The latest treatment using pulsed radiofrequency therapy―Treatment methods and mechanisms using the latest equipment and parameters―

Abstract

Pulsed radiofrequency (PRF) is a treatment method that relieves pain by intermittently applying radio frequency waves to nerve tissue. Unlike radiofrequency thermocoagulation, this method not only can be applied to nerves including motor nerves, but can also be expected to have a therapeutic effect by acting on peripheral nerve axons, so it has the advantage of being widely applicable. Last year, the latest PRF generators were introduced in Japan as well as equipment overseas. PRF has 4 types of frequencies (1, 2, 5, 10 Hz), 5 types of pulse widths (5, 10, 20, 30, 50 msec), A generator was introduced that allows the voltage to be changed arbitrarily from 20 V to 70 V. This article provides an overview of pulsed radiofrequency therapy, the latest equipment, treatments using the latest parameters, and mechanism of action of PRF. In the future, it is hoped that Japan will take the initiative in developing PRF and conducting clinical research.
