After viewing the adjusting stances of the Grostic/NUCCA practitioners that have appeared recently on the Internet and in The Upper Cervical Subluxation Complex, it seems appropriate that we review on ONCAUSE the fundamental mechanics of the Grostic/NUCCA adjusting positions.

The very clever concept of using the human body as a well coordinated and precisely aligned machine -– a machine, which, if aligned properly and placed in the proper position, could deliver a rectilinear force along a calculated vector -– was devised by Dr. J. F. Grostic, Sr.

In our next entry, we will depict the correct (according to J.F.G.) positioning of the adjustor's legs, hip, spine and shoulders when positioned to deliver a Grostic/NUCCA adjustment.

We will show the correct doctor positioning for the “settle-back” in the three anatomical planes in the following order: 1) Coronal, 2) Sagittal, 3) Transverse.
