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 Results may not be published yet.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
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

Summary

This study tested a special Tai Chi program that uses real-time biofeedback to help people with knee osteoarthritis reduce joint strain. Fifteen adults with knee pain participated, and researchers measured changes in knee joint load after four weeks. The goal was to see if this approach is safe and feasible, and whether it could lead to better pain management and mobility.

What this could mean

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

Active substance
Tai Chi exercise with real-time biofeedback
What this could lead to
If it works, this could point toward a safer, drug-free way to reduce knee pain and improve mobility in people with knee osteoarthritis.
What could go wrong
This is a very small feasibility study with only 15 participants, so results may not apply to everyone. The approach is still experimental and needs much larger trials to confirm any benefit.
