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 This study
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 Results may not be published yet.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

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 tested whether the Ghostly app, which guides patients through strength exercises, could help hospitalized people with stroke, COVID-19, frailty, or muscle weakness. Fifteen participants used the app during their hospital stay. The goal was to see if it was practical and could improve muscle strength. This is an early feasibility study, so results are preliminary.

What this could mean

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

Active substance
Ghostly app (strength training exercises with optional blood flow restriction)
What this could lead to
If successful, this could provide a simple, app-based way to help hospitalized patients rebuild muscle strength during recovery.
What could go wrong
This is a very small feasibility study with only 15 participants, so results may not apply to everyone. The app is still experimental and not yet proven to work better than standard care.
