Descrição detalhada
Pulsed radiofrequency (PRF) applied to the dorsal root ganglion (DRG) is a well-established minimally invasive treatment for patients with cervical radicular pain who do not respond adequately to conservative management. Although PRF has demonstrated favorable efficacy and safety, the optimal procedural parameters, particularly the applied voltage, remain uncertain. Previous studies have reported conflicting findings regarding the influence of voltage on treatment outcomes, with some suggesting improved long-term pain relief with higher voltages, while others have associated lower voltage settings with better clinical results. More recent evidence has shown favorable outcomes with higher-voltage PRF in cervical radicular pain; however, direct comparisons between commonly used voltage settings, such as 45 V and 60 V, are lacking.
The primary aim of this study is to compare the effectiveness of 45 V and 60 V PRF applied to the cervical DRG in patients with cervical radicular pain using the Numerical Rating Scale (NRS). Secondary aims include comparing functional outcomes using the Neck Disability Index (NDI) and evaluating the safety of both treatment protocols by comparing the incidence of procedure-related adverse events.
Patients who have undergone cervical DRG PRF for cervical radicular pain and completed their treatment will be evaluated according to the voltage applied during the procedure (45 V or 60 V). Pain intensity will be assessed using the Numerical Rating Scale (NRS), and functional disability will be evaluated using the Neck Disability Index (NDI) before treatment and at 3 and 6 months after the procedure. In addition to between-group comparisons, changes from baseline within each group will also be analyzed. Procedure-related adverse events will be recorded throughout the follow-up period.

Comparador Ativo: 45 V cervical DRG pulsed radiofrequency group
45 V pulsed radiofrequency applied to the cervical dorsal root ganglion for the treatment of cervical radicular pain.
|
After standard hemodynamic monitoring, the patient was placed in the supine position, and the cervical region was prepared using sterile technique.
Under fluoroscopic guidance, the target cervical neural foramen was identified in anteroposterior and lateral views.
Following local infiltration with 2 mL of 1% lidocaine, a radiofrequency cannula was advanced to the target cervical dorsal root ganglion.
Correct needle placement was confirmed fluoroscopically and by sensory stimulation, which elicited concordant paresthesia in the corresponding dermatome.
Pulsed radiofrequency was then applied for 240 seconds at a maximum temperature of 42°C using a voltage of 45 V.
After completion of the procedure, the cannula was removed, a sterile dressing was applied, and patients were observed for 60 minutes before discharge.
