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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 combining spinal cord stimulation with brain-computer interface training can improve arm function in people who had a stroke more than six months ago. Participants will either receive both treatments or the brain-computer training alone. The goal is to see if the combination leads to better movement and daily use of the affected arm.

What this could mean

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

Active substance
spinal cord stimulation device and motor imagery brain-computer interface training
What this could lead to
If successful, this combination approach could offer a new way to restore arm movement in people who have had a stroke, even years later.
What could go wrong
This is an early-stage, single-center study with only 66 participants, so results may not apply broadly. The spinal cord stimulation requires surgery, which carries risks like infection or device problems.

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 66 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

May 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.

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

Inclusion Criteria: * Age 18 to 75 years. * First-ever unilateral supratentorial stroke, either ischemic or hemorrhagic, confirmed by computed tomography or magnetic resonance imaging, resulting in hemiparesis, with disease duration longer than 6 months. * At least one active movement in the wrist or fingers of the affected upper limb, with muscle strength of grade 1 or higher. * Fugl-Meyer Assessment for Upper Extremity score between 10 and 40, indicating moderate upper limb motor impairment. * Change in Fugl-Meyer Assessment score less than 10% within the previous month, indicating a functional plateau. * Clear consciousness and basically normal cognitive function, with Mini-Mental State Examination score of 24 or higher. * Stable clinical condition and ability to understand and cooperate with simple instructions and rehabilitation training. * Written informed consent voluntarily signed by the participant or legal guardian. Exclusion Criteria: * Other neurological diseases that may cause motor dysfunction, such as Parkinson's disease, multiple sclerosis, or spinal cord injury. * Severe visual or auditory impairment that prevents cooperation with visual or auditory feedback instructions of the brain-computer interface system. * Contraindications to spinal cord stimulation surgery, such as severe coagulation dysfunction, infection at the puncture site, severe spinal deformity, or spinal canal stenosis. * History of epilepsy, intracranial metal implants, cardiac pacemaker, or other contraindications to magnetic resonance imaging. * Previous neuromodulation surgery for hemiparesis, such as spinal cord stimulation or deep brain stimulation. * Pregnancy or lactation. * Any other condition judged by the investigator to make the participant unsuitable for this study.
