Pain Physician Vol. 9, No. 3, 2006 To the Editor: We consistently obtain similar clinical outcomes using pulsed radiofrequency (PRF) applications to those reported by Rozen and Parvez (1). In agreement, our clinic has been successfully treating post inguinal herniorrhaphy pain for 10 years using PRF applications to the dorsal root ganglia. Thus, we thank the authors for their report. We do note...

OBJECTIVE To evaluate the short-term effectiveness of pulsed radiofrequency on the dorsal root ganglion (DRG) in patients with chronic refractory cervical radicular pain. METHOD Fifteen patients (13 males, 2 females; mean age, 55.9 years) with chronic radicular pain due to cervical disc herniation or foraminal stenosis refractory to active rehabilitative management, including transforaminal c...

We describe a spectrometer for pulsed ENDOR at 140 GHz, which is based on microwave IMPATT diode amplifiers and a probe consisting of a TE011 cavity with a high-quality resonance circuit for variable radiofrequency irradiation. For pulsed EPR we obtain an absolute sensitivity of 3x10(9) spins/Gauss at 20 K. The performance of the spectrometer is demonstrated with pulsed ENDOR spectra of a stand...

Several classes of nonablative laser and light technologies have been developed to target laxity, rhytides, and the various aspects of photoaging. The combination of the 3 main classes of nonablative rejuvenation, infrared laser, intense pulsed light, and radiofrequency energy, are assessed in the current study. Using a comprehensive grading scale developed to evaluate the multiple categories o...

Persistent and intractable hiccups (with respective durations of more than 48 hours and 1 month) can result in depression, fatigue, impaired sleep, dehydration, weight loss, malnutrition, and aspiration syndromes. The conventional treatments for hiccups are either non-pharmacological, pharmacological or a nerve block treatment. Pulsed radiofrequency lesioning (PRFL) has been proposed for the mo...

BACKGROUND Pulsed radiofrequency (PRF) treatment is defined as the delivery of short pulses of radiofrequency via a needle tip, which does not result in an actual thermal lesions. There are mixed views regarding the use of PRF for trigeminal neuralgia (TN). In our opinion, one of the main reasons for the contrasting views is the insufficient PRF dose employed in previous studies. In a recent st...

In recent years the use of pulsed radiofrequency (PRF) to treat chronic pain conditions has generated intense interest in the pain community. PRF is a minimally invasive, target-selective technique that has reported anecdotal benefit at reducing post-amputation stump pain (1), chronic radicular/ganglion pain (2), neuropathic pain (3), and arthropathic pain (4). There is no published data on usi...

DOI: 10.5812/kowsar.22287523.4047 Implication for health policy/practice/research/medical education: The evidence on PRF treatment of the peripheral nerves is scarce. The currently available evidence should be complemented with well-designed trials. In order to emphasize the importanc...

To the Editor:—First, I would like to congratulate Van Zundert et al. for their efforts to elucidate one of the putative mechanisms associated with pulsed radiofrequency (PRF), which may help us to understand its analgesic effect in clinical settings. Unfortunately, the explicit and implicit critique in the editorial by Richebé et al. about PRF in general may leave readers not familiar with thi...
