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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether adjustable prosthetic sockets can help veterans with lower leg amputations by measuring pressure and comfort during different activities. Twenty-five veterans will use a custom socket with adjustable panels for two weeks, then perform tasks like walking and sitting while sensors record pressure. The goal is to see if these sockets maintain a good fit over time, potentially reducing the need for costly replacements.

What this could mean

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

Active substance
adjustable prosthetic socket
What this could lead to
If successful, this could lead to better-fitting prosthetic sockets that last longer, reducing the need for frequent replacements and improving comfort for veterans.
What could go wrong
This is a small, early-stage study with only 25 participants, so results may not apply to everyone. The adjustable socket might not work well for all users or activities.

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 25 people

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

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

Aug 2029

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a US federal agency other than the NIH.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

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: * Veterans with lower limb amputation * have a unilateral transtibial amputation * wear a prosthesis for at least 4 hours a day by self-report * at least one-year post-amputation * have a modular prosthesis that includes a four-bolt socket attachment * can walk on a treadmill Exclusion Criteria: * have an improper fit and suspension with their current prosthesis, and a good fit cannot be achieved with clinical resources * have current skin irritation or injury to the residual limb, osteoarthritis, injury, or pain that interferes with walking ability
