What is Rolf?

I mentioned in an earlier post that I am considering acupuncture/acupressure to help with my anxiety and panic attacks. As I've been researching possible benefits I have come across other techniques as well. I found this article today,http://www.naturalhealthmag.com/fitness/mind-body/lose-pain, and am wondering if anyone has ever heard of Rolf and has been treated by this technique. What are your thoughts/experiences?
