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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers at National Taiwan University Hospital are studying how the brain combines visual information with movement in people who have Parkinson's disease. They will compare 21 people with freezing of gait, 21 without it, and 21 healthy adults of similar age. Participants complete hand-tracking tasks, visual perception tests, and brain stimulation measurements to see how visual and motor brain regions communicate.

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 researchers map how vision and movement connect in the brain, this could point toward targeted therapies for freezing of gait and other motor problems in Parkinson's disease.
What could go wrong
This is a small observational study of 63 people, so it can only show associations, not cause and effect. The findings may not apply to all people with Parkinson's disease.
