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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 non-invasive brain stimulation technique called temporally interfering (TI) electrical stimulation can help people with disorders of consciousness, such as a minimally conscious state or unresponsive wakefulness syndrome. Participants receive either real TI stimulation or a sham version, and researchers measure changes in consciousness using the Coma Recovery Scale-Revised and brain activity markers. The goal is to see if TI can safely promote recovery of awareness in patients who have been unconscious for at least a month.

What this could mean

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

Active substance
temporally interfering electrical stimulation (TI)
What this could lead to
If effective, TI could offer a new way to help some patients regain awareness after severe brain injury.
What could go wrong
This is a small early-stage trial with only 28 participants, so results may not apply broadly. The treatment involves brain stimulation, which carries unknown risks in this population.
