Stroke Clinical Trials

This experimental trial is investigating the use of magnetic stimulation of the brain as a possible treatment for people with post-stroke fatigue. Fatigue is a common condition after a stroke and can negatively impact an individual's ability to perform desired social and physical activities. Magnetic stimulation of the brain has been shown to improve signs and symptoms of related psychological (e.g., depression) conditions. Participants in this trial will receive a type of magnetic stimulation called repetitive magnetic stimulation, or rTMS. The investigators will measure feelings of fatigue, and other clinical characteristics related to mood and cognition, before and after participants receive rTMS. Read Less

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 will assess the effects of transcranial alternating current stimulation (tACS) on language recovery after stroke. 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.

This study will investigate the effects of mild electrical stimulation in conjunction with speech therapy for people with post-stroke aphasia to enhance language recovery. Read Less

The purpose of this study is to investigate the effects of transcranial magnetic stimulation (TMS) on motor cortex excitability in individuals who have suffered stroke and to study the influence of the phase of the oscillatory rhythm (mu frequency) on motor excitability in stroke individuals.

This pilot project aims develop a need-based community stroke self-management program that would improve the stroke self-management self-efficacy and competencies among African American stroke survivors living in rural Alabama. This study is a mixed-methods study to collect data related to the needs of these individuals and develop a need-based intervention based on the actual needs/ preferences of our target population. The specific aims are to assess the needs, access barriers, existing resources for a stroke self-management program; and develop a Community Stroke Self-management Program for improving stroke survivors' abilities to manage their medication adherence, diet, Physical Activity (PA) requirements, symptoms, and psychological distress to better meet their needs, expectations, and preferences. Another aim is to examine the feasibility and acceptability of delivering the CSSP after tailoring the proposed intervention in Aim 2a) among the AA chronic stroke survivors living in rural Alabama.

Sensorimotor impairments following stroke often involve complex pathological changes across multiple joints and multiple degrees of freedom of the arm and hand, thereby rendering them difficult to diagnose and treat. The objective of this study is to evaluate multi-joint neuromechanical impairments in the arm and hand, then conduct impairment-specific treatment, and determine the effects of arm versus hand training and the effects of passive stretching before active movement training.

Sensory and motor impairments following stroke can lead to substantial disability involving the arm and hand. The investigator hypothesized that excessive local and cross-coupled stiffness, diminished individuation and proprioceptive acuity will be present among multiple degree of freedom in the upper limb. The stiffness and spasticity will increase with time post-stroke. The objective of this study is to quantify the progression throughout the arm and hand during recovery from stroke. The investigator will measure the clinical assessment scores, and neuromechanical properties including range of motion, active and passive cross coupling, and spasticity by the IntelliArm robot.

Following a stroke, many individuals have a high risk of falls, which can negatively influence quality of life. Unfortunately, current treatments have not effectively addressed this problem. This study investigates whether two methods of delivering mechanical perturbations during walking have the potential to improve post-stroke walking balance and reduce real-world fall incidence.

The NSR-GENE study is a longitudinal cohort study of approximately 300 parent-child trios from the Neonatal Seizure Registry and participating site outpatient clinics that aims to evaluate whether and how genes alter the risk of post-neonatal epilepsy among children with acute provoked neonatal seizures. The researchers aim to develop prediction rules to stratify neonates into low, medium, and high risk for post-neonatal epilepsy based on clinical, electroencephalogram (EEG), magnetic resonance imaging (MRI), and genetic risk factors.

The purpose of this investigator-initiated study is to establish if powered exoskeleton therapy as a part of a rehabilitation program can be used as a standard of care in stroke rehabilitation. Read Less
