In the article I didn't see what type of ultrasound they are using. I don't know a great deal about ultrasound, but I do know that there is a difference between diagnostic (imaging) and therapeutic ultrasound systems.

It melted the spasms like butter. Several months of terrible pain gone in an instant. I was never so tempted to steal a machine in my life.
