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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.

Summary

This early study tests whether tiny electrode arrays implanted in the arm nerves of three amputees can record nerve signals and provide sensory feedback. The goal is to let users control a prosthetic hand more naturally and feel touch or movement. The device is still experimental and only being tested for feasibility.

What this could mean

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

Active substance
percutaneous Utah Slanted Electrode Arrays (pUSEAs) – tiny wire bundles implanted in arm nerves
What this could lead to
If it works, this could help amputees control a prosthetic hand more naturally and even feel sensations like touch or movement.
What could go wrong
This is a very early study with only 3 people. The device requires surgery, and it is not yet known if it will work reliably or be safe long-term.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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

About 3 people

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

Started

Dec 2020

Expected to finish

Dec 2028

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

18 to 65 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.

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

Inclusion Criteria: * at least 18 years of age and less than 65 years of age * unilateral and bilateral traumatic or elective upper extremity amputations at the transradial level Exclusion Criteria: * incarceration * pregnancy * inability to consent * psychiatric comorbidity * medical conditions that significantly increase the risk of adverse effects of general anesthesia
