What is the cumulative injury cycle?
Cummulative injury can be explained by the law of repetitive motion. In this model: Tissue injury=#of repitions X force of each repition/amplitude of each repition X rest between each repition What this means is that anytime we do something too much and too often with our bodies without proper rest , even at low intensities, injury will occur (ex. Sitting at a computer for more than an hour at a time). Once this process is started it is a slippery slope into chronic neck and shoulder pain. Getting At the Root cause Researchers have discovered that the most pain sensitive structure in our spines is the outer layers of the discs. Theses outer layers are known as the annulus fibrosis. When the disc is subjected to irritating mechanical forces such as forward leaning postures it will let us know by neck and shoulder stiffness and pain. It will also cause the disc to flatten out and dry up which creates compressive forces on the joints from which we move our necks. When the joints are subje
