Filter by:This study will assess the effects of transcranial alternating current stimulation (tACS) on language recovery after stroke.
The goal of this interventional study is to investigate the therapeutic efficacy of non-invasive vagus nerve stimulation on upper limb function in chronic stroke patients . The main question is: •Is there a significant effect of non-invasive vagal nerve stimulation on upper limb motor function in stroke patients? Participants will be assigned into two groups. They will receive 12 sessions of true or sham transcutaneous auricular vagus nerve stimulation for 30 minutes immediately followed by 30 minutes of selected physical therapy program, three sessions per week for four weeks.
This study is aiming to evaluate the safety and efficacy of SeQuent® Please CIS in the endovascular treatment of symptomatic intracranial atherosclerotic stenosis and restenosis after interventional therapy.
Atrial fibrillation is a cardiac arrhythmia most often originating in the left atrium, causing anarchic electrical activity and thus a loss of atrial contraction. This increases the risk of stroke through clot formation in the atrium, but also of heart failure. Atrial fibrillation is a major cause of stroke, accounting for more than 25% of all strokes. In addition, a quarter of ischemic strokes remain without an obvious cause at the end of hospitalization, and it is recommended that atrial fibrillation be detected intensively with long-term heart rhythm recording. Implantable loop recorders can detect 30% of atrial fibrillation cases over the 3-year battery life of these devices, after a stroke of undetermined origin. However, these devices require a small operation to implant them under the skin, and they are expensive. The hypothesis of this study is that MRI imaging of the left atrium would enable better selection of patients to receive an implantable loop recorder. MRI can quantify the proportion of the left atrium with scar tissue, which is likely to favour the onset of atrial fibrillation. If the results confirm this hypothesis, the number of patients requiring an implantable loop recorder could be reduced, and perhaps an anticoagulation strategy based on MRI data could be introduced. In addition to the usual follow-up by cardiologists and neurologists, participation in this study involves a cardiac MRI (with contrast agent) within 3 months of the stroke.
The purpose of this research is to better understand the impact of cortically-induced blindness (CB) and the compensatory strategies subjects with this condition may develop on naturalistic behaviors, specifically, driving. Using a novel Virtual Reality (VR) program, the researchers will gather data on steering behavior in a variety of simulated naturalistic environments. Through the combined use of computer vision, deep learning, and gaze-contingent manipulations of the visual field, this work will test the central hypothesis that changes to visually guided steering behaviors in CB are a consequence of changes to the visual sampling and processing of task-related motion information (i.e., optic flow).
This clinical study aims to confirm the characteristics of the functional ansiotropy value according to the individual characteristics of stroke patients by taking brain diffusion tensor images for stroke patients and using the MRI. To compare hematologic indicators and neurological function levels of stroke patients at the time of imaging examination with brain diffusion tensor imaging indicators.
Postoperative delirium (POD) is common in elderly patients recovering from surgery and anesthesia. POD has adverse effects on early and long-term prognosis. The incidence of POD increases with age and patients with preoperative cognitive changes or coexisting diseases. The bispectral index (BIS) is an electroencephalographic measurement commonly used to monitor the depth of anesthesia. Low intraoperative BIS value (BIS<40) and prolonged duration of low BIS value maybe risk factors of POD. A small sub-study of BALANCED Anaesthesia Study demonstrated a protective effect of targeting a BIS of 50 to reduce POD compared with a BIS of 35. The stability of BIS during general anesthesia may affect the risk of POD in elderly patients. Therefore, it is very important to maintain a stable BIS value as much as possible during general anesthesia surgery, and a general anesthetic with good BIS stability is even more needed in clinical practice. Cyclopofol is a new type of anesthetic/sedative that reportedly provides good efficacy and safety. Cyclopofol has a more stable effect on BIS, so whether the use of cyclopofol in elderly patients undergoing orthopedic surgery can reduce the occurrence of POD, improve prognosis, and exert a brain protective effect will be of great importance and clinical research value.
The proposed project is a multicentre prospective observational clinical research focused on refining multimodal computer tomography (CT) diagnostics in stroke mimics. The main aim is to accurately identify SM in order to minimize the risk of receiving inappropriate treatment and possible development of complications, which can have a negative impact on the patient´s health. The project includes an analysis of pharmacoeconomic parameters. It will examine saved costs in the case of non-administration of unindicated treatment and it will compare the number of adverse events related to the administration of unindicated treatment in patients diagnosed with SM.
The purpose of this study is to evaluate the efficacy and safety of early tirofiban administration in patients undergoing IVT
Falls are the most common cause of injuries and hospitalization for elderly people and can lead to a significant loss of independence. Even in the absence of serious injury, falls may lead seniors to restrict their activities outside of the home for fear of falling again.Tinetti's Falls Efficacy Scale (FES) is the most widely used measure of self-efficacy in studies on falls prevention. Mary E. Tinetti developed this scale to measure the fear of falling. The 10item scale was developed to assess confidence in performing daily activities without falling. Items are rated from 1 ¼ extreme confidence to 10 ¼ no confidence at all. The FES scale has been reported to have excellent internal reliability (Cronbach's alpha ranged between 0.89 and 0.99), with all items loading on a single factor.Test-retest reliability has been reported to be good (ranged from r ¼ 0.71 - 0.90).Criterion validity has been demonstrated by significant associations between FES scores and difficulty getting up after a fall, measures of balance and gait, and activity avoidance. In predictor studies, low FES scores were associated with falls restrictions in social functions and activities of daily living (ADL) reduced physical activity and mobility problems. Tinetti's Falls Efficacy Scale has been translated many languages like Chinese, Iranian, Persian etc. But the Urdu translation is not yet available. To measure the fear of falling in stroke patients Tinetti's Falls Efficacy Scale is a reliable and valid scale..In Neuro rehabilitation clinics the most common issue with the patients who come for rehabilitation is Stroke. So, it is highly required to translate valid and reliable instruments like Tinetti's Falls Efficacy Scale in to Urdu language. So, that patients will be able to understand the questionnaire into their native language and will be able to tell about the actual state of their condition.
