2 Key Principles of Spinal Mechanics

Master These Two Spinal Principles—And Everything Starts to Make Sense: Form Reflects Function: The spine has evolved with intentional variation in shape and size. Cervical vertebrae are smaller and more mobile to allow for head movement, while vertebrae increase in size lower down to support greater loads through the thoracic and lumbar regions. The Power of the S-Curve: The spine’s natural sinusoidal (S-shaped) curve isn’t random—it’s a brilliant design that balances strength, shock absorption, and flexibility. This curvature allows the spine to efficiently transfer force and adapt across a wide range of movement demands.
