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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two approaches for runners with flat feet (pes planus): custom foot orthoses versus an eight-week foot-core strengthening program. Researchers will measure how each intervention affects hip, knee, and ankle motion during a prolonged run. The goal is to understand which method better supports foot mechanics and may help prevent running injuries.

What this could mean

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

Active substance
custom foot orthoses and intrinsic foot muscle strengthening exercises
What this could lead to
If this trial succeeds, it could help guide runners and clinicians on whether orthotics or exercises better improve running mechanics in flat feet.
What could go wrong
This is a small, early-stage study with only 24 participants, so results may not apply to all runners. It measures movement patterns, not injury rates, so direct benefits remain uncertain.

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 24 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Aug 2028

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.
