Filter by:The objective of the present trial is to demonstrate Magnetic stimulation as an useful complementary treatment in order to improve patients' evolution without the need of extensive surgical lesion.
Transient ischemic attack (TIA) or minor ischemic stroke has a high risk of early recurrent stroke. As the golden standard, aspirin effect modestly on acute ischemic stroke, and slightly increase the risk of intracerebral hemorrhage. Recently, edoxaban, a new oral anticoagulant, is proved to be as effective as traditional anticoagulants, while carrying significantly less risk of intracranial hemorrhage. This trial is a randomized, double-blind, multicenter, controlled clinical trial in China. The investigators will assess the hypothesis that a 30-days edoxaban regimen is superior to aspirin alone for the treatment of high-risk patients with acute nondisabling cerebrovascular event.
In patients presenting with acute stroke or transient ischaemic attacks (TIA), von Willebrand factor related parameters, including VWF antigen, activity, FVIII:c and propeptides, ADAMTS13 levels and VWF multimers in cases where ADAMTS 13 was reduced will be measured. Global haemostasis will be assessed using thrombin generation and the relation between increase thrombin generation and VWF explored. Thrombin generation will be performed pre and post filtration for the presence of procoagulant microparticles. These parameters will be investigated acutely, at presentation and in convalescence; in addition, the effect on these parameters of treatment such as thrombolysis may be informative. Correlation between measured parameters and adverse clinical outcome would be used to identify markers of severity and progression of ischaemic stroke and identification of potential novel approaches to therapy that might improve outcome.
The purpose of this study is to determine whether active stimulation of the affected hemisphere will be more effective than simulated current in treatment of stroke
Vocal stimulation may encourage spontaneous breathing in patients dependent on mechanical ventilation. The study will include 30 patients on mechanical ventilation that will be intervened by the vocal stimulation and 30 patients on mechanical ventilation will serve as the control group.
Stroke is one of the leading causes of disability, with an estimated prevalence of 50,000 cases per year in Canada. Less than half of stroke patients regain use of their arm and hand. There is currently no intervention regime that is the gold standard, despite the variety of therapeutic techniques used to treat the upper extremity post-stroke. The use of external feedback to improve motor learning is a technique that has been less studied but shows promise. Therefore, the purpose of this proof of principle study it to test whether different auditory feedback frequencies can facilitate reaching ability in people with stroke. In addition brain scans will be collected that will enable us to determine how stroke severity may impact on one's ability to improve with this technique. We hypothesize that patients who receive less feedback (50% alternate) will have enhanced learning relative to the patients who receive more feedback (100%).
Purpose: To investigate the different sound spectrum of carotid arteries and to analyze its relationship to the vessel disease, and to build a new biomarker about vascular disorder. Methods: To record the carotid phonoangiography with digital stereoscopy and analysis the spectrum with different algorithm such as FFT, wavelet, entropy, complexity, and HHT. The results will be correlated and comparison to the finding in clinical, carotid Doppler and duplex, CTA, MR, and catheter angiography. Statistics: The significance of difference between parameters was computed using t-tests or paired t-test etc. A p value <0.05 is defined as significant.
The amount of active therapy provided to patients on an inpatient stroke rehabilitation unit has been reported as often insufficient. Observational studies have found that in the first 14 days post stroke, patients receive very little therapy and have very low activity levels. More opportunity to practice may, however, improve short-term outcomes such as the level of mobility, endurance, use of the affected arm and leg, and length of stay. The Stroke Inpatient Rehabilitation Reinforcement of ACTivity (SIRRACT) trial will utilize sensors that reveal the type, quantity, and aspects of quality of patient activities outside of the confines of research laboratories. SIRRACT will deploy inexpensive Personal Activity Monitors (PAMs), comprised of triaxial accelerometers worn on the thighs. The objectives of the study are: i. To assess the impact of feedback from Personal Activity Monitors (PAM)s on amount of active practice, walking speed and distance in stroke patients undergoing rehabilitation. ii. To assess the impact of feedback from PAMs on physical, psycho-emotional, cognitive and ecosocial Health-Related Quality of Life of stroke patients undergoing rehabilitation. iii. To assess the acceptability of thigh-strapped accelerometer use among stroke patients undergoing rehabilitation. iv. To assess the reliability and validity of thigh-strapped accelerometer use among stroke patients undergoing rehabilitation. Hypotheses In moderate to severely disabled subjects who are receiving in-patient rehabilitation, daily feedback from PAMs about purposeful activity will increase the amount of active practice by >30%, a higher proportion of subjects who reach the level of independence for walking, and increase walking speed by 25%, leading to higher mean walking speeds and distances at the time of discharge from inpatient rehabilitation. Daily feedback from PAMs on increase in walking speed and distances will improve physical, psychological, cognitive and ecosocial domains of Health-related quality of life.
The purpose of the study is to evaluate the effect of Melatonin (in a dosage of 14mg daily) for a better clinical outcome in the period three days post stroke.
Stroke represents the third commonest cause of death after heart disease and all types of cancer combined, and is the leading cause of long-term permanent disability among adults. Recombinant tissue plasminogen activator (tPA) is currently the only safe medical treatment for acute ischemic stroke but only a small fraction of patients are eligible for a thrombolysis treatment. Current guidelines on thrombolysis post stroke with tPA exclude its uses beyond 3 hours after stroke onset and when time of onset is unknown thus excluding many patients from potentially beneficial treatment. For an appropriate triage and management of patients, it is essential to improve imaging techniques beyond a simple CT scan. Perfusion computed tomography (PCT), currently considered as an investigational technique, permits a quantitative determination of the cerebral perfusion within the brain. It helps distinguish salvageable ischemic penumbra from irreversibly infarcted core in acute stroke patients. This technique has therefore the potential to select patients who are most likely to benefit from thrombolysis with tPA, can be used to predict the benefit after thrombolysis and determine the suitability for other therapeutic interventions. In patients with a primary diagnosis of TIA, PCT would help to identify possible persistent cerebral ischemia but also provide important information for rapid instigation of prophylactic strategies. The diagnosis and management of patients with ischemic stroke and TIA is challenging and is primarily based on clinical assessment in conjunction with neuroimaging. Development of specific molecular biomarkers as additional tools to support a clinical diagnosis, exclude common stroke mimics such as migraine or epileptic seizures, identify patients at risk of disease, and help guide patient treatment by predicting complications following t-PA treatment would be of great value.
