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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a small vibrating device placed on the thigh can prevent muscle loss when a leg is immobilized. Forty-two healthy adults will have one leg in a cast for several days. Half will receive daily vibration sessions; the other half will not. Researchers will measure changes in muscle strength and jump performance to see if the vibration helps maintain muscle function.

What this could mean

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

Active substance
focal muscle vibration (device)
What this could lead to
If it works, this could point toward a simple, non-invasive way to prevent muscle loss during bed rest or cast immobilization.
What could go wrong
This is a small, early-stage study in healthy volunteers, not patients. The results may not apply to real-world medical conditions, and the vibration may not prevent muscle loss.

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 42 people

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

Started
