Stroke Clinical Trials

Speech-language therapy is generally found to be helpful in the rehabilitation of aphasia. However, not all patients with aphasia have access to adequate treatment to maximize their recovery. The goal of this project is to compare the efficacy of telerehabilitation or Aphasia Remote Therapy (ART) to the more traditional In-Clinic Therapy (I-CT). Read Less

The goal of this clinical trial to test whether a remotely delivered behavioral activation-based intervention called "teleABLE" works better than a health education intervention for (1) reducing sitting time and (2) improving health-related quality among adults who were diagnosed with stroke within the past 12 months. Participants in this study will: * Complete questionnaires at Weeks 1, 8, and 24 * Wear an activPAL monitor at Weeks 1, 8, and 24 * Participate in the teleABLE intervention (12 sessions) or the health education intervention (6 sessions) * Complete an interview at Week 24 Read Less

This study evaluates the efficacy of smartphone-based speech therapy administered at home compared with usual care. Participants will be randomized into the treatment and waitlist control groups with an allocation ratio of 1:1. Read Less

Patients with stroke frequently suffer from aphasia, a disorder of expressive and/or receptive language, that can lead to serious health consequences, including social isolation, depression, reduced quality of life, and increased caregiver burden. Aphasia recovery varies greatly between individuals, and likely relies upon the capacity for neuroplasticity, both at a systems level of reorganized brain networks and a molecular level of neuronal repair and plasticity. The proposed work will evaluate genetic and neural network biological markers of neuroplasticity associated with variability in aphasia, with a future goal to improve prognostics and identify therapeutic targets to reduce the long-term burdens of aphasia.

Stroke is a leading cause of disability in the U.S. and many Veteran stroke survivors live with severe disability. Despite recent advances in rehabilitation treatments many stroke survivors have persistent physical and mental difficulties such as reduced physical and cognitive function and depression. Developing innovative treatments that address these problems is necessary to improve long-term outcomes for stroke survivors. Aerobic exercise (AEx) can improve physical and cognitive function, and reduce depression. Additionally, AEx may enhance physical rehabilitation by making the brain more receptive to, and consequently improving the response to an intervention. Therefore, combining AEx with physical rehabilitation has the potential to improve multiple aspects of stroke recovery. This study will examine the effect of combining AEx with physical rehabilitation on physical and mental function in stroke survivors. By gaining a better understanding of the effects of this combined intervention the investigators aim to advance the rehabilitative care of Veteran stroke survivors. Read Less

CAPTIVA-MRI is an observational multimodal MR imaging study that is ancillary to the CAPTIVA trial \[a 3-arm, double-blind Phase III trial conducted at approximately 115 StrokeNet sites randomizing patients with stroke attributed to 70-99% intracranial atherosclerotic stenosis (ICAS) to aspirin plus ticagrelor, clopidogrel, or rivaroxaban.\] The primary goal of this ancillary study is to determine if MRI biomarkers can potentially identify ICAS patients who fail best medical management. The CAPTIVA-MRI study leverages the CAPTIVA trial design and implementation to capture information that will inform and facilitate the next generation of ICAS trials and the management of patients with ICAS.

Primary Goal: To test the hypothesis that among stroke patients 18-75 years with ≥3 SDOH risk factors, SHIFT will improve: (1) functional outcomes as measured by the SIS (Primary Outcome), (2) physiological outcomes as measured by changes in blood pressure and cognition, (secondary outcomes) and (3) epigenetic allostatic load biomarkers (exploratory outcome) such as DNA methylation (DNAm) and telomere length, at 6 months and 1-year post-stroke, compared with usual care (UC).

The proposed research will evaluate the individual and combined effects of task-specificity and intensity of rehabilitation interventions on locomotor function, community mobility and quality of life in patients with subacute (1-6 months) post-stroke. Read Less

The goal of this study is to: 1. Assess the usability of the SynPhNe device in a home environment. 2. Evaluate the efficacy of the SynPhNe home use device to improve motor hand function in chronic stroke subjects as compared to standard care alone. Read Less

Subjects with chronic stroke (\> 6 months post-stroke) will learn a new walking pattern through distorted visual feedback. Retention of the pattern will be tested without visual feedback immediately after learning and 24 hours later. Subjects will be randomly assigned to the control group or the exercise group. The control group will simply complete the learning task. The exercise group will complete 5 minutes of exercise immediately following the first retention test to test for the effects of exercise on retention 24 hours later. Read Less

The goal of this clinical trial is to test a gait (walking) training program in non-ambulatory (unable to walk) chronic stroke survivors. The main question it aims to answer is: • Will gait training improve the cardiovascular system in non-ambulatory chronic stroke survivors better than a sitting leg cycling exercise? Participants will walk on a treadmill with a partial body-weight support system and the gait training device. Researchers will compare with a leg-cycling exercise to see if there are significant differences in resting heart rate, systolic blood pressure (SBP), and A1c levels in the blood. Read Less

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.
