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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether a brain-computer interface (BCI) system, combined with electrical stimulation and virtual reality, can improve arm movement in chronic stroke survivors. Thirty participants were split into three groups, each receiving different combinations of BCI, electrical stimulation, and virtual reality feedback. The goal was to see which approach best helps the brain relearn how to move 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
brain-computer interface with functional electrical stimulation and virtual reality
What this could lead to
If successful, this could point toward a new rehabilitation method that helps stroke survivors regain arm function without drugs or surgery.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply to everyone. The training is intensive and may not work for all types of stroke impairment.

Study facts

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

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.

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. Have a diagnosis of ischemic or hemorrhagic stroke to unilateral hemisphere, confirmed by neuroimaging examinations, i.e., brain CT or MRI; 2. Chronic phase of stroke, i.e., time after stroke onset more than 6 months; 3. ≥ 18 years old; 4. With severe to moderate levels of hemiparetic upper limb impairment due to stroke, i.e., from levels 1 to 5 in the Functional Test for the Hemiplegic Upper Extremity (FTHUE) 5. Able to give informed written consent to participate in the study. Exclusion Criteria: 1. Previous diagnosis of any neurological disease excluding stroke; 2. Presence of any sign of cognitive problems (Abbreviated Mental Test \< 6) 3. Modified Ashworth score \> 2 in wrist extensor muscle in the hemiparetic upper extremity after stroke (Bohannon and Smith, 1987) or with severe pain that hinders upper extremity movement 4. With other notable impairments of the upper extremity not caused by stroke (e.g., fracture, Rheumatoid Arthritis, or congenital deformity, etc.)
