I say this being discussed over at Blazersedge, and I have to say it sounds like Brandon Roy's issue to a T. http://www.active.com/triathlon/Art..._muscle_tears_with_cross-friction_massage.htm
I'm lukewarm on the "chronic muscle tear" terminology (most hamstring tears are really just strains), but Noakes is a very well respected source and the treatment is spot on, and that's really the most important part of the article. Here's the way it was described to me by a great therapist... I consider it to be much more accurate and better illustrates what the treatment is trying to accomplish, which in turn makes the treatment more precise and more effective. The ball of tension associated with a strain/pull/tear is basically a clenched fist protecting a tender area. Most of the work and pain goes into getting that fist to open up and expose the area that needs treatment. Once you get it to release, it's generally fairly smooth sailing. That's why I said in the other thread that the effectiveness of treatment doesn't really depend on the severity of the injury. Acute or chronic, it's the same process and often a similar time line.
