The Ideal Spinal Model

IDEAL SPINAL MODEL

Dr. Donald Harrison, the founder of Chiropractic BioPhysics, proposed the Harrison Spinal Model in the early 1980s.  His spinal model is based on mathematical equations that describe the anatomical design of a healthy, well-formed spine. The Harrison Spinal Model is an evidence-based model supported by peer-reviewed research by which chiropractors can evaluate their patients’ spinal alignment.



The Harrison Spinal Model shows both the Ideal and the Average geometric shapes for spinal curves from the side. The neck’s (cervical spine) geometric shape should resemble a piece of a circle, the ribcage (thoracic spine) should be shaped like an oval, and the low back (lumbar spine) should be an oval-elliptical shape. The Harrison Spinal Model has been proven to identify patients in pain versus patients without pain just by looking at their spinal x-ray shapes.[1]

Why are these spinal curves so important? Because they provide:
·      Strength of Structure - The three curves of the spine work to increase stability and strength, creating a dynamic, weight-bearing column that can withstand heavy loads.
·      Shock Absorption – The spine also acts like a spring. It absorbs shock, while loss of curves leads to increased susceptibility of disc injury and vertebral fractures. Discs are NOT shock absorbers—if any doctor explains them to you as such, it’s a red flag and shows that they don’t understand basic hydrodynamics.
·      Room for Organs – The correct spinal curvature allows space for your organs to live, which is especially vital for lung capacity.
·      Balance/Stability - Spinal curves also maintain the body’s balance, helping the spine withstand great amounts of stress by providing a more even distribution of body weight.
·      Ability to Move - It enables movement so that you can reach, pull, and/or contract.
·      Protection of your Nervous System - Last, but certainly not least, a spine with the proper curves protects your spinal cord. The Lordotic curve decreases the overall length of the spinal column, the space where the CNS lives. When stretched, nerves are compromised, so the Lordotic curve is important to allow slack in the spinal cord. As Doctor Alf Breig stated, “Loss of cervical curve stretches the spinal cord 5 to 7 cm and produces pathological tension, putting the body in a state of disease.” “Spinal bone misalignment can reduce nerve impulses by 60%.”[2]

God has created a complex anatomical system that we as humans don’t fully understand; there may be other reasons for spinal curves that are yet to be discovered. Our goal at Living Well Family Chiropractic is simply to get you as close to your natural spinal structure as possible.
