45 V versus 60 V Pulsed Radiofrequency for Cervical Dorsal Root Ganglion 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

adults with unilateral cervical radicular pain not responding to conservative care will be treated with either 45 V or 60 V pulsed radiofrequency to the cervical dorsal root ganglion. The study will compare pain scores on the Numerical Rating Scale and neck function using the Neck Disability Index, plus track procedure-related safety. The trial aims to clarify which voltage setting provides better pain relief and functional outcomes with acceptable safety. Results may guide parameter choices for PRF in this condition.
