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 Results may not be published yet.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.

Summary

This study tests two types of ankle foot orthoses (AFOs) — advanced braces that store and release energy versus conventional ones — in veterans and warriors with lower limb injuries. Researchers will measure mobility, balance, and confidence in daily activities to see if the newer design offers real advantages. Participants will try both types of braces during the study.

What this could mean

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

Active substance
advanced ankle foot orthosis (AFO) and conventional ankle foot orthosis (AFO)
What this could lead to
If advanced AFOs prove better, they could become the new standard for helping people with lower limb injuries walk more easily and confidently.
What could go wrong
This is a relatively small study (75 people), and individual results may vary. The benefits of advanced AFOs might not be dramatic for everyone.

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

Expected to start
