Clinical trial for Chronic Low Back Pain (CLBP)
Official title A Superiority Trial of Radiofrequency Ablation for Low Back Pain
ClinicalTrials.gov ID: NCT07222462
What this study is testing
- What it's testing
- The study aims to find out if a specific type of heat-based nerve treatment is more effective than a simulated procedure for relieving chronic low back pain.
- Who it's for
- The study is looking for people who have chronic low back pain.
- What's involved
- Participants will be randomly assigned to receive either a real heat-based nerve treatment using one of two electrode types, or a simulated procedure that looks like the treatment but does not deliver heat.
- Time commitment
- The source text does not specify the total duration of the study or the number of visits required.
This is a blinded study.

Who can take part
Ages 18 and older
You may be able to join if
- Age ≥18 years
- CLBP of duration ≥ 3 months. Low back pain is defined as occurring between the lower posterior margin of the rib cage and the horizontal gluteal fold.
- Low back pain intensity numerical rating scale (NRS) ≥ 4 with one of the following prior to LRFA: 1) Current low back pain intensity, 2) Average pain...
- Has had conservative treatments for CLBP (physical therapy, exercise therapy, spinal manipulation, massage, acupuncture, etc.)
- Candidate for unilateral LRFA (L1-S1 joints; ≤3 levels); or bilateral LRFA (L1-S1 joints; ≤2 levels)
You likely can't join if
- CLBP attributed primarily to specific spine-related conditions (radiculopathy, lumbar spinal stenosis, spinal instability), 'red flag' conditions...
- Prior LRFA
- Prior lumbar facet joint (intra-articular or medial branch nerve) corticosteroid injections (past 6 months)
- Surgery involving one or more of spinal levels where LRFA is to be performed, in the past 2 years
- Lumbar fusion involving the spinal levels where LRFA is considered, at any time
- Prior known severe lumbar central canal stenosis on MRI as defined by Lee (2011): obliteration of the cerebrospinal fluid (CSF), and marked...

- Prior formal diagnosis of fibromyalgia by a rheumatologist (diagnosis by primary care physician or pain medicine specialist is not sufficient)
- Unstable psychiatric or terminal medical conditions that would limit study participation and the likelihood of follow-up for 12 months post-randomization
- Pregnancy, being a prisoner, or having a prior formal diagnosis of cognitive impairment by a neuropsychologist or neurologist, confirmed by health record documentation
- Participant report of prior formal diagnosis of cognitive impairment by a neuropsychologist or neurologist can be obtained, but participant-reported cognitive impairment by a neuropsychologist or neurologist must be...
