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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This small safety trial tests whether a non-invasive device that stimulates the vagus nerve through the ear can safely improve hand and arm function in 10 adolescents with spastic cerebral palsy. Participants will use the device during upper limb rehabilitation sessions. The main goal is to check for side effects and see if the therapy is feasible.

What this could mean

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

Active substance
non-invasive transauricular vagus nerve stimulation device (Vagustim)
What this could lead to
If it works, this could point toward a safe, drug-free way to improve hand and arm function in adolescents with cerebral palsy.
What could go wrong
This is a very early, small safety trial with only 10 participants, so results may not apply to everyone. The device may not improve motor function at all.
