Stroke Clinical Trials

Stroke survivors have compromised vascular function which may contribute to secondary stroke risk, cardiovascular disease, and may limit their exercise tolerance. No studies have examined how femoral blood flow responds to both passive leg movement, a measure of microvascular function, as well as active leg contractions, a measure of the hyperemic response to exercise. Leg muscles with a reduced blood flow response to movement could be associated with decreased neuromuscular function, such as leg strength and fatigue. Preliminary data showing a single bout of ischemic conditioning may improve vascular function and muscle activation in healthy adults and individuals post-stroke. Therefore, the investigators want to examine if ischemic conditioning will also improve the blood flow response to passive leg movements as well as during single leg active contractions. Read Less

The Hawks in Motion (HIM) High Intensity Exercise program is designed to implement the American Physical Therapy Clinical Practice Guidelines and American College of Sports Medicine recommendations for exercise for people with neurologic disability. Doctor of Physical Therapy (DPT) students administer the HIM High Intensity Exercise Program. A prior study evaluated the feasibility, safety, and efficacy of the HIM High Intensity Exercise Program and found it feasible, safe, and effective for 30 people with neurologic disabilities between the ages of 8-99 years. The investigators would like to evaluate whether participation in the HIM High Intensity Exercise Program affects mobility in everyday life. Physical activity will be measured one week before program implementation and one week after to assess if the participants' mobility in everyday improved. Read Less

This innovative study will address scientific and clinical areas relatively unexplored in chronic stroke that could lead to greater recovery of walking. Ischemic Conditioning (IC) is a non-invasive, simple procedure that improves motor function, exercise performance and cardiovascular function in healthy controls, but it has never been applied to the stroke population. We postulate that IC enhances the recruitment of motoneurons and results in positive neural adaptations, improves vascular endothelial function and peripheral blood flow, and together these improvements result in an increased capacity to exercise and faster walking speed. Future studies will examine the effects of IC and traditional therapy at different time points of recovery post stroke, durability of IC, molecular mechanisms of neural and cardiovascular adaptation and the efficacy compared with other adjuncts.

People living with stroke have very low aerobic fitness, which can negatively impact brain health. Identifying the best exercise which includes exercise stimulus type (interval, continuous) or intensity, how hard to exercise (moderate, high) that benefit aerobic fitness, vascular health, and the brain's main blood vessels after stroke are unknown. This study is designed to determine the preliminary efficacy of high-volume HIIT to moderate intensity exercise using a seated stepper exercise device that allows the arms and legs to move back and forth.

This study will contribute to the field of stroke rehabilitation research by expanding the investigator's understanding of the neural mechanisms responsible for the development and expression of abnormal flexion synergy, a primary movement impairment due to stroke. The study will longitudinally evaluate motor tract morphology and motor impairment/function in an attempt to develop early neuroimaging-based predictors of the development of flexion synergy and its impact on reaching and hand recovery (6 month). The study will utilize quantitative motor testing (kinematics and kinetics) to measure motor impairment and reaching and hand function. Both neuroimaging and quantitative motor testing will be conducted within 96 hours-, 2 weeks-, 3 months-, and 6 months-post stroke. The knowledge gained by this study will provide crucial structural and functional neuroimaging evidence that demonstrates the timeline of progressive ipsi- and contralesional motor pathway (including bulbospinal pathways) changes and the associated development of flexion synergy that grossly impacts reaching and hand function in individuals with moderate to severe stroke.

This study aims to assess the feasibility and acceptability of "MAYA", a mobile cognitive behavioral therapy app for anxiety and mood disorders, in adults who have had a stroke. Read Less

This study examines the effectiveness of the cardiac rehabilitation program for stroke patients. The study will examine if patients with stroke, who receive cardiac rehabilitation in addition to their standard of care treatments, demonstrate improved recovery of function. It will also examine if these patients have reduced hospital readmission, reduced rate of recurrent stroke, and mortality. Read Less

The purpose of this research study is to explore whether genetic testing can offer a personalized and timely approach to assist physicians in making more informed medication decisions for stroke or high-risk transient ischemic attack (TIA) patients during their hospital stay. Read Less

This study has two interventional components, the first is a cross-over design and the second is a randomized control trial. Both will evaluate the effectiveness of transcutaneous (non-invasive) spinal cord stimulation on gait and balance function for individuals with hemiplegia due to stroke. Read Less

Background: When people have a stroke, they often have difficulty moving their arms and hands. Transcranial magnetic stimulation (TMS) can improve how well people with and without stroke can move their arms and hands. But the effects of TMS are minor, and it doesn t work for everyone. Researchers want to study how to time brain stimulation so that the effects are more consistent. Objective: To understand how the brain responds to transcranial magnetic stimulation so that treatments for people with stroke can be improved. Eligibility: Adults ages 18 and older who had a stroke at least 6 months ago Healthy volunteers ages 50 and older Design: Participants will have up to 5 visits. At visit 1, participants will be screened with medical history and physical exam. Participants with stroke will also have TMS and surface electromyography (sEMG). For TMS, a brief electrical current will pass through a wire coil on the scalp. Participants may hear a click and feel a pull. Muscles may twitch. Participants may be asked to do simple movements during TMS. For sEMG, small electrodes will be attached to the skin and muscle activity will be recorded. At visit 2, participants will have magnetic resonance imaging (MRI). They will lie on a table that slides into a metal cylinder in a strong magnetic field. They will get earplugs for the loud noise. At visit 3, participants will have TMS, sEMG, and electroencephalography (EEG). For EEG, small electrodes on the scalp will record brainwaves. Participants will sit still, watch a movie, or do TMS. Participants may be asked to have 2 extra visits to redo procedures. Read Less

The purpose of this study is to investigate the feasibility of a mobile telerehabilitation software for post-acute stroke care for Rio Grande Valley (RGV) stroke survivors with community health worker (CHW) at-home support and to estimate the functional health, mental health (depression), and caregiver burden outcomes of this new CHW-supported, at-home rehabilitation service delivery model and to identify salient barriers to and facilitators of adopting and delivering the new rehabilitation delivery model to further disseminate the model in real-world communities.

Stroke is a leading cause of long-term disability. Research has placed little emphasis on integrating care partners (CP) (family members) into the rehabilitation process without increasing negative care partner outcomes. The research team has developed and implemented a novel, web-based care partner-focused intervention (CARE-CITE) designed to foster problem-solving and skill building while facilitating care partner engagement during stroke survivor (SS) upper extremity practice of daily activities in the home setting. By providing a family-focused approach to rehabilitation interventions, this project will help develop more effective treatments that improve CP and outcomes after stroke. Read Less
