In our last entry, we described and illustrated the fundamental "triceps pull" Grostic/Nucca adjustment. This was done with a simple line drawing depicting the positions of the arms and shoulders at the beginning and the end of the thrust. Now, let's substitute actual human anatomy –- hand, arms, shoulders –- for the line drawing.

In order for the theoretical, vectored, rectilinear force, or anything approaching a rectilinear force, to be delivered, the arms would have to be completely straightened at the end of the thrust.  With the arms completely straightened, the hammer-hand pisiform would have to remain securely locked in the "anatomic snuff-box" of the nail-hand and positioned directly above the nail-hand pisiform at the completion of the thrust. Also, as taught by Dr. Grostic, in order to pinion the arms together, the ring finger of the hammer-hand should be locked around the nail-hand wrist just inferior to the head of the nail-hand ulna.

We suggest you try this.

If this cannot be accomplished, then the line drawing that we published in our last entry does not relate to the actual function of the human anatomy (the adjustor's anatomy), and obviously the force produced by the adjustor would not in any way approach a vectored, rectilinear force.

Therefore, all previous steps –- X ray tube alignment, X-ray placement, X-ray analysis, table placement, etc. -– leading up to the adjustment would amount to a series of worthless exercises.

This does not mean that beneficial results are not obtained by the adjustment.  It simply means that the steps taken prior to the delivery of the adjustment were of a quasi-scientific nature.
