Comparing 45 V and 60 V Pulsed Radiofrequency Treatments for Cervical Radicular Pain to Evaluate Pain Relief and Safety of Cervical Dorsal Root Ganglion Procedures

What this Trial Is About

Researchers are evaluating the effects of two different voltage settings, 45 V and 60 V, for pulsed radiofrequency PRF treatment applied to the cervical dorsal root ganglion DRG in patients experiencing cervical radicular pain. This condition involves nerve pain radiating from the neck due to nerve root compression, often following inadequate response to conservative treatments. The study aims to compare pain relief and functional improvement between these two PRF voltage groups, while also monitoring any procedure-related side effects. Participants receive PRF treatment targeted at the cervical DRG under fluoroscopic guidance. Both groups undergo a similar procedure involving local anesthesia and sensory stimulation to confirm correct needle placement. The PRF is then applied for 240 seconds at a maximum temperature of 42C, with either 45 V or 60 V applied depending on the assigned group. After the procedure, patients are observed for 60 minutes before discharge. The study uses a randomized, parallel design to compare these two active treatment groups. Participants pain levels are measured using the Numerical Rating Scale NRS, and functional disability is assessed with the Neck Disability Index NDI before treatment and at 3 and 6 months afterward. Researchers also record any adverse events related to the procedure throughout the follow-up period. This allows assessment of both the effectiveness and safety of each voltage setting. The total study duration spans from the initial treatment through the 6-month follow-up assessments.
