View clinical trials related to Aphasia, Acquired.
Filter by:Aphasia in brain-damaged adult patients refers "to the more or less complete loss of the ability to use language" resulting from acquired brain damage, typically of the left hemisphere. The defective spoken output of persons with aphasia (PWA) has anomia as a main clinical manifestation. Improving anomia is a main goal of any language treatment. The present randomized controlled study assessed the effectiveness of a novel, two-week, rehabilitation protocol (PHOLEXSEM), focused on PHonological, SEmantic, and LExical deficits, aiming at improving lexical retrieval, and, generally, spoken output. The effects of the PHOLEXSEM treatment were compared to those of a control treatment, i.e., a Promoting Aphasics Communicative Effectiveness (PACE) protocol. Finally, we studied the effects of age, education, disease duration, brain lesion volume, and functional independence (Functional Idependence Measure, FIM) on the treatment-induced linguistic improvements.
The proposed research is relevant to public health because stroke is a leading cause of long-term disability among older adults and communication impairments resulting from stroke have a significant negative impact on quality of life. By seeking to better understand post-stroke aphasia, this project lays the groundwork for development of new interventions, and aligns with NIDCD's priority areas 1 (understanding normal function), 2 (understanding diseases), and 3 (improving diagnosis, treatment, and prevention).
The goal of this clinical trial is to establish the feasibility and fidelity of a high-intensity exercise program for individuals with post-stroke aphasia. The main questions it aims to answer are: - Is it feasible for stroke survivors with aphasia to participate in a long in-person physical exercise program? - Does participation in a physical exercise program lead to physical fitness, cognitive, language and/or psychological changes? Participants can take part in two different physical exercise interventions: - Low intensity intervention (control intervention); - High-intensity physical exercise intervention (target intervention).
The goal of this study is to see if transcranial alternating current stimulation (tACS) can be used to enhance language abilities in people with post-stroke aphasia. Participants will receive real and sham tACS in conjunction with various language tests. Researchers will compare the post-stroke aphasia group with aged matched controls to see if brain response to tACS differs between groups.
Background and aim There is a growing awareness that people with aphasia (language problems) after a stroke often have difficulties with their short-term memory (STM). As a result, the explanation underlying aphasia has recently been seen as a language processing disorder, where multiple cognitive processes interact. To evaluate the cognitive processes underlying aphasia, there is a need for reliable and valid assessment tools. However, the quality of tests usually used to assess STM problems in aphasia patients is questioned because they are not specifically designed to be used in aphasia patients. This raises some concern, as impairments of STM can be predictive for the recovery and rehabilitation of aphasia patients. As an important exception, a recent study has developed a new English evaluation tool (i.e., The Temple Assessment of Language and (Verbal) Short-term Memory in Aphasia; TALSA) that examines language and STM aspects specifically developed for persons with aphasia. However, the existence of a Dutch evaluation tool specifically designed to assess language and STM problems in people with aphasia after a stroke is lacking. Therefore, the aim of the current study is to develop a Dutch clinical version of the TALSA battery that may lead to better diagnosis and treatment of STM problems in persons with aphasia. The development of the test focuses on its clinical feasibility (e.g. test duration, difficulty of the items and response modality). Pilot testing of the Dutch STM assessment instrument in the clinical and healthy population is very important to adapt the test where necessary. In addition, the quality of the test should also be carefully evaluated. Method The first step towards the development of a Dutch STM assessment instrument is the careful selection of the most crucial subtests of the original TALSA battery. Not all subtests will be selected due to the long testing time of the TALSA battery, and as mentioned earlier, the Dutch STM assessment tool focuses on clinical feasibility of the test. The second step is pilot testing the Dutch STM assessment instrument in persons with aphasia and healthy persons. Persons with aphasia will be recruited at the Stroke unit of Ghent University Hospital. All eligible patients will be asked to provide written informed consent to participate in this study. Three tests will be administered, namely the Oxford Cognitive Screen, the Token Test and the Dutch STM assessment tool. It is important that these tests are taken on the same day or on two consecutive days, depending on the circumstances (e.g. fatigue). The Token Test and Oxford Cognitive Screen provide a picture of the patient's cognitive profile. Throughout the process of pilot testing, the Dutch STM assessment tool will be adapted and improved where necessary. In order to verify or adjust the difficulty of the items, it is crucial that the STM assessment instrument is also tested on a small number of healthy control subjects (recruited via social media platforms).
The objective of this research is to experimentally delineate the direct effect of speech entrainment practice on independent speech production and identify practice conditions that enhance treatment benefits. The primary outcome measure (Correct Information Units per minute) tallies informativeness and efficiency of independent speech in treated stories.
The goal of this intervention study is to investigate the effects of immersive virtual reality in rehabilitation of language and communication of individuals with post-stroke aphasia. The main research questions are: 1. Is VR-based script training a feasible treatment to Cantonese-speaking PWA? 2. Will VR-based script training, when compared to conventional script training, better enhance treatment outcomes in functional communication of PWA? Participants will be assessed before, in the middle of, immediately after treatment and 8-week post treatment in terms of their performance on: 1. Accuracy and time for producing trained scripts. 2. Accuracy and time for producing un-trained scripts 3. Standardized aphasia test on severity of language impairment 4. Standardized aphasia test on functional communication The participants will be randomly allocated to receive one of the treatment: 1. Virtual reality-based computerized script training; or 2. Computerized script training without virtual reality Researchers will compare the treatment outcomes of the two treatment conditions and see if treatment with virtual reality would better promote outcomes when compared to training without virtual reality.
In the planned study, clinical and electrophysiological features of aphasia recovery in stroke patients are investigated.
The purpose of the study is to examine the impact of group participation on adults with aphasia. Participants will complete a standard pre-and post-assessment of language abilities (speech, comprehension, reading, and/or writing). Then participants will attend 90-minute weekly reading group sessions during an academic semester.
The purpose of this study is to test the feasibility and acceptability of an online exercise program for community-dwelling individuals with aphasia, a language disorder resulting from brain damage. Physical activity, language, cognitive, and quality of life outcomes will be collected to assess potential effectiveness.
