Filter by:The specific study aims will be: 1. To examine the treatment effects of a new digital mirror therapy (MT) system versus a mirror box in patients with stroke by conducting a 4-group randomized controlled trial. 2. To examine the electrophysiological mechanisms of uni-mirror visual feedback (uni-MVF) condition with unimanual training mode, uni-MVF condition with bimanual training mode, and bi-MVF condition with bimanual training mode in the new MT system by EEG.
This is a doble blind, placebo controlled clinical trial to assess safety and efficacy of intravenous administration of Umbilical cord-derived Mesenchymal Stem cells in patients with ischemic stroke within 6 months of onset.
Transthoracic echocardiography (TTE) is recommended in patients with ischemic stroke when cardiac etiology is suspected to help plan secondary stroke management. However, discrepancy for specific clinical recommendation exists between cardiologists and neurologists, and data evaluating usefulness of TTE in unselected patients with cryptogenic strokes (CS) and embolic strokes of undetermined source (ESUS) are lacking. The investigators sought to evaluate the value of routinely performed echocardiography in consecutive CS/ESUS patients. The investigators will perform TTE as recommended by guidelines including agitated saline contrast and speckle-tracking to investigate potential implications for secondary stroke management. In addition, the researchers aim to evaluate the effectiveness of long-term continuous electrocardiogram (cECG) monitorering with newer Holter monitors to detect cardiac arrhythmia in patients with CS/ESUS. In this prospective study, the investigators aim to evaluate 500 consecutive patients, regardless of age, in sinus rhythm with acute IS and potential cardioembolic stroke (CES) or cryptogenic stroke (CS/ESUS) according to Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria. Strokes are determined by magnetic resonance imaging. The researchers will perform TTE as recommended by guidelines including agitated saline contrast and speckle-tracking to investigate potential implications for secondary stroke management. The investigators aim to explore underlying heart conditions and comorbidities among CES and ESUS patients. Data will include left atrium morphology, atrial septal aneurysm, valvular disease, mural thrombus and patent foramen ovale (PFO). Focus will be analysis of data on older patients, as some studies indicate that in ESUS patients >60 years of age, there is a higher prevalence of PFO in patients with low atherosclerosis and cardioembolic risk. This project can potentially guide cardiologists and neurologists, on common grounds, for stroke management of potential cardioembolic origin. Implications of referring all-comers with stroke of potential cardioembolic origin to echocardiography will be illustrated.
The purpose of this study is to identify neural muscle synergies of patients post-stroke and track them during an inpatient acute rehabilitation. To this end, the researchers will use an innovative approach based on the identification of large populations of motor units from recordings of surface high-density electromyography (HD-EMG).
The aim of the PREHENS-STROKE study is to propose a functional replacement device to restore grip capacities in patients with hemiparesis after stroke, unable to actively open the hand to seize objects. The main objective is to evaluate the impact of the use of a self-controlled prehension neuroprosthesis on the ability to perform a standardized grasping task, consisting of grasping, relocating and releasing a glass (palmar grasp) or a spoon (key-pinch), compared to a condition without the use of the prehension neuroprosthesis.
To improve the quality of medical care in the group of poststroke patients, we are planning to examine neurological patients in a rehabilitation clinic simultaneously with a non-contact method (Sleepiz One) and a standard diagnostic polygraphy measurement. This easy and comfortable pre-screening (Sleepiz One) should reduce the barrier for ward physicians to request a sleep study. The method could help to overcome the bottleneck of resource-intense procedures. It is simple to carry out and does not disturb the sleep of the patients. The scoring is done according to the AASM Manual Version 2.6. Patients with a confirmed diagnosis will be informed about therapy options by a sleep physician and receive a recommendation for further therapy in the discharge letter from the rehabilitation clinic. The goal of the study is then to evaluate if a non-contact method, the Sleepiz One, presents an opportunity for a fast and easy pre-screening during rehabilitation. Therefore, the precision of binary classification of subjects based on their sleep apnea severity (AHI >= 15) made by Sleepiz One will be compared to PG data manually scored by expert sleep scorers.
This prospective interventional single center randomized sham controlled dose-escalation study will assess safety, tolerability, feasibility and potential efficacy of transcranial direct current stimulation (tDCS) in acute stroke patients with substantial salvageable penumbra due to a large vessel occlusion who are ineligible for endovascular therapy (EVT). Patients will be randomized in a 3:1 design, to cathodal versus sham (control) tDCS, at each six designed dose tiers. The dose tiers will be increasing in both intensity and duration of the stimulation. The occurrence of symptomatic intracranial hemorrhage will determine the pace of the escalation through the dose tiers.
This Early Feasibility Study (EFS) is a multi-center, open-label single-arm study in 10 acute ischemic stroke (AIS) patients treated with VitalFlow-IS stimulation within 6 hours of symptom onset. The purpose of the EFS is to evaluate initial clinical safety and device functionality in the clinical workflow setting for treatment of acute ischemic stroke patients that will inform design modifications and/or user interface in preparation for next steps consisting of (1) a full safety/feasibility clinical study and (2) randomized controlled pivotal trial with a surrogate endpoint (expedited Premarket Approval (PMA) pathway).
This study is a multi-center, interventional, experimental, prospective, controlled and randomized study. We propose a reeducation protocol based on an early over-solicitation of the ankle dorsiflexor muscles to promote their "awakening", limit the loss of strength associated with the functional loss and thus allow to reach a more effective walking activity. This should encourage social participation following discharge from the hospital. The main objective is to evaluate the impact of this 6 weeks program on walking speed.
This research aims to examine changes in plastic potential of the visual system with time from stroke affecting primary visual cortex. We will measure structural and mechanistic aspects of progressive degeneration along the early visual pathways, correlating them with changes in visual performance, and in responsiveness to visual restoration training. This project will advance both scientific knowledge, as well as technical capability and clinical practices for restoring vision and quality of life for people suffering from cortical blindness.
