muscle activation technique

Anyone tried this?

I have what seems like never ending muscle and joint pain.  I ruptured my Achilles tendon in March 2008, developed plantar faciitus shortly after rehabbing the tendon, and recently had a scope done to remove plica from my knee. 

I have a friend that says this was a life saver, I really want to try it out, but the 4 certified people in the Houston area are $135 a session, so I wanted to get some input before shelling out that much money.

Thanks!

Tried what?  Is there supposed to be a link to something in this post?

Sorry, I thought it was a widely known approach.
