Suprascapular Nerve PRF for Central Sensitization and Neuropathic Pain

All patients will be monitored with electrocardiography, non-invasive blood pressure, and peripheral oxygen saturation, and peripheral intravenous vascular access will be performed before the procedure. Patients will be placed in a sitting position. The physician will stand behind the patient for the posterior approach. The skin area to be injected will be prepared and covered in a sterile manner using a povidone-iodine-based solution. The operator will use ultrasound (a TOSHIBA Aplio 500 Ultrasound) guidance to perform suprascapular nerve radiofrequency. The suprascapular notch will be visualized. A twenty-two gauge, 10 cm long, and 10 mm active-tipped radiofrequency cannula will be introduced to the suprascapular notch. Motor stimulation will be performed at 2 Hz at a setting of 1 V, and sensory stimulation will be performed at 50 Hz at a setting of 0.5 V. After the needle tip confirmation, pulsed radiofrequency will be applied to the suprascapular nerve for 360 seconds.
