Blood flow measure may predict neck pain block success
NCT ID NCT05723380
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
