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
Registered, but not yet taking participants.
By invitation only This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 checks whether heart rate and blood pressure readings taken from the finger or arm agree with standard chest measurements during a mild electrical stimulation of the ear. One healthy volunteer will be monitored at rest, during 10 minutes of ear stimulation, and during recovery. The goal is to see if simpler monitoring spots can be trusted for future research. No direct medical benefit is expected, but the findings may help improve how we track nervous system responses.

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 vagus nerve stimulation (taVNS) device
What this could lead to
If successful, this study could help researchers choose simpler, more reliable ways to measure how the nervous system responds to ear stimulation in future studies.
What could go wrong
This is a very small, early-stage study with only one participant, so results may not apply to others. The measurements may not match well across different body sites, limiting the usefulness of the approach.

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.

Started

Mar 2023

Expected to finish

May 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

18 to 40 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: * Age 18 to 40 years. * Healthy volunteers without known chronic disease or acute illness at the time of participation. * Able and willing to comply with study procedures and instructions. * Provided written informed consent. Exclusion Criteria: * Any cardiovascular disease, arrhythmia, hypertension, or similar condition. Any neurological disorder (e.g., diabetes mellitus, peripheral neuropathy, epilepsy). * Any diagnosed psychiatric disorder. * Pregnancy or suspected pregnancy. * Ear conditions that prevent stimulation (infection, open wound, pain/tenderness) or the presence of a piercing at/near the stimulation site. * Vigorous exercise within 24 hours prior to the measurement. * Caffeine intake, smoking, or alcohol consumption within 4-6 hours prior to the measurement. * Marked intolerance or hypersensitivity to the devices or the procedure. * Inability to follow instructions during measurements or refusal to complete the session.
