Flat Back Syndrome: When Your Lumbar Curve Disappears
By Eileen Durfee, inventor & Nationally Certified Spinal Fitness Specialist
Flat back syndrome is exactly what it sounds like: the natural forward curve of the lower back (lumbar lordosis) has flattened out. The result is a spine that looks straight from the side but has lost the mechanical advantage that curve provides.
The lumbar curve is a force-management feature. With it, the low back handles load, generates leverage, and lets you stand and move with less muscular effort. When it flattens, lever arms lengthen, the muscles work harder to hold you up, and the structure becomes easier to fatigue and strain.
This is not a cosmetic detail. When two people generate force — one with a proper lumbar curve, one with a flat back — the curved spine has the better lever system. That comparison, made by examining the two joint lever systems under load, was peer-reviewed by the National Strength and Conditioning Association: the curve is stronger.
The 5-step Spinal Fitness system restores the curves that carry load.

It can raise muscular effort and joint load, which many people experience as fatigue or discomfort. Whether it is the cause of a given persons pain is a medical question.
