Tailored brain zaps show promise for stroke recovery
NCT ID NCT06286800
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a personalized form of brain stimulation (tDCS) can help people who had a stroke more than 3 months ago regain arm movement. Researchers will use brain scans to tailor the stimulation to each person and measure changes in brain connectivity and motor function. The goal is to see if this approach leads to lasting improvements in arm and hand use.

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. * Pregnancy * 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.
