Filter by:This innovative study will address scientific and clinical areas relatively unexplored in chronic stroke that could lead to greater recovery of walking. Ischemic Conditioning (IC) is a non-invasive, simple procedure that improves motor function, exercise performance and cardiovascular function in healthy controls, but it has never been applied to the stroke population. We postulate that IC enhances the recruitment of motoneurons and results in positive neural adaptations, improves vascular endothelial function and peripheral blood flow, and together these improvements result in an increased capacity to exercise and faster walking speed. Future studies will examine the effects of IC and traditional therapy at different time points of recovery post stroke, durability of IC, molecular mechanisms of neural and cardiovascular adaptation and the efficacy compared with other adjuncts.
Reperfusion is the main goal of early medical interventions after stroke, such as thrombolysis and thrombectomy. Recanalization works only if applied early - the earlier the better, but with a statistical cutoff of 4.5 hours where risk of hemorrhage outweighs the benefit. Recently, this cutoff has been put into perspective using standardized perfusion measurements by magnetic resonance imaging (MRI) or computed tomography (CT). Two trials have shown that revascularization is beneficial up to 24 hours after stroke onset if patient selection is based on perfusion imaging. This suggests interindividual differences in the temporal evolution of an infarction. One explanation for interindividual differences is the variability of the collateral blood supply to the brain, which in turn can maintain different perfusion pressures around the infarct core, also called the penumbra region. Insufficient recruitment of these collateral pathways is an independent negative predictor of poor outcome; the insufficiency may in part be explained by insufficient dilatation of arterioles ("low dilator reserve"). So far, interventions to improve collateral perfusion, e.g., induced hypertension, have not demonstrated effectiveness, likely because our understanding of collateral perfusion, demand-dependent dilatation of arteries (cerebrovascular reserve, CVR) and their effect on microcirculation is insufficient. Functional recovery after a brain lesion is based on plasticity. Plasticity involves the creation of new synapses, fibers (axons and dendrites) and lasting modification to synaptic strength as well as the formation and migration of new neurons. In the cortex surrounding an infarct, plasticity is facilitated by ischemia via modification of gene expression, i.e. a certain time window after stroke, and is stimulated by activity and training. Tissue microcirculatory status and perfusion surrounding the stroke lesion may play a role in the formation of this plasticity. The investigators will analyze the contributions of pre-existing vascular networks, the impact of stroke-affected vessels, timing and degree of recanalization success, brain excitability, and short-term intra-cortical inhibition to better understand how these factors relate to functional recovery after stroke.
Many years of clinical practice experience has found that Ruyi treasure pill can be used to treat nerve meridian injury caused by cerebrovascular disease, but in the end, the clinical efficacy is still lacking systematic clinical evidence-based medical research data. Based on this, the clinical observation of Ruyi treasure pill in the treatment of post-stroke motor and sensory dysfunction was carried out to verify its clinical location, to provide evidence for the application of clinical subdivision of later products and two development of products, and to publish academic papers on the expected research results.
Upper limb (UL) impairment is a common deficit following stroke with only an estimated 20 per cent of patients recovering function.
The primary objective of the study is to demonstrate that SPG (Sphenopalatine Ganglion) stimulation started within 6 hours from stroke onset slows the expansion of the infarct core volume in acute ischemic stroke.
This study will conduct a preliminary evaluation of and obtain user data on a novel game-based visual interface for stroke gait training. Study participants will complete one session comprising exposure to gait biofeedback systems in an order determined by randomization. Participants will be exposed to 2 types of biofeedback interfaces: - newly developed game-based interface (projector screen display) - traditional, non-game interface
The investigators aimed To analyze effect of modified constraint induced movement therapy on upper extremity functions and quality of life of subacute and chronic phase stroke patients with right/left hemisphere damage. A total of 40 patients (20 patients with right hemiplegia and 20 patients with left hemiplegia) were enrolled in our prospective, randomized and controlled trial. Patients were randomized in to three groups. The first group consists of 10 right hemiplegia patients and the second group consists of 10 left hemiplegia patients. First and second group of patients had 10 sessions of constraint induced movement therapy as groups of 4, 5 days a week. Each patient had modified constraint induced movement therapy 1 hour a day with professional support and performed home program by themselves 3 hours a day. Patients' less affected hands were limited by the help of a glove %50 of the time they were awake. Patients were examined before treatment, just after treatment and 3 months after treatment using Box-Block Test, cubes lined, card turned and object gripped in 30 seconds, time it takes to grip and carry a water filled glass to their mouth and putting it back, Motor Activity Log (MAL), Stroke Impact Scale, Fugl-Meyer Motor Assessment Scale.
This clinical trial is a clinical trial for the evaluation of the safety and efficacy of umbilical cord blood (UCB) therapy, UCB and erythropoietin (EPO) combination therapy in adult stroke patients.
Cognitive impairments have severe impact on functional recovery and quality of life after stroke. Current evidence indicated that combining exercise and cognitive training may provide additional benefits on cognition in stroke. This study aims to investigate the effects and mechanisms of two combined methods of computer-based cognitive training with physical exercise in stroke patients with cognitive impairments.
This study aims to compare the effectiveness and safety regarding treatment with standard anticoagulant only or adding antiplatelet to anticoagulant in patients with non-valvular atrial fibrillation and significant atherosclerosis including extracranial, intracranial, coronary or peripheral artery.
