Pulsed radiofrequency is the technique whereby radio frequency (RF) oscillations are gated at a rate of pulses (cycles) per second (one cycle per second is known as a hertz (Hz)). Radio frequency energies occupy 1.0 × 10 4 Hz to 3.0 × 10 11 Hz of the electromagnetic spectrum .
Diathermy equipment typically operates in the short-wave radio frequency (range 1–100 MHz) or microwave energy (range 434–915 MHz). [citation needed] Pulsed electromagnetic field therapy (PEMF) is a medical treatment that purportedly helps to heal bone tissue reported in a recent NASA study. This method usually employs electromagnetic ...
Pulsed radiofrequency ablation relies on delivering an electrical field specifically to neural tissue in order to damage it while minimizing injury to the surrounding area. For example, this technique has been used in patients with chronic shoulder pain as a way to perform a neurectomy of the suprascapular nerve with less risk of damage to ...
Pulsed radiofrequency has also been successful in treating a refractory case of pudendal neuralgia, but additional research is needed to study the effectiveness of pulsed radiofrequency on treating pudendal nerve entrapment. [35]
A nerve root (Latin: radix nervi) is the initial segment of a nerve leaving the central nervous system.Nerve roots can be classified as: Cranial nerve roots: the initial or proximal segment of one of the twelve pairs of cranial nerves leaving the central nervous system from the brain stem or the highest levels of the spinal cord.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Pulsed radiofrequency, neuromodulation, direct introduction of medication and nerve ablation may be used to target either the tissue structures and organ/systems responsible for persistent nociception or the nociceptors from the structures implicated as the source of chronic pain.
On nerve conduction studies, the pattern of diminished compound muscle action potential and normal sensory nerve action potential may be seen given that the lesion is proximal to the posterior root ganglion. Needle EMG is the more sensitive portion of the test, and may reveal active denervation in the distribution of the involved nerve root ...
