Dear all..... we all (physios/chiros etc) all have our own pet theories as to which bit is dysfunctional, and consequently our favourite techniques are directed towards them. However, there is more then one way the crack a nut (or treat and Wikipedia reference-linksij! - if you believe in them). The key point for us as therapists is to be open to new ideas and others perspectives, as may not be wrong, they just have a different view.
