| Label | Type | Description | Intervention Names |
|---|---|---|---|
| pulsed radiofrequency | Active Comparator | sensory stimulation will be carried out at 50 Hz. The definitive position of the electrode will be verified by inducing paresthesia with sensory stimulation between 0.1-0.3 V in the affected painful area, then pulsed radiofrequency will be applied for 10 patients for 10 mins |
|
| thermal Radiofrequency | Active Comparator | sensory stimulation will be carried out at 50 Hz. The definitive position of the electrode will be verified by inducing paresthesia with sensory stimulation between 0.1-0.3 V in the affected painful area, then Thermal lesion will be applied for 10 patients for 2 cycles of 90 seconds |
