Actually
Vito, it's not as crazy as it sounds.
Pulsed Electromagnetic Field Therapy is a proven therapy for fractures and there is evidence for it's use in soft tissue injuries.
I had a bone growth stimulator after my accident as my femur wasn't healing. Hard to tell how much it helped as I was non-weight bearing and that delays healing.
Be aware, the magnets
Vito uses are
dangerously strong. Magnets of more than a few centiimeters in diameter can crush tissue and even break bones. Be very careful with pairs or getting near metal.
