I am not sure there is a specific order to body parts done. However, in general, I like to smash an area first before doing a stretch-type mobilization (ie. banded distraction), on the unproven subjective theory that smashing will increase the pliability of the tissue and then the stretch mob after will bring it to proper or a new length.  my thinking is that smashing after stretch mobs may cause the tissue to revert back to a shorter state due to a potential reaction to the pain in that area from smashing. but like i said – unproven and very subjective. hope this helps.
