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 Results may not be published yet.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.

Summary

This small proof-of-concept study tested a non-invasive device that uses sound and light to help people with hemianopia (blindness in half of the visual field). Five adults with stable hemianopia underwent training sessions where they were exposed to matching sound and visual cues in their blind area. The goal was to see if this multisensory approach could improve visual detection. Results are very early and limited.

What this could mean

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

Active substance
multisensory rehabilitation device
What this could lead to
If it works, this could point toward a non-invasive way to improve vision in people with hemianopia.
What could go wrong
This was a very small proof-of-concept study with only 5 participants. Results may not apply to everyone, and the approach is still experimental.
