Filter by:The long-term goal of this work is to determine if combining a highly intensive, task-specific behavioral language intervention with modulation of the efferent cerebellar-cortical pathway using transcranial direct current stimulation (tDCS) has a positive influence on discourse, verbal fluency and working memory in individuals with non-fluent aphasia after stroke. And if these changes can be related to neuroplastic change in the cerebellar cortical pathway indirectly measured through neurophysiologic changes using spectral electroencephalogram (EEG). The initial phase includes the proposed pilot study data from which will be used to inform a larger clinical trial. The primary aims of this pilot are to 1) determine the effect of combining cerebellar tDCS with constraint-induced language therapy (CILT) on language as measured by a verbal fluency task and discourse task in a small population and 2) identify the tolerance of the intervention and barriers to participation measured by the adverse events questionnaire that will inform the methodology of a larger study. The secondary aims include estimating the size of the treatment effect on 1) delta percentage in F3, F7 and Fp1 compared to F4, F8, and Fp2 using resting state EEG spectral analysis and coherence, 2) working memory as measured by the score on the n-back test and 3) quality of life as measured by the Stroke Aphasia Quality of Life survey tool. The secondary aims will be used to determine the utility of these measures in a larger clinical trial. This is a prospective, crossover study, sham-controlled intervention study with two intervention conditions delivered across 6 intervention sessions (3x/week for two weeks) with a 4-week washout in between. Conditions include: 1) sham cerebellar tDCS and 2) real cerebellar tDCS delivered at 2mA across 20 minutes. Each of these will be delivered during CILT intervention with a licensed, certified speech-language pathologist trained in CILT. Once tDCS stimulation has ended, CILT will continue to be delivered for an additional 25 minutes. Assessments of discourse, verbal fluency, working memory and EEG spectral analysis will be conducted at four timepoints, before and after each intervention phase.
The purpose of this study is the development and validation of an evidence-based mobile application, based on the core premises of Intensive Language-Action Therapy (ILAT) for aphasia, for the training and improvement of chronic aphasia patients administered at the patient's home. It aims at testing the beneficial effect on the linguistic performance (as assessed by the Barcelona and CAL clinical tests) counteracting learned non-use and the usability of the application as a tool for training once discharged from hospital care.
Many stroke survivors experience aphasia, a loss or impairment of language affecting the production or understanding of speech. One common type of aphasia is known as non-fluent aphasia. Patients with non-fluent aphasia have difficulty formulating grammatical sentences, often producing short word fragments despite having a good understanding of what others are trying to communicate to them. Speech language pathologists (SLPs) play a central role rehabilitating persons with aphasia and administer therapy in an attempt to improve communication skills. Despite standard therapy, approximately 50% of individuals who experience aphasia acutely continue to have language deficits more than 6 months post-stroke. In most people, Broca's area is dominant in the left side of the brain. Following a left-sided stroke, the right-sided homologue of Broca's area (the pars triangularis), may adopt language function. Unfortunately, reorganizing language to the right side of the brain seems to be less effective than restoring function to the left hemisphere. Repetitive transcranial magnetic stimulation (rTMS), a form of non-invasive brain stimulation, can be used to suppress activity of specific regions in the right side of the brain to promote recovery of function in the perilesional area. Despite preliminary success in existing studies using rTMS in post-stroke aphasia, there is much work to be done to better understand the mechanisms underlying recovery. Responses to rTMS have been positive, yet heterogenous, which may be related to timing of treatments following stroke.
The investigators will run an at-home usability study of a newly developed speech therapy app called Speech Hero with 10 individuals with Broca's aphasia in the chronic stage of stroke. The Speech Hero app allows users to perform rhythm-based speech exercises at home. For this study participants will be instructed to use Speech Hero for at least 10 hours over a 4-week period.

The present study was conducted to develop the verbal expressive skills management programme (VESMP) to enhance verbal expressive skills of patients with severe Broca aphasia. To determine the efficacy of VESMP in improving the quality of life and level of satisfaction of aphasic stroke patients.Control group received traditional therapy and experimental group received therapy through VESMP programme on their smart phones.
Stroke is the leading cause of adult disability in the United States, and aphasia is common following a stroke to the left hemisphere of the brain. Aphasia therapy can improve aphasia recover; however, very little is known about how different patients respond to different types of treatments. The purpose of this study is to understand how the following factors influence an individual's response to aphasia treatment: 1) biographical factors (e.g., age, education, gender), 2) post-stroke cognitive/linguistic abilities and learning potential, and 3) the location and extent of post-stroke brain damage. We are also interested in understanding the kinds of treatment materials that should be emphasized in speech/language treatment. Overall, the goal of the current research is to inform the clinical management of post-stroke aphasia by identifying factors that can predict how an individual will respond to different treatment methods.
The purpose of this study is to determine whether VR based language rehabilitation scenario based on the core premises of ILAT has a beneficial effect on the linguistic performance (faster retrieval of the target lexicon and general fluency) of Broca's aphasia patients. Furthermore, it aims at testing the effects of cueing (visual and auditory) on word retrieval.
The aim of this study is to assess the safety and clinical efficacy of high or low-frequency repetitive transcranial magnetic stimulation based on brain activation with functional near infrared spectroscopy in poststroke nonfluent aphasia patients.
The purpose of this study is to investigate the effects of treatment for specific language deficits in people with aphasia. In addition to language and cognitive measures, changes in brain function will also be gathered before and after the treatment is administered in order to track any changes resulting from receiving treatment.
