The purpose of this study is to evaluate the safety, feasibility, and efficacy of an exoskeletal network of passive, multi-joint springs for forearm supination. Also known as the forearm ExoNET, the device is a passive, robotic device that will properly assist forearm supination in the post-stroke adult population.
The purpose of this research study is to measure the effect of participating in extra arm exercise in addition to standard rehabilitation exercises in the Acute Rehabilitation Unit. This study will compare two different ways to perform the extra arm exercise. The first is following a customized program of hand and arm exercises that will be developed for study participants by an experienced rehabilitation therapist. The second is moving a participants arm back and forth when they are sitting in their wheelchair by using a moveable wheelchair arm rest (Boost).
Participants are being asked to participate in a research study conducted by Shih-Chiao Tseng, PT, Ph.D. at Texas Woman's University. This research study is to determine whether low-intensive brain stimulation can enhance learning of a leg movement task. The investigators also want to know if brain stimulation can improve the nerve function and walking performance. Our goal is to understand any relationship between brain stimulation and overall movement control improvement. Participants have been invited to join this research if they have had a stroke before or they are healthy adults aged 21 years or older. Research evidence shows stroke can induce permanent brain damage and therefore may cause a person to have trouble learning a new task. This in turn may significantly impact the recovery of motor function in stroke survivors. In addition, the investigators also want to know how a healthy person learns this new leg task and see if her/his learning pattern differs from a stroke survivor. This study comprises two phases: Phase I study investigates short-term effects of brain stimulation on leg skill learning and only requires two visits to TWU. The total time commitment for Phase I study will be about 6.5 hours, 3.5 hours on the first visit and three hours on the second visit; Phase II study is an expanded version of Phase I study to investigate long-term effects of brain stimulation on leg skill learning and requires to complete 12 visits of exercise training paired with brain stimulation over a four-week period and additional one visit for follow-up test. The total time commitment for Phase II study will be about 20 hours, a total of 18 hours for 12 exercise training sessions and two hours for a follow-up test. The investigators hypothesize that people with chronic stroke will show a slower rate of acquiring this leg skill as compared to healthy adults. The investigators also hypothesize that co-applying brain stimulation with 12 sessions of exercise training will enhance skill learning of this leg task for people with chronic stroke and this 12-session exercise program may exert beneficial influences on the nerve function and leg muscle activation, and consequentially improve motor control for walking.
The Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.
The purpose of this study is to learn more about stroke and obtain information that may serve as the basis for future investigations. It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of time); and 3) evaluate the data to generate ideas for future studies. Patients 18 years of age or older with suspected acute stroke or TIA may be eligible for this study. Subjects will be recruited from patients who present with stroke at the emergency department of Suburban Hospital in Bethesda, Maryland. The study will gather data collected from diagnostic and laboratory tests the patient undergoes as part of standard medical care, including findings of medical and neurological examinations and other tests. In addition, studies will be done for research purposes only to gather data about stroke and TIA. These may include the following: * Blood and urine tests not more than 2 tablespoons of blood will be drawn for various tests. * Electrocardiogram (EKG) (heart tracing)-electrodes placed on the chest wall detect the heartbeat and heart rhythm. * Computed tomography (CT) scan of the head-specialized X-rays are used to obtain images of the brain. * Magnetic resonance imaging (MRI) of the brain-a strong magnetic field and radio waves are used to produce images that provide information about the brain tissue and blood vessels. * Transcranial Doppler (TCD)-sound waves are used to image the arteries of the brain and neck. * Echocardiogram-sound waves are used to image the heart and evaluate heart function. Patients may be asked to return to Suburban Hospital for follow-up testing in 1, 3, and/or 12 months, when some of these tests may be repeated to assess changes over time
Apathy is a common set of symptoms seen in many people following a stroke. Apathy occurs when a person has lost motivation, becomes withdrawn, and stops doing things that used to be important to them. Apathy has a large negative impact on a person's quality of life, and can also have a large impact the people who take care of them. There are currently no FDA-approved treatments to help with apathy, and other services like therapy may be difficult to access for people who have had a stroke. To address this problem, investigators are conducting a study to find out if a form of treatment called repetitive transcranial magnetic stimulation (rTMS) can be safe and helpful for people struggling with apathy after a stroke. This study will apply a new form of rTMS which can be delivered quickly to a part of the brain called the medial prefrontal cortex (mPFC). This study will help establish whether this treatment is safe, comfortable, and effective for people with apathy after a stroke, and will help researchers develop new forms of treatment.
This trial tests a promising new intervention to promote post-stroke neural reorganization and functional recovery. The Q Therapeutic (BQ 3.0) is a wearable medical system that produces and delivers non-invasive, extremely-low-intensity and low-frequency, frequency-tuned electromagnetic fields in order to stimulate neuronal networks with the aim of reducing disability and promoting neurorecovery. This trial is a prospective, single-arm, open-label, single center clinical trial designed to evaluate the safety, feasibility, and efficacy of the Q Therapeutic (BQ 3.0) System in the rehabilitation of people with chronic stroke.
Evaluate the effectiveness of the Q Therapeutic (BQ 3.0) System for individuals with chronic stroke in improving upper extremity function as determined by change in functional outcome measures after 3-month treatment, including in-clinic and at-home sessions.
Background: Stroke is the fifth leading cause of death in the United States. It is also a leading cause of disability. More than 70% of people who survive strokes have mental impairment or dementia. Medical factors, such as the severity of the stroke, affect whether a person will have mental impairment afterward. But social factors, such as education and ethnicity, seem to play a role as well. Researchers want to learn more about how social and lifestyle factors affect a person s chances of maintaining mental functions after a stroke. Objective: To better understand how social and lifestyle factors affect the risk of mental impairment after a stroke. Eligibility: People aged 18 years and older who had a stroke and a brain scan while they were enrolled in NIH Study 01N0007 (Natural History of Stroke Study). Design: Participants will have 1 study visit, by telephone. The call will last about 45 minutes. Participants will talk about their health since their stroke. They will answer questions about themselves. Topics will include: * Their race * Education * Ethnicity * Employment * Marital status * Residence address * Recent health history * Medical insurance They will have tests of their memory, attention, and language skills. They will repeat numbers and words forward and backward. Researchers will look at the data and imaging scans collected during participant s enrollment in NIH Study 01N0007. This data will include: * The hospital that first saw the participant at the time of their stroke. * The type of imaging that was first used then. * The primary diagnosis at admission. * Other medical details.
People living with the cognitive effects of stroke are at risk for recurrent stroke and further cognitive decline. Also problematic is that stroke risk clusters in families and biological family members of people who have ischemic stroke may also be at increased risk of stroke and/or cognitive decline. The primary goal of this study is to test the feasibility of a virtually delivered cognitive strategy training and health coaching program to reduce vascular risk and promote brain health in persons with stroke and their biological family members.
