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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Carbon fiber custom dynamic orthoses (CDOs) include a full-length footplate, a stiff posterior spring, and a cuff that wraps around the leg below the knee. CDOs restore function after limb trauma, decrease forefoot loading, and reduce pain. However, initial introduction to a CDO is not consistent, so this study is being conducted to determine if different methods of training alter forefoot loading during gait. Unimpaired adult participants will be randomized to one of three groups: 1) no feedback, 2) visual feedback of forefoot force, and 3) visual feedback of cuff forces. All participants will walk at a controlled speed on a treadmill without the CDO, after initial introduction to the CDO, and after completing two rounds of training in the CDO.

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 51 people

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

Expected to start

Nov 2026

An estimate. Start dates often move.

Expected to finish

Jun 2027

An estimate. End dates often move.
