Mild brain stimulation shows promise for stroke recovery
NCT ID NCT06191549
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a mild, non-invasive brain stimulation called tDCS can improve walking and motor skills in stroke survivors. 70 participants will receive either real stimulation, a sham, or no stimulation, combined with stepping and treadmill training over four weeks. Researchers will measure changes in stepping speed, gait, and brain activity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- anodal transcranial direct current stimulation (a-tDCS)
- What this could lead to
- If it works, this could point toward a safe, non-invasive way to help stroke survivors regain walking ability and motor control.
- What could go wrong
- This is an early-stage study with only 70 participants. The effects may be small or not last long, and not everyone may benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age between 21 and 90 years * Medical history of a unilateral stroke occurring ≥ 6 months prior to enrollment * MRI or CT evidence from the imaging report shown that the stroke involves the corticospinal tract * Hemiparesis involving the lower extremity (Fugl-Meyer Lower Extremity Motor Test) * No passive range of motion limitation in bilateral hips and knees * Limitation of ankle passive range of motion to 10 degrees of dorsiflexion or less * Visual acuity can be corrected by glasses or contact lens to 20/20 * Able to walk independently with/without assistant devices for 10 meters * Able to maintain standing position without any assistance \>= 30 sec (Short Physical Performance Battery) * Evaluation of cognitive status: Mini-mental status examination (MMSE) score ≥ 24 Exclusion Criteria: * Pregnant women * MRI or CT evidence of involvement of the basal ganglia or cerebellum, evidence of multiple lesions, or evidence of any other brain damage or tumors * Have any metal implants, cardiac pacemakers, or history of seizures * Ongoing orthopedic or other neuromuscular disorders that will restrict exercise training * Any vestibular dysfunction or unstable angina * Significant cognitive deficits (inability to follow a 2-step command) or severe receptive or global aphasia
