First, it must be understood that the human body is a biomechanical marvel.  Each and every movement is created by a vast interconnected network of biomechanical anatomical structures such as muscles, tendons, and joints.  The body attempts to regulate the biomechanical motion by symmetrically distributing the biomechanical force to all the surrounding joints and soft tissues structures.  Because there are so many anatomical structures involved in creating a single biomechanical movement at a joint, there are a multitude of joints and soft tissue structures that absorb the biomechanical force of a movement or straining posture.

Repetitive movement or sustained postures often create asymmetrical loading of these biomechanical forces within the motion or posture.  This results in joints and muscles in the area to become overstressed and ultimately fatigued which then creates symptoms in the area, but also can be felt to spread to the surrounding compensating anatomical structures.  This leads to the human body experiencing pain and reduced mobility, and over time functional deficit and reduced functional endurance.
