Once the needle reaches the lateral edge of the pedicle shadow, the C-arm will be adjusted to a lateral view to confirm that the needle is located at the craniodorsal portion of the intervertebral foramen. Sensory stimulation will be delivered through the RF generator at 50 Hz, and paresthesia will be sought in the corresponding dermatome at values between 0.4-0.8 mA.\n\nAfter achieving paresthesia, motor stimulation at 2 Hz will be applied, and the location near the DRG will be confirmed if motor stimulation is not elicited at values less than 1.5 times the sensory threshold. Pulsed RF will then be applied for 4 minutes at a setting of 45 V, 20 ms pulse width, and 2 Hz frequency. Following the application, needle will be directed slightly anterior and after appropriate contrast flow, dexamethasone will be injected.",[9],[19],{"name":20,"affiliation":21,"role":22},"Güngör Enver Özgencil, MD","Ankara University Medicine Faculty Anesthesiology and Reanimation Department","STUDY_DIRECTOR",[24,29],{"name":25,"role":26,"phone":27,"phoneExt":10,"email":28},"Hanzade Aybuke Unal, MD","CONTACT","+905057179039","hanzadeunal@windowslive.com",{"name":30,"role":26,"phone":31,"phoneExt":10,"email":32},"Ersin Sönmez, MD","+905370257858","ersins@outlook.com",{"type":34,"investigatorFullName":35,"investigatorTitle":36,"investigatorAffiliation":5,"oldNameTitle":10,"oldOrganization":10},"PRINCIPAL_INVESTIGATOR","Hanzade Aybuke Unal","Principal Investigator","100574254","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-100574254",false,"NCT06756893","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","The Effect of Sensory Stimulation Thresholds on the Efficacy of Pulsed Radiofrequency Applied to the Dorsal Root Ganglion in Patients with Chronic Lumbar Radicular Pain","Inclusion Criteria:\n\nPain lasting ≥3 months NRS score ≥4 Unilateral pain Diagnosis of spinal stenosis or lumbar disc herniation causing root compression, confirmed by magnetic resonance imaging (MRI) according to appropriate diagnostic criteria and classification Failure of conservative treatment\n\nExclusion Criteria:\n\nUnwillingness to participate in the study Epidural steroid injection within the past month Uncontrolled psychiatric disorders despite medical treatment Systemic or localized infection signs at the procedure site Severe spinal stenosis Allergy to steroids or contrast agents History of cancer Coagulopathy","ALL","18 Years","80 Years",{"count":48,"type":49},150,"ESTIMATED","OBSERVATIONAL","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:\n\nDoes lower sensory threshold result in lower pain scores and chronic LRP related disability?\n\nParticipants will:\n\nTake DRG-pRF procedure for 4 minutes.
