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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study tests a new non-invasive brain stimulation device called kTMP (kilohertz transcranial magnetic perturbation) to see if it can improve arm and hand movement in people who had a stroke more than six months ago. The study enrolls 7 adults aged 18-80 with stable upper limb weakness. Researchers measure changes in motor function using standard tests and motion capture. The goal is to assess whether this approach is feasible and potentially effective for chronic stroke rehabilitation.

What this could mean

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

Active substance
kTMP (kilohertz transcranial magnetic perturbation) device
What this could lead to
If successful, this could point toward a new non-invasive way to help stroke survivors regain arm and hand function without surgery or drugs.
What could go wrong
This is a very small pilot study with only 7 participants, so results may not apply to everyone. The technique is new and its effectiveness and safety are not yet proven.

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

7 people

The number who actually took part.

Started

Sep 2025

Finished

Apr 2026

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

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.

Show the full entry requirements

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

Inclusion criteria: 1. Age 18-80 years with stable upper limb motor dysfunction caused by a single ischemic and/or hemorrhagic stroke greater than 6 months prior to recruitment 2. Fugl-Meyer Assessment: Upper Extremity (FMA UE) score 20-50 3. Motor evoked potentials in a hand muscle when stimulating ipsilesional cortex with suprathreshold single-pulse TMS (MEP+), a proxy of residual corticospinal function. Exclusion criteria: 1. Participants with cognitive impairment (MoCA \< 20), language impairment that interferes with their ability to adhere to the protocol or to provide informed consent. 2. Individuals who are pregnant, have uncontrolled medical problems including but not limited to severe cardiovascular and cardiopulmonary disease, severe alcohol or drug abuse within the past year, or major depression. 3. Contraindications related to non-invasive brain stimulation
