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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether a non-invasive device that gently stimulates the vagus nerve through the ear is tolerable for children who have had a stroke. One child will receive ear stimulation paired with occupational therapy sessions over four weeks. The goal is to see if the child can complete all sessions without significant side effects, and to measure any changes in arm function.

What this could mean

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

Active substance
a device that delivers gentle electrical pulses to the ear to stimulate the vagus nerve (transcutaneous auricular vagus nerve stimulation, taVNS)
What this could lead to
If well tolerated, this approach could pave the way for larger studies testing whether ear nerve stimulation helps children regain arm function after a stroke.
What could go wrong
This is a very early, single-participant feasibility trial, so results may not apply to others. The device may cause discomfort or side effects like skin irritation or dizziness.

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 1 person

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

Expected to start

Jul 2026

An estimate. Start dates often move.

Expected to finish

Sep 2026

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.

Ages

13 to 21 years

Sex

Anyone

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: * Childhood stroke survivor - either arterial ischemic stroke or intracerebral hemorrhage. * Stroke must be childhood onset, defined as occurring day 29 of life to 18 years of age (per the American Heart Association's definition of childhood stroke) * 6 months or greater from stroke onset * Arm impairment, defined as pediatric stroke outcome measure of 1 or greater of affected arm. * Affected arm Fugl-Meyer score of 60 or lower. * Able to participate in occupational therapy sessions. Exclusion Criteria: * Craniectomy without replacement of bone flap. Patients who underwent craniectomy will need the bone flap reattached prior to participation. * Presence of cranial metal implants or implant device that could be affected by taVNS: cochlear implant, implanted brain stimulator, or programmable ventriculoperitoneal shunt.
