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 Results may not be published yet.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

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 using a TENS device before a back injection can lower pain during the procedure. About 52 adults with chronic low back pain will be randomly assigned to receive either active TENS or a sham TENS. Researchers will compare pain scores and satisfaction between the two groups.

What this could mean

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

Active substance
Transcutaneous electrical nerve stimulation (TENS)
What this could lead to
If it works, this could offer a simple, drug-free way to ease pain during common back procedures.
What could go wrong
This is a small, early-stage trial with only 52 people. TENS may not reduce pain more than a placebo, and results may not apply to everyone.

Participants

About 52 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Sep 2028

An estimate. End dates often move.
