Active clinical trials for "Stroke"

The purpose of this study is to determine whether a non-invasive brain stimulation technique, transcranial direct current stimulation (tDCS), combined with traditional cognitive therapy will improve cognitive function in patients with subacute stroke.

This research project will investigate motor imagery training in stroke rehabilitation during which patients receive feedback in real time from their brain activity measured with ElectroEncephaloGraphy (EEG). The investigators hypothesize that the feedback training allows to internally stimulate brain motor networks in order to promote functional recovery of the hand.

The study's methodology will be a single-blind, multicenter, parallel-group randomized controlled trial (RCT). The sample consists of stroke patients (supratentorial ischemic and hemorrhagic stroke of anterior territory) between 18 and 80 years of age, separated into 3 groups of 20 participants. The experimental group called "controlled DoF", the control group 1 called "non controlled DoF" and the control group 2 called "Conventional". The "controlled DoF" group will use an exoskeleton that will restrict the movement of the trunk and upper limb to release only the joint to work in the plane of interest. The "non-controlled DoF" group will receive the same therapy time as the previous group but without any restriction of joint movements. The training will be functional with multiarticular and combined planes tasks. All groups receive the conventional rehabilitation of the health center (ideally 45 minutes 1 per day) and the "Conventional" group receives only this intervention. Using motion sensors, clinical scales, and electroencephalography (EEG), the data will be obtained pre-intervention, post-intervention, and in a follow-up at 3 and 6 months.

A prospective, single blind, parallel group, randomized control trial to determine if early, intensive lower extremity activity delivered by a physical therapist and a parent in partnership improves gross motor function more than usual care.

The purpose of the study is to explore the feasibility of using a wearable device, called a myoelectric-computer interface (MCI), to improve arm movement in people who have had a stroke. Impaired arm movement after stroke is caused not just by weakness, but also by impaired coordination between joints due to abnormal co-activation of muscles. These abnormal co-activation patterns are thought to be due to abnormal movement planning.The MCI aims to reduce abnormal co-activation by providing feedback about individual muscle activations. This randomized, controlled, blinded study will test the home use of an MCI in chronic and acute stroke survivors.

Falls in daily life are one of the most significant complications for people with stroke. Fall rates are particularly high soon after discharge from stroke rehabilitation. A new type of balance training, called reactive balance training (RBT), can reduce fall rates after discharge from stroke rehabilitation. In our previous study, RBT was implemented as part of routine care, and as a result, the dose of training was different for each participant; participants completed between one and twelve 30-minute sessions of RBT. Previous research in healthy older adults suggests that a single session of RBT is enough to lead to lasting changes in reactive balance control and reduce fall rates in daily life. It is not clear if the same is true for people with stroke, who have more severe impairments and might need a higher dose of training to achieve the same benefits. The overall goal of this work is to determine the optimal dose of reactive balance training for people with stroke who are attending rehabilitation. This pilot study will determine the feasibility of a clinical trial to address this larger goal. People with sub-acute stroke will be randomly assigned to one of three groups: 1 session, 3 sessions, or 6 sessions of RBT. Each session will be 45 minutes long, and will occur as part of participants' routine out-patient rehabilitation. We will use our experiences with this pilot study to help design a larger study. Specifically, we will use this pilot study to answer the following questions: 1) what is the optimal sample size; 2) how long will it take to reach this sample size; 3) what outcome measures should be used; 4) how feasible is it to prescribe a specific dose of RBT to people with sub-acute stroke; and 5) what two intervention groups should be included in the larger trial?

Participants in this study will help test and develop a virtual reality (VR) system that is being designed to help people with spatial neglect after stroke.

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.

The development of intravenous thrombolysis has greatly improved the rate of recanalization and reperfusion in patients with acute ischemic stroke, increasing the proportion of patients with good outcome and reduced mortality. The guideline recommends that patients with ischemic stroke should be treated with intravenous thrombolysis within 4.5 hours. The latest meta-analysis found that ischemic stroke with onset time of 4.5-9 hours with infarction core volume <70ml, ischemic penumbra volume >10ml, and hypoperfusion volume / infarction core volume >1.2 could be benefit from intravenous thrombolysis. The DAWN clinical trial has shown that patients with ischemic stroke with large vessel occlusion with onset time of 6-24 hours could be benefit from endovascular treatment after screening by multi-mode imaging. Therefore, we hypothesize that patients with ischemic stroke with onset time of 4.5-24 hours with a definite penumbra may also benefit from intravenous thrombolysis. The purpose of this study is to explore whether the patients with ischemic stroke with onset time of 4.5-24 hours can benefit from intravenous thrombolysis if they meet the standard of CT perfusion screening.
