Wikipedia reference-linkPulsed electromagnetic field therapy (PEMFT) has been used for decades to assist delayed fracture healing. We used to have someone on it almost all hours of the day when I worked in a large state athletic practice in Sydney. I have always wanted one for the clinic in London although I would only have a rare occasion to use it here. They typically set you back a few thousand £'s. Maybe you are looking at a different device as the one I have has no time limit as such on it. It is plug it in, wrap it around the limb and read the paper.

I found this link on the web although I have not read it to see if it in itself is a marketing tool - Buyer's Guide to Pulsed Electromagnetic Fields (PEMF) - Dr. Pawluk
