The Effect of Sensory Stimulation Threshold on the Efficacy of Pulsed Radiofrequency Applied to the Dorsal Root Ganglion in Patients with Chronic Lumbar Radicular Pain

Lomber dorsal root ganglion pRF is an interventional treatment options in the treatment of lumbar radicular pain. The goal of this study is to investigate the effect of sensory threshold outcomes on pain severity during dorsal root ganglion pulsed radiofrequency (DRG-pRF). It will also learn effects about disability due to chronic LRP. The main questions it aims to answer are:

Does lower sensory threshold result in lower pain scores and chronic LRP related disability?

Participants will:

Take DRG-pRF procedure for 4 minutes. Visit the clinic at 1. and 3. month for questionnaries.
