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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a small, non-invasive device that delivers mild electrical pulses to the ear to see if it can help people with chronic jaw pain (TMD). About 40 adults will use the device at home daily for a few weeks. The main goal is to see if people find it easy and comfortable to use, while also tracking changes in pain, mood, and thinking skills.

What this could mean

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

Active substance
Transcutaneous Auricular Neurostimulation (tAN) device
What this could lead to
If this works, it could offer a drug-free, non-invasive option for people with chronic jaw pain who haven't found relief from standard treatments.
What could go wrong
This is a small, early feasibility study with only 40 people. It's designed to test if the device is acceptable, not yet to prove it works. The sham group may also show improvement, and results may not apply to everyone.

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 40 people

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

Started

May 2026

Expected to finish

Sep 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

18 to 65 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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18 to 65 years. * Diagnosis of temporomandibular disorder (TMD) based on the Diagnostic Criteria for Temporomandibular Disorders (DC-TMD). * Pain intensity of at least 4/10 on the Numeric Rating Scale (NRS) over the past two weeks. * Chronic pain duration of at least three months, consistent with diagnosis of chronic TMD. * Willingness to self-administer transcutaneous auricular nerve stimulation (tAN) at home and comply with study procedures. * Fluency in English to ensure comprehension of study materials and assessments. * Access to a smartphone or computer with internet to complete electronic study surveys and check-ins with the research team. Exclusion Criteria: * Neurological conditions that may interfere with study outcomes, including epilepsy, stroke, multiple sclerosis, or traumatic brain injury. * Use of implanted neuromodulation devices, such as vagus nerve stimulators, deep brain stimulators, or cochlear implants. * Unstable or severe psychiatric disorders, including active psychosis or severe depression with suicidal ideation. * Pregnancy or intention to become pregnant during the study period. * Skin conditions or other contraindications that prevent safe electrode placement on the auricular region (e.g., metal in the cymba concha that is unable or not willing to remove). * History of trauma (e.g., skull fracture) or periauricular surgery (e.g., temporomandibular joint replacement, acoustic neuroma removal) which would affect the location and function of the target peripheral innervation. * Use of both surgical and non-surgical bone conduction hearing devices.
