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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 Stanford study tests whether people with knee osteoarthritis can learn to change how they activate their calf muscles while walking, using a vibrating feedback device. The goal is to reduce the force on the knee joint. Thirty-one participants will train on a treadmill or over ground, and researchers will use computer simulations to measure changes in knee loading.

What this could mean

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

Active substance
haptic biofeedback gait retraining
What this could lead to
If successful, this could point toward a non-drug way to reduce knee joint stress and slow osteoarthritis progression.
What could go wrong
This is a very small, early study (31 people) testing only short-term changes. It is not yet known if the training reduces pain or prevents joint damage long-term.

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 31 people

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

Started

Jan 2024

Expected to finish

Dec 2026

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 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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: * Medial and/or lateral compartment knee osteoarthritis * Diagnosed with knee osteoarthritis of at least six months duration * Ambulatory without aids * Able to walk for at least 60 minutes * Typical pain rating of 1-4 on scale of 0-10 * Able to reduce gastrocnemius muscle activation by 10% from baseline Exclusion Criteria: * History of symptomatic arthritis in lower limb joints other than the knees * Replacement of any lower extremity joint * Symptoms originating from the patellofemoral joint * Body mass index equal to or greater than 35 * Nerve or muscle disease associated with walking difficulty * History of rheumatoid arthritis, gout, or autoimmune disease * History of lower limb fracture or surgery requiring hospitalization * Pregnant
