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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 aims to find the best way to place sensors on a prosthetic socket to improve how well people with below-elbow amputations can control their powered arm. Researchers will compare different numbers of sensors (4, 8, or up to 16) and whether targeting specific muscles helps. Participants will test each setup while performing tasks like packing a suitcase, and their control will be rated by trained observers.

What this could mean

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

Active substance
Experimental prosthetic socket with varying numbers of untargeted or targeted EMG channels
What this could lead to
If successful, this could lead to better-fitting, more responsive prosthetic arms that are easier to control in daily life.
What could go wrong
This is a small, early-stage study (32 participants) focused on testing device settings, not a treatment. Results may not apply to all users or lead to immediate product changes.

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 32 people

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

Expected to start

Oct 2025

An estimate. Start dates often move.

Expected to finish

Jun 2026

An estimate. End dates often move.

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 years and older

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: * Unilateral transradial level limb absence * Current or past user of myo-electric controlled prostheses * Six months or more post-amputation * Have adequate limb length such that a wrist rotation device can fit in the check socket * Well-fitting socket as determined by a Socket-Comfort Score of 6 or above * Capable of wearing and operating a prosthesis with a wrist rotator and multi-articulating hand * Capable of understanding and following multi-step instructions and completing the tasks as described * English speaking Exclusion Criteria: * Significant new injury that would prevent use of a prosthesis: The ability to consistently wear a prosthesis and perform activities of daily living and specific performance tasks is necessary to evaluate the relative benefits of the interventions. * Cognitive impairment sufficient to adversely affect understanding of or compliance with study requirements, ability to communicate experiences, or ability to give informed consent: The ability to understand and comply with requirements of the study is essential for the study to generate useable, reliable data. The ability to obtain relevant user feedback through questionnaires and informal discussion adds significant value to this study.
