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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 mild electrical current applied behind the ears can improve how healthy adults sense and control their balance. Each participant will try two types of stimulation (low-frequency and high-frequency) as well as a no-stimulation session. Researchers will measure how accurately they detect motion, track movement, and correct for disturbances.

What this could mean

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

Active substance
noisy galvanic vestibular stimulation (nGVS) delivered through electrodes on the mastoid bones
What this could lead to
If it works, this could point toward a non-invasive way to enhance balance and spatial awareness in healthy people or astronauts.
What could go wrong
This is a small, early-stage trial in only 18 healthy adults. The effects may be subtle or not translate to real-world performance.
