NCT ID NCT07389850

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 Results may not be published yet.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.

Summary

This study follows 34 athletes aged 15 to 40 who are having ACL reconstruction surgery. Researchers will test their balance before surgery and again 3 and 9 months after, using a force platform and vibrations to see how the body re-learns to use sensory information. The goal is to understand how proprioceptive reweighting (the brain's ability to adjust balance signals) improves over time, which could lead to better rehab programs.

What this could mean

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

What this could lead to
If successful, this could help design better rehabilitation programs to improve return-to-sport rates after ACL surgery.
What could go wrong
This is a small observational study (34 people) that only measures balance, not treatment outcomes. Results may not apply to all athletes.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

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 34 people

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

Expected to start

Feb 2026

An estimate. Start dates often move.

Expected to finish

May 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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Aged between 15 and 40; * Patients with ACL rupture scheduled for ACL reconstruction surgery; * Patients able to maintain a stable bipedal standing position without technical assistance and with their eyes closed; * Consent of the patient, parents, legal guardians, or guardians to the recording (for minor patients) of data for research and publication purposes. Exclusion Criteria: * Recent osteoarticular pathology (i.e., less than three months) of the lower limbs, whether traumatic or not, other than ACL rupture; * Proven disabling neurological pathology; * Pain in the musculoskeletal system during exercise (excluding the operated knee); * Fatigue assessed using the Borg scale \> 6; * Skin allergy to an adhesive product.
