NCT ID: NCT03622879 Recruiting - Stroke Clinical Trials

Mirror Therapy With Cutaneous Electrical Sensory Stimulation on Lower Limb Motor Functions in Stroke

Start date: July 2, 2018
Phase: N/A
Study type: Interventional

This study aims to evaluate the effectiveness of concurrent mirror therapy (MT) and transcutaneous electrical nerve stimulation (TENS) in augmenting the efficacy of the lower limb task-oriented training in people with stroke. It is hypothesize that MT combined with TENS would be superior to sham-mirror therapy with TENS, or MT with placebo-TENS, or control training only in improving lower limb motor functions and walking ability in people with stroke when combined with the lower limb task-oriented training.

NCT ID: NCT03618251 Recruiting - Clinical trials for Stroke, Software Verification, Diffusion Weighted MRI, Neuroimaging

Automated Volume Assessment of Acute Stroke

AVAAS
Start date: March 15, 2018
Phase:
Study type: Observational

Stroke is a common disease. It is increasingly managed in non-specialized centers. The volume of the lesion, evaluated on the diffusion weighted imaging, is a prognostic factor of clinical progression and is useful for the treatment decision. There is therefore a real interest in having a reliable software able to detect the stroke and evaluate the volume of the cerebral infarction. The aim is to provide rapid information to the interventional neuroradiologist and optimize the care of the patient. The Alberta Stroke Program Early Computed Tomography Score currently used to predict response to treatment divides the territory of the middle cerebral artery. It has a few limitations, it is unreproducible and concerns only the territory of the middle cerebral artery. Manual volumetry is a long and also not very reproducible technique. The aim of our study is to evaluate the reproducibility and diagnostic performances of the automated segmentation software based on the diffusion weighted imaging sequence, and to compare it to manual and semi-automatic measurements.

NCT ID: NCT03615079 Recruiting - Depression Clinical Trials

Internet-based CBT After Stroke Pilot

iSAD
Start date: June 11, 2018
Phase: N/A
Study type: Interventional

Mood disorders occur in 25-30% of stroke patients and are associated with lower quality of life, higher mortality, increased healthcare utilization, and higher costs. Cognitive behavioral therapy (CBT) interventions have been shown to both treat and prevent post-stroke mood disorders, thus having the ability to improve quality of life and reduce costs. This study aims to test the feasibility of internet-based CBT combined with a telephone/email based coaching service after stroke.

NCT ID: NCT03611855 Recruiting - Hemiparesis Clinical Trials

Chronic Stroke Rehabilitation With Contralesional Brain-Computer Interface

Start date: April 26, 2018
Phase: N/A
Study type: Interventional

The purpose of this research study is to show that a computer can analyze brain waves and that those brain waves can be used to control an external device. This study will also show whether passive movement of the affected hand as a result of brain-based control can cause rehabilitation from the effects of a stroke. Additionally, this study will show how rehabilitation with a brain-controlled device may affect the function and organization of the brain. Stroke is the most common neurological disorder in the US with 795,000 strokes per year (Lloyd-Jones et al. 2009). Of survivors, 15-30% are permanently disabled and 20% require institutional care (Mackay et al. 2004; Lloyd-Jones et al. 2009). In survivors over age 65, 50% had hemiparesis, 30% were unable to walk without assistance, and 26% received institutional care six months post stroke (Lloyd-Jones et al. 2009). These deficits are significant, as recovery is completed after three months (Duncan et al. 1992; Jorgensen et al. 1995). This large patient population with decreased quality of life fuels the need to develop novel methods for improving functional rehabilitation. We propose that signals from the unaffected hemisphere can be used to develop a novel Brain-Computer interface (BCI) system that can facilitate functional improvement or recovery. This can be accomplished by using signals recorded from the brain as a control signal for a robotic hand orthotic to improve motor function, or by strengthening functional pathways through neural plasticity. Neural activity from the unaffected hemisphere to the affected hemiparetic limb would provide a BCI control in stroke survivors lesions that prevent perilesional mechanisms of motor recovery. The development of BCI systems for functional recovery in the affected limb in stroke survivors will be significant because they will provide a path for improving quality of life for chronic stroke survivors who would otherwise have permanent loss of function. Initially, the study will serve to determine the feasibility of using EEG signals from the non-lesioned hemisphere to control a robotic hand orthotic. The study will then determine if a brain-computer interface system can be used to impact rehabilitation, and how it may impact brain function. The system consists of a research approved EEG headset, the robotic hand orthotic, and a commercial tablet. The orthotic will be made, configured, and maintained by Neurolutions. Each participant will complete as many training sessions as the participant requires, during which a visual cue will be shown to the participant to vividly imagine moving their impaired upper extremity to control the opening and closing of the orthotic. Participants may also be asked to complete brain scans using magnetic resonance imaging (MRI).

