Filter by:The study aims to use novel mobile imaging techniques with high-density electroencephalography (EEG) to quantify cortical processes synchronized to the biomechanics of walking. Here, the study has two aims - the primary aim is to quantify the cortical processes that contribute to gait dysfunction early post-stroke, and the second aim is to determine how cortical processes are mediated by mechanical assistance during early gait training post-stroke. Participants will wear an electroencephalography (EEG) cap to measure brain activity and other non-invasive physiological sensors. Participants will be asked to perform different tasks, such as walking at different speeds and walking with different levels of body weight support.
The goal of this clinical trial is to test whether perfusion CT can be used as a selection tool in stroke patients with a major anterior circulation occlusion, to exclude patients from thrombectomy because of a predicted non-beneficial outcome, when treated within 6 hours of symptom onset. Researchers will compare the experimental group, where mechanical thrombectomy is only performed when prespecified perfusion CT criteria are fulfilled, with the standard of care treatment group, where all patients will receive mechanical thrombectomy, to see if functional independence at 90 days is non-inferior.
Prospective observational multi-center study with the aim to organise and simplify the care pathway through a pragmatic approach to acute stroke imaging powered by cutting edge advances in image processing and artificial intelligence.
ASPHALT is an academic-driven open-label randomized controlled trial of Mobile Stroke Unit (MSU) deployment versus standard care in France, with blinded assessment of efficacy endpoints. 450 patients with confirmed acute ischemic stroke will be recruited over a 3-year period, with 3-month follow-up.
The purpose of this study is to confirm the convergence effectiveness of on acupuncture of the chinese medicine and the tDCS of the western medicine on motor function for patients with acute stroke compared to the control group.
Stroke, main cause of disability in adults, is thought to be the primary cause of swallowing difficulty (dysphagia). Dysphagia is one of the common physical condition among patients with stroke, affecting the large number of stroke patients in the world. It is reported that the occurrence rate of post-stroke dysphagia (PSD) is varies widely, ranging from 19% to 81%, the reason may be associated with the type of stroke, the assessment tools, the timing of the assessment, and so on .Dysphagia is associated with pneumonia, malnutrition, dehydration, increased mortality, and poor long-term outcome. It has been shown that early detection of dysphagia allows for immediate intervention and thereby reduces morbidity, duration of hospitalization, and overall health care costs. Oropharyngeal dysphagia (OD) can have a high impact on the general health of affected patients and can produce two main types of complications in patients with post stroke: (1) those caused by impaired efficacy of swallow, present in 25%-75% of patients, which leads to malnutrition and dehydration and (2) impaired safety of swallow which leads to tracheobronchial aspiration that may cause pneumonia in 50% of cases. Both OD and aspiration are highly prevalent conditions in patients with stroke . Dysphagia is more common in hemorrhagic stroke compared with ischemic stroke, so far, most studies have focused on the latter, presumably due to its higher incidence .The recognition of a brain lesion pattern associated with oropharyngeal dysphagia could help to distinguish those patients in need of more in-depth evaluation and the subsequent adoption of preventive measures. However, it is difficult to predict which patients are susceptible to developing swallowing alterations depending on neuroimaging findings. However, the findings have been inconsistent, mainly due to simplification in the classification of brain injuries into a small number of groups, or to the different methods employed in assessing swallowing function
Prehospital providers encounter patients with suspected stroke frequently. Prehospital providers need tools to help triage large vessel stroke patients to comprehensive stroke centers. This device will identify large vessel stroke to ultimately improve triage decisions and optimize outcomes.
Patients with a clinico-neuroradiological mismatch pattern shown on the magnetic resonance imaging/Computed Tomography in the acute phase of stroke are more likely to benefit from reperfusion, are suitable candidates for endovascular therapy, and have a better clinical prognosis. The ASTER Trial showed similar results between stent-retrievers and contact aspiration concerning the recanalization grade in anterior circulation occlusions. However, we still observe late and futile recanalizations, secondary either to extended ischemic lesions at baseline, long-time procedures or intraprocedural complications. The First Pass Effect that is the complete/nearly complete recanalization after the first maneuver, independently on the technique used, has been strongly associated with better clinical outcomes . In a recent paper we proposed a novel approach to identify those cases that could be treated with a specific technique (stent-retriever) with higher chances to achieve a complete or nearly complete recanalization, with lower procedure times and lower complication rates. This approach is focused on the identification of a regular or irregular phenotype of the occlusion site in patients with an M1-Middle Cerebral Artery occlusion. The phenotype is defined as "regular" whether the profile of the occlusion is abruptly cut without any irregularity and as "irregular" if any irregularity of the profile of the occlusion is observed. One of the hypotheses that could explain these results could be related to the composition of the clot : a soft and less organized clot could be more easily flattened by the pulsatile flow and therefore determine a regular aspect of the occlusion. A more solid and organized clot would, on the contrary, maintain an irregular profile because it would not be flattened by the blood flow and the contrast medium could highlight the irregularities of the proximal face of the clot. The latter could be a favorable target for the use of a stent-retriever since the interaction between a solid clot and the struts of the stent could increase the chance to retrieve the clot. Therefore, we propose this randomized controlled trial to assess the superiority of stent-retrievers compared to contact aspiration in the treatment of irregular phenotype occlusions of the M1-Middle Cerebral Artery.
As a major breakthrough of acute stroke treatment over the past decade, endovascular thrombectomy (EVT) drastically improved neurological recovery and survival in patients with large vessel occlusion (LVO) ischemic strokes in major clinical trials. Nevertheless, much remained uncertain about the implementation of scientific evidence of EVT into real-world benefits. For instance, healthcare policies that influence critical time-matrices, endovascular thrombectomy techniques that may enhance success rate or prevent complications, or advanced imaging techniques that allow precise prognosis or expansion of treatment populations, should be evaluated. On the other hand, capturing LVO patients who were not able to undergo EVT may reveal the gap between clinical trials and real-world practice in the Asia-Pacific. In this multicenter prospective collaboration across the Asian-Pacific, the investigators aim to evaluate the determinants of effective EVT in the real-world setting.
Several studies have shown an association between platelet function and stroke in patients undergoing carotid thromboendarterectomy (TEA). The present study will assess the correlation between platelet function evaluated by the impedance aggregometry and neurological events in patients undergoing carotid TEA.
