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 Results may not be published yet.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

Summary

This study tests whether a surgically implanted device that sends mild electrical pulses to the spinal cord can improve arm and hand movement in people who have paralysis on one side after a stroke. Twenty participants aged 20 to 70 will receive the implant along with physical therapy. Researchers will measure changes in motor function, sensation, and quality of life over time.

What this could mean

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

Active substance
Epidural electrical stimulation (EES) device
What this could lead to
If it works, this could point toward a new way to help stroke survivors regain arm and hand function and reduce pain.
What could go wrong
This is a very small early study with only 20 people, so results may not apply to everyone. The treatment requires surgery to implant a device, which carries risks like infection or device problems.
