High-voltage pulsed radiofrequency treatment for chronic lower back pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effectiveness of high-voltage pulsed radiofrequency (PRF) on patients suffering from chronic lumbar radicular and neuropathic pain. It is a prospective, double-blinded, and randomized controlled trial designed to compare the outcomes of high-voltage PRF against standard PRF. Participants will be carefully selected based on specific inclusion criteria, including the presence of unilateral pain and confirmation of symptoms through MRI and EMG. The goal is to determine if high-voltage PRF can provide better pain relief and functional improvement for these patients.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Patients over 18 years of age.
* Unilateral pain radiating to the lower extremity (with or without lumbar pain), which clinically corresponds to the path of the corresponding dermatomes.
* Correlation between clinical symptoms and lesion observed by magnetic resonance imaging (MRI).
* Radicular syndrome of three months or more of evolution.
* Normal or pathological electromyogram (EMG).
* Pain with neuropathic characteristics confirmed by the DN4 neuropathic pain questionnaire.
* Patients with a previous positive block diagnosis.
* Patients who have signed the informed consent document.

Exclusion Criteria:

* Patients under 18 years of age.
* Patients with non-radicular low back pain.
* MRI not consistent with the patient\'s symptoms.
* Patients with peripheral neuropathy of the lower extremities.
* Patients with a history or current diagnosis of serious mental disorder.
* Patients with moderate or severe cognitive impairment, or evidence of acute or subacute confusional syndrome.
* Infection at the puncture site.
