We have observed multi-photon resonances in a system with a spin 3/2 irradiated simultaneously by a multiple pulse radiofrequency sequence and a low frequency field swept in the range 0-80 kHz. The used excitation scheme allowed us to measure the effective field of the radiofrequency sequence. A peculiarity of this scheme is that the intensity of the resonance lines decreases slowly with the mo...

PURPOSE The objective of this study was to retrospectively evaluate the analgesic effects of continuous radiofrequency lesioning of the suprascapular nerve (SSN) for chronic shoulder pain. The authors sought to obtain insight into the time-sensitive analgesic success and complications of this therapy. PATIENTS AND METHODS This study was a retrospective case series involving patients with unre...

Patients may develop serious eye complications after continuous radiofrequency thermocoagulation (CRF) for V1 (ophthalmic division) trigeminal neuralgia (TN) at a higher temperature. Therefore, the temperature of clinical CRF for V1 TN has long been disputed, but there have few reports been found about how to achieve satisfactory pain relief, reduce the incidence rates of complications, and sho...

In an article published in the August 2015 issue of WORLD NEUROSURGERY, Tenser argues that the occasional reactivation of Herpes simplex virus (HSV) after surgical treatment of trigeminal neuralgia provides insights into the mechanism for efficacy of these operations. Specifically, he argues that because HSV reactivation has been observed in ablative treatments (radiofrequency lesions, glycerol...

It has been suggested that PRF might possibly have an effect on the immune cells. We considered using the intravenous route to apply PRF in conditions that are caused by an unresolved immune action or connected to allostatic load, implicating an abnormally reacting immune system to obtain a systemic effect that could possibly be an additional tool in treating some of these conditions. These man...

Implication for health policy/practice/research/medical education: PRF was initially regarded as a method of blocking nociceptive stimuli that is less destructive than a thermolesion. Since the introduction of the intra-articular application this concept has changed. PRF is now thought to have an anti-inflammatory effect on the immune system, acting on the nociceptive process itself instead of...
