This is a test block
Flexion movement of the spine strains the layers of collagen in the spinal discs when loads on the spine are small in a healthy way. Movement is healthy and needed for healthy discs under low loads. Light exercises such the cat‐camel motion exercise taking the spine through an unloaded range of motion can benourishing. Thus, there is a time and place for flexion motion. Loads are necessary for healthy tissues but not exceeding tolerance.
When the spine loads are high in magnitude with repeated flexion motion, the collagen fibers delaminate in a cumulative fashion.
Slowly the nucleus of the disc will work through the delaminated walls and create a disc bulge. The greater the load, and the greater the repetitions, the faster this will occur
(Tampier et al, 2007, Veres et al, 2009). Several other events occur depending on the amount of stretch on the spine ligaments at the end‐range of flexion. For example, cytokines linked to acute and chronic
inflammation accumulate with repeated full‐flexion motion exposure (D’Ambrosia et al, 2010).
