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

Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

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 tests a new questionnaire called DBS-QoLs designed to measure quality of life in people with generalized dystono-dyskinetic syndromes who are treated with continuous electrical neuromodulation (deep brain stimulation). The goal is to see if this tool can reliably assess both physical abilities and emotional well-being, and how patients feel about their treatment. Participants will fill out the questionnaire at the start, after 15 days, and after one year. If successful, this could give doctors a simpler, more complete way to evaluate the real-world impact of brain stimulation therapy.

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 validated, this questionnaire could give doctors a better way to understand how deep brain stimulation affects patients' daily lives and emotions.
What could go wrong
This is a small, early-stage validation study (33 people) focused on a questionnaire, not a treatment. The scale may not prove reliable or useful in broader practice.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
