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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a new non-invasive brain stimulation device called kTMP (kilohertz transcranial magnetic perturbation) to see if it can help improve arm and hand movement in people who have had a stroke. The trial involves 7 adults aged 18-80 who had a stroke at least 12 months ago and still have moderate arm weakness. Researchers will compare different stimulation patterns to find the most effective approach for motor recovery.

What this could mean

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

Active substance
kTMP device (kilohertz transcranial magnetic perturbation)
What this could lead to
If successful, this could offer a new, non-invasive way to improve arm and hand movement in people with long-term stroke-related disability.
What could go wrong
This is a very early, small feasibility study with only 7 participants, so results may not apply widely. The device is experimental and its effectiveness is not yet proven.

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 7 people

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

An estimate. End dates often move.

Lead sponsor

A company

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

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

Inclusion Criteria: 1. Adults aged 18-80 years who have a history of a unilateral stroke ≥ 12 m prior to enrollment. 2. Fugl-Meyer Assessment: Upper Extremity (FMA UE) score 20-55. 3. Ability to communicate, understand, and give appropriate consent. Participants can follow two-step commands. 4. Motor evoked potentials in a hand muscle when stimulating ipsilesional cortex with suprathreshold single-pulse TMS (MEP positive). Exclusion Criteria: 1. Participants with moderate or severe cognitive impairment (MoCA \< 18). 2. Participants with sensory deficits FMA-S ≥ 6/12 (with proprioception ≥ 2/4). 3. Language impairment or behavioral disorder that interferes with their ability to adhere to the protocol or to provide informed consent. 4. Individuals who have a serious uncontrolled medical condition, including but not limited to severe cardiovascular and cardiopulmonary disease. 5. Pregnancy or plans to become pregnant during the study period. 6. Botulinum toxin injections of the affected upper extremity within 3 months prior to onset of study assessments/testing through the last visit. 7. Severe spasticity of the affected upper limb (Modified Ashworth ≥ 3). 8. Absolute contraindications related to non-invasive brain stimulation, including: History of seizures in the last 12 months while taking anti-epilepsy medication Presence of any metal implants in the head (excluding the mouth), such as cortical stimulators and DBS, clips, coils, shunts, stents or skull plates, cochlear implants Permanent eye liner or head tattoos Implanted electronics such as pacemakers, defibrillators, intrathecal baclofen pumps or vagus nerve stimulator History of experiencing a serious adverse event during a previous transcranial magnetic stimulation (TMS) session
