Flatback syndrome is a condition that affects the natural curvature of the spine. The human spine has four natural curves. These curves allow the individual to stand straight and be well balanced. They also make it easier to move or walk with minimal effort.

There are two lordotic and two kyphotic curves. They alternate to form an "S" shape when viewed from the lateral side. The lordotic curve refers to the spine that curves inward, while the kyphotic curve represents the spine that curves outward.
