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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests whether Tecar therapy, a non-invasive device that delivers high-frequency electromagnetic energy to deep tissues, can reduce pain and disability in people with lumbar radiculopathy (sciatica). Ninety adults with recent-onset symptoms will be randomly assigned to receive either conventional physical therapy, Tecar therapy plus physical therapy, or a sham Tecar treatment plus physical therapy. Pain levels, function, and mobility will be measured over 12 weeks to see if Tecar provides added benefit.

What this could mean

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

Active substance
Tecar therapy (a non-invasive device that delivers high-frequency electromagnetic energy to deep tissues)
What this could lead to
If it works, this could provide a new, non-invasive option to reduce pain and improve function in people with lumbar radiculopathy.
What could go wrong
This is a small, early-stage trial (90 participants) with no blinding for the physical therapy group, so results may not be conclusive or widely applicable.
