ClinConnect Summary

This clinical trial is looking into a treatment called pulsed radiofrequency (pRF) aimed at helping patients with chronic lumbar radicular pain, which is pain that radiates down the leg from the lower back. The main goal is to see if patients who have a lower sensory threshold, meaning they can feel pain more easily, experience less pain and disability from this condition. In simpler terms, the study wants to find out if how sensitive a person is to pain affects how well this treatment works for them.

To be eligible for this trial, participants should be aged between 65 and 75 and have had pain for at least three months, with a certain level of intensity. They should also have a diagnosis of spinal stenosis or a herniated disc confirmed by an MRI, and have not found relief from other treatments. Participants will undergo the pRF procedure, which lasts about four minutes, and will need to visit the clinic one and three months later to answer some questions about their pain and disability. It's important to note that this trial is not yet recruiting participants.
