Personalized Transcranial Direct Current Stimulation in Stroke Recovery
What this study is about
The central objective of this application is to explore the neural substrate of personalized tDCS (ptDCS) and to determine whether the paradigm for each stroke patient can predict the amount of sustained clinical improvement through increased connectivity as measured by a biomarker of plasticity.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Symptomatic ischemic or hemorrhagic stroke verified by computerized axial tomography or magnetic resonance imaging resulting in hemiparesis (MRC 1-4).
- Age more than 18, Male or Female, All racial and ethnic groups
- Entry into the study \>3 months post onset
- Modified Ashworth Scale Score \<3 in the involved upper extremity
- Passive range of motion within functional ranges at the shoulder, elbow, wrist and hand
- Able to follow 2 step commands
Exclusion criteria
- Patients with history of severe alcohol or drug abuse, psychiatric illnesses like severe depression, poor motivational capacity, or severe language disturbances, particularly of receptive nature or with serious cognitive deficits (defined as unable to follow study instructions).
- Patients with bilateral paresis, or weakness or sensory damage due to peripheral causes (e.g. peripheral nerve injury, muscle or orthopedic injury etc.)
- Patients with severe uncontrolled medical problems (e.g. cardiovascular disease, severe rheumatoid arthritis, active joint deformity of arthritic origin, active cancer or renal disease, any kind of end-stage pulmonary or cardiovascular disease, or a deteriorated condition due to age,epilepsy or others).
- Patients with unstable cardiac arrhythmia.
- Patients with metallic implants in the head, patients with pacemakers, patients with craniotomies, including burr holes who cannot be safely stimulated
- Patients with seizures
- Non-English speaking individuals will only be eligible if they can provide the appropriate translator for all the sessions of the study as no funding is available to pay for such services.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
