PEMF stands for Pulsed Electromagnetic Field. Devices that utilize PEMF technology emit electromagnetic waves at different frequencies in order to stimulate and encourage your body’s natural recovery process.

I have had this done to me. I went in for a very bad upper back/neck issue and walked out with no pain in my back but now it felt like my arm was cut off with a chainsaw and stapled back on. The feeling is strange, you get this heavy pulse deep inside the body from the organs being stimulated.
And it works.
