Summary

Background: * Stroke, also known as acute cerebrovascular attack, is the leading cause of long-term disability worldwide. Stroke survivors are often left with permanent physical and mental disabilities. * Many stroke patients receive different therapies in an attempt to improve their independence and quality of life. However, current strategies are focused on the acute stage after stroke and are of limited influence in improving stroke outcome. One of the main problems of patients who have suffered a stroke is the difficulty in using the hand on the opposite side of the affected hemisphere of the brain; to date, researchers have no successful means to improve the hand function in chronic stages of stroke. * Researchers are interested in developing a pool of individuals for further research into hand and motor function after a stroke. Objectives: \- To perform a screening evaluation of patients referred with stroke to determine their eligibility for current and future protocols studying the effects of stroke on the nervous system and motor function. Eligibility: \- Individuals who have experienced a single stroke on only one side of the brain that occurred at least 3 months prior to participation in the screening study. Individuals must have some residual hand motor function. Design: * Participants in this study will be recruited from patient referrals. * Eligible participants will undergo a 4- to 5-hour screening with a medical history, physical and neurological examination, stroke evaluation, and an anatomical magnetic resonance imaging (MRI) of the brain. The screening visit may be done over the course of more than one day, if needed for patient convenience or test availability. * In addition to the initial outpatient visit, subjects may remain enrolled in this study for up to 15 years and may be contacted to see if they qualify for new branch studies. Subjects may be re-examined up to once per year while they remain in this protocol to confirm ongoing eligibility. The re-examination visits will involve a neurologic evaluation and possible repeat MRI. * No clinical care will be provided under this protocol..

Detailed description

Study Description: This study is intended to identify stroke patients for the studies investigating parameters of peripheral and central nervous system stimulation, possible combination of behavioral parameters, and physical therapy to enhance motor recovery Objectives: The purpose of this protocol is to perform a screening evaluation of patients referred with stroke to determine their eligibility for current and future protocols aimed at understanding the mechanisms underlying plastic changes in the human central nervous system after brain lesions like stroke. Endpoints: The outcome measure is the number of subjects who are eligible to subsequently enroll in HCPS studies. Study Population: Up to Twelve hundred adult patients with history of stroke that occurred at least three months prior to participation and meeting the eligibility criteria, below will be enrolled. Description of Sites/Facilities Enrolling Participants: This protocol utilizes the NIH Clinical Center Outpatient Clinic Study Duration: 15 years Participant Duration: One main screening visit that may be remote, in-person or both lasting approximately 4-5 hours with periodic optional return visits as needed.
