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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 3D-printed prosthetic sockets work as well as standard ones for people with below-knee amputations. Eight participants will use their usual prosthesis for three weeks, then switch to a 3D-printed one for three weeks. Researchers will measure mobility, balance, and comfort to see if the 3D-printed version is a good alternative.

What this could mean

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

Active substance
3D-printed prosthetic socket
What this could lead to
If successful, this could show that 3D-printed prostheses are a viable, low-cost alternative to traditional ones, improving access for amputees.
What could go wrong
This is a very small, early-stage trial with only 8 participants, so results may not apply to everyone. The 3D-printed sockets may not be as durable or comfortable as standard prostheses.

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

8 people

The number who actually took part.

Started

Jul 2023

Expected to finish

Mar 2026

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

19 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: * are adults 19+ years, * have a unilateral or bilateral transtibial amputation, * have an existing definitive prosthesis, * use their definitive prosthesis two or more consecutive hours per day, * have no wounds on the residual limb. Exclusion Criteria: * are unable to adequately complete self-report measures or communicate well enough to participate in the end of project interview, * have bilateral upper extremity amputations, * have poorly controlled comorbidities (e.g., unstable diabetes, advanced heart problems)
