be measured relative to speech and language production.
The study is designed to determine the relationship between structural and functional changes in the brain on imaging and progression of speech and language, neurological and neuropsychological features in patients with neurodegenerative apraxia of speech (AOS).
The study is designed to determine whether there are clinical features that can be used as biomarkers to predict whether underlying Alzheimer's pathology is the cause of a speech and language based dementia. The primary hypothesis is that the proportion of patients who test positive for beta-amyloid deposition will vary across different speech and language based dementias.
This study was designed to examine the effects of speech therapy on ability to produce speech sounds in persons with acquired apraxia of speech.
