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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looks at whether a noninvasive device that stimulates the vagus nerve can improve the ability to understand speech in noisy environments for people who have had a traumatic brain injury. Researchers will compare brain responses and speech test scores with and without the stimulation. The study involves 55 adults aged 25-55, including both those with and without a history of brain injury.

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 55 people

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

Started

Mar 2026

Expected to finish

Aug 2027

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

25 to 55 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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: * 25-55 years old * Proficiency in English * TBI group: history of traumatic brain injury by blast or physical trauma * Normal hearing group: no history of traumatic brain injury Exclusion Criteria: * Other neurological diseases or related conditions will be excluded (e.g., large vessel stroke, seizures). We will exclude patients with severe medical diseases that may be associated with impaired cognition (e.g., heart failure, dialysis dependent kidney disease, brain cancer). Further, psychiatric diseases that are unlikely to be related to trauma will be excluded (e.g., schizophrenia). Patients with histories of severe psychiatric disease prior to trauma exposure will be excluded. * Current illicit or prescription drug abuse (within the last two months) * Any taVNS contraindication, including but not limited to the presence of unremovable metal in the left ear, known heart conditions, medications that influence neurotransmitters thought to be critical for vagus nerve stimulation (norepinephrine, acetylcholine, and serotonin), or implanted medical devices such as a pacemaker.
