Active clinical trials for "Stroke"

The major problem in stroke survivors that is being addressed in this research project is walking asymmetry, i.e., difference between the legs during walking (e.g. steps on the more affected side are longer than the other). A potential solution to this problem is using new technology like virtual reality during walking training to make stroke survivors have a better sense of their asymmetry. A second problem that we aim to address in this study is whether asymmetry is accurately felt by the stroke survivors and how we can address it. Our ongoing work on the effects of virtual reality on learning new walking tasks in stroke survivors indicates that virtual reality maybe particularly important for those with walking asymmetry. In this study, we plan to recruit stroke survivors who have such asymmetries during walking and have them learn a new walking task in virtual reality. We will also test the stroke survivors to determine if there is a relationship between how well they learn the new task with their ability to feel asymmetry accurately.

Stroke represents the fourth leading cause of death in industrialized nations, after heart disease, cancer, and chronic lower respiratory disease. Approximately one-quarter of the patients suffering a stroke die within one year after the initial event and stroke is a leading cause of serious long-term disability. Although mechanical thrombectomy (MT) has become the standard of care for acute ischemic stroke with proximal large vessel occlusion (LVO) in the anterior circulation, the management of patients harboring proximal occlusion but presenting minor-to-mild stroke symptoms, has not yet been determined by these recent randomized clinical trials. However, patients with proximal occlusions may present with a low NIHSS, a proximal intraarterial occlusion being present in up to 28% when considering patients with an NIHSS ≤ 4. The evidence of benefit from endovascular therapy (EVT) in large vessel occlusion stroke is demonstrated, STAIR IX (Stroke Treatment Academic Industry Roundtable) consensus recommendations were developed that outline priorities for future research in EVT.

Despite the improved treatment of acute stroke over the past decades, those suffering from stroke still are at an increased risk of functional and cognitive decline in the long term. The most common consequences of stroke are functional impairments, cognitive impairments, depression and fatigue. These are also regarded as barriers to achieve optimal adherence to the guidelines regarding secondary prevention. The primary aim of this project is to evaluate the effectiveness of a multimodal individualized intervention to prevent functional decline in the long term after stroke.

Stroke is classically characterized as a neurological deficit attributed to an acute focal injury of the central nervous system (CNS) by a vascular cause, including transient ischemic attack, cerebral infarction, intracerebral hemorrhage, and subarachnoid hemorrhage. It is a major cause of disability and death worldwide. The main purpose of this study to determine the effect of exergaming training compared to visual feedback training on improvement in upper limb function.

The goal of this clinical trial is to study the effects of aerobic exercise during the early rehabilitation after ischemic stroke. The main questions it aims to answer are: How is the recovery of motor function affected by regularly walking during the first 90 days after an ischemic stroke? Does regularly walking during the first 90 days after ischemic stroke affect cognition, physical comfort and the immune system? Participants will exert a heart rate controlled walking programme of walking 3-5 times 30-45 minutes per week. Researchers will compare the recovery of the walking group to a control group without any demands regarding physical exercise.

The purpose of this research study is to understand the efficacy of using an immersive Virtual Reality (VR) environment, with task-specific training, to encourage arm movement following stroke.

The specific study aims will be: 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. 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.

The investigators hypothesize that the presence of a Mayo Clinic certified therapy dog will provide additional benefits above typical treatment for patients currently enrolled in the Mayo Clinic Stroke Rehabilitation Unit.

The purposes of this study include: To test if multiple upper extremity muscles represented within a discrete primary motor cortex site reflect existing muscle synergies after stroke. To test if altered muscle synergies and intermuscular coordination are malleable to motor evoked potential conditioning that induces corticospinal plasticity for the targeted muscle, wrist extensor carpi radialis

The Synchron motor neuroprosthesis (MNP) is intended to be used in subjects with severe motor impairment, unresponsive to medical or rehabilitative therapy and a persistent functioning motor cortex. The purpose of this research is to evaluate safety and feasibility. The MNP is a type of implantable brain computer interface which bypasses dysfunctional motor neurons. The device is designed to restore the transmission of neural signal from the cerebral cortex utilized for neuromuscular control of digital devices, resulting in a successful execution of non-mechanical digital commands.
