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 This study
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 Results may not be published yet.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.

Summary

This early-stage trial is testing whether focused sound wave pulses applied to the head—called transcranial pulse stimulation—can help people recover from a recent ischemic stroke. The study includes adults aged 20 to 80 who had a stroke 1 to 6 months ago and still have motor or language difficulties. Participants receive six sessions over two weeks at different energy levels to find the safest dose and see if it improves movement, balance, and quality of life.

What this could mean

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

Active substance
transcranial pulse stimulation (TPS) using the NEUROLITH® system
What this could lead to
If it works, this could point toward a new non-invasive way to help people regain motor function and balance after a stroke.
What could go wrong
This is an early, small trial focused on safety and dosing, so benefits are uncertain. There are risks such as seizures, bleeding, or worsening neurological symptoms.
