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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether adding a gentle electrical current to the brain (tDCS) during intensive arm therapy helps women recover arm movement after a stroke. Twenty-four women will receive either real or fake stimulation over two weeks. The goal is to see if the combo improves arm function, quality of life, and the bond with their therapist.

What this could mean

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

Active substance
cerebellar transcranial direct current stimulation (tDCS)
What this could lead to
If it works, this could point toward a safe, low-cost way to boost arm recovery and daily function in women who have had a stroke.
What could go wrong
This is a very small early trial with only 24 participants, so results may not apply to everyone. The added benefit of brain stimulation over therapy alone is uncertain.

Study facts

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 24 people

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

Started

Mar 2026

Expected to finish

Dec 2026

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.

Ages

30 to 85 years

Sex

Female participants only

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: * Women aged between 30 and 80 years. * Who present hemorrhagic or ischemic stroke confirmed by CT with evolution greater than 1 month, corroborated by discharge epicrisis supporting the diagnosis of the patient. * Who presents trunk control in sitting. * Score greater than 14 points on the Minimental Examination scale. * Function of the upper extremity, referring to taking and releasing a small ball with the affected hand and signing or accepting the consent written informed. Exclusion Criteria: * Shoulder pain greater than 4 according to the VAS scale and spasticity greater than 2 according to the Modified Ashworth Scale. * Sensory compromise (visual-auditory). * Presence of severe aphasia. * Cochlear implants, aneurysm clips, brain electrodes and cardiac pacemaker. * Epilepsy or psychiatric disorders (diagnosed in the last 3 months). * Pregnancy, use of psychotropic medications.
