I'll ask at my appt next week.
The one I mentioned about dropping the top ribs is generally called rib mobilization.
A I don't know if the chiro version is just called a top rib adjustment.
He has done little adjustments to my elbows too when they were hypersensitive and bothersome.

the video link I posted the about the deep tissue massage has a section similar to the new thing my chiro has been doing -the position is with my arm around across my lower back and he works around the shoulder and scapula.

Then last month when my neck was tight he did a deep thumb pressure tension on the muscles - stretching downward - it was pretty firm pressure on those - but it did the trick. {levator scapulae, SCM & scalenes most likely}
