What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are studying how well people who have had a stroke learn a complex arm and hand skill when they train with one arm versus both arms. Participants include healthy volunteers, people in the early days after a stroke, and people more than six months past a stroke. They practice on two rehabilitation robots, the REAplan and the Dextrain, while brain scans map the areas involved in arm control. The goal is to understand which training approach suits different types of stroke damage.

What this could mean

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

Active substance
Motor skill training with the REAplan rehabilitation robot and the Dextrain dexterity device
What this could lead to
If the approach works, it could help therapists choose whether to train one arm or both arms after a stroke, and guide how rehabilitation is matched to each patient's brain injury.
What could go wrong
This is an observational comparison, not a treatment trial, so it may not show which training method is better. Results from 200 people may not apply to every stroke survivor, and brain imaging findings may not translate into better recovery.

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 200 people

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

Started

May 2026

Expected to finish

Dec 2031

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.
