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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether a brief 'test-drive' of different prosthetic feet can help veterans with below-knee amputations find the one that gives them the best stability and balance. About 100 veterans will try out several prosthetic feet in a lab and then wear each one at home for a week. The goal is to see if a short trial can predict which foot will work best in daily life, potentially reducing falls and improving confidence.

What this could mean

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

Active substance
prosthetic foot devices
What this could lead to
If successful, this could lead to a simple 'test-drive' method for matching veterans with the best prosthetic foot, reducing falls and improving confidence.
What could go wrong
This is an early-stage study with only 100 participants, so results may not apply to everyone. The test-drive approach may not predict long-term real-world outcomes accurately.

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.

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

Inclusion Criteria: * has a unilateral (one leg) transtibial (below-knee) amputation * has used a prosthetic limb for walking for at least six months * has a comfortably fitting prosthetic socket * has a removable prosthetic foot attachment (i.e., is not rigidly attached to the back of the socket) so it can be used with study prosthetic feet * be able to walk with a prosthetic limb sufficiently to participate in the experiment walking trials Exclusion Criteria: * contralateral limb or upper limb amputation that would interfere with completion of study activities * are unable to use more than one of the test feet for any reason (e.g., excessively long residual limb that is not compatible with wearing study prosthetic feet) * unable to walk under the minimal necessary study walking conditions in order to complete the study procedures without undo stress * current surgical, neurological, rheumatologic, or lower limb musculoskeletal problem that significantly impairs ambulation (e.g., current ulcer, terminal illness) * weight greater than 263lbs. * inadequate cognitive or language function to consent to participate * currently incarcerated * impaired decision-making ability or the use of a legally authorized representative
