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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at how changing the stiffness of the footplate in a carbon fiber leg brace (called a custom dynamic orthosis) affects foot pressure, walking mechanics, pain, and comfort. Twenty healthy adults will wear the brace with different footplate stiffness levels while researchers measure forces under their feet. The goal is to find the best stiffness to reduce pain and improve function after trauma injury.

What this could mean

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

Active substance
Carbon fiber custom dynamic orthosis (CDO) with adjustable footplate stiffness
What this could lead to
If successful, this could help design better orthoses that improve walking and reduce pain for people with foot or ankle injuries.
What could go wrong
This is a small, early-stage study in healthy adults, not patients. Results may not apply to injured individuals or lead to immediate treatment changes.

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 20 people

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

Started

Dec 2025

Expected to finish

Dec 2027

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

18 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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 * Between the ages of 18 and 65 * Healthy without current complaint of lower extremity pain, spine pain, open wounds or active infections, or medical or neuromusculoskeletal disorders that have limited their participation in work or exercise in the last 6 months * Able to hop without pain * Able to perform a full squat without pain * Ability to read and write in English and provide written informed consent * Ability to fit in a generic sized CDO Exclusion Criteria * Diagnosed with a moderate or severe brain injury * Lower extremity injury resulting in surgery or limiting function for greater than 6 weeks * Injuries that would limit performance in this study * Diagnosed with a physical or psychological condition that would preclude functional testing (e.g. cardiac condition, clotting disorder, pulmonary condition) * Visual or hearing impairments that limit walking ability or limit the ability to comply with instructions given during testing * Require use of an assistive device * Unhealed wounds (cuts/abrasions) that would prevent AFO use * BMI \> 40 * Pregnancy
