Figure #1 shows the theoretical position of the adjustor's arms and shoulders when the nail-hand pisiform is on contact and the thrust has not yet been initiated.

Figure #2 shows the theoretical positions of the adjustor's shoulders and arms with the "triceps pull" having been initiated. Note "the contracting of the triceps has caused a straightening (reduction) of the upper-arm/lower-arm angle." This angle has been reduced to 180 degrees by means of the contraction of the triceps.


Ideally, at this point, when the arms have been completely straightened by the "triceps pull," there has been little, if any, travel in the nail-hand pisiform. This lack of travel is accomplished by forcing the nail hand "anatomic snuff box" upward against the hammer-hand pisiform simultaneous with the triceps pull. If done as prescribed, this will continue to yield a very light contact on the patient's neck.


Figure #3 Theoretically, further contraction of the triceps without further travel of the nail-hand pisiform will cause a narrowing of the adjustor's pectoral girdle ( A-B), thus causing a slight, rectilinear travel of the adjustor's nail-hand pisiform. (ideally in the direction of the calculated vector).
