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 Results may not be published yet.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

Summary

This study tests whether combining a special audio-visual training with mild brain stimulation can help people who lost part of their vision after a stroke. Forty-eight participants in the early recovery phase will either get real or fake brain stimulation during daily 90-minute training sessions for 10 days. Researchers will measure changes in their visual field and reaction times over the next year.

What this could mean

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

Active substance
transcranial direct current stimulation (tDCS) and audio-visual training
What this could lead to
If it works, this could point toward a new rehabilitation method to help people regain some vision after a stroke.
What could go wrong
This is a small, early-phase trial with only 48 participants, so results may not apply to everyone. The training is intensive and may not lead to lasting improvement.

Participants

About 48 people

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

Expected to start
