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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a portable brain stimulation device, used at home along with sensory training, can reduce phantom limb pain in amputees. About 290 participants will either receive the active treatment or continue their usual care. The goal is to see if this approach works in real-world settings and to use machine learning to identify who benefits most.

What this could mean

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

Active substance
transcranial direct current stimulation (tDCS) device and somatosensory training
What this could lead to
If it works, this could offer a convenient, at-home way to reduce phantom limb pain for many amputees.
What could go wrong
This is an early-stage pragmatic trial, so results may not show clear benefit. The treatment requires daily sessions, and some people may not respond.

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 290 people

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

Started

Expected to finish

Jul 2027

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.
