What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a gentle electrical current applied to the brain (tDCS) combined with hand exercises can improve hand function in people who had a stroke. Fifty-six participants will receive either real or sham tDCS for 20 sessions over four weeks. Researchers will use MRI scans to see how the brain rewires itself and track hand recovery for six months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
transcranial direct current stimulation (tDCS) device
What this could lead to
If it works, this could point toward a non-drug way to improve hand movement after a stroke.
What could go wrong
This is a small, early-stage study with only 56 people. The sham group may show similar improvement, and results may not apply to all stroke survivors.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 56 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

May 2026

An estimate. Start dates often move.

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

30 to 75 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Diagnosed with stroke according to the "Diagnostic Criteria for Major Cerebrovascular Diseases in China, 2019", confirmed by cranial CT or MRI. 2. First-ever unilateral subcortical stroke (involving the corona radiata, basal ganglia, thalamus, internal capsule, etc.). 3. Age 30-75 years. 4. Right-handed prior to stroke onset. 5. Stroke onset ≥ 2 weeks. 6. Hemiplegic hand function at Brunnstrom Stage I-III. 7. Written informed consent provided by the patient or legally authorized representative. Exclusion Criteria: 1. Any contraindications to MRI. 2. History of other neurological disorders or substance abuse. 3. Unstable conditions or rapidly progressive/malignant diseases, e.g., severe atrial fibrillation. 4. Severe skin allergies. 5. Inability to cooperate with basic communication or assessments, such as severe aphasia.
