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
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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 tested whether a single session of magnetic brain stimulation (called rTMS) over a specific brain area could improve pointing movements in people who had a stroke. Only one person took part, and the study was stopped early. The goal was to see if the stimulation could make arm movements faster or smoother, but the tiny size means no firm conclusions can be drawn.

What this could mean

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

Active substance
repeated transcranial magnetic stimulation (rTMS) - continuous theta-burst stimulation
What this could lead to
If it works, this could point toward a way to improve arm movement after stroke using non-invasive brain stimulation.
What could go wrong
This was a very small, early study (only 1 participant) that was terminated early, so results are not reliable. The effect of a single session may be temporary or not meaningful.

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

1 person

The number who actually took part.

Started

Mar 2020

Finished

Aug 2021

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.

Ages

18 to 80 years

Sex

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: * Age between 18 and 80y * Right-handed * Right hemispheric stroke confirmed by a 3D imaging technique * at the chronic phase (\>6months) * subject being able to perform a pointing movement of at least 20cm in the anterior space without compensatory movements of the trunk * informed consent * Social security affiliation Exclusion Criteria: * Severe comprehension troubles (language, cognitive or psychiatric disorders) * History of neurological disorders in addition to the stroke * Locomotor troubles affecting the paretic arm * Contraindication to rTMS : epilepsy, intracranial metallic foreign body, cochlear implant, unstable fracture of the skull bones, deafness * pregnancy or breastfeeding * adult subject to guardianship
