Over the years, my group and I have performed countless research and experimentation projects in order to determine how the spine acts and reacts to applications of external mechanical forces, whether accidentally or purposeful, as a clinical procedure. Further, they are tireless in discharging this duty. The nervous system's righting reflexes and innate organizing energy control all muscles including spinal muscles. When the head gets mis-aligned with gravity, the righting reflexes and innate organizing energy cause the spinal muscles to reorganize and hold the spine below the head into subluxation displacements, or whatever position that is necessary to keep the head as upright as possible relative to gravity. This is the process Pettibon calls reprogramming.
Every patient responds differently to reprogramming and to spinal corrective forces.
An objective examination program, which is taught in seminars, determines the exact amount of weight needed and time needed for reprogramming. In addition, the six spinal units are measured relative to each other and to gravity. Then, spinal dis-relationships can be classified and qualified and corrected. Therefore, all lasting spinal correction must be correlated with spinal rehabilitation procedures that include both vascular and avascular rehabilitation. Vertebrae are totally passive.
