Alex_arg:
Hi all, i like to ask the forum if anyone of you ever build or work with Electromagnetic Therapy equipment?
Like those published by several europian electonics magazines in the 90's, in form of kits. (Nuova Elettronica).
They assured that is very useful for external treatment of a variety of deseases, and particularly for accelerate broken bones and wounds healing.
They work generating a broadband signal up to 300MHz, and applying it in short bursts (100ms) to an "antenna" or radiating element which is applied close to the affected region of the body.
I'm building one of these units (to treat my noisy knees), but i can't find some background scientific information to backup the effectiveness of this apparatus, so i decided to post it here like a topic, just in case...
I'll aprecciate any information you guys have in this matter.
Thank you.

you want to look for a skenar, they are VERY effective and we own 4 in our family (that is over £ 5K total)

On a slightly related note, I'ce used medical TENS units before but found that they were a novelty item... any perceived therapeutic effect of said device I'd say is probably placebo.

A skenar is indeed a form of tens machine but not to be confused with the passive junk out there. It has software that changes the signal based on the bodies reaction and so is very effective. I have witnessed some remarkable recoveries myself. Some placebo effect is probably taking effect, placebo is a side affect of any form of cure and can be a cure in itself

alm:
A quick PubMed search found this recent review:
Electromagnetic field stimulation for treating delayed union or non-union of long bone fractures in adults
It refers to and does meta-analysis of four previous studies.

At least in the case of fractures, the evidence in favor is not very strong. Based on the current understanding, I see no reason to believe it has any positive effect. The article (full text behind a paywall) also describes several (DC and AC) methods, and claims that although a pulsed field contains a wide spectrum of frequencies, most of the energy is below 1 kHz.
