is a system of chiropractic spinal analysis and care. Chiropractic biophysics approach to improved patient well-being, as designed by these doctors, is a mechanistic one. To some extent, these mechanistic concepts are justified in that the spine and nervous system have many machine-like qualities. The spine is composed of bones, muscles, blood vessels and neural networks which resemble beams, motors, hydraulics and computers, respectively. Ball and Carlson1 have stated. The use of engineering modeling in biological systems is now commonly accepted as a logical means of approaching highly complex mechanisms.
