Joint movement can be described in 2 main ways. Osteokinematic movement is the movement of your body parts and it’s clearly visible to the naked eye. Arthrokinematic movement is movement that happens inside your joint capsules and cannot be seen.
Your joint surfaces slide, spin and roll across each other. This permits your bones to move through space. Impediments to healthy arthrokinematic movement limits osteokinematic movement. That, or movement happens at the expense of soft tissues and results in wear and tear.
