Atlas Orthogonal explained


“A masters university level, post graduate certified, science-based health care discipline correcting body balance and tone through vectored alignment and restored function of the upper cervical spine.”


The major chiropractic premise:

  • the nervous system has a regulating effect over all bodily functions
  • interference to nerve function (including brain and peripheral nervous system incorporating peripheral sense organs such as the eyes, ears and concerning smell) can result in poor health
  • the skeletal system, primarily the spine can interfere with the nervous system via joint subluxation or misalignment

The AO premise:

  • the first and second vertebrae in the neck should line up with the skull (occiput) at right angles or orthogonally.
  • if they are not orthogonal, subsequent imbalance of body structure will eventuate due to compensatory changes.
  • compensatory changes are affected by nervous system interference, irritation or dysfunction.
  • this may lead to poor organ function, muscle spasm causing shoulder or pelvic girdle distortion, over time, if not corrected

How the instrument ‘works’:

Eugene T. Patronis, Jr., Ph.D., professor at the School of Physics, Georgia Institute of Technology describes the operation of the Atlas Orthogonal Adjusting Instrument as follows:

“A mechanical impulse is imparted to the metal stylus by means of a spring loaded plunger. The strength of this impulse is determined by the initial degree of compression given to the plunger spring. The impulse imparted to the stylus by the plunger excites a compressional wave in the stylus. The velocity of this wave in the stylus material is determined by the square root of the ratio of the Young’s modulus to the density of the stylus material. At the patient-stylus interface, dependent on the impedance match, a portion of this wave energy is transmitted into the patient and a portion is reflected back to the plunger.”
