Summary

The goal of this interventional study is to compare efficacy of either standard versus supra-voltage radiofrequency cervical epidural injection in pain alleviation in population with chronic cervical radiculopathy.

Conditions

• Chronic Cervical Radiculopathy

Interventions

Type	Name	Description
DEVICE	radiofrequency high voltage	nvolved a high voltage PRF technique, where the voltage started at 65 V and could be adjusted up to 80 V based on patient tolerance. Both protocols involved two cycles of PRF application, with each cycle lasting 240 seconds and comprising alternating periods of current application and deactivation. The pulse rate frequency was set at 2 Hertz (Hz), resulting in two active phases/second (20 milliseconds (ms) of current application followed by 480 ms without stimulation)
PROCEDURE	standard RF	A standard voltage PRF technique, administering PRF at a fixed voltage of 45 volts (V)
