Active clinical trials for "Stroke"

Stroke is associated with disability and impaired quality of life. Persistent motor impairment is common with incomplete recovery of motor function after rehabilitation, mainly in the upper limbs (UL). Robot-mediated therapy (RMT) has been proposed as a viable approach for the rehabilitation of the UL, but more rigorous studies are needed to tailor rehabilitation and to better address the treatment. Brain-derived neurotrophic factor (BDNF) and the serotonin transporter gene (SLC6A4) have been shown to play an important role in post-stroke recovery. After ischemic stroke, disruption and subsequent reorganization of functional brain connections occur both locally and far from the lesion, with the latter possibly contributing to function recovery. This project aims to assess whether epigenetic and genetic variations of BDNF and SLC6A4 can occur in stroke patients after robotic rehabilitation treatment. This study will allow to identify potential genetic and epigenetic biomarkers in post-stroke rehabilitation that could be used to predict the response to a specific rehabilitation treatment and to choose the optimal treatment for the patient (Rehabilomics).

The aim of this study is to validate a smart insoles system in comparison to the gold-standard GaitRite for a pathologic gait. The device evaluate gait parameters in real time thanks to an embedded algorithm based on the processing of inertial measurement unit and 19 sensors signals. At D0 and D7, the patient is evaluated by both the GaitRite® system and the FeetMe Monitor® system simultaneously. Hemiparetic patients have two measurements 7 days apart. The patient repeats 5 trials at a comfortable speed on the GaitRite® mat while wearing the FeetMe® insoles. Each measurement is repeated by 4 different operators. A total of 20 trials are made by the patient.

Objective: Evaluate the feasibility of a multidisciplinary telerehabilitation for chronic stroke patients. Design: Chronic stroke patients eligible for multidisciplinary rehabilitation funded by the Social Insurance Institution were enrolled between September 2017 and March 2018 in a consecutive basis to receive a mixed program of inpatient rehabilitation and telerehabilitation in their homes or a traditional inpatient rehabilitation only. Intervention: A rehabilitation course with a 3-day inpatient stay followed by an 8-week telerehabilitation period completed by 2-day evaluation stay in a rehab center. The control group received conventional multidisciplinary rehabilitation for two weeks in an inpatient setting. Outcome and measures: Change in the Finnish version of Functional Status Questionnaire (FSQFin), the World Health Organization Quality of Life - Short version (WHOQOL-Bref), the Barthel Index, the Beck Depression Inventory (BDI21), and the Goal Attainment Scale (GAS) and a patient satisfaction questionnaire.

Cardioembolism is a postulated mechanism of an embolic stroke of undetermined source (ESUS). The investigators will measure endothelial glycocalyx, aortic elastic properties, oxidative stress, and their association with left ventricular (LV) and left atrial (LA) function in ESUS and age- and sex-adjusted healthy individuals.

The investigators compared the activity and fatigue of upper extremity muscles, pain levels, subject satisfaction levels, perceived exertion, and number of repetitions in Task-Specific Training (TST) compared with Robot-Assisted Training (RAT) in individuals post-stroke.

The purpose of this study is to assess safety and effectiveness of direct oral anticoagulants (DOACs) for stroke prevention in patients with non-valvular atrial fibrillation (AF). The comparison of DOACs between themselves is of interest. The investigators will carry out separate population-based, matched cohort studies, using health administrative databases in nine jurisdictions in Canada, the UK and the US. New users of DOACs for stroke prevention in non-valvular AF will be eligible to enter the cohorts. Follow-up will continue until a hospitalization or emergency department visit for a stroke. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the safety and effectiveness of the different anticoagulation regimens in stroke prevention in AF. The investigators hypothesize that different DOACs will have similar safety and effectiveness profiles.

The purpose of this study is to assess safety and effectiveness of direct oral anticoagulants (DOACs) and warfarin for stroke prevention in patients with non-valvular atrial fibrillation (AF). The comparison of DOACs versus oral vitamin K antagonists, in particular warfarin, is of interest. The investigators will carry out separate population-based, matched cohort studies, using health administrative databases in seven Canadian provinces. New users of oral anticoagulants (DOACs or warfarin) for stroke prevention in non-valvular AF will be eligible to enter the cohorts. Follow-up will continue until a hospitalization or emergency department visit for a stroke. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the safety and effectiveness of the different anticoagulation regimens in stroke prevention in AF. The investigators hypothesize that DOACs and warfarin will have similar safety and effectiveness profiles.

The study aims to increase acute stroke treatment rates in Flint, Michigan through a two-pronged approach of hospital and community level interventions. It also aims to inform future stroke preparedness interventions by exploring the relative importance of hospital optimization and community interventions.

To investigate the acute physiological responses during 20-minute overground gait training with a wearable exoskeleton in persons after stroke

The goal of this study is to understand what brain mechanisms become disrupted when stroke survivors experience delirium. Delirium is an acute reduction in attention and cognition, associated with poor recovery, longer hospitalization and even death. One major factor increasing the risk of delirium after stroke may be spatial neglect occurring after stroke on the right side of the brain. Spatial neglect affects awareness, orientation, and movement. The study will test the hypothesis that the right-dominant brain networks for arousal and attention are affected in both of these disorders. It is expected that the activity and structural integrity of these brain networks will correlate with behavioral signs and severity of delirium and spatial neglect. To test this hypothesis, the study will measure spatial neglect and delirium symptoms in 45 acute (NYC Health + Hospitals/Bellevue ) and 30 subacute (Kessler Institute for Rehabilitation) stroke survivors and evaluate brain scans for these participants. This study may contribute to knowledge about brain bio-markers of delirium, which will greatly aid in delirium detection in stroke and other disorders.
