NCT ID NCT07534189

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 This study
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 Results may not be published yet.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.

Summary

This study will follow 300 adults aged 50 and older with knee osteoarthritis who are scheduled for a 3-week thermal spa treatment. Researchers will use wearable sensors to measure knee movement fluidity before and after the spa program, and at 3 and 12 months later. They will also track pain, physical function, and quality of life to see if the spa therapy provides lasting benefits.

What this could mean

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

Active substance
thermal spa treatment
What this could lead to
If it works, this could provide evidence that spa therapy is an effective non-drug option for improving knee movement and reducing pain in osteoarthritis.
What could go wrong
This is an observational study, not a controlled trial, so results may be influenced by other factors. The study is not yet recruiting, and the primary outcome is a movement measure, not a direct symptom improvement.

Participants

About 300 people

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

Expected to start
