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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study investigates how deep brain stimulation (DBS) influences the brain's ability to adapt walking patterns and reduce freezing of gait in people with Parkinson's disease. Participants walk on a split-belt treadmill (one belt faster than the other) with their DBS turned on and off, while off medication. Researchers measure how quickly and completely step length adjusts, aiming to understand the brain circuits involved. The goal is to improve DBS therapy for better mobility.

What this could mean

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

Active substance
deep brain stimulation (DBS) device
What this could lead to
If successful, this study could reveal how DBS affects walking and freezing episodes, potentially guiding better DBS settings to improve mobility.
What could go wrong
This is an observational, early-stage study with only 60 participants, so results may not apply to all Parkinson's patients. It measures brain activity and walking patterns, not a new treatment.

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

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 60 people

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

Started

Expected to finish

Jul 2027

An estimate. End dates often move.

Lead sponsor

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.

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * consensus diagnosis of idiopathic PD by fellowship trained movement disorders neurologists at the Normal Fixel Institute of Neurological Diseases; * chronically stable DBS, defined as having had DBS for at least 6 months in duration with optimized DBS settings; * Age between 18 - 80 years old per the FDA data sheet for PD DBS; * no dementia according to the clinical diagnostic criteria for PD dementia; * ambulatory without the use of walking aids, or another person's assistance. Exclusion Criteria: * other previous neurological surgery; * suspicion of other neurologic diagnoses such as atypical parkinsonism, or Alzheimer's disease.
