Filter by:This monocentric methodological study aims at optimizing advanced MR sequences for image quality (reduced artefacts, signal to noise ratio, acquisition time, stability of quantitative measurements) on a new MR unit dedicated to research in clinical and cognitive neuroscience.
The aim of this study was to determine the differences in hemodynamics between different positions in patients undergoing ultra-early reperfusion therapy.
The physical and social effects of exercise programs and daily exercise have already been demonstrated in stroke. However, stroke survivors have shown a passive attitude towards the exercise program and there was little guideline and experience of the stroke exercise program in the community. Therefore, the study provides patients with an adequate guide to a complex exercise program after discharge based on the medical records.
Research shows that exercising at home can improve arm and hand movement after a stroke. Unfortunately, it can be hard to exercise enough to make a difference in arm and hand movement after stroke. In this study, the investigators will try to determine things that make it easy or hard for Veterans to exercise their arm and hand after a stroke. In this study, the investigators will recruit Veteran stroke survivors who have difficulty using their arm and hand after a stroke. First, the investigators will administer surveys and questionnaires to get Veteran stroke survivors' perspectives on their self-confidence, mood, sleep, and more. Then, the investigators will ask them to track their home exercise using a wearable movement tracker (like a smart watch). Then, Veteran stroke survivors will meet with a researcher to talk about their experience doing home exercise and why they think it was easy or hard to do.
Upper limb impairment is present in more than 85% of people with stroke, which greatly affect the quality of life, social participation, and performance of daily activities of people with stroke. Previous study also revealed that 53.4% of people after stroke experienced cognitive impairment. Different cognitive domains might be affected following stroke, such as attention, memory, language, and orientation, and the problems with memory are often prominent. Yet, there is no effective treatment for the post-stroke cognitive impairment. Transcutaneous electrical nerve stimulation (TENS) applied on thoracic region and transcutaneous vagus nerve stimulation (tVNS) are simple and non-invasive treatment to improve upper limb motor function and cognitive function. However, no existing studies have explored on the effects of TENS and tVNS on cognitive function in people with stroke. Therefore, the purpose of this study is to evaluate the effectiveness of TENS on improving upper limb function and cognitive function in people with chronic stroke. Also, this study will investigate the cortical response of people with stroke during TENS by using EEG power spectrum analysis.
The main goal of this study is to reorganize how stroke educational materials are given to patients from written delivery of information to using verbal delivery of information. Another goal is to compare post stroke behavior and medication compliance in participants receiving the new verbal model of stroke education vs. those receiving the current written stroke education. The main question[s] it aims to answer are: - Does the current delivery of stroke education provide the necessary knowledge base for patients who have suffered a stroke as measured by a stroke questionnaire? - Does verbal education provide better understanding for patients post-stroke? - Are patients more likely to be compliant with medications and followup visits with their medical team after receiving verbal education? Participants will receive a health literacy assessment and based on their scores will be categorized into a high health literacy (HHL) or low health literacy group (LHL). Individuals in both literacy groups will be randomized into receiving verbal or written stroke education. All participants will be tested with the stroke knowledge assessment to measure learning after education. Researchers will compare written to verbal education to see if verbal results in more stroke education and compliance.
To investigate the performance of enhanced computed tomography (CT) or magnetic resonance (MR) imaging by deep learning relative to conventional CT or MR imaging in brain stroke and vascular neurology. We expect that the deep enhanced imaging method can shorten the time stay in the imaging session of stroke patients, optimize the overall imaging quality and improve the patients' care in imaging session.
It was planned to examine the effects of robot-assisted walking training supported by virtual reality on cognitive functions, quality of life and activities of daily living in individuals with subacute stroke. In this context, only conventional physiotherapy was applied to one group, while the other group was given exercises with Lokomat in addition to conventional physiotherapy.
The purpose of this study is to investigate whether Oxford Cognitive Screen (OCS) can be used as a predictive tool during hospital admission in younger (<65 years) stroke patients, i.e. whether OCS is able to predict the level of cognitive functioning in these patients at 3- and 9-months post-stroke. Secondarily the investigators also want to examine the relationship between OCS scores and the patients' self-report regarding general level of functioning, and if there is a significant development in cognitive level over time by comparing OCS-scores at the different time points. The investigators predict that: a) Baseline OCS-score collected in the sub-acute phase during hospital admission will be helpful in predicting future level of cognitive functioning and level of general functioning: a low score at baseline will be associated with a relatively low score on the supplementary cognitive tests at 3- and 9-months post-stroke and a lower level of general functioning, and vice versa. B) Adding background information to the baseline data of the patients will improve the prediction regarding the future cognitive and general level of functioning. C) At 3- and 9-months post stroke we expect there to be a correlation between OCS-score and the patient's self-report of general functioning, where a low score on OCS will equal self-reports of low general functioning. D) The investigators expect to see significant differences in OCS-scores at different time points indicative of cognitive remission.
Consequences of stroke are manyfold but all of them are important factors on the long-term outcomes of rehabilitation, becoming an important health problem with requires health strategies with advanced age. High intensity interval training (HIIT) is an efficient training protocol used in cardiac rehabilitation programs, but owing to the inter-individual variability in physiological responses to training associated to cardiovascular diseases, the exercise dose received by each patient should be closely controlled and individualized to ensure the safety and efficiency of the exercise program. The heart rate variability (HRV) is actually being used for this purpose, as it is closely linked to de parasympathetic nervous system activation. In this way, higher scores in HRV are associated with a good cardiovascular adaptation. The objective of this protocol is to determine the effect of HIIT compared with HRV-guided training on cardiorespiratory fitness, heart rate variability, functional parameters, body composition, quality of life, inflammatory markers, cognitive function, and feasibility, safety and adherence in patients after stroke undertaking an 8-week cardiac rehabilitation program. This will be a cluster-randomized controlled protocol in which patients after stroke will be assigned to an HRV-based training group (HRV-G) or a HIIT-based training group (HIIT-G). HIIT-G will train according to a predefined training program. HRV-G training will depend on the patients' daily HRV. The peak oxygen uptake (VO2peak), endothelial and work parameters, the heart rate variability, the functional parameters, the relative weight and body fat distribution, the quality of life, the inflammatory markers, the cognitive function, and the exercise adherence, feasibility and safety will be considered as the outcomes. It is expected that this HRV-guided training protocol will improve functional performance in the patients after stroke, being more safe, feasible and generating more adherence than HIIT, providing a better strategy to optimize the cardiac rehabilitation interventions.
