NCT ID NCT07281638

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
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 Results may not be published yet.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 This study
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This status has not been confirmed recently, so it may be out of date.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 a portable exercise bike that clamps to hospital beds, allowing patients to pedal their arms and legs while lying down. The goal is to see if using the bike for at least 15 minutes a day can help prevent muscle loss, weakness, and other problems like blood clots and confusion. The study will include 80 adult patients expected to stay in the hospital for at least 3 days, and will track how often they use the device, any safety issues, and whether it improves their recovery.

What this could mean

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

Active substance
Bedside Bike (a portable exercise device for bed)
What this could lead to
If it works, this could offer a simple, safe way for hospital patients to maintain muscle strength and reduce complications like weakness and blood clots.
What could go wrong
This is a small, early-stage quality improvement study with only 80 participants. The device may not be used enough to show clear benefits, and results may not apply to all hospitals.

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.

Expected to start

Jul 2026

An estimate. Start dates often move.

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 to 110 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
