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 Results may not be published yet.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.

Summary

This completed study with 92 people tested whether a measure called perfusion index (a way to check blood flow) can predict how well a nerve block (erector spinae plane block) relieves chronic neck pain from conditions like herniated discs or spinal narrowing. Researchers tracked changes in pain scores and disability after the procedure. The goal was to see if the perfusion index could identify who gets good pain relief.

What this could mean

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

Active substance
erector spinae plane block (nerve block with local anesthetic)
What this could lead to
If successful, this could help doctors predict which patients will benefit from a specific nerve block for chronic neck pain.
What could go wrong
This is a small, completed study looking at a predictive tool, not a new treatment. The results may not apply to all pain types or patients.
