BCI Technology for Stroke Rehabilitation
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether using brain signals to guide muscle stimulation can help stroke patients regain better arm use. Researchers aim to determine if this approach can improve movement and alter brain function. Participants will be divided into two groups: one using brain-guided muscle stimulation with Brain-Computer Interface (BCI) technology and the other using a standard approach. Ideal candidates for the trial experienced an ischemic stroke within the last year, are right-hand dominant, and have arm weakness from the stroke. As an unphased trial, this study offers the opportunity to contribute to groundbreaking research that could enhance stroke recovery methods.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this BCI technology is safe for stroke rehabilitation?
A previous study showed that functional electrical stimulation (FES) yielded promising results for stroke recovery. Patients using FES experienced better arm movement and improved quality of life. A review of 25 studies confirmed these positive outcomes.
Research has shown that brain-computer interface (BCI) technology is safe and can enhance arm movement in stroke patients. BCI training allows for repeated and safe rehabilitation, encouraging patient participation.
Overall, both FES and BCI treatments appear well-tolerated and beneficial for stroke recovery. Various studies have tested these treatments, demonstrating positive results for safety and effectiveness.12345Why are researchers excited about this trial?
Unlike traditional stroke rehabilitation methods that often rely on physical and occupational therapy, the new approach using Brain-Computer Interface (BCI) technology is a game-changer. Researchers are excited because this method employs EEG-guided muscle stimulation, allowing for more precise and targeted therapy. This innovative technique could potentially enhance neural recovery by directly engaging the brain's signals to stimulate muscle movement, offering a more personalized and effective rehabilitation process. The use of functional electric stimulation (FES) tailored by EEG feedback is what sets this apart from conventional passive stimulation techniques, providing hope for faster and more significant recovery outcomes.
What evidence suggests that this BCI technology is effective for stroke rehabilitation?
Research has shown that Brain-Computer Interface (BCI) technology holds promise for stroke recovery. Studies have found that BCI-based therapy can enhance arm and hand movement in stroke patients. In this trial, participants will be randomized into different treatment arms. One arm will involve Active Functional Electric Stimulation (FES), which includes EEG-guided muscle stimulation. Another arm will involve Passive FES, which is non-EEG guided.
Functional Electric Stimulation (FES) also aids in stroke recovery. A review of several studies found that FES can improve movement control when used within two months after a stroke. This suggests that FES may be particularly helpful for recovering movement in the arms and hands.15678Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for stroke patients with mild to severe weakness in one arm, who can consent for themselves, and were right-handed before the stroke. They should have had their first stroke within the last year and not be receiving other arm therapies or have pre-existing conditions affecting their arms.Inclusion Criteria

Treatment groups
Experimental Treatment
Active Control
Subjects randomized to this experimental group will be asked to complete the active FES intervention which include EEG guided muscle stimulation. Participation will include behavioral assessments, functional magnetic resonance imaging, functional electric stimulation (FES) treatment, and EEG.
Subjects randomized to this control group will be asked to participate in a passive FES intervention or non-EEG guided muscle stimulation. Participation will include behavioral assessments, functional magnetic resonance imaging, and functional electric stimulation (FES) treatment.
