Conditions
Interventions
The intervention which will be studied is Pulsed radiofrequency treatment (PRF) on the dorsal root ganglion (DRG) by patients with radicular neuropathic patients. PRF uses radiofrequency current in sh
the “silent” phase (480 ms) of PRF allows time for heat elimination, generally keeping the target tissue below 42° C for 120 seconds. During the PRF treatment lidocaine will be injected.