NCT ID: NCT03608904 Recruiting - Ischemic Stroke Clinical Trials

Stroke Recovery and Music or No Music

Start date: July 21, 2017
Phase: N/A
Study type: Interventional

The primary outcome of this study is to determine the quantitative increase in connectivity, as measured by fMRI brain and calculated as a percent increase from baseline in patients with ischemic stroke. Eligible patients will receive a listening session of music or spoken word listening, 30 days to 5 years following ischemic stroke. Assessments will include modified Rankin Scale, National Institute of Health Stroke Scale, functional Magnetic Resonance Imaging, motor function tests, and neuropsychological evaluations. Assessments occur at baseline, day 45, and day 90 after starting listening sessions.

NCT ID: NCT03605693 Recruiting - Stroke Clinical Trials

Early Psychological Intervention to Prevent Cardiovascular Event-Induced PTSD (REACH Sub-study)

Start date: August 1, 2018
Phase: N/A
Study type: Interventional

The overall purpose of this project is to determine the feasibility of conducting a randomized clinical trial that compares written exposure therapy with usual care among patients at risk for cardiovascular event-induced PTSD. Patients hospitalized with acute cardiovascular events, including strokes, heart attacks, and cardiac arrest are at risk of developing post-traumatic stress disorder (PTSD) due to the trauma of the acute medical event. The goal of this study is to test the feasibility of conducting a randomized trial involving a psychological intervention to prevent the development of PTSD symptoms in patients at risk for PTSD. Patients who are admitted with these acute cardiovascular events will first be screened for PTSD risk factors while in-hospital after the index event. These risk factors will include elevated threat perceptions at the time of presentation to the hospital or early symptoms of PTSD due to the cardiovascular event. Patients at elevated risk for PTSD will then be randomized to the intervention group or usual care. Those assigned to the intervention will participate in 5 sessions of written exposure therapy in which they are asked to write about the experience of their cardiovascular event with guidance from a trained study clinician. At 1 month after discharge, all patients will be contacted by phone to complete a questionnaire that assesses PTSD symptoms related to the cardiovascular event. Descriptive statistics will be used to understand the feasibility of testing the written exposure therapy intervention as part of a larger, fully powered clinical trial.

NCT ID: NCT03604367 Recruiting - Stroke Clinical Trials

Gait Mate: Examining Neural Networks Engaged During Lower Extremity Movement in the MRI

Start date: February 1, 2018
Phase: Early Phase 1
Study type: Interventional

Less than 50% of stroke survivors progress to independent community ambulation. Even among the stroke survivors who achieve independent ambulation, significant residual deficits persist in balance and gait speed, with 60% of persons post-stroke reporting limitations in mobility related to walking.Consequently maximizing recovery of locomotor function is the focus of neurorehabilitation efforts worldwide. A recently completed clinical trial from members of this investigative team demonstrated that 6 weeks of treadmill training elicits substantial improvements in over ground walking speed and symmetry in persons following stroke. Consistent with the goals of the South Carolina Stroke Rehabilitation Research Center (SCSRRC) and NIH Brain Initiative, the investigators now plan to investigate the effects treadmill-assisted gait training have on cortical control of bipedal movement in chronic stroke patients. Although previous investigators have assessed neural activity during simulated walking using motor imagery, motor imagery does not simulate the typical sensory feedback associated with active movement. To move the field forward, it is necessary to measure active bipedal movement in the MR-environment in healthy volunteers, before moving forward in stroke patients.
