Filter by:Patients with chronic stroke (>6 months after stroke) having unilateral upper limb hemiparesis will be recruited. Patients will maintain their usual inpatient rehabilitation including occupational therapy. At baseline (T0) and after 2weeks of enrollment (T1), Fugl-Meyer assessment (FMA) will be assessed at each time. And patients with the changes of FMA between T0 and T1 less than 3 points will be finally recruited. The enrolled patients will receive additional 30-min cathodal transcranial direct current stimulation (tDCS) over the contralesional motor cortex for 10 consecutive weekdays, with maintaining their usual conventional rehabilitation. At T1 and immediately after 10-seessions of tDCS (T2) and 1 month after completing 10-tDCS session (T3), FMA, Actional Research Arm Test (ARAT), Box and Block Test (BBT) and electroencephalography (EEG) were measured.
Undernutrition is a frequent problem in hospitals (at least 30% of patients, SENECA-NHANES studies). Its impact on morbidity and mortality is well known in gerontology, oncology and intensive care. There are very few neurovascular studies dealing with the consequences of undernutrition present before the stroke. Indeed, most of the medical literature concerns only undernutrition acquired after a stroke. The investigator propose to analyze medical data from a cohort of patients over 70 years of age thrombolysed and/or thrombectomized in the neurovascular department between the years 2014 and 2019.
After stroke, people often have difficulty using their hands. Combined brain and nerve stimulation can strengthen the neural pathways that control hand function. In this study, we will deliver combined brain and nerve stimulation during specific time windows that increase activation of neural pathways underlying hand function. We will compare the effects of combined brain and nerve stimulation during these optimal time windows to the effects of combined brain and nerve stimulation applied during random time windows on post-stroke hand function.
Left ventricular thrombus is a recognised complication of acute myocardial infarction, associated with stroke, recurrent myocardial infarction and adverse cardiac remodelling. The prevention, treatment and resolution of thrombus is hampered by a lack of understanding of its initiation, propagation and dissolution. Advanced non-invasive imaging holds major promise in improving our understanding of the incidence and the natural history of left ventricular thrombus as well as providing potential biomarkers to assess disease activity and treatment efficacy. In this prospective observational study, the investigators will recruit patients with recent acute anterior myocardial infarction and screen them for evidence of left ventricular thrombus and subclinical stroke using hybrid positron emission tomography and magnetic resonance imaging (PET/MR). Each patient will undergo PET/MR of the heart and head 7±2 days after acute myocardial infarction. If left ventricular thrombus is present on baseline MR, patients will be started on anticoagulation at the discretion of the attending physician, who will determine the agent used (warfarin or direct oral anticoagulant) and the duration of therapy (3-6 months). Patients will then undergo repeat PET/MR at completion of anti-coagulant therapy and then again after another 3 months. Patients with increased 18F- GP1 activity but no overt thrombus on MR will undergo repeat PET/MR of the head and heart at 3 and 6 months to establish the natural history of this observation and its association with thromboembolism in the brain. They will not routinely receive anticoagulation given the exploratory nature of this study.
This project seeks to determine how post-stroke cognitive impairment moderates motor learning during walking in older adults with chronic stroke and identify brain structural markers that mediate this relationship. The chosen experimental design integrates biomechanical analyses, neuropsychological assessments, and brain imaging techniques to determine the impact of post-stroke cognitive impairment severity on two forms of motor learning (explicit and implicit) and examine the role of the dorsolateral prefrontal cortex in the relationship between cognition and explicit motor learning. Ultimately, this work may lead to the development of a more comprehensive, effective treatment approach to improve walking dysfunction in older adults post-stroke.
The study was to evaluate the use of the Tip Stim device to achieve coordinated movement and grip force in stroke patients under conditions of active and passive stabilization of the trunk.
Branch atheromatous disease (BAD) has been reported to contribute to small-vessel occlusion and is associated with a higher possibility of early neurological deterioration (END). Because the pathology of BAD is due to atherosclerosis, the investigators postulate that early intensive medical treatment with dual antiplatelet therapy(DAPT) and high-intensity statin may prevent END and recurrent stroke. The investigators hypothesise that intensive medical therapy can prevent END in BAD using aspirin, clopidogrel and high-intensity statin.
Spasticity is due to an abnormal processing of a normal input from muscle spindles in the spinal cord.
More than 80% of ischemic stroke (IS) patients have some walking disability, which restricts their independence in the activities of daily living. Physical therapy (PT) significantly contributes to gait recovery in patients after IS. However, it remains unclear, what type of gait training is more effective and which factors may have impact on gait recovery. Two hundred fifty IS patients will be enrolled to undergo a 2-week intensive inpatient rehabilitation including randomly assigned robot-assisted treadmill gait training (RTGT) or therapist-assisted treadmill gait training (TTGT). A detailed clinical and laboratory assessment of gait quality, as well as the degree of neurological impairment, quality of life, cognition and depression will be performed in all patients during the study. We hypothesize that these variables may also affect gait recovery in patients after IS. In a randomly selected 60 enrolled patients, a multi-modal magnetic resonance imaging (MRI), including functional MRI, will be performed to assess neural correlates and additional predictors of gait recovery.
Stroke is a leading cause of disability worldwide affecting both male and female especially in older people. Functional independence and locomotion are hampered in stroke, therefore, affecting their quality of life. Objective: To find the comparative effects of activity base therapy vs strength training on gait performance in chronic stroke patients.
