The rule of the artery is supreme 3. The unity of the human being 1. Interdependent Life is a dynamic process in which change is the only constant and so its main characteristic is motion. Free movement between the body structures is essential for the health of an individual. When it is disrupted the function is in some way disturbed.
Disrupted movement is the altered state that comes about before disease emerges.
When we use the term structure, we mean the muscles, bones ligaments, organs, and fascia. By the term function, we mean the way in which all the different parts of the body work within themselves and in relation to each other. The relationship between structure and function applied in a therapeutic context is probably the greatest contribution made by Andrew Still to medicine. A very good example of this relationship is the young, growing brain. The amount of varied activity that stimulates the brain to work also influences the rate and quality of the growth of the brain tissue itself.
