What is PEMF?

Many of you are likely aware that CFE carries the Assisi Loop. But what is it? What does it do? How does it work?

This topic is anything but quick and simple, but we’ll try to stick with the basics. PEMF stands for Pulsed ElectroMagnetic Field therapy, used to induct electricity into cells to create changes. It is a combination of electrical and magnetic fields. There are references to magnetic therapy (“magnetic stones”) in Hindu therapies around 4000 BC and The Yellow Emperor’s Classic of Medicine around 2000 BC, so these ideas are not new (1). At the end of the 1800s, Nikola Tesla used large coils to treat conditions without physical contact, hence “Tesla” as the unit for measuring magnetic field strength (2). Over time, PEMF therapy has been modernized to allow for the extremely safe, non-invasive, non-thermal treatment available today. Different types of devices are available, which differ in the shape and strength of the electromagnetic waveform emitted, the size and geometry of the antennas used, and the duration and frequency of treatment application. These specifics do appear to be important in efficacy of treatment. PEMF was first approved by the FDA in the 1980s in the form of bone growth stimulators, which are used to treat delayed and non-union bone fractures. In the 1990s, the devices were modified for soft tissue therapy (3).
