Reflex test may help predict pain procedure success
NCT ID NCT02774694
First seen May 23, 2026 · Last updated Jun 20, 2026 · Updated 4 times
Summary
This observational study is testing whether measuring the nociceptive flexion reflex (a spinal reflex) can predict which patients with chronic back or neck pain will get significant pain relief from interventional procedures like epidural injections or nerve blocks. Researchers will measure the reflex threshold using a device called Paintracker and compare it to pain reduction at 1 week, 1 month, and 3 months. The study aims to improve patient selection for these common but variably effective treatments.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help doctors identify which patients are most likely to get pain relief from injections or nerve blocks, making treatment more personalized.
What could go wrong
This is an observational study, not a treatment trial. The reflex test may not accurately predict outcomes, and the study is currently suspended, so results may be delayed or never completed.
