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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a walking program on uneven surfaces can improve walking skill and confidence for people who use a lower-limb prosthesis. Thirty-five adults with leg amputations will practice walking on flat and uneven treadmills for four weeks. Researchers will measure how many sessions they attend and how their walking speed changes.

What this could mean

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

Active substance
locomotor training (walking practice on flat and uneven surfaces)
What this could lead to
If successful, this could lead to a simple, safe walking program that helps people with leg prostheses feel more confident and walk better on different surfaces.
What could go wrong
This is a small, early feasibility study with only 35 participants. It measures adherence and walking speed, not long-term benefits, so results may not apply widely.

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 35 people

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

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: * lower limb amputation at ankle (Symes) level and above * age 18+ years * fitted with a walking prosthesis and use it regularly for home and/or community ambulation * good socket fit, assessed by a score of 8-10 on the socket fit comfort scale * able to walk for three minutes at a time with or without an assistive device Exclusion Criteria: * leg/foot ulcer or other conditions that cause pain during weight-bearing * poor skin integrity that could cause tissue breakdown by walking * cardiovascular, respiratory or other critical health conditions that preclude moderate physical activity * unilateral or bilateral upper limb absence or loss at the wrist and above that precludes use of handrails bilaterally, or would require asymmetrical adaptation to body posture for use. * pregnancy
