Filter by:Carotid endarterectomy (CEA) is one of the surgical treatment methods for the reconstruction of arterial stenosis or occlusion. Perioperative stroke, cerebral hemorrhage,hyperperfusion syndrome and death are main complications of CEA. Investigator have established a risk prediction model of the procedure based on vascular characteristics and hemodynamic parameters retrospectively. This prospective study was aimed to verify the predictive ability of CEA comprehensive prediction model through the analysis of patients receiving CEA procedure in the investigator's center in the next two years.
The aim of this study is to have a positive effect on the static and dynamic balance of vibration applied to the foot base in stroke patients.
As with other real=world connected systems, studying the network structure of multiple interactions in the brain (holism versus reductionism) has profound implications in the comprehension of emergent complex phenomena like, for example, the capability to functionally reorganize after cerebrovascular "attacks" or stroke. This dynamic skill, which is known in neuroscience as brain plasticity, is not only interesting from a network perspective, but it also plays a crucial role in determining the motor/cognitive recovery of patients who survive a stroke. Network analysis of functional connectivity (FC) patterns estimated from neuroimaging techniques such as electroencephalography (EEG), magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) has allowed a major breakthrough in the understanding of physiopathology of stroke from a system perspective. Recent evidence from cross=sectional studies1,2 highlights that stroke lesions generally induce i) critical deviation from optimal (i.e. small=world) network topologies supporting both segregated and integrated information processing, ii) altered inter=hemispheric connectivity and modularity, iii) and abnormal region centrality in the ipsilesional hemisphere as well as in the contralesional hemisphere. While these findings provide new descriptors on how stroke lesions affect the functional brain network organization and how this correlates with the resulting behavioral impairment (e.g. hemiplegia, aphasia), they only represent a static picture of the brain plasticity, which is instead intrinsically dynamic, and partially inform on the chances of single patients to recover their motor/cognitive functions. These aspects dramatically limit the investigator's ability to fully understand the brain organizational mechanisms after stroke and to probe the predictive power of possible network=based neuromarkers of recovery. The ATTACK project aims to overcome these technological and methodological barriers by implementing the following three=fold strategy: 1. acquiring a longitudinal dataset of brain and behavioral data in stroke patients and healthy controls, 2. developing new analytic tools to characterize and generate temporally dynamic brain networks, 3. building network=based models of functional recovery after stroke, accounting for individual patients.
TRIDENT Main Study: TRIDENT is a multicentre, international, double-blinded, placebo-controlled, parallel-group, randomised controlled trial of a fixed low-dose combination BP-lowering pill ("Triple Pill") strategy on top of standard of care, in patients with a history of acute intracerebral haemorrhage (ICH) and systolic blood pressure (SBP) levels defined as 'high normal to borderline high', and on either minimal or no BP-lowering treatment according to current guidelines. MRI Sub-Study Centres capable of specific MRI of the brain sequences will be identified. The patients in the TRIDENT main study who are identified to be eligible for the MRI Sub-Study will undergo MRI scans at baseline (6 weeks to 6 months post-randomisation) and at 36-month follow-up time points. All data collected will be analysed centrally at the Brain and Mind Centre (BMC) in Sydney, Australia.
This study in an observational, prospective and longitudinal study. The aim of the study is to evaluate the effect of botulinum toxin type A (BTX) injections into the elbow flexors on the reduction of spastic co-contractions (spastic co-contraction index, SCCI) during an active elbow extension in chronic post-stroke patients.TBA injections are performed as part of routine care
Rehabilitation robotics is increasingly used because it enables the patients to practice a wide array of movements. Dynamic balance training is essential for gait rehabilitation and robotised devices enhance repeatability, objectivity and precision of such training combined with monitoring and recording of kinematic and kinetic data. The aim of the study is to explore the effect of robot-assisted gait training on dynamic balance, symmetry and take-off in patients after stroke. The investigators will conduct a randomised intervention study where one group will receive visual feedback on gait status and the other group will receive kinetically-assisted training using a robotised device in addition to the visual feedback.
The study evaluates the effect of early follow up in a preventive clinic with stepwise treatment of high blood pressure and lowering blood cholesterol. Half the participants were randomized to the preventive clinic group and the other half to control group with the usual treatment: one visit to the outpatient clinic three months after discharge with a diagnosis of stroke or transient ischemic attack (TIA)
This study is being conducted as a feasibility clinical investigation to collect safety and technical performance data of the WOLF Thrombectomy Device for the removal of thrombus in the neurovasculature.
This is a feasibility study to alter the Microsoft Kinect software to be used as a rehabilitation tool. The prototype used is still in the early developing stage. The purpose of this research study is to develop a prototype of altered Microsoft Kinect Software and determine its use in improving the function of the study subjects' weaker extremities. The altered software will allow a viewing of the mirror image of the involved limb as it is moved. However, the image that is viewed will reflect normal movement even if the limb cannot move normally. By viewing normal movement of the weaker limbs the "mirror neuron" network in the brain will become activated and will ultimately improve the function of the weaker side.
Post-Acute Care(PAC) had been inaugurated in Taiwan for almost four years and current essays revealed positive effects upon general improvements in stroke patient after PAC training. During acute phase, a stroke patient would admit to internal medicine or surgical ward and transferred to rehabilitative ward for more intensive therapeutic programs, restoring muscle power and promoting activity of daily life(ADL) ability. Under relative stable condition, the patient would transfer to PAC institution or hospitals afterwards for continuing rehabilitative program if the patient is acknowledged to have rehabilitative potentials. However, there's still lacking of investigation upon whether the length of stay in PAC correlates to general improvements. Thus, stroke patients' functional ability, such as activities of daily living (ADL) function, swallowing ability and so on, as well as their corresponding scales were assessed on the first and last day during PAC hospitalization. Statistical analysis was conducted via SPSS ver21.0 to compare the relationship of improvements in functional ability and the length of stay in PAC. We're looking forward to the final results!
