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 Results may not be published yet.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 study looked at how people with cervical or myoclonus dystonia perceive their own actions, known as the 'sense of agency.' Researchers used computer tasks and brain scans to measure how accurately participants felt in control of their movements. The goal was to link these feelings to brain structure and symptom severity.

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 research could improve understanding of why some people with dystonia feel a lack of control over their movements, potentially guiding future therapies.
What could go wrong
This is an observational study, not a treatment trial. It aims to gather knowledge, not test a cure or therapy, so direct patient benefits are not expected.

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