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 Results may not be published yet.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.

Summary

This study looks at very small movements (micro-movements) in patients who have been unconscious for over a month after a severe brain injury. Researchers will use emotional stimuli to see if these movements, along with brain scans, can detect hidden awareness. The goal is to better classify each patient's level of consciousness and improve predictions of recovery. 179 participants will be followed for 6 months.

What this could mean

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

What this could lead to
If successful, this could lead to better ways to detect awareness in patients who appear unresponsive, improving diagnosis and care.
What could go wrong
This is an observational study, not a treatment trial. It may not directly change patient outcomes, and results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
