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 Results may not be published yet.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.

Summary

This study tests whether using blood flow restriction cuffs during low-intensity stationary cycling can safely improve muscle strength and mobility in older adults recovering from a hip fracture. Sixty hospitalized patients over age 65 will be randomly assigned to either real or sham blood flow restriction while cycling. The goal is to find a gentler alternative to heavy weight training for frail seniors.

What this could mean

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

Active substance
Blood flow restriction device (cuffs) used during stationary cycling
What this could lead to
If it works, this could offer a safer way for frail older adults to rebuild muscle and mobility without heavy weights.
What could go wrong
This is a small early-stage trial with only 60 participants, so results may not apply broadly. The intervention involves restricting blood flow, which carries risks like bruising or clotting in vulnerable patients.

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

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

Started

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.
